Just a clarification, Bluetooth 5.2 by itself will not be enough to support LE Audio. There will be new specifications that will implement the profiles on top of Bluetooth 5.2 in order to support the different audio use cases. Also Bluetooth 5.2 was released alongside the new LE Audio announcement today (January 6, 2020).
This is interesting but I don't fully understand what you mean by "implement the profiles on top of Bluetooth 5.2 in order to support the different audio use cases"? Does this mean the chipsets that have 5.2 will require a firmware update or something? Thanks
Basically, the 5.2 specification lays out the foundation for LE Audio, which primarily includes what’s known as Isochronous Channels (needed to support streaming use cases). However, the specifications that define the upper layers which utilize the new features introduced in 5.2 for LE Audio use cases are not available yet and will be released later this year. In order for companies to implement a standard that allows interoperability between devices (e.g. headphones from manufacturer A working with a TV from manufacturer B), they need to abide by a common specification which is what these “Audio Profiles” will provide. So, I believe what you’ll see is that chipset manufacturers will not release a 5.2 Bluetooth chipset that says it’s LE Audio-compatible before these profiles are implemented (don’t quote me on that, though) Keep in mind that the features in 5.2 that provide the support for LE Audio are in fact optional, so not all 5.2 chipsets will ends up spring LE Audio.
@@mohammadafaneh3481 , When you say profile, is it like going to be new Bluetooth profile like HFP, A2DP. Is LC3 tied up to LE audio. I mean would LC3 make it into classic audio as another version A2DP. I mean does the mobiles(source) that are on v5.0 can take advantage of new features(assuming the sink is 5.2 device) by upgrading profiles just through software.
@@saiki4116 AFAIK, they will not back port to A2DP and classic BT protocols. LC3 is a very efficient where the audio is stereo quality atop BLE protocol.
This is quite cool and really excited for this in terms of audio quality as someone who pretty much abandoned wired audio. Thanks for the awesome video.
my Moto X4 already has Tempow's Bluetooth broadcasting stack, called Wireless Sound System. it allows linking up to 4 separate Bluetooth speakers, and each can have designation as mono, or stereo, or left channel, or right channel.
This is awesome! Me and my friend grab a few beers and head to my terrace in the evenings but we always listening to music with reduced volume. This will change our drinking sessions. I am excited. Now, just need a phone and earbuds that support this. Hope LG can push it in the next V series device.
It's two years later! I see cheap headphones claiming support for Bluetooth 5.2 and 5.3, but I haven't seen any supporting broadcast or LC3. Is anyone aware of products that support these? There was a recent announcement of Auracast. Any idea when these will become common?
can't wait! Just bought a Bluetooth adapter for my tv with two separate streams... For late night viewing.. And quite enjoy being able to use my big headset for cozy long time bingeing... or my ear buds for casual watching
I really would like to know the thought processes here. Why a new codec? We have royalty free codes like opus and (if that is to complex) vorbis. But even more interesting (imo) is if they finally fixed bidirectional audio. The 16 khz Audio quality while talking to someone is barely acceptable in the current standard. That is what needs to be fixed the most.
Here is an interesting question for you to answer Gary... I looking for to buy a car radio Bluetooth receiver..mainly for streaming spotify from my iphone 11 pro max so I am between two of them one has Bluetooth 3.0 the other 4.0 LE Question is,will theoretically 3.0 make my phone's battery drain faster than 4.0? or have any speed deference? If so,is it worth it to pay more for a receiver with Bluetooth 4.2 since my phone has 5.0? keep up with this type very interesting topics that you can explain better than anyone else in this platform!!
I have a macbook pro 2012 and Beats solo3 headphones. I think the computer bluetooth chip is 4.0. The computer constantly disconnects from the headphones, which are 4.2. It is so annoying so I have to use the wire. I've seen a video where you can upgrade the computer to 4.2. I wonder if that would fix it. Seems expensive though the part is $150. Also, when I use voice memos on the mac or iphone and I want a quality recording, I have to use a wire. The bluetooth recording sounds like a low quality phone call. Does the Bluetooth tech even exist or will exist to solve that problem of wireless quality recording? Does LE solve this? I wonder if you have any insight. Thanks for the info.
But the most important point is: does LE Audio support bidirectional audio? Can we expect that there will be headsets which use LC3 codec for both speakers and mic?
Screw battery life savings, when the hell will we be able to use high quality stereo channels and a microphone at the same time!? I think it's ridiculous that we still have such a limitation after the bandwidth improvements from BT 5.0.
I don't understand. What setup are your referring to? I use a Bluetooth headset with a microphone often. But that has nothing to do with BT 5.0. BT 5 was all about BLE not Classic.
@@GaryExplains I see, but still, didn't BT5 come with a big bandwidth improvement over 4? I feel like there was a ton of misinformation when it came out, and I may have fallen for it, but that was the impression I got from back then. As for what I meant about audio, it's the fact that you cannot use stereo audio and the microphone at the same time on most (if not all) headsets; when you use the microphone, as in a call, headsets switch to super low bitrate mono audio which is fine on a phone call, but when you use something with higher quality like Discord or have anything playing in the background you immediately notice how dreadful it sounds.
There was indeed lots of misinformation. A big source of that misinformation was MKBHD. Please watch these two videos of mine that should help: th-cam.com/video/T-CPobBQi6E/w-d-xo.html and th-cam.com/video/756lbLk3Aqw/w-d-xo.html
THIS! I want to use my headphones connected to computer. There is no way to get good quality audio and mic at the same time. AptX-HD or AptX LowLatency to view movie or game works with a special AptX dongle but does not work together with mic. Apple use their W1 chip. BT alliance should create a new high quality communication standard over with focus on latency and quality, the bandwidth supports it.
@@GaryExplains Able to ask the BT developers if BT5 (LE or not) to support communication with high bitrate and low latency? Combine AptX LowLatency and voice at around 160kbit. Right now when you activate mic it returns to bad quality audio and AVRCP. Some manufacturers (Apple) have implemented their own solution for this.
Something you didn't mention, and the thing that kills Bluetooth audio for me so far as watching videos, is the latency. With a traditional headphone socket, the sound comes out in sync with what you see. With Bluetooth it's late.
Yes, I can see the confusion. Those two numbers aren't directly comparable. The basic physical layer throughout for Bluetooth Classic is 3Mb/s. Bluetooth LE is MUCH slower and doesn't have the capacity to handle the SBC Bluetooth codec.
@@GaryExplains Gary, my BT headphones sound quite different when using BT vs wired. The bass and nuances seem to suppress. Since, the BT life is being forced upon us ( I have OP7), I just expect the audio quality of wired and wireless to exactly match, considering quite some time has passed by since the audio jack removal move. Also, latency doesn't seem to improve either, which means everytime I wish to play a game, I need to pull out a stupid dongle and also the charging process of my phone cease to exist. Whatever you said belonged to BT LE and considering our phones don't use it while transmitting audio as you vividly said, I don't see much improvement. I am not any tech critic. I just want tech to evolve at suitable pace which unfortunately often lags due to the bold moves of some companies. That is all.
So I don't really understand what you are looking for. This is about BLE Audio. The new LC3 codec is better than SBC, i.e. there is an audio quality improvement. If you are looking for better Bluetooth Classic quality then look at aptX and LDAC.
@@GaryExplains I just want BT to develop so that it exactly matches the wired quality in terms of sound quality and latency. Nothing else. It pisses me that companies are forcing upon us unfinished tech. I admire your work. I really don't understand why you are not able to get what I want to say.
Can you pls help me with this doubt pls help me understand better If I use a Bluetooth 5.0 phone like most of us and use a Bluetooth 5.3 audio device like a TWS headset Will I be able to stream audio individually to both ear pieces ? Like listening to music on one and taking a call on the other I know it’s a stupid question but I just want better understanding Will I be able to find my Bluetooth 5.3 TWS device using my Bluetooth 5.0 phone if I lost my headset? As finding perceive location was added only in Bluetooth 5.2 and 5.3 only But still in this case the lost device is Bluetooth 5.3 and the device being used to find it is 5.0
Why can I not find any Bluetooth 5.2 Transmitters or Receivers for sale? I know that the chips have been available for a while now, does anyone know where I can get a BT 5.2 Transmitter or receiver?
You are comparing to completely different kinds of codecs. One is for storing data, one is for transferring it. When transferring data, especially via a wireless connection, you will always have data loss or incorrect received bits. The codec, in this case LC3, has to compensate for that through error correction. When compressing a file, like when using MP3, you don't have these problems because every bit gets saved the way it is intended to be respectively the medium (HDD, SSD) having it's own error correction.
@@soberhippie To be honest I don't know. When having a second thought about this you might be right. Maybe the Bluetooth codecs are better optimized for real time en/decoding for lower latency...
Hey Gary, could this technology be used to make headsets capable of simultaneously receiving audio in A2DP-like quality and broadcasting your voice from the microphone? Currently, you have to choose between turning the microphone in your BT headset into dead weight (using a2dp) AND switching to HSP and making the audio sound horrible.
My amazon fire hd 10 (2019) I see it uses bluetooth 4.2LE so would I still be able to pair to something like an mpow streambot which is advertising having bluetooth 5.0?
So Aka... Don't expect the new Galaxy S20 (S11) or any Snapdragon powered phone in 2020 to support this LE standard, as the Snapdragon 865 supports the current Bluetooth 5.1 right now. We will have to wait until 2021 for the 875.
Since aptX HD has a higher bitrate than SBC then there is little chance it will work on BLE. BLE is slower than classic, so the codec needs to operate at lower bit rates while increasing the quality, that is what LC3 aims to do.
@@alepharcane99 Hmm, no it was some type of audio advancements. There was a speaker bar and other speakers that were being tested at a conference/convention.
I mentioned the possibility of a new audio standard for Bluetooth when I looked at the Mediatek Dimensity 1000 because MediaTek had a slide that mentioned "BLE Audio".
I also had a video from CES 2019 about MPEG-H. It also includes the broadcast ideas. But I had to remove the video as there was some content in it that the interviewer (and the company he worked for) felt a bit nervous about.
Not comparable. One is for high fidelity listening, the other is for low latency everyday audio streaming. The quality will still be better than SBC and AAC, but nothing that will threaten LDAC on the pure audio quality side of things. Latency will be really low though.
Very informative, considering what a patchwork of codecs Bluetooth, it's hard to keep track. I wouldn't mind having a more capable codec than SBC. Wasn't SBC the codec that could go down to 32kb/s if the connection is bad, knowing that kinda always put me off buying Bluetooth headphones, and the price... So in three years I'll need to look for Bluetooth 5.2 devices, noted!
*Bluetooth audio involves too many compromises to compete with high bandwidth audio. Bluetooth is adequate for consumers but highly inadequate for serious audio applications.*
Does anyone know of a headphone that has the music files in them? eg in an internal sd card or its own flash memory. I think this would be an advantage over wireless streaming in terms of quality and battery life. You could always have a wireless controller for play, pause, forward, backwards and track metadata etc.
TheFreezeChill, yes that would be better than Bluetooth headphones. Just wondering if any manufacturer has already done this in a non-diy and smarter way. Flash memory is cheap and the size of the MP3 players is suitably small for incorporation in a headphone.
Eh? It is supported by Android 13 and Windows 11. The Pixel range has supported it since the Pixel 7 and there are many headphones/earbuds that support it.
Being able to broadcast to multiple devices is a really nice feature, I've had a few situations where that had been quite useful. Qualitiywise SBC isn't the comparison anymore, aptX and LDAC can deliver far higher bandwith (but are proprietary, I know...). I haven't experienced that much of a increase in battery usage when using my headphones via LDAC but it's still neat that a better codec gets implemented into Bluetooth itself.
@@RealLifeTech187 My Pixel doesn't have such a setting, but that's no surprise since Google doesn't implement proprietary features. They don't use Qualcomm Quick Carge or analog audio via USB C either.
@@TheFreezeChill They use USB-PD and want it as the single charging standard for android which would make great sense since quick charge (Qualcomm) + Fast Charge (Samsung) are almost identical to USB-PD by now. The not compatible is only VOOC (BBK electronics) But yeah if Google would properly add features then there wouldn't be so many custom UIs and they could solve fragmentation.
@@mikediezel0923 Since there are no LC3 implementations to tests this is just pure guessing, but in terms of overall quality I guess LDAC is better, but in terms of quality at lower bitrates then LC3 is better. Also, at the moment, LDAC doesn't work over BLE.
I didn't know that SBC was around 345Kbps and LC3 will in theory be around the same when received. So, not that I can defintively hear higher fidelity from FLACs and simialar, I just like to, bluetooth is limted in its bandwidth/codec and pointless listening to anything higher. Guess I'll just stick to my wired headphones.
I think the state of Bluetooth is rather deplorable. While we may see this new version in 3 years it will probably take about 6 years until we see it in more budget friendly phones and headphones. Aside from that there seems no indication that this will fix the latency issue that plagues Bluetooth. Even the AirPods Pro which are considered best in class still have 150 ms, which makes Bluetooth unpractical for videos and games.
@@GaryExplains intel be200, a bluetooth 5.4 le audio compatible ™️ Its le audio still doesn't work My bluetooth 5.3 headset i just bought doesn't have le audio, because its protocols are opcional even though 2 on-ear headphones from the same company have le audio My android 14 phone does not have le audio, its locked or the 5 .2 phone doesn't have the optional hardware.
I don't have any LE hardware either, but that is because I haven't bought any. I don't have a hammer action drill (power tool) either, but that doesn't make hammer action power tools are useless, it just means I don't have one. If you want LE support buy a device that has it.
Cheap Bluetooth audio playback devices are unlikely to use this. Ogg Vorbis is totally free without royalties and outperforms MP3 with 64kbit being barely distinguishable from CD quality sound. Why not use that.
If you mean 64kbps Ogg Vorbis, it is very distinguishable from CD quality...unless you you have cloth ears. The free tier of Spotify uses 160kps and that sounds like trash
@@skatcat743 Absolutely not. Bluetooth 5 only added to the BLE part of the specification and has nothing to do with audio as audio is over Bluetooth Classic
Only thing i care is gaiming and i didint hear anything about letency, curent bt is literaly shit for gaiming, letency is terible, how does le audio help? Or we still have to wait for new bt version?
Not really helping the quality. SBC codec was on the bottom of the barrel, both AAC and aptx are a lot better, and more exteme audiophiles will go with Sony’s LDAC codec. This is like replacing the crappiest canned food in your pantry with some better canned food. Still, even regular freshly made food still beats canned food, let alone better restaurant-quality food. Almost every single Bluetooth earphone shipping nowadays has more than 1 codec, SBC is only reserved for backup, your devices always choice better codecs, so most people are actually using AAC or aptx.
My mini PC (HP) had no Bluetooth. Very easy to get one with USB A interface and-voila Bluetooth! I watched a TH-cam video after searching for my Bluetooth speaker. But after a tiny pause i tried another TH-cam video-NO SOUND! "To save current, Bluetooth 4 shuts Bluetooth down when it is not needed"! What a downgrade!!!

My amazon fire hd 10 (2019) I see it uses bluetooth 4.2LE so would I still be able to pair to something like an mpow streambot which is advertising having bluetooth 5.0?
Does this have anything to do with the Developer Options in android 10? I remember seeing some option for bluetooth SBC Codec
So Aka... Don't expect the new Galaxy S20 (S11) or any Snapdragon powered phone in 2020 to support this LE standard, as the Snapdragon 865 supports the current Bluetooth 5.1 right now. We will have to wait until 2021 for the 875.
the best is vorbis 500 kbps but they don't want to implement it inside the bluetooth!
This is to impact current aptx hd devices?
Impact in what way?
@@GaryExplains i want to ask aptx hd will be available through LE AUDIO or it is going to be classic Bluetooth...
Since aptX HD has a higher bitrate than SBC then there is little chance it will work on BLE. BLE is slower than classic, so the codec needs to operate at lower bit rates while increasing the quality, that is what LC3 aims to do.
@@GaryExplains thanks
Why does this sound familiar? Did you do an interview with someone about something like this a year or so ago?
You may remember the video explaining Bluetooth 5.0
@@alepharcane99 Hmm, no it was some type of audio advancements. There was a speaker bar and other speakers that were being tested at a conference/convention.
@@alepharcane99 *MUBALLIG DALVI!* *HAPPY NEW YEAR FELLOW CLASSMATE!*
I mentioned the possibility of a new audio standard for Bluetooth when I looked at the Mediatek Dimensity 1000 because MediaTek had a slide that mentioned "BLE Audio".
I also had a video from CES 2019 about MPEG-H. It also includes the broadcast ideas. But I had to remove the video as there was some content in it that the interviewer (and the company he worked for) felt a bit nervous about.
How does it conpare to Sony’s LDAC? 🙂
Not comparable. One is for high fidelity listening, the other is for low latency everyday audio streaming. The quality will still be better than SBC and AAC, but nothing that will threaten LDAC on the pure audio quality side of things. Latency will be really low though.
Very informative, considering what a patchwork of codecs Bluetooth, it's hard to keep track.
I wouldn't mind having a more capable codec than SBC. Wasn't SBC the codec that could go down to 32kb/s if the connection is bad, knowing that kinda always put me off buying Bluetooth headphones, and the price... So in three years I'll need to look for Bluetooth 5.2 devices, noted!
Headphones using Snapdragon Sound and Aptx adaptive technology can reach max bitrate 860KBPS, is it true?
What a thumbnail!
The thumbnail is hillarious lol
Gary, I liked that thumbnail hahahahahaha!
Question, if its a codec, can't it be implemented on a current devices with bt5 with a software update?
No, because it is more than just a codec.
*Bluetooth audio involves too many compromises to compete with high bandwidth audio. Bluetooth is adequate for consumers but highly inadequate for serious audio applications.*
Does anyone know of a headphone that has the music files in them? eg in an internal sd card or its own flash memory. I think this would be an advantage over wireless streaming in terms of quality and battery life. You could always have a wireless controller for play, pause, forward, backwards and track metadata etc.
You could strap an old MP3 Player to some headphones xD
TheFreezeChill, yes that would be better than Bluetooth headphones. Just wondering if any manufacturer has already done this in a non-diy and smarter way. Flash memory is cheap and the size of the MP3 players is suitably small for incorporation in a headphone.
Its a matter of time where A2DP and the classic protocols will be replaced with LE audio.
Hi from future. Still no LC3
Eh? It is supported by Android 13 and Windows 11. The Pixel range has supported it since the Pixel 7 and there are many headphones/earbuds that support it.
Being able to broadcast to multiple devices is a really nice feature, I've had a few situations where that had been quite useful.
Qualitiywise SBC isn't the comparison anymore, aptX and LDAC can deliver far higher bandwith (but are proprietary, I know...). I haven't experienced that much of a increase in battery usage when using my headphones via LDAC but it's still neat that a better codec gets implemented into Bluetooth itself.
Already possible with BT5.0. Samsung phones have "dual audio" in the settings but don't know about others.
@@RealLifeTech187 My Pixel doesn't have such a setting, but that's no surprise since Google doesn't implement proprietary features. They don't use Qualcomm Quick Carge or analog audio via USB C either.
@@TheFreezeChill They use USB-PD and want it as the single charging standard for android which would make great sense since quick charge (Qualcomm) + Fast Charge (Samsung) are almost identical to USB-PD by now. The not compatible is only VOOC (BBK electronics)
But yeah if Google would properly add features then there wouldn't be so many custom UIs and they could solve fragmentation.
nice thumbnail
Which is better LC3 or LDAC?
LDAC, by far
We've yet to find out. It's probably going to be LC3 which combines the benefits of previous versions.
Depends how you define "better". Better quality? Better fidelity? Better compression? Better at lower bitrates? Better power efficiency? Better what?
@@GaryExplains better in terms of sound quality or bitrate
@@mikediezel0923 Since there are no LC3 implementations to tests this is just pure guessing, but in terms of overall quality I guess LDAC is better, but in terms of quality at lower bitrates then LC3 is better. Also, at the moment, LDAC doesn't work over BLE.
I didn't know that SBC was around 345Kbps and LC3 will in theory be around the same when received. So, not that I can defintively hear higher fidelity from FLACs and simialar, I just like to, bluetooth is limted in its bandwidth/codec and pointless listening to anything higher. Guess I'll just stick to my wired headphones.
I think the state of Bluetooth is rather deplorable.
While we may see this new version in 3 years it will probably take about 6 years until we see it in more budget friendly phones and headphones.
Aside from that there seems no indication that this will fix the latency issue that plagues Bluetooth.
Even the AirPods Pro which are considered best in class still have 150 ms, which makes Bluetooth unpractical for videos and games.
Are you related to Ben Sims
Not that I know of.
@@GaryExplains Ok you look like you could be brothers 😁

...* sigh *
What do you mean by *sigh* ??? LC3 is now in real devices and supported by Android.
@@GaryExplains intel be200, a bluetooth 5.4 le audio compatible ™️
Its le audio still doesn't work
My bluetooth 5.3 headset i just bought doesn't have le audio, because its protocols are opcional even though 2 on-ear headphones from the same company have le audio
My android 14 phone does not have le audio, its locked or the 5
.2 phone doesn't have the optional hardware.
I don't have any LE hardware either, but that is because I haven't bought any. I don't have a hammer action drill (power tool) either, but that doesn't make hammer action power tools are useless, it just means I don't have one. If you want LE support buy a device that has it.
Liked👍
Cheap Bluetooth audio playback devices are unlikely to use this. Ogg Vorbis is totally free without royalties and outperforms MP3 with 64kbit being barely distinguishable from CD quality sound. Why not use that.
If you mean 64kbps Ogg Vorbis, it is very distinguishable from CD quality...unless you you have cloth ears. The free tier of Spotify uses 160kps and that sounds like trash
Multiple Bluetooth connection is already available on Samsung Phones...
Yes, but it isn't a standard, it is a proprietary solution from Samsung.
@@GaryExplains thought it was part of bluetooth 5? Which samsung has been shipping in phone already.
@@skatcat743 Absolutely not. Bluetooth 5 only added to the BLE part of the specification and has nothing to do with audio as audio is over Bluetooth Classic
I thought LC3 was a WWE wrestler 😂

Only thing i care is gaiming and i didint hear anything about letency, curent bt is literaly shit for gaiming, letency is terible, how does le audio help? Or we still have to wait for new bt version?
I hope Samsung include it in the Next Samsung Galaxy S21.
Or we could just....send the audio without transcoding. Bluetooth is so messed up.
Did you not watch the video? If you don't use a codec it will kill the battery plus there isn't enough bandwidth in everyday scenarios.
is this 'pied piper' algorithm?
Is not good old radio simpler and energy efficient
Not really helping the quality. SBC codec was on the bottom of the barrel, both AAC and aptx are a lot better, and more exteme audiophiles will go with Sony’s LDAC codec. This is like replacing the crappiest canned food in your pantry with some better canned food. Still, even regular freshly made food still beats canned food, let alone better restaurant-quality food. Almost every single Bluetooth earphone shipping nowadays has more than 1 codec, SBC is only reserved for backup, your devices always choice better codecs, so most people are actually using AAC or aptx.
My mini PC (HP) had no Bluetooth. Very easy to get one with USB A interface and-voila Bluetooth! I watched a TH-cam video after searching for my Bluetooth speaker. But after a tiny pause i tried another TH-cam video-NO SOUND! "To save current, Bluetooth 4 shuts Bluetooth down when it is not needed"! What a downgrade!!!
Watch apple not adopt it.
"bluetooth broadcast" Lol. To me that's basically renaming FM radio.
Not really.
First Dislike
