Thanks for taking the time to share your interesting and unexpected results. I was checking the comments hoping someone could offer a possible reason for the very poor high frequency performance, along with the other anomalies, but sadly all I found was a troll who just joined TH-cam this month and has nothing of value to add. I appreciate you being honest and saying you don't know instead of acting like you have all the answers. I'm no longer considering purchasing either of these products.
Thank you!
Cheers 🍻
Thanks for your work! Very interesting. I went ahead and bought the B03Pro+ despite your video, mostly out of curiosity and as a way to "upgrade" to LDAC from AptX-HD limitations with another older/cheaper BT TX/RX unit. I listen using a Qudelix-5K, and wanted to be able to have hands free, but with LDAC. Now, the android app for the Qudelix-5K outputs the state of the input, and I was shocked and disappointed to see the following specs used for the LDAC connection from the 1Mii B03Pro+, in transmit mode (toslink output from laptop into 1Mii B03Pro+ with LDAC TX to Qudelix-5K): codec - LDAC, sample rate - 48 kHz, bits per sample - 24-bit, bit rate - 330 Kbps. That's right, while AptX-HD has a bit rate > 500 Kbps, I only get 330 Kbps on LDAC (which is "usually" minimally using > 600 Kbps) and only at 48 kHz (not 96 kHz). So, really no benefit using LDAC on this thing, over AptX-HD, and therefore, no real reason to buy this thing for LDAC usage. EDIT: as I was writing this above, it occurred to me that the sample rate of 48 kHz might be a limitation of the Terratec AureonDual usb toslink output, I switched to the connection to AUX-in from the headphone jack on my laptop, and I do now see a sample rate of 96 kHz BUT the bit rate remains at 330 Kbps. So, as is indicated by Qudelix-5K information, LDAC below 606/660 Kbps is NOT going to yield a sound quality comparable to a wired connection. So basically, the point remains that this unit cannot produce an AptX-HD level of sound quality, even using "LDAC", at least, not in TX mode.
Thanks for the additional data and test results. I did recently test the B03Pro+ with a Monoprice Soundstage3 Portable Bluetooth Speaker, and the frequency response was identical between hardwired and bluetooth SBC codec. I was shocked to see that, but the numbers don't lie. While I must call that speaker a POS for reasons spelled out in the video, it sure does sound good regardless of how you feed it an audio signal. Here is that video link if you're interested:

Very interesting video.... Thanks for this...
I hope it shows what you wanted to know. Cheers 🍻
Excellent review! I really like audio reviews with "numbers". I think those audio reviews with "this sounds bad" or "that sounds amazing" are just useless, becase "bad" or "nice" or whatever, are always very subjective. But numbers don't lie, and I my case your review was very very usefull because I just wanted a better BT adapter (currently I have a very basic SBC one) and I was surprise with the frequency response using aptx HD. I listen Spotify, so for me, aptx HD is more than enough, so I will go with the B06HD+. Thank you!
You took the words right from my mouth 😁. This is why I do reviews, numbers matter, opinions don't. I'll still offer my opinion, but take it with a grain of salt, only the numbers can tell you which side is north. Cheers 🍻
Hiii, my grandpa uses the B03Pro+ to cast his TV audio to 2 pairs of bluetooth headphones, since their hearing is not that good anymore. It works, the only issue is the volume sometimes goes down, and then up again. Like a wave. Do you maybe know what is causing this behavior and how I can stop it? Or do I need to return this thing..
Interesting, that sounds like some sort of bluetooth crosstalk, like another device is controlling volume. The only thing I can think to try is go through the house and turn off all bluetooth devices except whatever is directly connected to the B03Pro+. If that solves the issue then try re-enabling each bluetooth device one at a time until the problem comes back. That will tell you which device is causing the issue.
Otherwise, it could just be a misbehaving feature built into their headphones that needs to be disabled. But that's all I can think of at the moment. Do let me know please what you find, I'm curious. Cheers 🍻
Looking to buy a transmitter. Interesting that on amazon and 1Mii site, they mention ESS SABRE DAC for B03Pro, but for B03Pro+ there's no info on DAC.
I just bought and tried out the 1Mii DS200Pro. I bought it because it supports LDAC (which I'd prefer when listening to HD streaming music). I'm using a Samsung S22 and have LDAC enabled. It paired with no problem and my phone showed it was using LDAC. It sounds great to me so far. I have no others to compare it to and there aren't any reviews of it yet out there. Wondering if you or anyone else out there has tried it and what they though of it.
The pair in the video are the only two TX/RX devices I have that support LDAC. I don't think either one of them sound bad, but I know they sure do measure like total crap.
Cheers 🍻
@@Now-Review-This if that is how you feel I think you should mention this in your video! And if I missed that you mentioned this then you should of made it more clear as the only take away from you video is that the ldac feature sucks

@@Now-Review-This nobody is asking you to bite your tongue but your saying valuable info in comments that your video goes against. That's wrong is all I am saying
@@djhandzhandz8076:
I can't rightfully call either one of these a piece of shit, they're just not. They measure okay with aptx HD. But then they really fall apart with LDAC. I thought I showed this well enough in the video so that all of you can make up your own minds. I gave my opinion on them and a score which I always do, but I will try to be more specific in future videos. The downside of doing that, is more talking 😁.
How is the latency when transmitting? Im trying to see if the bluetooth tech is good enough to use for IEMs (live music)
Good question, I wish I had a number from a test result to offer you. But all I can give is my opinion. If using aptx LL you should be fine aside from half the crowd constantly trying to connect to you, that may cause some glitchy interference, depending on the crowd of coarse. You have many options in this regard, but I would say buy it, try it, and if you have any issues with signal integrity at a normal live event, well send it back for a refund. But if it glitches once, at all anywhere, it's gonna be a potential problem then everywhere. Also keep in mind that bluetooth doesn't have the range of radio or wifi, so distance is more critical using BT.
Cheers 🍻
Hi. Thanks for the honest review. I was just going to buy this Ldac transmitter.
Can you recommend anything for Ldac transmitting purpose?
Please leave the Fiio bta30pro out of it. I just sent it back to the store. What a horrible product that is. I had to pair all my earbuds and earphones I was going to use. My LG tv can memorise them all. :-) Also, it lost connection with its application on my phone, as soon as I turned the transmission mode on. The sound quality was alright in Ldac mode, but it drove me crazy, so I had to let it go. I have three pair of Ldac capable earbuds, and earphones, and I can't use none of them, as they were intended. Sony wf-1000xm4, Sony wf-1000xm5, and the Shure Aonic 50. Can you recommend any Ldac transmitter with optical input, please? Thanks a lot, big time.👍🤙🇬🇧🙂👊
Many newer phones are LDAC capable. My Android tablet is, but I have to go into the developer mode to enable it. Otherwise, I have no experience with any other brand or model so there is nothing I can recommend thus far.
Cheers 🍻
LDAC quality is very much related to transmission rate with the best being 990kbps. On my android phone I have to select this manually as the default is a lower bit rate to prioritise connection stability - at the expense of audio quality. Were you able establish what the transmission rate was? Is this in the documentation for either the transmitter or the receiver?
No, not documented anywhere I have seen. To test would require a spectrum analyzer, and I don't have one.
Good review, Looks like what ever they are doing for volume control is causing a ton of noise.
unless there is noise coming from the power source. I would be curious to listen to it while it's connected the way you did to the pc to see if there is audible noise in the test setup that is not there while using it in the real world. I know my PC causes a ton of noise in audio devices.
The noise is in the devices, not the PC. I show this in the beginning of the measurements with my systems full frequency response. It's almost ruler flat, so any deviation is coming from the devices themselves. I believe the noise on the top end is high frequency jitter. It may not be audible for most, but some will hear it as a smearing of detail in higher frequencies. 1Mii seems to be aware of the issue since they add a 3 stage high frequency filter on some of their higher end products.
Cheers 🍻
I see various info on BT version for this one. Is it 5.0 or 5.3?
I don't know which device you are referring to, but I do not know of any way to verify which BT version a connected device is using, only the host device. So I cannot tell you anymore then the manufacturers specifications.
B03Pro Plus -- BT 5
B06H Plus -- BT 5
Can you review the Emotiva BTR-1?
Sure, if someone wants to send me one I'll test and review it.
8:25 is it actually a headphone jack, or a 3.5mm line out? If it has an integrated headphone amplifier and isnt a true line out, wouldnt it be better to use the rca output? Im pretty sure thr 3.5mm jack is a line out though, makes more sense than having a headphone jack on a bluetooth transceiver, clearly designed with bluetooth headphones in mind.
Also, i assume spdif would bypass this, and would be the ideal format for bypass function. My tv is plugged directly into my DAC with spdif, i intend to plug the tv into the b03pro+ and then plug that into the dac with spdif. This should allow for bypass mode, with the digital signal to the dac being identical to that it receives currently from the tv.
Good question! Only the 1Mii B03Pro+ has a 3.5mm jack, while the 1Mii B06H+ has RCA connections. But the 3.5 output from the B03Pro+ is a headphone out since it has volume control. It can drive a pair of cans quite loud, too loud for me in fact. But I get what you're saying, it would make more sense to have a line out for a speaker, but headphones typically require amplification with volume control so that is how this particular output functions.
In all of the tests results I showed, I was using the B03Pro+ physically connected to the speaker out port from my PC. This was the transmitter stage.
Then using bluetooth to connect from the B03Pro+ to the B06H+. This was the wireless stage.
Then physically connecting the B06H+ to the mic in on my PC. This was the receiver stage
Ultimately forming a loop back connection. I hope that makes sense.
@@roberttaylor3118:
And you are correct regarding the SPDIF connection. There is no volume control with SPDIF and it is the best connection to use where possible or when straight PCM is preferred. However, it is limited to 96khz if that matters at all for your needs.
If I'm understanding you correctly, you want the B03Pro+ to sit between your TV and DAC, presumably to use with bluetooth headphones while still using but not losing any quality from your current setup. Yes, this should be able to do exactly that! However, I have not tested it like that and I do not know if the B03Pro+ can maintain the SPDIF input/output and bluetooth connection simultaneously. It should, I can't think of any reason it wouldn't, but I have not tested it like that. But do please let me know if you run into any problems, I'm curious.
how would these compare to the FiiO BTA30 Pro?
I have no idea, I don't have one to test. It's certainly more expensive, but is it a better product? I couldn't say without one to test.
The only comparable device I can think of is Fiio BTA30 (Pro). I think Fiio might have a bit better competency, as they design much more premium devices, and have better access to good hardware components
Hi man.. i realy need a Bluetooth Transmiter in real LDAC 990kbps where can i get it ?? in a reasonable price..??
Your phone or tablet may be capable of LDAC, for Android you can check in the "developer options". Otherwise, I'd start looking here: amzn.to/3Kyt1Qt
Can anyone help please I'm Looking for something that I Can transmit music to my wireless headphones from my bose soundtouch speaker it has BT and AUX Can it be done with this bit of kit? thanks great video..
Yes, the 1Mii B03Pro+ transmitter can connect to two devices, but will not work simultaneously in LDAC mode. What is the model of your soundtouch speaker? I may be able to provide better info with better info. Cheers 🍻
Bose SoundTouch 30 thanks
@@MaccaNTFC:
That is an input device only. You would need to physically connect your music source to the B03Pro+ for example, then you could transmit your music wirelessly to your headphones and also to the SoundTouch. Make sense? Cheers 🍻
@@Now-Review-This so it can be done if I was to buy The B03Pro plus?? Thanks
Yes! Sorry for the late reply, TH-cam blocked your comment, I just found it and unblocked it! But yes this B03Pro plus Bluetooth device will transmit and will connect to two devices and stream to both of them at the same time. But understand this device will transmit or receive, but not both at the same time. So for example, you would physically plug in a 3.5mm audio cable from your computer to the B03Pro plus, then you can wirelessly transmit to headphones and your Bose system. Whatever your music source, it has to be physically connected to the B03Pro plus, then it can wirelessly transmit from that point forward. Make sense?
Cheers 🍻
Will this work with a Kenwood Kr-v7050 stereo??
These 2 devices will work with anything literally that you can plug either one of them into. But understand, these are 2 separate devices reviewed in the video. 1 is a transmitter/receiver while the other is only a receiver.
Describe what task you are trying to achieve and I can help guide you to the best of the 2 devices for your use case.
@@Now-Review-This much appreciated! I’m looking at the transmitter/receiver so the B03Pro+!
@@slimshadow49 :
the B03Pro+ is the more expensive but also the more capable version of the two. Do you have any specific needs?
@@Now-Review-This not in particular. Have some speakers in the backyard. Just was looking for something with an extended range for bluetooth.
Is it the transmitter or the receiver that has an issue?
I don't know if it's one or both, I only tested them as a pair the way I intended to use them. I don't have any other devices capable of transmitting LDAC, but I too am curious if it's only one device making the noise.
@@Now-Review-This Yeah, I'm planning on using in my car with my phone which has LDAC. I could only assume that it would be an upgrade to the old cheap one I have though.
Я думаю для чистоты эксперимента нужно было в качестве входа/выхода использовать оптические порты, чтобы исключить влияние входных цепей и аналоговых усилителей. Тогда мы увидим АЧХ только радиоканала.
Agreed, but it's not possible since no computer that I have ever seen is equipped with an optical input. There would be no way to create the loop-back without the use of a DAC, which would create a whole new set of potential errors with less reliable data overall. The way I did was the only way I could do it, reliably, repeatably. The noise you see in the video is not coming from any sort of induction from the audio cables, there is nothing in my entire home that operates anywhere near these frequencies. That noise is between the TX/RX and it is very repeatable! Cheers 🍻
I had the unit on the right and ended up sending it back. The LDAC sounded like crap.
are you an EE?
How do you switch codec to AAC?
There is no manual way to do this. Nor would there be any advantage over the other available codes.
@@Now-Review-This Because the Audio Technica M50xbt2 only support low latency mode on AAC. Would be bummer if it didnt detect ACC automatically
@@seaneckhart9914: According to the specs for those cans, they only support LDAC / AAC, SBC codecs. Low latency is an Aptx codec which is not supported by them directly. They require a gimmicky app to supposedly lower the delay which limits the TX source. No matter, there would be no real world difference between AAC and SBC from my test results with other products. In fact, I have a review in the works that only uses SBC and it's every bit as good and identical to the physical 3.5 mil aux cable in frequency response. Literally no difference between wired or wireless on that bt speaker. I have not yet measured the delay, but the frequency response is identical.
Are there any firmware updates for these two devices?
Not that I am aware of, no.
I kind of expected this kind of test to potentially read un-true,
As computers are known for creating audio ground loops caused by electric potential to the ground connection.
Example, peripherals that are hooked up, A low quality PSU, Sudden mouse movement, GPU and CPU fans with thermal switching & even the motherboard itself! It's caused by the different potential between two circuits.
Did you try using an in line ground loop isolator? It may help in your tests
I'm a music producer & use an external audio interface,As never found computer onboard sound/sound cards that did not produce some form of ground loop feedback.
Another thing to try with your BO3Pro+ is doing away with a plug in the wall USBC PSU which can create ground loops & plugging it into a battery power bank.
Run another test & post your results,But again you may still have groundloops.
I do not understand these things do...?? There is a lot extra info but show how it works and what it do for you 😉
that looks alot of interference to me "radio wise"
There could very well be some RF noise. I think it's HF jitter on the top end since it is so consistent and repeatable. But I don't have a spectrum analyzer to prove the source of the noise, at times like these I wish I did. I know 1Mii have added a 3 stage capacitor bank in one of there other models to filter out the top end noise, so they must be aware of the problem. Cheers 🍻
Thanks@@Now-Review-This. Can you specify which device 1Mii added the 3 stage capacitor bank to?
