Hi there. Sorry for the inconvenience. You can send email to support@tronsmart.com, with your order information and detail description of the product issue, and our customer service team will try their best to help you.
@@TronSmartYTBoverall it's an "OK" earphone for the cost, but there are some inconveniences related to the lack of app to disable touch control, for example. Everytime I open the lid to access the earpieces, they are already responding to touches, so I get multiple unwanted touches even if I try to be extra careful and not grab the touch areas. I also think that this earphone has an overly "closed" sound for my taste, almost like it's inside a can, so much to the point of muffling higher frequencies. As a customer, I believe that at least one extra EQ preset that enhances high freqs. (and I know this implies app support) would make the earphone appeal to all tastes. Just to give examples, similarly cheap earphones like Anker P20i/A20i, and a few Baseus and QCY lowest cost models offer app support, and in Soundfii's R4 this would be a game changer because of the aforementioned issues. Even after the not-so-good experience with this earphone, I continue trusting the brand and I think you guys are great at offering great value products
One thing I forgot to mention is: why do they keep playing even when they are on the charging case (lid open)? I get that this was probably your decision to make them able to connect right after opening lid but to keep playing while inside the case makes no sense
Aah finally I found the way to reset it my sounfil R4 s are not connecting each other now it fixed thanks for this video 😊

How to Control volume?
No option to control volume I guess. The top volume level is itself very low as compared to previous tronsmart earbuds I am using
@@khizersohail2604 thanks for reply.
Yes it hasn't option to control volume.
Yes, it doesn't have option for volume control

I do expected more from this earphone.
Please send us your advice~
