    According to our hardware's date sheet, it should support SBC,MP3 and AAC decoder, however, it seems to receive either SBC or AAC is depends on the transmitter side(players)more than the receiver side(BTC-01),   Hope this link and related information will be helpful for answering your...

Thank you so much for your support and comments.   Regarding the battery duration, we have released a special external battery pack called EXB-01 to help extend the playback time for more then 250 hrs. (http://www.lear-eshop.com/products/lear-exb-01-4600mah-external-battery-pack-for-btc-01)...

Yes, we are.

Thank you so much for your support!

Never mind! But it seems this is different to our A2DC connector, hence, we have no this connector at the moment. Sorry about the disappointment!

It looks like our A2DC version will work, but sorry about that we can't make sure if it is using the same standard. Will be helpful if you can send us some pictures of the inner connector part for checking.

    Thank you so much for your support! We will surely take your words into account and keep improving our products is the near future. Please enjoy and share your thoughts with us!

Totally agree with you! We aren't perfect, so do our products , that's why we are more than happy to help to exchange another unit for you or any of our customers, when the one on your hand seems not working properly or looks like defeated.   Only one thing we would like to emphasize, the...

The output imp of BTC-01 is lower than 0.9 ohm. However, we are not talking about the ability to drive an earphone, but the sensitivity of an earphone to hear the micro details included the background noise or circuit interference. The impedance should take into account but  also the sensitivity .

  The most scientific way to test the product is ,place them at the same distance together at the same time,If you found the connection between the BTC-01 is poor than the BT earphones which you've mentioned, we are more than happy to help to exchange a new one with you,as if talking about the...

  If you can hear the interference with the BT, besides the product is defeated, it is always caused by the low impedance and high sensitivity of the earphone driver.   Just like you plug an earphone to a high power/gain headphone amplifier, the  balanced armature drivers is always more...

  We understand that you feel unhappy with the BTC-01 . However,We would appreciate it if you could provide more information, like apple to apple comparison between the BTC-01 with your "High Quality Receiver" and let us know how poor the BTC-01 connection between the high quality one is, it...

To be fair, it seems the Bluetooth connection /stuttering problems isn't just caused by our BTC-01, but also the transmitter side,which is the phones or players. Please feel free to check this out for the comparison(Same BTC-01 but different transmitters) :     Poor the connectivity ,poor...

Nope~ Just we will have the latest version soon, please stay tuned for the updates.

Surely we will take your words into account and release such a design in the upcoming new products~

  Yes it will work with the UERR, but the connector is not same as the UE's original design,as we are using the flat pin type connector. There is no stiff memory wire around the BTC-01 cable, but it comes with a removable silicone ear hook instead of .

  Our 2pin should work fine with such a recessed socket . However, please kindly note that the latest 2 pin version is replaced by the bended design:
