HS70 Bluetooth: Max. Volume with Bluetooth way too low

[Eumel]

Hi,

 

I can proudly report that I got the HS70 Bluetooth headhones today. Pretty good when thinking about the price and a truly clear microphone.

 

But, you are guessing right, there is one thing that is a huge drawback for me. When connecting the headhone to my Android smartphone via bluetooth, the maximum volume is just too low. Compared with two other bluetooth head-/earhones, it is roughly around only 2/3 loud when turning to maximum. One of the compared headhones uses Qualcom aptx the other one APTx-HD. But even when I set all three headhones to SBC the effect remains.

 

Would it be possible to launch a new firmware that takes a bit more juice from the battery to increase the max. volume? Or is there even another way (but please no pre-amp apps on the mobile).

 

Would be glad, if you have an idea.

 

Thanks

Eumel

 

PS: When connecting the HS 70 BT to my PC via USB, I can increase the volume really loud, which is then even for me too loud (and I can take a lot :biggrin:). So it tells me, the earphone can do.

PPS: Forgot to mention that my smartphone uses Bluetooth 5.1.
