For BTR5 you need a source like a mobile phone. M6 is very good for the money. There are other options like Hidizs AP80 or Hiby R3 Pro or Shanling M2x, you can't go wrong with anyone one of these.

Thank YOU. That helps me much more. Here in Israel I can only get FIIO M6 or M9, it costs 35% more here but Amazon does not ship FIIO to Israel for Bluetooth sennheiser True Wireless IEMs I guess its worth it to buy the FIIO M9, it seems to have a better audio and better build by far to last years. Thank You again.

Hi, Im planning to get either the Fiio M6 o the M9. The main use would be use it as usb dac to stream via bluetooth to my headphones, some of them bluetooth and others via the Btr5. I guess that I would be fine with the M6 since the btr5 should be able to amplify and my headphones are not very high impedance ( hifiman Deva, Verum One, Audio Technica M50X, Sony Wh 1000 xm3, Philips SHP 9500 amongs others... ) .
Thanks in advance.
