Bluetooth headphones with Android 7.1

Hi, guys!
Recently I decided to install Android 7 ROM but have a strange bug with my bluetooth headphones.
It's Bose QC 30. After pairing they with my phone I hear no sound, but if I turn off and then turn on bluetooth on the phone the headphones work correctly. If I turn off and then turn on my headphones and they will connect to my phone, I hear no sound again
If my phone connects to my headphones - all right.
If my headphones connect to my phone - no sound.
When I used Android M, my headphones worked fine.
I tried any ROM with Android N: CM, lineage, Cypher (AOSCP) and many others, each of it has this bug.
I tried to use another headphones (QCY QY12) and very old bluetooth speaker (LG Music Flow P7), they worked correctly.
I don't understand, where is this bug in android N or in Bose firmware.
Any suggestions to fix it? Thanks!
Can I use anything to debug my bluetooth connection and read logs of it?
HTC One M8 (HTC__A07)
S-OFF
Firmware: 6.12.401.4

I would say its from the headphones because are probably old model.I have strange problems with Bluetooth headphones and speakers after upgrading to android 7.My opinion is that they are not compatible with the new version of the android.

The headphones are a new model of September 2016 but they probably use a old bluetooth chip. Although I tried to use lg music flow p7 bluetooth speaker witch is too older than the headpones and it works fine.
It's a very strange issue.

Yes , strange indeed. Sadly I don't think there is fix for that

And I notice the simmilar issue with my laptop (macOS Sierra 10.12.2): at the first time when the headphones connect, they use SBC codec, if I reconnect they then they use AAC codec. May be Android 7 has a bug to work with SBC codec?

Bluetooth Microphone doesn't work

Hey guys,
I've been using my Bluetooth Headphones by TaoTronics (model BH026) to listen to music and it works just fine but I want to make calls and send voice messages through the headphones but it doesn't seem to work.
Current software version: MIUI Global 10.2.9.0
What I tried for now:
Connected the headphones to my laptop and the microphone works there very good. (Can choose the input method manually)
Connected other 3.5mm jack headphones with the adapter to the Mi 9 SE, the microphone on the headphones work automatically.
Unpaired / re-paired the bluetooth device to my smartphone
Cleaned the data / cache of the Bluetooth App on my Mi 9 SE
Made a force stop of the Bluetooth App
Downloaded the App "Lesser AudoSwitch" to force use my BT microphone but it doesnt work.
Any idea why the microphone won't work on my smartphone and might there be a solution for this?
Thank you!

Question Android Auto

Does Android Auto work well on Redmagic 8 PRO? How's the music quality in the car? Maybe someone is using in Ford with Sync3?

No chance to get it working. Skoda Kamique and Kodiaq tells me, not compatible. So only calls via Bluetooth are possible. I'll try to Update the Skoda Software, but i think it is a problem with the phone

I'm using Android Auto with my Red Magic 8 Pro via AAWireless on my Skoda Superb no problems at all. Music quality seems fine to my ear and everything is functioning as it should.

Hey man, I have a redmagic 8 pro matte version and I have used it in my ford with sync3. This is the first android phone that I tried in my car so i don't have anything to compare to though. But I would say that it works well, no issues for me. I used it with waze and my downloaded music with AIMP. I haven't tried it yet with calls/video calls.
I still prefer iOS carplay though for the overall familiarity and smoother interface. I also don't like the big black bar at the bottom while waze is open in android auto, it just eats a lot of space.
