Wireless on-ear headphones - microphone does not work

I have bluetooth headphones Sony WI-C310 - headphones are connected automatically and both the sound and the microphone work (profile - A2DP Sink).

I bought JBL T460BT headphones and I’m having problems with them.
After plugging in (profile - A2DP Sink) the microphone does not work (sound works).
If you repeatedly turn the headphones on and off, the laptop may hang up.
While listening to music the sound is interrupted (sounds like slow internet).
