This is the best.
Azio benütigt a software, CSR Harmony, which is problematic, full of bugs, and end of life, that is, without support.
Azio Customer Care is absolutely Sch ... e. CSR also. So, never.
Avantree was a scam, they write Multipoint and do not write that with Multipoint you lose APTX.
And they write APTX low latency but not for that one needs a low latency headphone.
In addition, the scope is the worst.
These Sennheiser work perfectly.
I would have loved to have more scope.
Perhaps now that Sennheiser makes new BT headset, also this product will improve?
