I've been using this bluetooth cable with my PM4 for mobile listening. Far from perfect, but a great value at $9. I bought two and just switch between them to charge.

Ive used it, it provides OK to good sound quality on the PM4, sounds congested at some times,
But all you have to do is watch the following video to ruin your day
It has a 400ms lag,
The CSR8645 based has under 50ms lag and is unnoticable.
