I use the DOSS Asimom. It has a great sound and pairs easily.
I have not tried it but I see a little phone icon and a mic hole.
Its battery can be used to charge other USB devices.
There is a wire to connect to earphone out instead of bluetooth.
It is cylendrical so is not pocket friendly. I do carry it in my jacket pocket though.
Alsthough I did not get mine there, I saw them at Wal Mart.
