dodocool Hi-Resolution Rechargeable Stereo Wireless Speaker with Built-in Microphone

It was dirt cheap but served me well aside from the grill kept following off even after several super glue repairs.

This is a great speaker that produces rich sound and nice bass.

Sound is fairly loud, clear and decent for for a small portable Bluetooth speaker.

Works well with my android phone and sounds pretty good. Volume works well on the speaker and phone.

Sound is not as crisp as I'd like and the lower end of the spectrum sounds muffled.
