SOLEMEMO Myvision N16 Bluetooth Speaker with Dual Drivers, Touch-Sensitive Controls, and Stereo Bass sound for Cell Phone, PC, Laptop, Tablet, MP3 / MP4 Media Player, PSP, etc.
Decent sound for the money. Had it a weeks and no problems.  Edit: I've had this for about a year now and it's still going strong. I think it sounds better than most other speaker units I've heard from friends. It has a nice full sound with decent bass. I use it at least once a week on a 3 hour ride, for listening to podcasts. And then I take it out in the kayak for listening to music. I'm very well pleased with the speaker.
