It seems that everybody and their grandmother has a single, wireless speaker. On average, most of the speakers have sounds identical; a few are only marginally better than the rest. The biggest difference in my opinion has been how the speaker is packaged.
This one by Oxa is really, really nice. From the beautiful wood casing to the sound it produces, I'm really surprised at how different this speaker sounds.
I play a few samples in the video for you to get a feel of how it translates mp3 files.
Like most of the wireless speakers out there, speaker has a line-in /aux. jack that you can connect to your phone's (or tablet's) headphone port.
This speaker also has an FM transmitter and a phone speaker to answer calls.
The spec's are as follows: + Bluetooth 2.0 + Battery life of about 5 hours + Rechargeable time about 3 hours + Mini usb port/ mini usb plug + 3.5mm line in/ aux. jack--3.5mm plug
This speaker is a beautiful pearlized, bronze-copper. All of the speakers in this series is a pearlized and looks very professional.
It measures 2 ¼" x 2 ¼" x 2 ½" and weighs less than .5 lb.
