Honestly - bang for the buck is good and the built in bass is a nice touch - no huge box sitting on the floor under my desk anymore...bluetooth works just fine - my CPU and phone both recognized the device right away

Overall I'm very pleased with the design, build quality, touch controls, and the ease of pairing and switching devices

The motion sensitive controls are a cool upscale touch

I'm sure you can pay a lot more and get better sound, but these work well enough for me, and still sound way better than the cheap-o PC speakers they replaced.
