I use my Android devices to stream music and movies a lot. However, the sound quality directly from a phone or tablet leaves much to be desired, to say the least. For that, you could just wire in some earbuds, but that doesn't help if you're trying to listen to music or watch a flick with other people. In that case, you need an external source of sound. Enter the Logitech Z515 Bluetooth speaker.
I've spent the last couple of weeks using this speaker on a daily basis, and I have to say, I'm quite impressed with what it has to offer for the money.
