    I purchased this Speaker for my boyfriend because he didn't like the Sony one I got him from walmart. This Megaboom speaker is exactly what he wanted. It connects to his phone very easily and is a lot louder than his old speaker. The battery life last 10x longer than the Sony speaker.

    Love the sound, and the quality of the speaker, only reason not 5 stars is connectivity can be spotty at points even in close distances.

    Hard to get a compact BT speaker to sound great but this is probably one of the better ones I've used. Bass extension could be better but has excellent mids and highs.
