This is my first set of bluetooth speakers, so I can't say that I'm experienced but the sound and quality of these speakers are fantastic! These speakers are really useful in that range is much better than you'd expect. I was outside and I could still connect to the second floor of my house. Imagine my surprise, when I walked in my house and heard the music.I like that I can connect the aux cord and use them as regular speakers too. The sound transmits very well for what I'm using it for.I haven't tested the extent of the battery life yet, as I'm mostly keeping it stationary and charged. But for the 2-3 hours that I've brought it around with me, it seems like the battery will last long enough for me to find a power source. What I'd really like to do is to connect multiple speakers together, either wirelessly or physically and try to get a surround system, but unfortunately, bluetooth only connects to one device at a time.
