The unusual capability, though, is the great battery life and good reception using AirPlay.

The battery life is impressive, and after a full charge I can play music via bluetooth or airplay for hours on end

It's aesthetically nice to have in the room, extremely portable, the battery life is strong, and most importantly the sound ROCKS

Amazing sound, great battery life (perfect for when you lose the charger in a sea of boxes), and a great way to stream music/radio

Battery life seem pretty good also--so far.

I like these speakers a lot, the sound quality is amazing and the battery life is great

For us the battery life is amazing, probably because we only use it for 20 minutes or so at a time.

I rely on the app to change my volume.- Battery life is OUTSTANDING

I didn't like any of the options that were the standard brand options, poor battery life if they were wireless or just not a good sound balance when hardwired and then the issue of needing more than one speaker to fill the room

Very good sound, fun shape, good battery life

Battery life is very good.

Battery life is good, just not that sold on sound quality, not sure it's worth the extra money

Battery life is great, control interface is clean and sleek and intuitive!

The sound quality is a little better than the B+W A5, but not quite as good as the B+W A7 -- in other words, it sounds really good.
