Great battery life and very clear sound

great sound, great options, great battery life and waterproof too!

One other thing to note, is the battery is not replaceable on the BRV-

Being that it's water resistant, I would think that Braven had to seal the battery in the device to accomplish this

I love I can link it with a second for stereo, I love I can charge my cell phone (although that does deplete the battery fast) and its one of the most seamless bluetooth linkups I've had - Its a solid speaker phone as well

The BRV-X also had great battery life

The speaker also offers good battery life, and being shock and waterproof is an excellent plus.

Good sound quality, great battery life, syncs with no problem to phone and laptop.

Battery - I work a night shift from 8pm to approximately 6 or 7 am and it will last

Very durable and long battery life!

Sounds great and battery last long

Many other units, including the KMC 1 have a replaceable battery
