Review title: nice sound but BAD BATTERY LIFE
Product review: I originally gave this product a 5 star review because the sound was great, plus the size and travel case made it really convenient. Unfortunately, after using it for a few weeks now, I've discovered that the battery life is terrible. I find myself having to recharge it every few days even though I don't use it often!
