The sound quality is perfect they have really good bass. At the relatively low volumes I usually use for listening to books on tape, the battery charge does tend to last the advertised 5 hours. This product is wonderful. And it does not bother me to use it for long periods of gaming. I could take it with to places that I can secure it around a post. Ive had it for just over 2 months now, and heres my list of Pros and Cons. I needed some weekend shoes, and i found them! These buds were very quality for the price and probably the loudest buds on the market. This flip flop runs SMALL. Love the old school style of this slipper.
