Review on Sony SRS-XB23 EXTRA BASS Wireless Portable Speaker IP67 Waterproof BLUETOOTH 12 Hour Battery And Built In Mic For Phone Calls Accessories & Supplies for Cell Phone Accessories by Adam Davidson

Build quality is excellent. The Bluetooth connection is fast and precise. Battery life isn't bad either. So why two stars in the rating? Because the sound quality is terrible. Very lifeless and mute. It feels like I'm listening to speakers that have a thick disk covering the drivers. I sent them back because I just couldn't stand the sound quality. Listening for more than a few minutes was starting to drive me crazy because they sound so bad. Don't buy them and settle for a more expensive pair. If you have them, they end up in a closet somewhere and are a waste of money. They're only good for listening to the news or maybe a talk show. Even playing ball, but when it comes to listening to music, forget it.
