Bluetooth stereo headphones are the perfect companion to any music fan who wants to listen to music anywhere and anytime. They work well at home, at work, or while travelling. Older versions of Bluetooth stereo headphones do not support cell phone, and hands free communication while newer stereo headphones do support these features. The Cardo S-2 Bluetooth stereo headphones has a fantastic sound quality not easily found in Bluetooth stereo headphones and is surprisingly light. The controls on the Cardo S-2 Bluetooth stereo headphones are very user friendly and I found them easily accessible.
