The wireless S10-HD Bluetooth stereo headset is perfect for your active lifestyle. Silicone seals and encased speakers protect components from moisture. Simple controls on the headphones allow you to adjust volume, change tracks, play/pause your music and take calls--music automatically pauses during calls and resumes after the call.

Plus, with up to 8 hours of play time and 9 hours of talk time, the S10-HD will last through all of life's little adventures. It's compatible with most Bluetooth-enabled mobile phones for taking calls, but it requires a mobile phone or digital audio player with an embedded A2DP Bluetooth profile for stereo music streaming. Sweat it Out Optimized for an active lifestyle, the S10-HD uses advanced materials like hydrophobic acoustic mesh in a lightweight, sweat-proof design. The new ear cushion interface protects the speaker from sweat, and silicone seals protect electrical components throughout the headphones. To reduce exposure to moisture, all buttons are co-molded and the micro-USB charging cover is molded to the headphones housing with a waterproof plug. Perfect for your daily workout, outdoor adventure or just when you're out and about, the S10-HD keeps the moisture out and the music flowing. Simple controls on the headphones allow you to adjust volume, change tracks, play/pause your music and take calls. Advanced hydrophobic acoustic mesh keeps out sweat while preserving audio quality.
