The Sennheiser MM 550 is a Wireless Bluetooth Stereo Headphone that features A2DP Bluetooth technology, and is the official travel headphone of the NBA's Dallas Mavericks! This headset allows you to listen to music wired or wirelessly, take call over Bluetooth, and chat with others without removing your headset by using the convenient TalkThrough function. NoiseGard 2.0 cancels out 90% of ambient noise, Selectable SRS sound simulation adds excitement and depth to your audio, and the invisible microphone gives you added convenience.

The replaceable battery of the MM 550 Headphone charges via USB cable or wall adapter, and you can use the included audio cable for a direct connection to your phone when Bluetooth is not available. Advanced DuoFol transducers provide superior detail and frequency response from the hi-fidelity audiophile speakers, and the easy-to-use control panel provides concise "click" feedback. Enjoy a world-class Sennhieser sound experience with the Sennheiser MM 550 Wireless Bluetooth Stereo Headphones!

(Due to the nature of Bluetooth technology, users may experience a slight audio latency when watching video on a portable device. The headphones are working fine. This is a characteristic of all Bluetooth headsets. Latency is not an issue for audio-only use, OR when using the included detachable headphone cable for a wired audio connection when watching video.)

Great flawlessly!

works well with all my phone and ipad.  Tried the wireless Dre beats and these worked much better and sound much better!  I will need to look into replacement ear pads because I wear them to the gym.  Also I can leave my phone at my desk and walk to the end of my building and they still work about 200 feet....woot woot!
