The Sennheiser MM440-X are the latest generation of wireless Bluetooth headphones expressly designed for travel use and mobile listening. Featuring all the modern iPhone / Pad bells & whistles like built-in microphone and Apple device track/ cue / volume control, the MM400-X can be employed either in wired or wire-free modes as preferred by the listener. Superior 'Apt-X' / A2DP Bluetooth co-dec provides impressive CD-quality sound for streaming music and movies sans wires directly from your tablet and/or smartphone.
