The MX W1 is Sennheiser’s first
portable and completely wireless stereo earphone system. Featuring two
separate (left/right) earphones, transmitter and carrying case with
integrated charger, the MX W1 offers an uncompressed digital wireless
connection and delivers excellent high-fidelity stereo sound, letting
you enjoy your favourite music without the hassles of cords.
The
transmitter offers the possibility to transmit up to two pairs of MX
W1, enabling two people to listen to the same audio player at the same
time. The system’s carrying case doubles as a charging station for
quick-charging the earphones up to three times while ‘on the move’ —
even without access to a power supply system.
