The PMX 685i SPORTS neckband headset is not only lightweight but also sits unobtrusively under your biking half helmet.


The PMX 685i SPORTS neckband headset is not only lightweight but also sits unobtrusively under your biking half helmet. It also stays exceptionally secure through rugged off-road terrain and bumps that the woodland trail throws at you. High-output drivers deliver a powerful and natural stereo sound while the in-ear design provides great situational awareness so that you are conscious of the traffic noise when you pedal your way through busy roads and paths. A unique moisture protection system allows you to rinse the headset under the tap to remove grime and perspiration.
