checkpointmedia has developed a flexible headphone holder that prevents headphones from emitting sound until removed from the holder. This reliably prevents any distracting noise being heard through headphones that are not currently in use.

?The holder is made of stainless steel and can be adapted to suit any model or make of headphones. As an optional extra, expanded control signals can also be emitted, for example to start a video clip when the headphones are removed.
