On rare occasions, some customers can find that their PM-3 headphones may cut in and out on one side, or cut out entirely in one channel.

The most common reason for that is the cable. In new PM-3s, inserting the headphone cable requires slightly more pressure than might seem necessary at first, so it might seem that one channel is not working. If the headphone cable is firmly inserted and the sound is still intermittent or missing in one channel, test with another of the included cables to rule out an issue with the cable.

If the sound in one channel is still intermittent or absent with a new cable, please contact us to organise a repair.
