Boom Microphone Cable QC35 Replacement Cord for Bose QuietComfort 35 & QuietComfort 35II(QC35II) Headphones, Gaming Mic with Mute Black 120CM/4FT

I had a similar product. It broke after a few months. This item already appears to be of better construction , design, and quality.

This claims to work with the Bose QC35 II, but it does not. It barely fits into the socket, with the connector being strongly pulled to one side. Because of this strong pressure, some of the contacts don't connect, and so the headphones are unaware that there is a cable plugged in. Only one of the speakers plays any sound.

The original one was great but only lasted 2 months and then the mute switch broke in the off position. They sent a replacement and the people on my calls say it sounds like i have a cold (really muffled).

Contrary to the claims of this product, it is not compatible with my wireless Bose headset. The pin connection isn't designed to actually plug in all the way so it just falls out and isn't recognized. Oh well.
