CBK-BQ25 Audio Cable Replacement Cord for Bose QC25 Quiet Comfort 25 Headphone with in-Line Mic and Remote - Black

Works great, tried on both the 25 and the 35 models and had no problems. Non-Bose users, check what your input end is, this cable has two different sizes to be compatible with Bose headphones (the two I’ve listed I can vouch for)

not quite as good as the original microphone, but it does well to pick up my voice.

Works like a charm

I bought this cable less than 1 month ago. It has already stopped working. There is no audio coming out of the right headphone. This is unacceptable.

The sound worked, but the buttons for the volume did not work.

Finally! A cord that fits my Bose headphones!! After ordering 4 different cords from other vendors, this was the first cord that actually fit and works. I could've bit the bullet and just ordered the $30 set from the manufacturer; however, I'm cheap and opted to keep buying $9 cords that didn't fit. Obviously, my logic was off by quite a bit. I've only had them for a week or so and can't speak for their longevity. The volume and on/off controls work just fine, though.

Fixed the problem on my Bose set.

Don't bother. Cheap quality, and doesn't even fit properly.
