[quote=Corr][quote=Paulochon]A lost post but very interesting.
Sennheiser PC 150 to 166 are fully compatible. (that's the same design for all of them)
I am searching for someone who have both sennheiser PC 350 & Track Clip Pro (the headphone cost 150� .. a little bit too much if track clip pro isn't compatible :/ ).
Here is what it looks like

From what the image show, it doesn't look like we can attach the track clip pro on it.
Thanks to any reply

I have the exact same model of headphones and you can attach it when you extend the height of the headrest/band part. Works perfectly well for me

I have the Senn 350 headset. It works on the MIC (when in the up position) and on the headband (as previously mentioned.) If you can afford the headset, you won't regret it. It just just get warm when used over a long period of time.
