Unfortunately, I'm not aware of any, and it's not for lack of trying.

You're lucky - I still have headphones like these. I gave them to my wife once. She used them just once on a flight to Canada. They've just been lying around ever since. I still have a second pair for myself. These things are simply brilliant. I have advertised the headphones here as "second-hand". You are welcome to buy them. Greetings David PS: CHF 20 will go to Galaxus :)

I am not satisfied with these headphones. The noise cancelling works more badly than well. If you switch it off, you get annoying noise. That's why I bought the Mackie MP 320 (without ANC). If I need ANC, I use large on-ear headphones.
