Yes, I'm on my second. There is a thread elsewhere on Telex v Sennheiser. Incredibly fragile at the earpiece pivot. The pivot structure is simply a solid plastic-type base. Put a bit of pressure on the ear piece at the wrong angle, as if you are pushing them upside down into your briefcase, and you will hear a little plastic snapping sound that costs £370 as the earpiece breaks loose. I cannot believe it was made so light and weak.
I'm on my second because I got one on eBay for £100, plus £50 for the Airbus plug/Boeing adapter.
