My stepdad used to have a pair of Sennheiser headphones, and on occasion I would listen to them, this was maybe 6 years ago, and I think he'd had them for maybe 3 or 4 years, they were a gift (so I'm guessing the price around then would have been low to mid hundreds), I have absolutely no idea what model (and I can't ask him, he left). Everything I know about them is this:
1) Non-Collapsable
2) Non Bluetooth
3) Non-Swivel (they turn a little, but no more than 45°)
4) they were over ear, they didn't have cups for ears to tuck into.
5) they were blue, probably doesn't help with the model unless they were only made blue?
6) the part that sat on your ears was a felt, there is was absolutely no leather, or leather like material.
7) it had a cable that was at least 2 metres long, and I "think" it was detachable (maybe)
8) they were big'ish, I'm 6"4 and they completely covered my ears with room to spare (if my ears are normal size for my height)
Absolutely any help would be greatly appreciated.
