Brand new, unopened. Non-smoking home.
These headphones are MFi (made for iOS devices), colour is black, 3.5 mm jack.
Listen to music, make phone calls, unit folds for packing, cord is replaceable. A nice step up from a basic pair of headphones.
The package was given to me by Sennheiser as a warranty replacement (I can pass along the delivery note to you as a proof of purchase). In the meantime, I have obtained other headphones for my own personal use and can pass these along to someone else who can enjoy them.
