    the best earphones (with earhooks) ever

    Hope Sennheiser will reconsider making this quality higher end product again.


    the vinyl coated metal cabling falls nicely, does not tangle. Quality earhooks you would expect from Sennheiser. The sound is great & the volume control works well. (Looks great as well).


    hard to find, wish Sennheiser would make them again.


    everything - great for gym, cycling & running, as well as just at computer too.


    I would recommend this to a friend.
