Half the shelves ripped upon assembly - despite following the moronic directions to the T - so I had to fix them myself. Genuine Sennheiser cable in factory packaging. *The headset only sits on the charging stand in a certain direction, but it typically fits right in without a struggle. The sleeves fit well, and the shoulder area seemed to provide posture support (the main reason I bought this item was for posture support). i can?t use them interchangeably. The only apparent metal is the wire to adjust them. The EN is well rounded a fantastic generalist cartridge that can really crank out speed when it needs to. So the watch is on your left arm and main bud is in your eight ear. DommageUpdate: I have been contacted by Digdiy only a few hours after this review. However, this pair was to short in length and rather narrow across the width.
