I have had these for over a week, and I think it was worth the purchase for my ER3SE. I gave it four stars because I believe the volume control is too high up. I can explain. The microphonic problem always seems to persist for me, especially when I exercise, so I usually have to wrap the cord around my earlobe. However, the volume control then sits almost directly on my earlobe instead of hanging further down, which causes that side of the cord to randomly come off my ear. This is very annoying. Otherwise, the cable sounds great and feels very sturdy. I would recommend for other iPhone users.
