It feels cheap and a bit too flexible, but for just over a dollar, I'm not sure what I expected. I'm don't know about in-line pause buttons, but the mic on my headset works through these. The only issue is that the 3.5mm cutout on my iPad case is particularly small, and I actually had to cut off a little more plastic off this (easy with scissors or a razor blade). Once I did that, it worked. The seller I bought from (cellularfactory) also included a cheapo stylus - I wish they'd not bother with useless things like that, and spend the money making the product I actually ordered a little higher quality.
