I bought them primarily for the pause button and also I need mic input for some apps I have (guitar tuner for one, voip sip for another, I also have the free "I talk" app.)
I had to switch out the medium ear bud size for the small ones.
They work really well, in case anyone is thinking of buying some.
Can't comment on the bass as I don't listen to music but they do everything else as advertised.
The cord is a rubbery type texture. The mic/button is located right at mouth level with the ear buds in.
The pause switch is a God send. No more opening my folder case to start/stop the book I'm listening to.
A test of the "iTalk" app (free) works brilliantly with the mic.
So, I'm happy and can recommend them with the reminder that I'm not a music listener.
