In-ear headphones I wear personally just do not like, so I tried it with this and have to say: It could not be better for 9 ...!
+ For processing
+ Sound. No noise, no rattle, everything was great (I expect more not at 9)
neutral for the fit, as the earpieces are rigidly realtiv
- For the cable, which you first must be unmount 3-4 days and even for these are the headphones connected to each other
So as I said, to do sports for time 1-2h hours, as well as for jogging ideal. Those things sit and watch, and set up a system with music.
Please do not expect sound performance a la Sennheiser or something in the way ....
