Very good quality in general
Good quality earphones and case, very comfortable, even if I don't really like this basic earphone format, you can hardly feel them in your ear (I managed to sleep with them and that's a first).
The apparaige works really well even when switching between my phone and my tablet every day - the app is well done in that respect.
The app allows you to change the touch controls and EQ which is pretty handy, the basic EQ profile is good if you're listening to lots of different styles of music, generally the sound quality is good even if sometimes I'd like to be able to turn the volume up even higher to really pierce my eardrums.
Good battery life too, I listen to music for at least 4 hours a day and 1 charge is more than enough for 1 week, even on my long days.
I'd recommend them if you can get a bit of a discount.
