The sound is superb but its not durable
I owned it coz Logitech product can be consider good quality but this earphone has change my perception.

Overall, the sound is good. Better than any earphone i aver had. The design is stylish too. It comes in black color and perfectly matches my psp.The package comes with two ear sponge and two extra sponge.

The problem is its easily broke into two. Seriously. I'm not a rough user and always keep my gadgets in good condition but this one is different. Right now what is holding my earphone into one piece is super glue. Kinda regret buying it.

Pros:-
-High quality sound
-Sleek and stylish design.
-Match with psp black.
-Comfortable on your ears and will not fall down( even if you're running)
-The wire geniusly hide behind the neck makes other person think that its a wireless headphone. Lolz.

Cons:-
-Not durable. Easily break off. The ear sponge provided also easily came off and will soon tear out of its place. No wonder they provide extra set :(
