2 out of 5 eggsSounds really bad

Pros: They look expensive.

It comes with additional red/white wire adapter for increased compatibility

the wire of the headset itself is very long

Cons: They sound terrible, they really do. Honestly i did not know a cyber acoustic brand headset could sound even sound bad. And i am the complete opposite of an audiophile.. I usually think everything sounds good.. but this is like noticeably bad. It just takes clear sound and makes it sound muffled.. As if you are listening to music playing in another room in your house or something. I even checked to make sure it was plugged in all the way because i could not believe it could possibly sound so bad

Also i saw in the picture there was a knob on the actual earphone itself and i thought it was to control the sound for the entire headset.. But there is actually one knob on each side to control the volume coming out of each ear individually and that really bothers me.. Why would anyone want to go through the trouble of trying to equal out the sound coming through each ear with two different knobs?

Also turning the knobs on each earpiece just feels and looks extremely awkward

Also the earbuds also do not cancel out background sound very well
