Summary: These headphones are not the Crushers but they work very well. If you want a decent set of wireless headphones they are good. Have decent bass and a little muffled treble but over all great for the price. I use the Crushers as my comparison and compared to the crushers they are sub par.
Pros: Bought for my girlfriend sister. she wanted a set of headphones. eventually bought her these she says she loves them already she listens to alot of music so I figured I would buy her a good quality headphones to listen to her music to make it sound better.
Summary: Great headset and very comfortable. I even fall asleep in them occasionally! They are surprisingly durable for a plastic headset (especially since they are slung around in a backpack 5 days a week).
