I got this because I was never able to hear myself while recording drum tracks. The models I used before had a looped cord, like the one shown in the picture, which was a little too short. I finally decided to get my own about a month ago, and it didn't have a looped wire. It had a straight one, which is longer, so thats good.
While tracking with the headphones plugged into the laptop I wasn't able to hear myself properly. I was disappointed, but then i plugged it into the headphone input in my speakers which were connected to the laptop, and the result was fantastic. They're loud enough no matter how hard you play. I bet Dave Grohl would have a hard time hearing himself play if he turned these headphones on all the way up !
Thats why these are a must have for recording drums. Even if you use them to listen to music, no matter how much you turn the music up, no one will be able to tell what you're listening too. If you have issues with volume, then these are great. Cancels outside noise, prevents your music from being audible on the outside, and so on.
Build wise, they're sturdy. They look heavy duty. The ones I've used before have never cracked anywhere. That's good if you use these in a studio, musicians often tend to be pretty careless.
Comfort varies from person to person. Some people can wear these for hours without tiring. Some people can't. My right ear starts hurting after excessive use, but i think it depends on ear size, personal preference, and a lot of other factors. When you put these on, you can feel a vacuum being made. They really do put you in your own audio world.
However, the quality isn't fantastic. The reason i gave it 5 stars is because I didn't buy these for sound quality. All I use these for is to listen to a metronome or a scratch track while tracking drums. The quality is no better than your average headphones. So if you want great sound quality, you might want to look elsewhere. But if volume is your issue, look no further. You simply will not be disappointed.
