I just got these headphones a few minutes ago and plugged them into my computer and I can say that these are the best headphones I have ever used! They are light weight and sometimes you might even forget you have them on there so comfortable. I have owned a pair of Skullcandy Smokin' Ear buds that broke and these are way better. There is NO uncomfortable feeling wearing these. Earbuds are a bit picky when it comes to getting good quality and comfort. These however have had the best quality from a headset or ear buds ever! Sound quality is AMAZING!

The bass and treble is EXCELLENTLY mixed. Never before could I hear high trebles in the presence of heavy bass. You hear everything with these.

Buying these is completely worth it!
Forget high cost headphones or earbuds, get these and you will never want to buy any other headphone/earbud set.

These headphones are pretty sweet. The sound quality is great, and they really do look sexy. A few girls actually asked me out just because they thought they looked cool. The only complaint I have is that they hurt my ears a bit after using them for more than 30 minutes straight, but I think that's because I wear my glasses while using them. Just a thought. These have a lifetime warranty though and are super cool. YEEEEEEAAAAAAAAA BOOOOOOOYYYYYYYYIIIIIIIEEEEEE!

This is exactly what I was looking for in headphones. Loud, great sound quality. The bass is a little overpowering but since I mainly use them as computer headphone all I have to do is turn down the bass and they're fine. After all, it is better to have higher bass that you can turn down than lower bass that you can't turn up.

I've owned these for 5 years and they still sound great. Lifetime warranty, crisp sound, good base for portables, sturdy, comfortable. Get them.

I can't improve on what's already been said about these phones. Sound as good as my Grado SR60 at about half the size and cost. Seem to be very well constructed but I've only had them a few days.

Stayed in place on my head through a sweaty 6-mile jog this morning. First time I've had my tunes along on a jog and I highly recommend it.

I run on a busy highway so I wanted to be able to hear outside noises for safety. I could hear the traffic and the music. With no outside noise, the music is just incredible. I use 320kbps mp3 mostly and, although I have a pretty good pc stereo setup (M-AUDIO, Kenwood, Bose), I heard not only new musical nuances but words which I had not previously recognized.

I don't pretend to be an audiophile and my hearing has gone downhill but I've been into music a long time. We're into SACD, DVD-Audio with Klipsch and Polk speakers so I think I've heard some pretty good music. I was still impressed with the clarity and fidelity of these little phones. Oh, I've tried them with both my pc stereo setup and through a Sansa Clip player. Both sound terrific.

They don't look as hip as the little buds but they don't look totally dork either. Cable is plenty long enough for me. Now, I did hear a slight click with each jogging step which I think is just the wire slapping the phones or movement of the ear cup itself. It may begin to bother me and if so I'll try to eliminate it but today it just helped me maintain a steady pace and didn't detract from the music at all.

I think most people will really like these phones. I definitely do.
