5 out of 5 eggsUpdate on a earlier review

Pros: These headphones improved alot over the course of using them. At first the bass was there not as much. But now the bass has improved alot which was the first thing I notice as it let you know its there and hit hard too.

The headphones bass on these headphones are hard hitting ,while being tight, they are not boomy at all. The headphones works great for Eletronic music including Dubstep,DnB and any other heavy drum and bass music. When you first listen to the headphones you might not think so. But like I mention over the course of using them they will burn in and the bass will be the first thing you notice when it improve. Rather you believe in burn in or not.

The 3D wing design on the headphones could be improved as the headphones does slide off my head some times, but the rubber band trick can fix that. Where you place a rubber band around the 3D wing flaps.

The Ear pads feels good on my ears,But I inside was a tad bigger and used Velvet instead of Pleather.

Over all these are very good headphones for those looking for all arounder's. These are easy to drive headphones so you dont need to use these with a headphone amp, just a good source and i don;t mean onboard audio.

Cons: none major

Other Thoughts: The most important thing you need to know is that this headphone will let you hear the flaws of your music collection if you have low bit rate mp3's as we.. the flaws of your source. if you have onboard audio, then the first thing you should be doing is getting a better source as a better sound card or dac. Before you get the headphones or any good headphones.

You do not want Boomy bassor One note bass is Where the bass is the same boom over and over and over. Or where the bass is muddy.

The bass that you want is the bass where you can hear the different notes of bass all coming thru, without the bass out doing the rest of the sound. Now these headphones will not please a bass head who want nothing but all bass, but it please those who want alot of bass without it taking over the spot light.

4 out of 5 eggsGood for balance

Pros: Spacious around the ears.
Headband is awesome. Allows head to breath
Voice reproduction is great
the mids on this thing are amazing!

Cons: Bass will kill these...
These are not meant for the person who only listens to electronic or rap

Other Thoughts: Bought these with some monster inspirations,beats executives, and AKGs. These are best for someone who has an amplifier. If you are just hooking this into your computer using on board sound..dont waste your money. They will sound like cgarbage and break up/crack/distort. If you have an amp or a decent SoundCard. These things will sing beautifully. The voice reproduction is spot on! Sound reproduction is natural WHICH means the bass is not boosted nor the highs! Too much bass and these will crack and distort easily. These are best suited for Rock and classical, country.with some rap. Obviously they will sound decent with all music, but the aforementioned will be best. Your set up truly does matter with these though.

5 out of 5 eggsPerfection!

Pros: Simply put? These are the best headphones you can buy. I have tried a couple dozen of headphones over the last few years.
Nothing comes close.
Forget Razer, Beats, Skull Candy, Turtle Beach, and anything else you can think of, look no further.
As a gamer, a movie/tv watcher and music listener it gets no better than this.

Cons: Maybe the price but it's a non factor for myself.
It's more than worth it considering the money I have wasted over the years on other brands.

Other Thoughts: Do not bother with these if you are a computer user without a sound card. You might as well save your money because using your motherboard audio with these amazing gems is like owning a new Lamborghini with all the wheels taken off.
These with a good sound card simply gets no better.

5 out of 5 eggsGreat for desktop usage

Pros: The sound quality is really good! The music is clear, and the large ear cups keep the noise outside. The braided cable is long and doesn't get tangled.

These features combined mean I can keep my audio at a lower volume, and still not hear people talking around me, so I'm doing less damage to my ears.

Cons: The headphones are quite large, and definitely not very mobile. The great sound quality means you can tell when the recording isn't that good.

Last, the price is definitely something to keep in mind. The sound quality is better than what you'd get from cheaper headphones, but the quality does not increase linearly with price.

Other Thoughts: The company I work for got these for me. I wouldn't have tried them out myself, due to their high price. I don't think I can go back to my old headphones now, though!
