During my time with these cans, I've listened to my entire collection of music, played hundreds of hours of games, and sat with them on for durations of over 8 hours in the heat & cold
Pros: Sound quality. With my setup it's simply amazing. They have clarity, punch, and a consistent sound. Soundstage is adequate though I would like more coming from Grado SR80i's and AD700's. These cans, in the right configuration, will reveal almost every minute detail in lossless, quality recordings. For gaming they will give you accurate positioning with an above-average soundstage, but these are no AD700's.
These cans are extremely comfortable as my ears fit within the earpads. The band is adjustable and the mechanism is nice and sturdy. If I may say so the design is also quite well done. I've worn them for over 8 hours at a time without taking them off too much. They do a good job of blocking all keyboard noise when gaming or listening to music. Noise cancellation is average. High end sound is definitely there but not harsh at a decent volume. The mid range could be a little better, but the frequency response of this headphone is fairly flat. The bass response and amount is substantial but not over the top, other wise it would drown out the other areas. Drum hits and bass guitar is satisfying especially with quality music.
This premium version also comes with a pleather carry case with a foam internal for safe transport.
Cons: Price. These were an expensive purchase for me at $399 AUD, they were cheaper from Amazon ($250) but I didn't want to wait weeks for Christmas shipping from overseas, so I bought locally.
These cans also leak sound like a barrel full of holes leaks water - this may be a con for you. No good for mobile listening, these are very much suitable for at home/man cave usage, if you don't want to piss people off.
Other notes: The cable is located of the left side of the headphone, there is not one from each driver merging into one. Depending on your preference, you may or may not like this. I will say that the dual cables on my SR80i's annoyed me as they would always get twisted. Depending on your tolerances, these cans might also be considered heavy, so take that into consideration.
Final notes: At this price range you are reaching the point of diminishing returns, so choose carefully. This headphone is pretty well-balanced in every area with a few strong and weaker points. It's a "safe" bet for any audiophile looking to listen to a wide range of music, and throw some gaming into the mix.
