**FAIR REVIEW FOR THOSE WHO ARE CONSIDERING PURCHASING**
FYI -- I'm writing this in simple terms and not using audiophile catch words that many use.
K7XX has some strong things going for it, but also some downsides that need to be understood. Please recognize that many people feel strongly about their preferred headphones and do not like any negative comments. Experience with multiple sets of headphones should be required before putting in a comprehensive review. I have borrowed the formatting that other reviewers have used for comparison purposes!
Review is based off listening with no amp, SMSL AD18 and THX AAC 789.
Review is based off other similar price range headphones.
Bass - 5/10
The bass feels underwhelming on this headphone. It doesn't mesh with the music very well. The very low end is good, but as the bass approaches the midrange it seems vacant. The best way I can explain it is that on certain songs it feels detached from the music. It is EXCELLENT for gaming however, and if using for that purpose, this is definitely good for that.
Mids - 7/10
Mids are good in the upper mid, average everywhere else. Nothing exciting or bad, just solid.
Treble - 8/10
Unlike other reviewers I like the treble on this set of cans and it can be a bit bright, but I've not found it to be overwhelming. If you like your highs and clear treble this is a good headphone for you in this price range.
Soundstage - 9/10
The soundstage is very good for headphones. I agree with other reviewers that it's slightly forward heavy, but I've not been unhappy with that. The soundstage again is EXCELLENT for gaming and this headphone shines in games with open areas and quality sound development.
Build – 8/10
The build materials will be a turn off when you first get them. It feels like cheap plastic, but the weight is very light and after prolonged use the have held up very well. Despite the initial reaction, I would not be concerned with the build at all.
Comfort – 9/10
The K7XX is extremely comfortable and can be worn for long periods of time. I found the pads a bit stiff at first, but very soft to the touch. It's a memory foam that is firm and as I've worn them more, they have conformed to my head and went from very comfortable to insanely comfortable. It's one of only a few headphones I've worn in my life that when I take them off I feel like they belong on my head and it takes a little bit before I get used to not having them on again.
Value - 7.5/10 for Music 9/10 for Gaming
The truth is that if you want a fantastic gaming headphone that beats the hell out of Astro and all the other "gaming" headphones out there, this is the best headphone in the price range for gaming bar none. For music, there are cheaper headphones that do music better in my opinion. I do not think anyone buying this will be disappointed unless they are comparing to the 4-5 sets out there which are a better value. If you are considering this versus the HD6XX, buy the 6XX or the HE4XX for music and AKG K7XX if you want a gaming headphone.
For those who value real life...I use the AKG K7XX for gaming and the 6XX for music. I also have kept TakStar Pro 82's which are a fantastic budget option. I also have a pair of Studio CB-1 and Bose QC35 (for airplanes/travel). Every other headphone I've tried over the years has been sold.
Hope this helps someone out!
