An exciting (semi) closed back headphone.
This is a very unique headphone. It was the closed back pair I had been looking for for years. I currently own a few open back planars (He1000se, and Ether 2), and was looking for something closed back, and preferably dynamic. I was looking into the focal stellia for a long time, and was really going for it until the perfect timing these cans had in being released in US. I was looking for something very bass heavy, but easily EQ'd to take some bass away. I was not too keen on the sennheiser hd820 because it seemed to me like a less open hd800s (which is not quite my cup of tea, although does have the best soundstage, and some of the best imaging ever.), and the Ether C Flow was tempting but they were another pair, to me, that was a great open back sounding closed back. which is fine, but between the 2 phones I had, being the most open was not the most important thing to me.
And boy do these headphones live up to every reason I wanted them. They do start off very bass heavy without any eq. Which was exactly what I wanted. I want to be clear, these are the best headphones I have ever listened to for metal, even without any eq, they are just stellar for genres of thick, thumping bass. the dynamics of the thump is so physical it almost seems violent. which is perfect for metal, and dubstep, and edm, and rap and other Bass heavy genres where the most of the atmosphere is made up by bass. Attempting to EQ them, I was blown away.
out of box, these headphones are warm and dark. not for everyone, but for my other pairs, it fit right in. the brilliant thing about these, is that if you take down the bass some, and increase the treble a bit, these quickly became the most detailed closed back headphone I have ever heard, besides the stellia, which is known for detail and dynamics. things appeared in the music I could not hear with my ether 2's. not quite as much detail as the he1000se, but as of this moment I cant name another headphone that does. These headphones were to top off my collection with a closed back, easily eq'd dynamic pair of headphones, and these are exactly that.
There are 2 downsides to this headphone total, which for me is not enough to bring down from 5 stars to 4, but may be for some people. the first is they are pretty dang heavy. they are not uncomfortable per se, but my ether 2's and he1000se are both on an entire other comfort level. the second being it does have a slight disadvantage in soundstage due to being a closed back headphone. as open back as they are, and can be, when there is a full choir singing and no other accompaniment, the sound will bounce around on the inside a little bit, making it hard to make out the details of the choir. If instruments are added, this takes away the excess resonance, however it does exist in tracks involving just a choir. the reason for this being that they really are just closed back headphones, and no matter what, the isolation you benefit from will take away from certain aspects of the sound. and although this does better than every other closed back I've listened to (minus the hd820), it Is an issue with closedback headphones in general, that open headphones will always reign supreme. I needed a closed back pair, so this was not an issue with me.
Overall, this is an incredible set of headphones, albeit for certain tastes. it has VERY FEW weaknesses if you are willing to EQ them, and when you do, they compete with open backs on soundstage, imaging, separation, and clarity. If not, you really would only need these if you enjoy bass heavy music. and as it stands, these are the undisputed kings of metal, which is a resounding win in my book.
