I have for years been resistant to open back headphones. I don't know why, I just have. I finally caved with this purchase as I see more and more folks using them. I didn't know what I've been missing! I have had some great closed back cans - many of the classics, I have a pair of ATH-M50x from AudioTechnica, I have 7506MDRs from Sony, I've a pair of Pioneer DJ headphones which I love, but replacing the damaged ear cup turned out to be outrageously expensive. I have a pair of Bose QC2, and BAR far, these headphones are my favorites now. The sound is warm close, and the open back gives it a natural feel that is just lovely. The bass is smooth, and there's enough clarify in the treble to hear all the detail. Top notch, can't recommend enough. I used them primarily for music production, as a classically trained audio person, I feel like I have a pretty solid ear, maybe not the best, but pretty good. So I think if you're looking for headphones that won't kill you to buy, but have the quality to take your mixing up a level - these are a great buy!

Got these cans for 400 dollars for black Friday.

SOUND:
These headphones sound better to me than the rest of the 600 series simply due to their better sub-bass performance. They have a pretty wide soundstage, have excellent instrument separation and sound good with all music I have thrown at them. The mids perform excellently, just as the rest of the HD600 series, and the treble is sparkly and nimble but not fatiguing. These are a good, balanced, warm sounding pair of headphones that are well worth the price that I bought them for, however I could not recommend these for $600 as this price forces competition with a higher class of headphones.

COMFORT:
These headphones are the most comfortable pair I own, with nice soft earpads and a perfect amount of pressure that gets a good acoustic seal over my ears. My head is on the larger side, so as to the issue of clamping force, I really did not feel that they clamped too tightly. These are the kind of headphones that I could wear comfortably all day and forget I even have them on.

DRIVING EQUIPMENT:
To those that have mentioned an unimpressive performance from these headphones, when used without a headphone amplifier or properly specified piece of equipment, these headphones tend to sound a bit soulless, empty, or a bit muddy. However, the great thing about the HD600 series is that they tend to scale very well with good sound equipment. The difference in sound that an entry level Schiit DAC+Amp stack made was well worth it and really made these phones come to life. This does mean, however, that you should also consider the cost of an amplifier and DAC unit as a cost included with these headphones, so at minimum another $200 added onto the already expensive price. There are many other good options for headphones that are easier to drive and do not require a dedicated amp for this price range, so if this isn't for you, I would look elsewhere.

Overall a great sound albeit a bit overpriced at MSRP.

To start, I would not consider myself an audiophile at all. I do though notice the quality of sound when compared to any of my other headsets. I use headphones for everything so wanted to treat myself to a headset I could use for work without the gamer look while also able to use it for entertainment. I have a pretty simple setup and tried it both with a usb cable directly to pc as well as adding in a pre - amp and DAC. I did notice the pre amp make the biggest impact as in some games it was quiet until using the pre amp. For meetings, youtube, movies and chatting with friends these sound awesome and clear. I have had many "high end " ish gaming headphones as they had the comfort and great sound for games over the years ranging 150-400$ range and these sound the best for non gaming for sure with the exception of action movies with a lot of bass. The bass is good but being open back and less emphasis on over the top booms I prefer is less than my other headsets. Also in shooting games especially you notice you hear much less sound queues and directions like i would with other headsets. TLDR these are amazing and clear for most things i use like movies, conference calls and music BUT don't expect it to be your favorite for gaming especially for sound location based games such as FPS games. I use this daily and just switch to gaming headset for shooters. well worth the purchase .

Have now had several listening sessions. Comfortingly fitting for an hour of listening and no fatigue. Absolutely love the imagery and extra bit of bass from these terrific headphones. Well spent money for me to just wonder off while listening to music.

I bought this headset to play Tarkov. Now I can hear the faintest movement from 100+ meters away with some of the best sound quality. This has increased my anxiety 10 fold. 10/10 headset. Oh yeah music sounds incredible to.
