Awesome Buy

Bought this as an early Christmas gift for myself and was not disappointed by it one bit. Definitely worth the buy.

I just purchased my HD660S2 on Black Friday, upgrading from Sennheiser PXC 550 II. I'm a lifetime music lover that just in recent years got interested in hires lossless music. The 660s2 along with Questyle M15i DAC using 4.4mm balanced output is a tremendous sound quality difference with Qobuz music. I can hear a lot of little nuances in the music that wasn't noticeable previously.
It was a great investment that I had on my radar for a few years.

Break in is not an option

Pushing them with a McIntosh 7200 and honestly my first hour was pure buyer’s remorse. After 10 hours not so muffled but hoping for more clarity especially in the treble range. Bass is not the problem. So hopefully more time may help but we’ll see. You’ll need an extension if you’re going to be couch lounging. What’s with the useless black bag? Really?

Best one so far

I went to these from some DT 990 Pro's 250ohm. and lemme tell you something. its been about 2 months but im still sold that these will be my forever headphones. I have never felt that way about headphones. They sound FULL, very full. Super detailed and clean, and pretty good sub bass. I have them paired with a FiiO k5 pro

Not the upgrade it is purported to be

Touted as the upgrade to the HD 650, but it's more like the upgrade to the HD 58X from Drop.
Doesn't have any of the midrange magic of the 6 series, has meaningfully brighter and harsher treble, and is significantly more expensive. Looks incredible (love the colorway) but sonically it's a miss for me across the board.
No, I would not recommend this to a friend.

Awesome upgrade after 20y

Sound is superb. A great upgrade from HD 650. Not as amplifier dependant. Not as colored as 650. Just as detailed & vivid but more neutral overall, plus subbass which is lacking in 650.
I would recommend this to a friend!

really good

amazing sound quality + comfortable ear-pads. Love that my ears can finally breathe during extended wear periods. my only complaint is they fit slightly too snug, and perhaps too little padding on the top band. Overall, very satisfied. Thanks

These are the most well made and comfortable headphones ive ever used. Honestly unmatched in sound balance & quality, although I do have some issue w getting it as loud as Id like, but that could be due to my interface. all in all for comfort & sound I give these a 10/10
