    Those two are totally different tuning wise while the other HD 600 series aren't exactly. Though, I don't think the tuning choices they made for HD 660 S make much sense. At least I don't get it.

    DT1990 and Hifiman Sundara have recessed upper mids and strong treble peak around 9K while HD 660 S is flat in comparison (more upper mids). Other HD 600 series cans have even more upper mids and have very smooth frequency response without large dips or peaks.

    Safer choice means HD660s has the least amount of treble, so it won't sound sibilant.
    DT1990 will sound sibilant on poorly mastered tracks, Sundara also might be affected by it.

    So HD660s will sound as good as it gets from the box. While DT1990 require some EQ to make it less aggressive in treble. Sundara sounds good without EQ, however might be sibilant to sensitive ears.

    Your analysis of the DT-1990 should include which pads you are comparing. Based on your description, it would suggest the B-pads.

    Whit a 10-15dB spike around 8K you'd actually need really poorly mastered track (as in track void of any upper treble content) to make it sound neutral. 5K to 8K difference is about 20-25dB. There's no way that could sound right no matter what track without EQ.

    As far as I know the balanced pads just add a lot of bass and midbass while upper mids and treble doesn't change much. Might help with overall impression but it actually means that upper mids are even more recessed in comparison to other areas. Both have massive dip around 5K and strong spike after that. That will likely make sibilance more obvious (somewhat like HD 660 S) while the 6K isn't really over the top. However, it keeps going up and up till it reaches 8K. It's probably more like overly sharp and piercing rather than sibilant.


    What's weird with HD 660 S is that on paper, the differences should be rather minimal to HD 650. Yet the timbre is a lot different and doesn't sound quite right. By the way, quite funny that Sennheiser sells HD 660 S and HD 650 both for $499.95 in their US web store (as far as I know HD 660 S is the only one that comes with fancy box these days - also balanced cable). In their EU store HD 650 is 40 € cheaper (459 € vs. 499 €). In actual shops HD 650 is 329,90 € and HD 660 S is 429 € though.

    Though, AKG is nuts asking $499 for K712 Pro in their US web shop. That costs 199 € here in typical shop (including 24% VAT). It's pretty meh headphone in my opinion anyway, so at $499 the buyers remorse would be super high (it high when I bought mine at 234,90 €, at least now it's cheaper...).

    Ehh... Started testing HD 58X Jubilee again since I wanted to properly test it against HD 660 S. I'd actually now rate the HD 600 series like this: HD 650 ->~ HD 58X -> HD 600 -> HD 660 S.

    At the moment I don't understand at all how my HD 660 S sounds. Upper mids and treble should be more or less the same as HD 58X. It sure doesn't sound like it though. HD 58X sounds sharper and clearer with bass extension that HD 660 S can only dream of... It goes much deeper.

    Technically it's has the most warmth out of them all but basically it just means that it has much more bass (and sub bass) than HD 600 and HD 660 S. More than HD 650 too. I don't mind - adds depth and body/oomph (sub bass helps there), doesn't sound thin. It's not soft, it's very energetic.

    At this point I can't even say for certain that HD 660 S is technically superior to HD 58X. HD 58X is much more in line with the HD 650. Upper mids are toned down a bit but not really in the bad way (it might be a tad bit more neutral there; HD 600 has some issues there compared to HD 650 and HD 58X).

    Mehh... Maybe I got dud HD 660 S (which I think is rather unlikely). In an case, it doesn't seem to sound like it should in comparison to those three. There are frequency ranges that have something really weird going on. There shouldn't but... ¯\_(ツ)_/¯

    Check the drivers in the 660s are properly located.
    When my HD650 arrived something wasnt quite right.
    It took a few days to realise one of the drivers had come unclipped and was operating at an angle, it took a few minutes to fix.

    Well, I was considering some new headphones.....but after reading this thread, among others, I'll stick with my almost 7 year old Superlux HD681... my hearing isn't good enough to be that picky or pay that much....

    You missed the audiophile USB card.... https://jcat.eu/product/usb-card-femto/

    geez.... company looks like it's just out to rip people off.
    audiophile network switches, audiophile usb cables, audiophile network cables, audiophile sata cables..... wonder how much they charge for the audiophile grade drugs they've been consuming.....
