The best DT990 =

Chrome edition 600ohm

That said, the pair you have may have an extra filter disc installed to damp highs.

Lol that statement has nothing to do with inebriation.

It’s actually a technique first used to international audio acclaim in the Sennheiser HD-800. There are numerous articles in European and North American hi-Fi media outlets in which Sennheiser engineers talk about the strategy behind tuning the HD-800 the way they did.

The tuning was specifically attenuated in that frequency range to portray a sense of distance from the source sounds in that frequency range. Not quite the explanation you imagined earlier, eh ? You thought it was a joke. Joke is on you, son 😎

You cannot. But you can give the illusion of instruments being farther away by recessing the mids, especially the upper mids from 900hz-3khz lol

It is overhyped. But it’s FR from 90hz -3.5k is literally perfect. And it’s very comfortable. It just isn’t particularly fast, detailed, and has dim boring subdued VEILED treble. It also has poor soundstage for an open back.

I have long wished that sennheiser would have released an HD8__ edition which had the HD600’s FR from 90hz-3.5khz, instead of the scooped upper mids we got in the HD800/800s, that is used to simulate an even larger soundstage, close to the AKG K812.

WORD.

Harman target curves are all too bass-heavy IMHO.

IEF NEUTRAL is my ideal.

Cables >>>>>>>> wireless.

Until wireless can AT LEAST transmit 1411kbps+, and overcome the size limitations on how drivers and housing combine to achieve further true extension …. Or come close to the soundstage of real open back cans … they won’t stand a chance at overtaking the market share of true audiophiles, much less audio professionals.

I love the 660’s speed and overall feel. But felt it was not enough mid presence like the spectacular HD60”‘a mids, and significantly too dark in the treble and not quite enough sub bass.

Let’s hope for another “Grey speckled recycled plastic” classic HD6__, hopefully in a l three Grey color than the HD600 old speckled charcoal color.

And with all the technical advantages of the HD660, but with the exact same tuning from 500hz-5khz as the HD600, air like the HD800s, and sub bass like the HD650.

This would finally get me to own and keep my very first sennheiser

I understand your excitement for your upcoming headphones, but before speaking C so demonstrably with such assumed authority next time, limit such passionate comments to headphones you have heard in person, over a wide variety of genres and volumes

The Xs will be a very significant upgrade over your M50x, which while decent in the midrange and lower treble, has badly bloated muddy bass

It’s true that recessing in those regions does give a sense of increased distance of instruments. But to me, the K812, HD800 & 800s already do this to its maximum tolerable level. Hifiman’s range overdoes it in an attempt to maximize percieved soundstage width, and it comes of too contrived to me.

It’s also my biggest critique of the K812 & HD800 lines.

The frequency dips exhibited across the hifiman range are located in two specific frequency bands, and those bands and several others are often the distinguishing factor between a professional or reference quality headphone, and one meant to maximize consumer enjoyment of poorly recorded music from the last or indie groups of the present.

Hifiman range house FR tendencies are not there to be neutral or fully exposing of everything there. They are made to make harsh recordings sound less harsh in the two frequency bands which a large segment of the population find irritating.

Problem is, when you listen to extremely well engineered well mixed great recordings, the vocals and upper midrange detail as well as percussion sparkle are very recessed in every hifiman headphone, it’s a conscious tuning choice the company has made to please a significant portion of sensitive lay consumers.

So for those who find many treble - rich headphones fatigueing or irritating, hifiman can be a good choice. But for those who want something more neutral and more honest, more revealing of every detail present, or those who need such detail to work properly, they are not the best choice.

I would also add that the XS soundstage is not superior at all to the AKG K6/7/8 series. The soundstage width does come very close though. But because of the tuning, they simply cannot match the upper mid fine detail and high end sparkle and overall FR honesty in the similar width space the XS can provide.

AKG’s k6/7/8 lines can do more detail and more sparkle and more revealing, accurate placement, in a giant Nearly 360’ space, as opposed to just a laterally wide space

I disagree. Hifiman’s entire range, while technically impressive in some aspects, all seem to have unnatural, recessed ranges in key frequency response zones, namely, from 1.5k-2k, and from 9k-10k. I am very very particular about these ranges, and especially avoid headphones without sufficient presence between 1k-3k.

I don’t dispute that the edition XS is impressive for its price in some regards, but it’s frequency response adjust has two glaring spots I could never tolerate, nor fix with EQ, without introducing other problems which would proclude them from being used in reference work and sound design work.

HD600 has a truly pleasant, classic, and honest midrange frequency response that is the best in the sennheiser HD6 line. While it does have a little rolled off sub bass and some veil of the treble, and the soundstage isn’t very large like the AKG’s … it’s truly great for intimate genres of music.

Sennheiser soundstage and directional imaging under $500 … simply aren’t anywhere near as large or expansive or detailed in that space, when compared to AKG in the same price range.

AKG K612 is one of the most underrated neutral/lean headphones of all time. While it’s sub bass is rolled off, the mids and treble are truly incredible for its price. And it definitely has the full K6/K7 soundstage.

I don’t own them, since I own the flagship K812, but for those who don’t mind rolled off bass, or who want less thunderous bass for gaming advantage (as opposed to gaming enjoyment), the K612 is great.

For those who want the AKG K soundstage, but can not tolerance sibilance, or fatigue quickly from piercingly accurate treble … the all black first edition MASSDROP K7XX has a much more “Sennheiser warm/darker” frequency response than say, the piercingly bright K701. In between the two is the Quincy Jones Q701.

AKG K6__, K7__, and K8__ have literally unbeatable soundstage width/depth/space, and 3d map placement accuracy.

Only Sennheiser HD800 and other even more expensive headphone series comes close to the AKG K6/7/8 soundstage.

And of all the more expensive models which can come close to the size of the AKG K6/7/8 soundstage, very few can also match that size with the audio accuracy, audio detail, and very revealing and relatively flat frequency response curves with extended treble for additional nuance, within that expansive soundstage.

Coiled cables are the best tho ! Why would you want it any different ? Coiled cable stays shorter and manageable at close range, then expands as you move around the studio (or game room/etc)

Word lol

2nd biggest bloated pet peeve of mine ! Can’t we just get some great perfect FR’s already in 2023 ???

Best headphone meme in tandem with my biggest pet peeve in tuning… that I’ve ever MF seen !!!

A+++++++

📐A million cuts 🔪to Raycon !!!! They must be punished !!!!

Find appropriate jaw and neck exercises to attempt to get a more symmetric seal.

Whichever lobe protrudes more, try to be conscious of really flattening it as much as you can when your head rests on that side of the pillow.

There definitley shouldn’t be ONE.

Multiple target curves, for a wide range of tastes and applications, is best.

Headphone tuning from the factory, should be able to please several different curves, with multiple pad options to customize it.

This is the real future of open back high end headphones. Flagship models capable of competently delivering several different target curves, on the same model with quick swaps any user can easily do.

Word. The consumer market right now is almost all slightly too bass heavy.

There are many different target curves, some for each taste. I find the Harman nearly perfect in the upper bass, mids, and lower treble.

Bass & sub a little too heavy, far upper treble barely too dim.

I personally find the Hartman curve slightly too bass-heavy. It’s definitley not for everyone.
