Damn that's a lot of stuff hahaha, what software do you use? My EQ profile is very simple in comparison.

125 Hz, -1 dB, 1.5 Q 275 Hz, -2 dB, 2 Q 800 Hz, -1 dB, 2.5 Q 1780 Hz, -3 dB, 3 Q 2250 Hz, -2 dB, 1 Q 4000 Hz, -4 dB, 6 Q 5100 Hz, -7 dB, 5 Q 7000 Hz, -5 dB, 2 Q 8250 Hz, - 0.5 dB, 6 Q (this last band is not so important)

I know it's a bit strange because there are no boosted frequencies, but here is my take: you won't need them. This headphone is already bassy, so you won't need to add any bass (maybe sub bass but idc). Mids and highs are the confused area, a lot of stupid spikes going on here. Tried oratory EQ preset but I've never found oratory presets to be the best option for my taste, and with this HP in particular, I was not very satisfied. Then tried to work by myself on A LOT of different presets, and found that adding something to this HP is not a good option at all. It only needs to be tamed.

Let me know what are your impressions. Just remember that I'm treble sensitive mostly up to 4-6 kHz and I usually like to listen with high volume (around 80 dB) .

No offence but massage chair is overrated. If you want to live or play the high life, get a personal massage therapist. A skilled one with proper education wins against any massage chair anytime. OK, I should be honest. I have not used massage chairs for about 20 years, but I doubt they can match an serious professional to date.

Until you hear about how common it is for people to become trapped inside them and someone needs to call 911 to come and rescue them out of it.

It’s crazy how if the chairs air mechanism breaks the airbags inflate and refuse to release the air and your limbs can become fully immobilized so you’re permanently trapped.

Just make sure you always use those things around another person so they can call 911 for you if the chair fails. If you live alone, don’t ever buy one.

Worth a shot! I got a couple different pads to try and find the right ones, so I'm gonna give a couple of those the shampoo treatment. For now the standard pads will have to do, not enough time left to try it with those, but either me or my mom visit every few days anyway, plenty of opportunity to bring him a few different pads to try.

Thanks for the suggestion! :) I usually hate on ears so I don't really have any expierence with them (but granted...the Grados might convince me to give it a shot myself...IEMs and over ears suck when you sit in the sun listening to Lord of the rings while smoking a pipe to be honest)

Keep in mind that rapid A/B switching tends to erase differences. That's a familiar problem for people who go to big meets where lots of headphones are available for demo and they try out multiple headphones/IEMs in the span of a few minutes; everything starts to sound the same because our brains don't have time to get acclimated to any one sound. It's a common phenomenon that headphones that sound good during a short demo at a show don't sound as good in the long run, because the sound qualities that make it stand out against the 5 other headphones the listener just heard make it too sharp or too unusual in a normal listening environment.

I've gotten headphones very close to one another via EQ as well (though never quite exact), and resolution is something that to me is mostly linked to FR. I actually don't like the term "resolution", and I prefer the term "tonal contrast", which I think is a more descriptive term for what I hear. Contrast is what allows me to differentiate between different sounds (similar to how visual contrast is a key part of how our eyes perform object recognition and differentiation), and to me, "resolution" is how easily I can distinguish different instruments and sounds. It's a very fine-grained balance between different frequency ranges (plus lack of cumulative distortion from the lower registers that might interfere with the presentation of the high frequencies) that produces the correct contrast for good "resolution".

Soundstage is the main thing that cannot be easily replicated via EQ, and that's because the headphone's interaction with your HRTF matters a lot for that. Even Dr. Sean Olive, possibly the foremost expert on headphone FR measurements, has said in the recent interview with Resolve and Crinacle that FR measurements aren't everything, and don't measure the spatial qualities of a headphone. I could not EQ my Sundara to have the same soundstage size as my Shangri-La Jr, even though I could approach its resolution and overall sound. But the placement of sounds is something I could not reproduce via EQ, the SGL just sounded more spacious. The physical sizes of the drivers are different between the two, so the wavefront that hits my ears is different, so the interaction of my ears to that wavefront is different as well. The X2 and the Sundara have similar sizes and shapes I recall (I only briefly owned the X2 years ago), so soundstaging differences should be less pronounced between them.

With EQ, I've noticed regions (different for each headphone) where the magnitude of EQ applied doesn't match the magnitude of the perceived change in the sound. I've noticed places where 0.5 dB makes a noticeable difference in the sound. I've also seen cases where I boost a range by 10 dB and it does nothing to erase a dip in that range (that's usually with closed-back headphones with undamped earcups). I've found that even if I can EQ headphone A to sound like headphone B, that's no guarantee that I can do the reverse, make B sound like A.

There's also another aspect of sound that can be produced with EQ, but not via standard EQs (graphic or parametric). I've started using dynamic EQ, which boosts/cuts a frequency band only when dynamic swings occur in that band, and that allows me to add the "punch and slam" of macro-dynamics into a headphone. So in a way, dynamics are FR too, but not in the FR that you can easily see in a graph, it's sort of "instantaneous FR" if you will. I've heard of "attack measurements" at SBAF and also of impulse response overshoot as metrics for dynamic performance (more overshoot in the impulse response level means more slam), but either way it's not something that you can easily see in the standard FR graph yet has quite noticeable effects on the sound.

My overall view is that I don't agree with people who say "FR is everything" and mean that you can just look at your usual FR graph and immediately know how a headphone sounds. Even experts like Dr. Olive who specialize in those FR measurements don't hold that view. I take the view of "momentary SPL at the eardrum is nearly everything". I leave open the possibility that part of what we perceive is not eardrum-related, like maybe there's an effect perceived by the skin of the inner ear canal. There's also the fact that our brain doesn't work on SPL, but on loudness, and those two do not correlate exactly.

I also like seeing CSD plots, as I've read that at higher frequencies (>2KHz and with some effect down to 500 Hz), our brain doesn't maintain phase lock with the incoming sound wave, but instead the perception process is triggered by the waveform envelope. I've heard it explained that outside of the phase-locking region, the brain "batches" sound in time, and perceives the total amount of sound occurring in each batch as its loudness. Longer sound = louder. My understanding of this is that if a peak in the FR (above 500 Hz or so) has a long trail in the CSD plot, that peak will sound louder than the plain FR would imply. You've already seen the demonstration of how EQing down a peak also cuts the CSD trail, so the headphone "double-dips" from the EQ, not only is the peak gone, but the amplifying effect of the CSD trail is also gone. I suspect that may be why I notice unusual effects when EQing, I'm changing the FR at the same frequencies where there is a significant CSD trail, so the effect is either muted or amplified. When I've done my measurements, it's usually the case that regions with odd EQ interactions also have longer trails in the CSD plot. Psychoacoustics is a really interesting field that I wish I studied more in college (I studied electrical engineering with an emphasis on computer microarchitecture, so outside of a few audio engineering classes, I never went too deep into that subject).

Sure I'd be happy to take a listen. I can share mine as well but I'm not sure if it would sound right to your ears or anyone's really.

I don't know how to share a txt file so I'll just paste it I guess. Here it is:

Today is my Dad's 68th birthday. He had a stroke back in december (that luckily didn't have too many after effects), but his health has been really bad since then, and he's often stuck in the hospital for a while (currently in there for 2 weeks...second surgery today).

He is bored out of his mind in there, but too tired to read, and last time I visited I suggested audio books. He was pretty into the idea, and since I know he prefers on ear headphons to anything else, I ordered a pair for SR60X for him together with a nice case, usb c dongle and a 3 month audible gift subscription. Gonna bring it to him tomorrow and help him set up audible on his phone and pick a book. Hope he's gonna like it. Also, a bar of toblerone chocolate might find it's way into the carry case too....maybe ;)
