I didn’t add a treble filter, but if you want more air feel free to add a Low Shelf around 10 kHz and boost to your hearts content.

Additionally, this profile might look a bit different than people are used to from this thread. It doesn’t quite follow the “center” of the bounds or the “Harman Filters” I’d used prior, but that’s because it was instead generated with a new version of the bounds we’re currently working on. Can’t say much more beyond that, but feel free to let me know if you want something different, X2jo.

Excuse the formatting, this is my own measurement of the Audeze iSine 20 with stock tips on the B&K 5128, but it’s just labeled by the tip name (Stock).

The very first profile here was the HD800S, but how about the OG HD800? Shouldn’t be much different I guess

Is the implication that I choose the most consistent (confidence: high) headphones and use your excellent EQ approach in order to get the best-sounding / most neutral experience? If yes, would you mind sharing high-value, consistent / confidence-inspiring options?

How about the Stax L300?

Requesting politely again a profile for the Audio-Technica ADX3000 please :blush:

Requesting Hifiman Mini Shangri-La
I don’t think there’s enough measurements of it, but I’ve EQed it solely by ear about as far as I’m able so I might as well ask.

Bought the Edition XS for this profile. Sounds nice, I think I made the right choice. Thank you!

Hey @listener and Headphones.com team!

Love this thread, I’m in here a few times a week referencing your work for different headphones.

I wanted to respectfully request a few(please forgive me if I missed one of these from earlier in the thread):

Moondrop Kadenz
Sennheiser HD550
Focal Elegia

If you find time to take a look at those or not, I wanted to give you a massive thanks!

This thread has been incredibly useful. I hope one day it could find a more formalized home (I have found the search/ctrl+f hunt not ideal) maybe in whatever measurement tool you all have been crafting.
