Crazy how much low bass boost is in the factory tuning along with a scoop out of the bass that gives warmth and punch.<br /><br />If you continue listening, check out the increased depth of field where vocals and instruments "sit in the mix" with the filter engaged.<br /><br />Lol!

I've received AKG K371 today and tried your EQ for them--indeed it sounds much more natural than the factory tuning (I guess they are tuned to the Harman curve) which has too much bass and exaggerated treble. I'll give it more listening this week. These AKGs lightweight indeed, but I'm not sure how long could my ears stay cooled in them--it's been just half and hour and Mikhailhttps://www.blogger.com/profile/03247181793198240403noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-44161776135393868162022-03-18T15:10:03.051-07:002022-03-18T15:10:03.051-07:00Cheers Mikhail!

I will be revisiting this soon for another round when I can find some time. I agree, with DSP tools, it is more about fit and comfort than the factory signature, which for some reason are either wildly bass shy or the scooped "boom, tis" sound.

I'm not questioning your perception, but I'm really curious about the roots of the "speed" phenomenon—is it purely physical, e.g. can be predicted from looking at the waterfall graph, or is it more psychophysical, and might depend on less obvious things, for example, amount of bassMikhailhttps://www.blogger.com/profile/03247181793198240403noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-29950765241023426342022-03-14T21:04:14.761-07:002022-03-14T21:04:14.761-07:00BTW Mitch, looking forward to hearing more about t...BTW <em>Mitch</em>, looking forward to hearing more about the Abyss AB1266!<br /><br />Jeez, that's an expensive headphone man.

I replaced them with HF3 and had a set of customer ear moulds made for enhanced noise isolation and comfort. If you don’t do this I recommend a way to cut down wire noise is to put them in upside down and loop the wire over the top of your ears - big improvement. <br />Giraffehttps://www.blogger.com/profile/04391613140895834062noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-192976138038620092022-03-13T08:04:44.980-07:002022-03-13T08:04:44.980-07:00Etymotic's were my mobile IEMs of choice for w...Etymotic's were my mobile IEMs of choice for well over a decade. I think I started with the ER2. Used to do a lot of air travel and never got along with the various noise canceling headphones. These gave me enough noise isolation and a good listening experience. Agree that they tend to be too flat. Good to see the measurements to put that into context with other measured IEMs.Doughttps://www.blogger.com/profile/12981828921649308703noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-80264347543742248452022-03-12T21:23:45.591-08:002022-03-12T21:23:45.591-08:00Great posts, Archimago and Mitch!

Myself, I'm a big fan of Dr. Griesinger's research and use his DGSonicFocus app as a generator of banded noise both for fine-tuning a stereo speaker setup in a non-symmetric room, and for tuning headphones to sound right to my ears. I like when sound sources have well defined positions in the aural image, so I make sure that all noise bands sound centeredMikhailhttps://www.blogger.com/profile/03247181793198240403noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-31705296639457548482022-03-12T18:08:20.761-08:002022-03-12T18:08:20.761-08:00Pic/measurement above 'I.
