Hifiman HE-300 mod removes the dark sound - Page 6

Then I read about this mod, removing the felt.  I did it.  When I examined the felt, I certainly theorized that removing it would be a good thing.  Earlier posts to the effect of "No one would ever make speaker grills from this stuff" seemed spot-on to me.


I plugged everything back in and fired it up.  The results were severely disappointing.  I spent many hours listening and my initial inpressions were borne out - unwelcome sibilance, excess brightness and harshness.  I found listening sessions substantially more fatiguing, much more quickly.  Nevertheless, I ran this set-up for nearly a month, listening for hours every day.


Now I've put the felt back in.  The harshness is gone.  I can listen for longer without tiring.  What's really odd is that I am satisfied with the volume knob turned up less when the felt is present.


Maybe my ears are weird.  Maybe I just prefer a much darker overall sound than most folks.  Maybe I listen to crappy music that's recorded harshly and the darkenss of this setup is euphonically camaflouging upstream problems.  However, I don't think so.  I have some beautifully recorded DSD files of classical music that I like better, too, with the 'phones in their stock configuration.


Whatever the reason, I found this mod to be severely counter-productive for me.



I agree. My setup is very simple compared to yours, running the modded HE-300 through a FiiO E07K, but I also ended up fatigued after 30-60 mins of use. I did like some aspects of it, like the perception of a wider soundstage and a tad more clarity, but the harshness gave me headaches. I have to admit that I do personally prefer darker tones due to my sensitivity to sibilance, though. Grado lovers might find it more to their liking.


All in all, I'm very happy with the sound coming from the stock HE-300.

Just did the mod and replaced the stock velours with some stock d2000 pads. Comfy and less itchy. The sound opened up a little but definitely isn't a night and day difference. Probably cause I'm not using velour anymore.

Tried this little mod and sadly the massive drop in bass was not worth the clarity improvement.

I just obtained another pair of HE-300's at a ridiculous price, and did my aforementioned mods right away. Night and day difference. Gone is the dark, overly warm sound. Hello detail, better soundstage. The sonic veil is cleared away. I'll be trading out the pads for a set of Focus pads when they get here in a few days. The Focus pads are damn comfortable. I promise myself I won't sell these. But then again.....haha!

I went and quarter modded the felt and put the felt back. Darkness still removed but the mid bass is back up to where it should be. I've left 4 holes uncovered and that puts the bass right where I think it sounds the most balanced. As noted earlier is this string, opening more holes takes away bass, unlike Grado's where porting their drivers increases the bass.


These are fun headphones to mod and play with, and wow, even to listen to. Imagine that!

After doing the mod and plugging in my HE-300s my music is singing again.  Thanks everyone!
