Interested now that they are on sale for $119. Does anyone have experience with them and rec them or not?
Has there been any pads made for HE-R7DX?

I wish I had had $119.00 when they were on sale as all the reviews I’ve seen say they are worth it at they’re regular price.
First Impressions
This is my first time doing an First impressions so please forgive me if i make any errors regarding to judgement.
I have just got the HE-R7DX and its good.
Break in might be needed on the memory foam pads to regain bass.
Bass (break in needed from pads)
- Light but Super Smooth
- Well spaced and does not interfere with with vocals, instruments and treble
- Prefer ZS10 PRO Bass
Instruments is not muddled up with vocals.
- Well defined and sounds great
- Smooth and lively
Vocals are great and sound real as if they are singing next to me.
- Sound like a veil present?
- Well Defined
For a my first audiophile closed-back headphone from HifiMan the HE-R7DX is a damn great headphone to listen to any genre and enjoy listening.

AND NOW I can add the Drop HifiMan R7DX to that list for things to be grateful towards Z Reviews for introducing me to - with some major modifications of course! In stock form its a decent buy- an decent headphone with some crazy potential. I knew the size of that cup with be perfect me to go to town on all the modifications I learned over the last few years- utilizing my Kennerton GH50Mk2 Fiberglass Fractal Mesh Technology and a bunch of other room acoustics treatments I learned in recording studios and from designing home theaters a half dozen times- I think I dialed in the summit limit and best performance for this headphone design if I do say so myself. Its not merely stuffing it full of wool or tape or non slip carpet rug gripper in and praying it will work- I tried dozens of different materials and honed in what works best here and every thing is hand cut and selected.
layers of fiberglass shaped similar to a Fibonacci like pattern that make the image and sound stage sound much larger than even open backs - it’s a time consuming process - this non fabric design may just revolutionize all headphones designs and hopefully one day replace the use of typical fabric (figure a) which tends to mute certain frequencies -I can see this being the future of headphones and can replace all fabric in headphones with the fractal (figure c) fiberglass mutipatern actually helps bring all frequencies out and expand them (see image)
the pattern I created here actually de-accelerates the sound waves into a very spacious sound “meshing” unlike fabric which has a deadening narrowing effect (see diagram labeled planar surface a) - this mesh material tunes the sound waves and it comes alive due to their fractal nature- and allows pinpoint accuracy and a wider stage fooling the waves into a creating a larger than life pattern while minimizing any echo or ring in sound waves - it works better than fabric (the idea comes from using much more expensive porous/foamed aluminum similar to ones used on the back wave of the Abyss AB 1266 TC or the Meta Material used in front of the Dan Clark Stealth or the Meta material used in the KEF speakers)
THIS IS WHAT I BASE MY TECHNOLOGY OF THE FIBERGLASS FRACTAL MESH ON:*
this non fabric design may just revolutionize all headphones designs and hopefully one day replace the use of typical fabric (a) which tends to mute certain frequencies - replace all fabric in headphones with the fractal (c) fiberglass muti pattern actually helps bring all frequencies out and expand them (see image)

this is the key to making headphones less in your head I think while not touching any frequency db (no muting)
