Update: I actually used another type of micropore tape which is not as densely woven as the 3M one, I just checked, I used two layers, my bad.

Hi! So I was going to go for the Sure SRH-440's but yesterday when I went to an audio store I found that the although SRH-440's are good, however, I preferred the M40's. The deterring factor for the SRH-440's was that the cans were not very deep and my ears were touching the back of the cans, which was quite bothersome. My ears happily fit in the M40's however, so they're my choice. Hope I could help!
What's the difference between this M40X and the A700X, I know the A700X is costly and comparable to M50X but I just want to know the differences, most importantly about the clarity, detailing, instrument separation & timbre, nature of frequency response. Can the A700X give me better results in the mentioned aspects
Just bought & received the ATH-M40x mostly based on this posting. So a big shout out to the OP. I also have the Sony MDR-V6 which in my opinion is the direct competitor. The Sony has more "slam" in the lower end. I cannot say that that means the MDR-V6 is more accurate. Just be aware that is part of the sound signature.
In my opinion, you cannot go wrong with either headphone. Both offer a lot of value for the money.
Now that I've heard quite a few more cans in my time, I can confirm the M40x is V shaped like the M50x. The very upper octave is pretty bright, and the midbass hump is still there although not quite as aggressive as the M50x. Honestly the E6 doesn't add anything to their sound. I already own both the cans and that amp.
Mids definitely are recessed on these cans. I expected much forward mids from these. They have amazing accuracy but lack of mids and soundstage is disturbing.
An amp, though not required but will still be helpful. The frequency response of the cans may change due to changing load conditions at different voltage levels of the output amp of your phone/music player. An amp can stabilize that. Not to mention the decrease in quantization noise when amping a low volume sound (Lower volumes produce less quantization noise, when they are analog they can be amplified by a low distortion amplifier to produce much clearer and distortion free sound at the same volume as opposed to only phone/mp3-player at that volume)
