Very nice. Mate. I'm glad you do enjoy the MH335DW. I'm looking forward to mine soon too. There is something about the FitEar signatures that let you enjoy the music, yet to a certain extent, also educate ones ears to appreciate the subtleties in your on sweet time. It doesn't throw everything in your face at the same time which could be overwhelming. I hope this is the end game for you for IEMs too .

"On low gain and at a volume of 200, the MH335DW was able to image (without raising the volume further) bass response from 360 cycles to 10 cycles in one go." - Are you saying you heard a 10Hz frequency sound wave?

it was more "felt" than heard.

You mention how sensitive they are and how with devices you tested them with they sometimes produce hiss, ranging from none at all, to almost none, to minimal hiss, to heavy hiss. Where does the DX100 / HDP-R10 fall in this aspect?

I like your review and if you indeed felt a 10Hz wave fundamental and not just its harmonics then the MH335DW has some pretty impressive performance. Especially as a 10Hz wave requires 34.32 metres or 112.6 feet to realize one full cycle in 20 degree celsius or 68 degrees fahrenheit air.

Hey guys,
wizard, unfortunately my HDP-R10 is not with me at this time, since a friend is borrowing it, but I do believe there was some hiss, very minimal.
temporary, thank you very much, I appreciate it. I'll try it again and see but I definitely felt it...

hey Zero, it was a pleasure reading your review.
 
People on web keep telling me mh335dw is bass heavy.
 
your review tells me something different.
 
I really don't know what to do. What do you think?

i feel really jealous about you. I tested the MH335DW before, and i really love it. I'm from UERM, and i love it too, but after i listen to this MH335DW, i felt that this CIEM fulfill what i think the UERM missing and enhance what UERM has.. If my UERM was spoiled and i got money, i will COME TO YOU FITEAR!

The Bass extention to the mids is really a point to consider and bothers me since I listen more Classical music. What is the Fitear Custom which has a better signature for Classical music ??
