@Lyander Yes, I thought about HP-3 also, as both of these headphones are (rumored) using Fostex drivers. Yes, HP-3 feels better than NH, but, it's twice more expensive than NH in China, so... I think I'm fine with NH?

Ah true, I'd never have bought the HP-3 for retail price (also, the original pads are USD100... each, BEFORE shipping and taxes). On the upside apart from being excessively murky I did rather like the NH, not to mention they're significantly more comfortable to wear!

Definitely stick with whatever works for you. While I crap on the stock NH a lot personal preferences do matter :P

It's funny that I'm actually having my own NH OG on sale, as I didn't like the OG sound. It's like I had to try very hard to extract the emotion from the bass cloud, but then the slightly peaky treble kicked in and I could only cry for my ears.

Last week I saw a NH Carbon, with the microsuede pads and cheaper than mine, so I "bought the competition", and found the microsuede pads worked surprisingly well.

No good. Did you feel this way about it prior to using the optical input? What is your source? Have you compared it to the USB input?

OK, I found a coaxial cable! So, quick comparison: optical input sounds more two dimensional, mids seems thinner, and the bass seems less also... But coaxial input gives me more congested feeling, seems like it generates some sense of depth by pulling the vocal closer while optical sounds more laid back. I prefer coaxial input on Modius.

Oh, my source is Pi2AES, and I didn't use USB input for long, as it generated noise over time, replugging USB cable resolved the problem for some short time, but it would come back. I guess the problem was more on my PC.

I still listen to a recabled DT880 250 ohm. It may not have the best overall sound signature, but I enjoy it for an everyday open headphone.

Was it loose at the PI2AES side? hopefully it was not an issue with the connectors on our board, but please let us know if it was.

@Michael Kelly No, it's at the DAC side. The connect at Pi2AES is really firm! Great product!!

Ignore my previous impression of Dekoni leather pads. it was made when the polarity was inverted... I bought used unit with after market BAL cable, turned out the cable was poorly made. Now I fixed it, Dekoni leather pads sound quite shouty, hard and V-shaped to me.

Swear you need 2 diametrically opposing DACS, I try to do that.

@Scott Kramer Well, these two DACs are my attempt on this direction, but as I get to know these two more, I found the weakness on each more often...

The softer ones are really softer and squishy, one press and it's all the way to the bottom. The stiffer ones have this slight initial strength against pressing, then there are soft as well. It's like linear mechanical keyboard switches vs tactile ones...

Did yours have the soft ones originally?

Well, I happened to get two pairs recently, so one pair has softer pads and the other pair has stiffer ones. I wouldn't compare them if I didn't buy the latest bunch of Elex pads on Drop, and saw people complaint about soft inferior pads they received (and there's only one pad in the package).

It's not that much of difference, but if I pay attention, it's there.

@gixxerwimp Nah... really not good at serious comparisons... Plus I want to experiment some cheap protein leather pads on it. Now with HD6XX OG pads, this closed-back HD6XX sounds like lower mids recessed, hallower HD600. It's OK, I wouldn't complain, it's much less V-shaped than TH-X00. But switching back to HD600 / HD650 makes me appreciate the fullness of their sound.

In any case, once you get it sorted out, I'm sure others would be interested in your findings. So please do share :D

@gixxerwimp It's so nice of you! I'll post if I can get better result. (Too lazy these days...)

@Lyander Yep, I admit it sounds too warm now, as I was shocked at beginning. But about comfort, I feel the pads are a bit too thick as they squash my face a bit... OK I have a big head... I'm going to buy some thinner leather pads to compare.

Hmm, thinking that squishing the pads more might actually help? Compress the stuff inside so it's not as wub-wub-wub, but I've not got a large head so limited capacity to compare. Curious whether that'd affect sound a lot now, huh.

Just check the price here, about $15 so it's a must do (I'm in China). I don't like the dust shield cloth inside the Dekoni pads either, as it touches my ears. But those cheap thinner Chinese pads don't have the cloth so they look perfect for me. Btw, I don't really want to squish the Dekoni pads as they use memory foam, don't want to let them memorize the squishing pain.
