Ok, so now that I calmed down in regards to that stupid build quality issue I was experiencing, I'm currently having another listening session with the
NDH 30, counter referencing with my other devices.
I feel the width is natural. Not overdone like on my
AKG Q701 but not narrow like on my
HD650. It still struggle with width in the low mids and it's obvious on FKA Twigs - Two Weeks. It's a tad recessed.
The depth is lacking a lot. Very 2D like. Also reminiscent of the
HD650. Not necessarily bad per se as I do find that desirable in a lot of cases when mixing. Less when mastering as you need a clear representation of instrument separation. This is something you can clearly hear on Royksopp and Robyn -
Monument.
The frequency representation (after Sonarwork correction) is only lacking in the sub frequencies. It become mushy like a cheap sub. The rest seems well integrated. Without EQ, it is still very acceptable ''as is''. I would actually advise NOT to EQ correct the cans when mastering as it seems to give some extra flexibility to the cans Headroom as they sound like they are not working as hard to achieve a good representation. Also, the 3khz and up seems to be more dynamic without EQing. I prefer the
HD650 Mid high frequencies but prefer the Mid lows on the
NDH 30. More on that later on.
I find the
NDH 30 to be a lot more detailed in the Mid lows then the
HD650 but on the other hand, The
HD650 sound more detailed in the Mid highs to highest frequencies. But seems to lack a lot of definition and details in the bass frequencies.
The
NDH 30 gives better step response then the
HD650 but both are seriously lacking under 400hz.
Overall, I think the
NDH 30 are an upgrade to the
HD650 but staying in the same ''comfort zone''. Just a different representation.
Now I did compared both the
HD650 and the
NDH 30 because they are very similar in many ways. I would call them both Great cans. Even put them both in the ''must have'' or ''essential'' categories.
The Build Quality ( putting aside the stupid Jack insert issue on the cans ) of the
NDH 30 is Great. The clamp is a little strong for my head but I believe it will get better as time goes. The headband does hurt the top of my head as well but again, I will probably get use to it.
In nowadays market, I believe there is many MANY cans that can be better tools then those 2 excellent cans. Some of them will undeniably be a lot more expensive but others can still be found in the same price range.
One that come to mind and that use are the Hifiman Anando Nano. I know it's quite controversial as Hifiman has many report of bad quality control and return/exchange issues with their customer support but I am not experiencing any of that as we speak. Compared to the
NDH 30, the nanos are everything a mastering engineer would love if used to work in a well treated environment and monitoring on high end, flat and low distortion sealed cabinet monitors like the Lipinski's
L-707. This is something the
NDH 30 fail to deliver. It is very obvious that even though the mid lows and bass are very engaging, they are also very saturated. I don't have measurement to support my claim but it is too all up in your face and lack too much definition to be remotely called natural. Again, not saying this is bad in a mixing situation but definitely less then ideal in a mastering situation. On the other hand, the nano's are shy in comparison but provide A LOT of movement and details from sub to high frequencies without missing anything.
Listening to both the Nano's and
NDH 30 back to back, the Nano's sound like they are light and lack a spine (not saturated in the mid lows nor bass section). But after a few seconds, it become clear that this is to the
NDH 30 detriment as there's basically no dynamics and details in comparison. In reality, the
NDH 30 do have enough details and dynamics to make confident decisions in a mixing situation but do lack the extra mile to make macro details decision.
The
NDH 30 are a lot more ''listener friendly'' then the Nano's. It feels engaging and warm. The Nano's are really a clinical and asepticized cans. They gave me an headache the first 2 days I used them as my brain was struggling to deal with all the info in the high frequencies. If one was to think about buying them, I would HIGHLY suggest to send them to Sonarwork for individual calibration. It does make a HUGE difference as planars take EQ corrections like real champs compared to dynamic drivers.
I would recommend then
NDH 30 to anyone looking for an engaging mixing set of cans. They sound great and fun and I can definitely see myself using them on a regular basis when mixing.
Now, keep in mind that
this is only my opinion and that perception do vary so I can see why someone would have a different opinion in that regards.
I cannot master on
KH420 because of their tweeters inconsistency but there's many other M.E. that swear by them. Some other are into Focal Trio, others on ATC's....I'm on Lipinski's and love their rendering. No one's right or wrong.
Pick your poison and feel confident about it.
