Some initial impressions...
The soundstage and imaging and resolution of the ceramic tweeter is its strongest capabilities.
The soundstage is pretty oval shaped, definitely more wide than deep, in comparison the M-Audio Q40 is like the opposite, a bit more narrow but very deep again with lots of center focus so it's an interesting contrast, I feel there's not that much of a center focus, it's more of a speaker-like stereo presentation due to how wide it is on the 1More TDOEH. Ideally I'd want perhaps slightly more depth for better balance between width and depth but yea it's not too bad though. Imaging wise this is probably the strongest point of this headphone, it has an unprecedented capability (to be a closed on-ear headphone but it does a good job at its price vs other types too) of put different instruments in space and with superb separation, like every sound is so well percieved in the mix, the Q40 for example can't separate instruments as well but I still consider it decent and it has a very musical sound again meanwhile 1More TDOEH impresses on a technical standpoint, you start more paying attention to details in music. A good example here is Johnny Cash's "Hurt" where the guitar, piano and vocals are always so wonderfully separated at all times.
The resolution of high frequencies right off the bat is very impressive, I don't feel this is a brighter headphone than Q40 with how I added slightly more depth to stock pads of M-Audio Q40 by adding a layer of kitchen towel paper beneath the pads which brings the highs out which I feel balances out the overall warmth of Q40 to be a bass focused with punchy bass but otherwise very balanced sounding headphone. But the 1More is probably like slightly harsher around certain frequencies and Q40 remains very "soft" in how it presents the highs even if the mod brings out the highs more (sometimes I always appriciated that I typically only experience with open-back headphones). The 1More has slightly bit more resolution to the highs though but it does it in a way that keeps 99% of the time without giving annoying sibilance, it's right there on the border where it should be.
The mids I'm slightly less impressed compared to the highs of the tweeter, balance-wise they are pretty fine but I feel there's slight lack of organic feel and there isn't as much resolution going on here as what comes from the treble in the ceramic tweeter but very good for the price still. I feel it's very much in balance with highs though so that's good. I might ever so slightly overall prefer mids of Q40 which has a very sweet romantic mids that is lush and captivating and it somehow engages you into the music better but it could be due to the fact the Q40's soundstage is a bit more "in-your-face" sounding and the 1More ever so slightly more laid-back/distant with a bigger stereo image separation.
The bass is pretty different compared to Q40, the 1More is like slightly more subbass focused and Q40 in comparison has slightly more midbass presence making it more punchy and impactful especially when comparing modern EDM music. Both headphones do bass extremely well in terms of texture (Sony MDR-1A was a joke in comparison with a very boomy textureless subbass note), I find the Q40 does that perhaps slightly better but it also has more punch and weight/impact to it, you feel the beats in eletronic dance music better. But the Q40 is probably has the most textured and punchy bass in a closed headphone you'll find anywhere the price range I'd imagine. The Q40 on the DigiZoid ZO amp whit 16 different bass level settings I prefer the middle "8" whereas the 1More I think sits at 12 or so where both headphones provide the ideal impact vs quality ratio for respective headphones, Q40 still deliver a better feel the bass sensation (think how you feel the drums standing close to a drumset, the initial slam is felt more). But it comes quite close with the different settings on the amp though and even at the lvl "12" it remains free from muddying up mids, it just provides more slam to the bass while keeping a nice texture still and I like how it sounds in pretty much all genres with those settings.
The comfort seems pretty good, I quickly tested swapping around L & R and swapped cables around but I'd say I slightly prefer it the standard way around as far as sound goes, not a huge difference but I feel there's ever so slightly more crispiness to it and to me it works better for me/this headphone. Maybe pads get slightly sweaty but they don't feel very hot though after use, have had a lot worse pads in that regard. Clamp is pretty average, I'm the person who prefers a bit tighter clamp to ensure best possible isolation & bass impact and for this headphone it doesn't seem like pressing on the cups cause better isolation or impact so I suppose the sealing is good which is a good thing for my tastes.
Initial impressions are pretty nice and they definitely are a good sounding headphone at its price range, it can be that the bass isn't quuite where I wanted it to be, I was hoping for a bit more feel-the-bass sensation to truly satisfy my Hardstyle music listening needs, this is the sort of headphone I rather go to listen to some acoustic music instead and listen to how nice separation going on. Probably will keep this headphone even if it didn't get that much use or if I only started listening to specific music / non-bass centric music on it because I feel it's pretty special with it's triple driver config and the interesting design I quite like.
EDIT: Also gotta say the impressions just unboxing this thing were very good, the headphone certainly is boxed like a much expensier headphone so kudos for that to 1More team.
