    Honestly the laughter I got from this picture is well worth the wait of the headphones. Like how did they even manage it. Guess I can do the grill mod whether you used 3M tape or not : )

    Has anyone tried running the Verum's with an NFB 11.28 dac/amp?

    @Garuspik,

    The Verum 1 suddenly reached my door today. This is the 1st time ever (and I mean, ever) my custom didn't slap a tax on me. I was really surprised and wondered why. When I got the package, then I understood why. There was no brand no nothing. You smart man!

    The headphone itself is good. Only small complain I got so far is that the left channel often gets silent, and I have to frequently re-align the left cable. And the headpad is slightly mis-aligned. But I think it will follow my head's contour later on.

    Build quality is still far below the 2C, but above all my Hifimans. It is very good for the price. The carbon-fiber/silver grill mix is great. I'm glad I chose it.

    Chain:
    Modi Multibit v1 and THX 789

    Test track:
    Charly Augschöll - W Space of Fantasy
    Blues Company - Cold Rain
    Chris Jones - No Sanctuary Here
    Eagles - Hotel California

    As for the sound, I agree that this is sort of planar version of HD600. I was expecting a darker sound, but it came out neutral. Can lean towards slightly bright-ish. I still prefer the smoother and more detailed mid and treble out of my HD600/650, but bass is more solid and extended out of the Verum.

    Its sound image is also quite large, probably due to its large driver size. Tonality is like a neutral Audeze. It's got the heft that I like from Audeze, but missing in Hifimans. This makes a great complementary can to the 2C.

    I'm getting good depth and center image. Width is similar to HD600. Separation is good and images are clear within their own spaces. Bass is impactful. It is more focused and less thumpy than the 2C. For me, this is the highlight of the Verum. Vocal sounds neutral and clean. Impact is nice. Solid and focused.

    This is a nice can.

    Thanks, also it was registered on my customs with a low invoice so all backers should avoid additinal charges.

    Please check whether it's cable (swap channels) and make sure you've connected cable till click into female sockets. If not - i'll send you a replacement. But it looks like cable, swap channels and please tell me the result.

    It's made from spring steel. If it's slightly missaligned - bend it a little. Or leave as is, it doesn't affect wearing.

    Thanks. Will try to improve.

    p.s. I use same cable as Hifiman (2.5mm sockets in cups) please try another cable as you own Hifiman headphones as I see.

    It's not the cable. I swapped left-right channels. And I tried my own balance cable.

    It is the connection on the headphone. Somehow, if I connect it till click, it often gets silent. Then when I take it off a little bit, and turn around the cable, the sound comes on and off.

    Right channel is perfect. Any idea, mate?

    It is not the spring steel that is mis-aligned. Just the padding.

    I wish this unit was checked properly before getting sent out.

    Then it seems like a bad 2.5mm socket inside cup ;( PM me and we'll discuss a replacement of this cup.

    Question, do you know, for cables coming with Verum 1, can 3.5mm jack be cut off and 4-pin XLR soldered in? Are there enough wires and they are not shortened at Y?
    Thank you.

    It's such a thin cable that I just ordered one prebuilt from Ebay. I'm gonna wanna have an SE cable for other purposes too. I'm quite happy with the headphone as is.
    One speaker or another cuts out on occasion. While playing, it first starts to fade away and then silent. It's not the cable, it's not the socket. It is some sort of unknown phenomena (to me anyway), I give it one or two light slaps and it is back in all it's glory.
    I have learned to take the headphone off first. ;)
    I am curious about this and would like to figure it out someday, but until then, I'll just enjoy it.

    Guys, you’re frightening me. Each headphone is playing for an hour on HUGE volume before I pack it. I don’t understand what’s going on, but I need to understand this. Shipped almost 200 pcs, >100 delivered. Asking many people about cutouts and other weird things - no problems. Has many clients in Ukraine that are using them everyday and whom I can call - same, no problems. Ship me headphones back and I’ll examine what’s weird in this particular unit.
    Also I’ll be thankful if you use for a day another amp and tell me whether problem is still there.

    @Dzerh - it won’t work, only 3 wires after Y splitter.

    Worry not, I have another cable coming. I don't use the Hifiman cable much because it's too short. I will switch to that one though for trouble shooting and I'll bring out another amp that has not found a buyer yet. I actually have 2. I use the THX789 and Loxjie P20 currently.

    1st result:
    Project Ember could not handle this phone on it's .01 output setting with a 6sn7 tube, using low gain setting. The phone cut out quite a bit, both drivers.
    It may provide a clue though. It may just be running out of gas.I will try again on high gain later.
    I am back on the THX789 but with balanced input and it is running perfectly. It usually runs well on this amp using SE input with an occasional cutout once in several hours to 2 days. I'll let this run for several hours over the next day or 2 with balanced input.

    2nd result
    THX789 balanced input, right channel cuts out at 45 mins, 30 seconds later the left channel volume increases on it's own. It really sounded nice for a while too. This has to be the amp, right? A tap on the right speaker brings it back but volume has increased on both channels. The THX789 is rated down to 12 ohms, stating 16 ohms and higher is preferred, 4 volt peak limit between 12 and 16 ohms ....Bring on the MCTH.....

    Early MCTH results, so far so good , stable, will play several more hours at least, tomorrow.
    The 8 ohms impedance makes me wonder if a speaker amp might be suitable. I have an Adcom GFA 545 unused???

    Annnnnnnd i should check this thread before i cut it an hour ago.

    But seriously, my initial listening leads me to do this as i gets too excited to hear how it will sound in full balanced setup , good job!!

    @bilboda ahhh(sigh of relief) so you have an amp without any problems running Verum1 and without any cutouts. That means that they’re working as they should but picky about an amp.
    For me as a manufacturer very important to bring consistent quality and when I read such things that a real catastrophe for me.

    @manatworks - you’ve received your pledge already? When you have time please post your impressions.
    About balanced cable - I don’t know where to get cables, but balanced cable for hifiman will work perfectly.

    No worries, i’m soldering my own 3.5 plug back so i can give them more listening time. Too bad my desktop setup limited my connecter to XLR 4 pin but this already sounds great out of portable gears.
    Once i give it enough listen i will post my thoughts here.

    I'm running Verum (not mine yet, from an acquaintance) on my THX now. Yesterday I've listened for a couple of hours and had a feeling once that the right channel got quieter, but thought that it's my glitch. After your post, I'm curious if it's the mismatch with impedance due to THX limits. Will listen to it extensively today and will report any problems, if any.

    If you was listening to headphones for a couple of hours I assume they're not horrible;)
    As for such weird problems with THX 789 - i've studied what's inside. This amp is using opamps OPA564 as a power output stage. They have thermal protection when they limit current. Maybe (but I'm not sure) opamps are overheating when working on such low ohm load and protection start working?

    p.s. And iphone is cool and stable for 10 hours at least ;)

    These are quite far from horrible.)))) Yet I cannot say that they would replace my HE560, as in some areas 560 are noticeably better, but Verum excels in other things so I guess I will have two pairs of headphone to switch depending on my mood and particular music. I have some suggestions about earpads, I will write to you later via email about those.

    BTW, what kind of earpads did you guys try with Verum, can you share your experience? I tried my Dekoni for HIFIMAN (I love those!) and these are too small to fit the rings (I just put them inside cups temporarily holding them with my hands while putting them on my head). Which models of headphones have 105 mm earpads? Usually, producers do not state these measurements. I would like to know which Dekoni pads I could order that would fit Verum? Dekoni have dedicated product lines for Audeze, Focal, AKG 7XX, Sennheiser 600, 700, 800, Beyerdynamic DT series.
