    The cable does work. I checked it for continuity and it is fine. Flexing does not affect it. There is just something about the right side connection though. I don't see anything wrong and I solve it by just applying more pressure to the insertion and all is good. Just not a perfect fit with the socket. This only happens on the right channel where the signal is connected to the tip.

    No need to send another cable.
    I will diy one anyway for my own desired length..

    The socket on the headphone is fine also or the Hifiman cable would also have problems.

    This is a terrific headphone out of the box and is breaking in nicely too.
    The sound exceeds my expectations.

    Finally I understood. To insert one of connectors you just need to apply more amount of force to hear that click sound (sound of locking)
    Now I'm calm, everything is working :D

    Yep, it turns out after 8 more hours that your cable is fine. I am looking for my dunce cap now. This sounds lovely thru my Loxjie P20 tube hybrid/We396a.

    A poor connection will really develop a kind of "Static" and stay on a planar driver?

    My Verum arrived a few days ago also.
    I really like them so far and enjoy listening to them.
    Amazing tonality! No obvious peaks and dips like with many other headphones. I love the bass and dynamics.
    Unfortunately they sound a little bit grainy to me, not quite as clean as my HD650 or my Aeon closed (or my Dt1990s which i don't use very often).
    But I guess that would make the Verums perfect, if they had better resolution :)

    I'm a little bit worried about the crinkles on the membranes. But they are normal, aren't they?
    In Z's review video also showed crinkly membranes, but in recent pictures the membranes looked smooth and crinkle free ;)

    I have the zebrano version. The color came out little different than I expected.
    I thought it would be a little more reddish, but the brown looks nice too.

    And one other thing:
    I think the frame is a little bit too small for me. (I'm a tall guy) :)
    I put the headband in the exact middle position on both sides (8 holes above and 8 below).
    Even in that middle position the top joint of the frame rests on the headband.
    Is is just a very light pressure that's coming through the cushy headband.
    But I belive i am getting a light hotspot after longer listening, that wouldn't be there if the frame was a little bit bigger.

    Nevertheless i'm happy with my purchase :)

    Try a lower position for your headband. Twas a bit grainy for me too thru the MD THX amp.
    These do break in. I plugged in the cables to the headphones at least a dozen times, don't know if that did anything beneficial or not but the scraping may have helped the connection. Grain is mostly gone after maybe 20 hrs of playing on the THX and it is completely gone thru my Loxjie P20 tube hybrid

    After an additional 8 hours of playing I am not having any issues with the connection after finally firmly seating the cables.

    Grain is not noticeable on mine, after around 55 hours My initial thoughts stay the same, detail, soundstage. Are these better than my HEK, HD800?.( Which I have now sold) No, but close enough for me. I do prefer balanced into my HA 1. The proof for me, is that these are my go to ones, and that was enough for me to sell the two others that I mentioned.I am still comparing these to my 1060, 560, 400i, 712. I am retired, so I so have plenty of time!.

    Don't worry it's absolutely normal. It's not crinkles and not a defect.

    In Z's review video also showed crinkly membranes, but in recent pictures the membranes looked smooth and crinkle free ;)

    Unscrew top nut. Move this nut one hole away from the each edge, assemble headband again and re-adjust head strap.
    Then please tell us if this solved a problem

    And I'm happy to hear this!

    My Zebrano/Silver pair arrived this morning and they look great. A bit darker than I thought the Zebrano would be though. I will leave sound impressions until I get 30+ hours in to avoid my typical "Oooh, new toy" feelings, lol. I will say this though, I'm currently using my M1060's stock pads as the Verum's pad openings were just slightly too small for my ears. Anyway, here are a few pics:

    Hi Garuspik would you please answer my question?
    I ask this because the "Static" maybe the reason of my left driver problem that you have no idea how this happen.

    PS. I'm the "balanced at 100db" guy. Thank you.

    Sorry, but I still have no idea why it’s playing good in se mode and has problem in balanced. Please try another amp cause it’s really interesting what’s going on.

    Thanks for the reply.
    Yes I will try another amp but not easy to find a full balance chain around.

    Or any other members here have any idea on my problem and give a help?
    My dacamp: Topping DX7.
    Output Voltage: 16Vpp(single end) / 31Vpp(balanced)
    Output Impedance: 10ohms(single end) / 20ohms(balanced)

    Here is the problem. (copy from the email)
    ****when Verum in balance and play loud around 100db. The left driver start having Intermittent noise (sound like clipping), then becomes 20db lower then the right side. On this state, even play at lower volume, it keeps imbalance. And more easy to get noise.

    The driver will stay on this state no matter I reverse L/R 2.5 plug, or reverse the amp L/R out. Problem stay on the left driver.

    However, if I switch to single end (stock cable). At the beginning the imbalance and noise will keep a short moment (half minutes). Then suddenly the driver will recover itself to normal!

    If I keep using SE, even I play the same track on higher volume (110db I guess). The noise and imbalance WILL NOT happen.

    The right driver always work fine no matter balance or SE. I can repeat this problem if switch back to balance and play loud.

    This is what I found at this moment. I'm not sure the SE can keep this driver stable or not. But I feel sad if Verum just can run fine on SE. Balance always are my standard.****

    My system chain in balance get 20ohms output. Is it too high for a 8ohms Verum and cause this strange problem?
    Any suggestion, hints, advice are most Welcome and appreciated. Thank you.


    edited some typo, by my best.

    Wow, thanks for the nice pics! Now I'm confident that changing my order from Carbon to Zebrano was a good move!))

    10 ohm output on your amp is a mismatch single ended. Obviously it works single ended. . 20 ohm output balanced is even more of a mismatch. Enjoy the single ended... that's where the synergy is....

    I haven't tried these from the balanced out of my Loxjie yet but single ended is terrific.

    All along the amp suggestion was low ohm output 0, 1 ohm etc.. That it works well with 10 ohm output is a bonus. I would not have counted on that myself.

    You can try a little slap on the left side when they cut out. That solved a similar problem for me when I over drove them. Retro solution for retro (look) headphones,

    err, you may not remember but slapping the side of old tube tv's was a diy fix practiced in every household way back when. Gently but firmly.

    Oh, don't get me wrong, I think mine look fantastic as they are. I just thought from your original pic on the campaign that it would be slightly lighter and just a tinge towards red.

    I tried Verum on my THX 789 via both single-end stock and custom balanced cables, both worked perfectly. It was a couple of hours listening session only but we've encountered no problem whatsoever.

    THX's output impedance is 0,05 Ohm as per manufacturer and 1.0 Ohm as per measurements on ASR.
