Yes I know that sound is bad. Its only on my right ear. What about you?
Have you tried connecting the headphones via an extension cable directly to your PC?
when I do that the noise is gone. I think there’s something going on with the HMD itself
Regarding positioning of the speakers. Did you see the email VR Ears sent out today?
I’ll paste the important bits here
VR Ears are very different than headphones and so is the installation process, we can compare first time setup to that of early consumer drones or high-end speaker monitors. VR Ears does not press against your head and cannot be quickly thrown on and function well. They must be installed, positioned properly, and can take some time to optimize. We wanted them to feel firmly attached to the headset, like they are a part of it, but users could upgrade their next headset with VR Ears far into the future.
This is an example of the incorrect setup position; we can clearly see the clip is placed much too far back on the strap and the speaker is way below where your ear would be. (They think we’re idiots)
Correct setup position, VR Ears is on the 3rd click position and adjusted. LSToast: “they sound way better, comparable to Index but I would say a little lacking on bass…they sound amazing”
We cannot stress enough the importance of closely following the instruction manual and/or watching the video tutorial. The “sweet spot” for optimum audio is fairly narrow, and it is important that you make sure that the center of the speaker driver is positioned directly over your ear canal.
Another important point is that VR Ears, as with most high-performance speakers, have a “burn-in” period and after 40 hours of use the acoustic performance will improve dramatically , especially the bass response ! If you wish to speed up the process, we recommend playing this track on medium volume each day for 1 week:
I wonder how much of this would apply to the DMAS? What’s this nonsense about burn in?

Low no surprise they are quite testy with ppl when they don’t get a positive response. They cheaped out on adapters.
I heard some nonsense about burn in.

Cool thanks Timo. If I get some ambition will start experimenting as well. Am curious if pimax didn’t add any dampening material. That could explain the lack of bass.
The odd noise your getting is concerning. I am not experiencing it so suggests maybe some kind of noise maybe on 5v rail or receiving interference from something. Or could be a defective dmas set.
That burn in Video they suggest is 2 hours long. They recommend runing that for 3 weeks every day? 
and magically your bass will sound better?

Yeah no just plain nonsense. Unless headphone and speaker companies do this in the factory prior to selling.

lol after some digging no i don’t have the world’s smallest screwdriver and I don’t have a backerbox. Looks like I’ll have to install it a bit later after paying a visit to my brother’s house. Retail shops are still locked down here so buying one is abit of a task at the moment.
Hey pimax, include a tiny screwdriver in the box next time! Not everyone has a screwdriver this tiny! 
for a $100 usd accessory it’s not too much to ask!
But small issue, worst case is borrowing one from my neighbours.

Ok here is my impression,
Build quality is top notch, premium material, holds comfortably in the hand, it is a great set of precision set. Would recommend this screwdriver set. 
ok DMAS, stereo whine, sounded similar to like when a car stereo was not grounded properly, once there are sounds being played it would cover over this whine, but when in complete silence, this is very noticable and i would say it’s unacceptable for any, and i mean ANY headphone to exhibit this. Sound quality is very acceptable and sounded good quality with a good sound stage. Bass is very subtle, I’m not a bass man so for me I wouldn’t feel this is a big issue for me.
I liked the off ear option, felt much more comfortable and cooler.
But the stereo whine, how does this get past the QA team?? this is beyond my understanding.
as a point of reference for my impressions, I own a set of sennheiser momentum 2.0 and a sennheiser hd6xx.
This just my quick fast impression, I felt the dmas is good enough, if it can loose the stereo whine.

I’m lucky. I don’t have any whine. I wonder if some people are having a grounding issue or there’s some sort of electrical noise on the USB line. The DMAS is acceptable, but Sennheiser equipment is in another league.

I’m suspecting this as well. but none of the headsets I’ve used prior has stereo whine this excessive.

the problem with the constant beeping or whistling … I could not solve until now.
The new index loudspeakers also have it.
Maybe a little bit quieter.
When I connect the valve Index … I don’t have this problem. it’s only at Pimax.
the problem could also be with the Pimax 8KX.
Maybe a bad production?
it’s crazy.
but the KDMAS index mod will be great for me.
only the constant sound in silence is terrible.

They never done before. So I ask them and they valutate 8$ plus shipping. Now I’m waiting to receive.
It way a idea I had before receive the dmas, because I was sure the problem of sound because of distance from the ear

My DMAS are arriving today, if I get the high pitch whine I will try adding a ground loop isolator to see if that helps.

The sound is coming from both speakers. I tried connecting them to my PC via an extension cable like you proposed, and indeed the noise disappeared. That would imply the noise comes from the HMD itself or maybe some interference with the cable. But if thats the case, why do you only have the problem with one speaker? Weird…
Anyway, Pimax support agreed to send me an replacement DMAS. As soon as I get it I’ll post if that improved anything.
