DMAS audio review

I find that what it the DMAS lacks in bass it makes up for in spatial audio. It sounds like the sounds are coming from around me.


This doesn’t resolve the issue, I have Voicemeeter and even with +12 db on Bass (max) there is still no bass and at +12 db the speakers are vibrating to the point that there is speaker distortion present. Sure, if I cup my f’ing hands around the DMAS and my ears there is bass (gee, this is such a great suggestion! I can just f’ing play anything like this perfectly!) but this is such a ridiculous proposition that it doesn’t even need further mention.

Putting the KDMAS cushions on the DMAS and KDMAS still sounds better, with less distortion because of the closed speaker back design.

DMAS was rushed. Proper DMAS could be accomplished if one could tilt the speaker arms closer to ones ears like Index / G2 / VP2 speaker arms. But that’s beyond the ability of genius Pimax engineers who simply retained KDMAS speaker arms as the solution.

I’m seriously disappointed that these were even released in this state. I’m out $100 because of Pimax’ incompetence. Like this isn’t f’ing rocket science. The problem is the speakers are too far from the ears to be of open ear design. We are literally talking about a flimsy $2.00 plastic hinge that needs to be placed where the speakers screw into the headstrap. See: Vive Pro 2 speaker arms. See: Index and Reverb G2 speaker arms.

That everyone here who has tried the DMAS and finds the lack of bass and mids rendering the solution unusable means that Pimax engineers had to have similarly come to the same conclusion but released this garbage anyway. That we cannot get a refund is unacceptable and someone ought to be fired over this. Whomever made the decision to release the DMAS in this state deserves to be fired. Full stop.

Pimax, you made an unacceptable product, allow us to return it to maintain good faith.


I understand and I’m with you… now I order KDMAS cushions for 8$

I will try to find a better solution.

New or different design to change the speaker spacing.

Then new speakers and maybe new external amplifiers.

The first spare parts for my job are arriving today and I will start my job.

I can create designs myself and print them with a 3D printer.

Maybe it will be fine. Stay tuned.


my problem was no or bad audio coming out unless the right earpiece was mounted upside down – but even that wasnt consistent. lots of sound/sound quality issues (though not the high pitch noise people here are complaining about) . sounds great now , wish there was more bass after using the kdmas for so long but i’ve gotten used to it now.

Yes it is a great suggestion just replace cupping your hands with these minus the cushions.

Your Welcome. Just need a 3dprinter or purchase a printed set through a print firm.

See my post to vulcan. GrodenVR has already created a solution that should work. Originslly for the Kdmas.

Amp wise there are some usb powered amps on Amazon. For under $20 cad.

Here is link to a topic where I had bought some bmr speakers ti experiment with. But have yet to get back to playing with them. Here is the link for 1 amp there.

I too have the high pitched sound Timo.H1 and Gsmith described. It appears as soon as the HMD is powered up, and it isnt affected by volume setting. I contacted Pimax support, hope they can help.

Apart from that, I am actually very satisfied with the DMAS. The highs and mids are pretty good, bass could be better, but its nowhere as bad as some described it in this thread.
I play with a Volume setting between 40 and 50%, so loudness is also good with my DMAS.
Now I only need to get rid of that sound…


I think we may need to compare system setups. And no we really shouldn’t need to.

So if we can maybe compare Mobo, gpu, psu for example we might find some commonalities between.

I am using a corsair sfx on an Asus b450-i aorus mobo & Zorac mini 1080ti. No extta Noises.

Any chance of buying a pair of those 3d printed parts and shipping it to the Netherlands?

If so, I will make the STL files available to everyone free of charge.

You can then print it yourself or have a friend print it for you.


So now I’ve got the new boxes.

But there doesn’t seem to be a big difference.

The new boxes sound very good. I have the feeling the sound is a little deeper. but only minimally.

It is not worse than DMAS.

I tested both with an amplifier. It gets louder … but somehow I don’t like the bass yet.

But first I installed a box.

will continue testing.
next i will install the other box as well and then i will change the distance to the ears :ear:.


In the thread I linked to you earlier if you goto first post. Checkout the reddit link. Iirc the op on reddit talked about using some wool or batting of some sort to improve bass.

Here is part of his post

Link for ease


Yes I know

two things need to be changed.

the distance to the ears should be about 5 to 6 mm closer.

And there has to be some insulation.

I’m working on it right now.


I am very optimistic after a few tests …

I think this will be very good.
better than the original DMAS I think.


Are you modding the Kdmas or is this the Dmas? I recall you bought the 6Ohm BMR speakers Valve/G2 and presumably pimax is using.

If the kdmas to dmas mod do yiu have the tone issue you reported on the DMAS?

If this is the DMAS is it missing the dampening material?

you can order just the cushions?

First try the audio was low, went in to windows and maxed it out and now the volume is fine, think the audio is good, better then DAS, bass is so so, if you cup them it is better.

And dont get why not Pimax add a driver that say Pimax DMAS or something like that and then mic Pimax mic or something, also add audio settings in pitools/experince :slight_smile:

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?
