Heads up: the specifications for the headphones is missing on the pimax store!

This is a product for audiophiles, and DEAR GOD they will want to know what the specs of the drivers in the earphones on.

@SweViver @PimaxUSA @pimax @PimaxVR

Example specs readout for headphone drivers:

Type – A description such as “closed-back dynamic” or “active noise-cancelling.” This may be the first spec you want to look at when selecting headphones because it indicates the style or function of the headphone.

Driver Diameter – Headphone sound quality depends to a great extent on the size of the diaphragm, which is indicated by the driver diameter: the larger the diameter, the better the sound quality tends to be. Most drivers for earbuds are 13.5–15.4 mm in diameter, with those for canalphones being 8.8–12.5 mm. Over-ear and On-ear headphone drivers lie in the 30–53 mm range.

Magnet – Sound quality can also be improved by the performance of the permanent magnet in the magnetic circuit. These magnets are often made of ferrite or cobalt, although sometimes more exotic material is used for stronger magnets.

Voice Coil – The voice coil fulfills a key role in converting electrical signals into sound. For better sound quality, voice coils are made of a variety of material besides ordinary copper wire, including PCOCC (Pure Copper by Ohno Continuous Casting) and Hi-OFC (a class of oxygen-free copper).

Frequency Response – The range of frequencies that the headphones can reproduce, from the lowest bass frequency to the highest high frequency, expressed as a numeric value. Although the typical audible range is 20–20,000 Hz, inaudible higher frequencies do affect the listening experience.

Maximum Input Power – Maximum input indicates the maximum supported power supply for the headphones, measured in mW. This is the peak instantaneous power that may be supplied. It should not be misunderstood as meaning that headphones rated at 2,500 mW (for example) can be continuously powered at 2,000 mW. Moreover, larger values are not necessarily better. As long as the value matches or exceeds the player’s maximum output value, any value is acceptable.

Sensitivity – The level of sound pressure produced by the headphones in response to a 1 mW signal. Measured in decibels per milliwatt (dB/mW). At a given input volume, headphones with greater sensitivity will produce a louder sound. A difference of 3 dB/mW or more is generally considered audible to most listeners.

Impedance – As a value indicating the degree of headphone electrical resistance, this specification mainly represents the voice coil resistance but also includes cable resistance. Measured in ohms (Ω). Choosing low-impedance headphones for low-voltage portable audio players ensures better efficiency.

Weight – This indicates the weight of the headphones and usually does not include the weight of the cable. This may be an important factor to consider for comfort, especially during extended use.

Cables – Cables come in various thicknesses and lengths to suit different listening needs. Cables are generally made of 99.5% pure copper wire, but for more efficient signal transmission they may be produced with exceptional material such as oxygen-free copper—whether Hi-OFC, PCOCC (Pure Copper by Ohno Continuous Casting, 99.996% pure copper), or other kinds. Additionally, the cable sheath may be cloth-wrapped or constructed of highly elastic elastomer to help prevent tangling and reduce “touch noise” when the cable is touched.

Active Noise Reduction – This is only provided for headphones with active noise-cancelling components. This indicates the amount of noise reduction at certain frequencies. This is measured in dB. Higher numbers indicate more noise reduction.

Connector – Plugs into the headphone jack of AV equipment or portable audio players. Comes in two main formats: standard (6.3 mm) and mini-plug (3.5 mm). Many headphones are equipped with a 3.5 mm mini-plug and include a 6.3 mm adapter.

Accessories Included – This is a list of all the additional items that are included when the headphones are purchased. This may include such things as additional cables, adapters, carrying case, batteries and so on. Checking this list is very important to ensure that you’ll have everything you need to use the headphones the way you intend. For example, if you plan to use the headphones with a professional audio device that has a 6.3 mm input and the headphones are terminated with a 3.5 mm connector, you’ll want to make sure that a 3.5 mm to 6.3 mm adapter is included.

Generally speaking you want as flat of a frequency response as possible. True to the devs intention. No cosmetic bass enhancements or stereo field enhancements etc, or atleast not without the option to turn them off.

Signal to noise ratio is also super important. Basically the wider the gap between the sound being replicated and the noise from current that is used to carry the signal.

It’s definitely true that those above ear headphones will require the drivers in them to be tuned differently than over ear headphones because they are in fact speakers and not headphones. Bass is a real concern but hopefully the mm of the drivers is nice and large.

Another important aspect is grounding the signal, which I hear some hmd’s did not do, hence they have noise with their signal.


Yep & atm no specs for off ear as well.


Can you please show us the infos you listed for the audio solutions on the Quest, Rift, Rift S, Vive, Cosmos, Index, Reverb, or Odyssey?

At least one of these data points for one of these headsets?

Thought so.

That said, I also really would like to know SOME more details on the Pimax audio options. E.g., whether the Deluxe version still has the Standard speakers included for the times you do not want to cover your ears.


For Valve Index at least the full product page on their website has
“ Audio

Built-in: 37.5mm off-ear Balanced Mode Radiators (BMR), Frequency Response: 40Hz - 24KHz, Impedance: 6 Ohm, SPL: 98.96 dBSPL at 1cm.

Aux Headphone Out 3.5mm


I hope you realise that these numbers tell nothing about how good the sound in the end actually is (in the case of the Index, the sound is great, something I know from reviews and my own experience).


“Audiophile” is a big call to make by pimax. They won’t be audiophile for $100.
Sennheiser HD600’s range is often considered at the lower end of audiophile gear. I don’t consider the lower ranges (than the 600’s range) audiophile at all as most don’t.
They may use the term for marketing but there’s just no way they will be audiophile range.
That doesn’t mean they won’t be relatively good for a VR headset. Real audiophile would add too much cost for any VR hmd. And real audiophiles will already have headphones they can use instead.
Pimax should steer clear of the term.


If your selling 200$ headphones, specs.

Unless they are called for example “Beats by Dre”. Check the “specs” for these supposedly 400 USD headphones (Wireless Headphones and Earbuds - Beats) :wink:




Hmmm… Koss is a big brand though maybe not a great brand. :thinking::vulcan_salute::sparkles:

So is Schneider :grin:

Beats are crap, I sometimes literally lol at people on the street wearing them out of pity. Can‘t barely hide it.
Apart of the fact that they don‘t know what their money is worth the have no freaking clue what sound is as long it‘s…red…or…blue with hip stickers on it😂


I agree, but I don’t necessarily need to be as audiophile in VR as I am in music. (Still love my Genelec 1030A, HD650 and UE11pro) But the sound should not be bad either. Pretty confident though that you can’t go horribly wrong with any sennheiser at any pricerange. They usually deliver a fair bang for the buck. (The former marketing manager is a close friend of mine for many years, so if Pimax needs contacts I may be of help)

Anyways…they need to call it something to sell.
And today, where most people are listening to 2:30 minutes crap songs produced on iPads at 256 kb Mp3 through 30$ chingchang bluetooth speakers…who knows…it’s probably even just to call it audiophile and I’m just old :slight_smile:


Tbh those who want to listen to audiophile level music in VR will probably be better off popping the earphones off the head-strap and using the audiophile level headphones they already own.

For VR we need drivers for immersion, that means they have to be able to do a reasonable world reproduction, explosions, bird tweeting and an all over reasonable from a solid bottom to a precise high… and all within 100$.

It’ll be interesting to see what they come up with.


And with canceling out outside noise pollution that will ruin immersion.


Christ mate you should ask for display details too. Like contrast ration, brightness etc.

Vagueness is the name of the game.

It’s strange Pimax has never shown the Deluxe Headstrap at either PD1 or PD2. All we’ve seen so far is a pre rendered picture.

Pimax doesn’t inspire confidence in any of its line up, like the MAS with missing foam. I just wouldn’t bother having a PD at all until I had products in my hand and manufacturing was in full production.

There’s no point rushing into a brick wall of empty promises or promises that need drastic alterations months down the line. But hey that’s just me.

I agree. I have HD660S’s and Verum One’s and tend to only use them for music. I’m happy with a reasonable quality sound on VR hmds and don’t expect anyone to sell audiophile attached to a hmd.

This really gets my goat. I can’t stand that kids are using the most crap sampled MP3s through $10 speakers. Do they even have hearing? I really don’t like the dumbing down of the HiFi world where crap equipment is being marketed as high end because the low end has plunged to such terrible depths. When I was a boy…haha so you can tell I’m old.
(Old man waving his stick around and shouting) These young people need a proper education, pffft to these fandangled bluetooth tin crackling poor excuse for a speaker, and don’t get me started on people who put thousand inch woofers in their car!
Do not go gently into this night…


Their (parents) money goes to hyped rapid smartphones that can play Fortnite instead of sound quality. Most songs are autotuned and just sound painful to me as well.

It’s probably the equivalent of our old guys listening to classical violins and the Beatles on turntables, and snorting at (e-)guitars, good metal and rock.


I listen to classical violins, get season tickets every year to the Australian Chamber Orchestra. I listen to The Beatles on turntable too. Where’s my walking stick?
Love good metal and rock too. Have you listened to Tool’s new album? Sensational stuff.
No auto tuned packaged pop though, I wouldn’t abuse my ears with that stuff.


Deluxe headphone strap should be FREE, it looks like it is part of the stretch goal.
