The press release runs to 20 specs. Up to 6 Gbps of throughput, under 2 milliseconds of added latency, 576 Mini-LED dimming zones per eye, ten infrared emitters per eye, 200 nits, 35 pixels per degree, a 120Hz eye-tracking sample rate. Pimax printed every one of those numbers at its launch blog, in the PR Newswire release, and in Road to VR’s spec rundown, which repeats the same list.

Pimax published neither figure. No weight for the headset, and no runtime for the included 16,000mAh battery pack. We checked every surface Pimax controls, live, today. The Crystal Pro product page contains a section labeled “Full Spec Sheet,” and no gram or hour figure appears anywhere in it. The company’s own compare-all-models page still lists only the Crystal Light, Crystal Super, and Dream Air, with no row for the Crystal Pro.

The product page’s comfort section is titled “Wear It Longer. Use It Anywhere.” It argues that “a rigid backstrap distributes weight more evenly than a soft one over a long session,” a claim about weight made with no weight attached to it. Meanwhile the spec list does give a complete battery rating, for the controllers: 710mAh, USB-C charging, up to 40 hours per charge. Pimax published runtime for the accessory and withheld it from the $1,399 headset.

Buyers are already asking about exactly these two

Pimax pitches the Crystal Pro as a stamina play, a wireless headset you can wear through long sessions, on or off a PC. Weight and runtime are the two figures that decide whether that pitch survives contact with a two-hour sim stint, and the announcement-day threads on r/Pimax found the gap within hours.

The weight: an 815-gram floor, and everything stacked on top of it

Pimax has already published the starting point. Its compare page lists the Crystal Light at 815 g, and the Crystal Light shares the Crystal Pro’s entire optical stack: the same 2880 x 2880 QLED + Mini-LED panels, the same glass aspheric lenses, the same 110-degree field of view at 35 pixels per degree. Glass aspheric lenses are the heavy part of this class of headset, thick glass elements where a pancake design would use thin plastic, which makes the Light’s published 815 g a floor for the Pro.

The Pro then adds hardware the Light does not have, starting with four SLAM tracking cameras plus infrared illumination and the Omnivision eye-tracking module with twenty emitters, then a Snapdragon XR2 Gen 1 board with memory and storage (the Light is tethered and has none), off-ear speakers and three microphones, the swappable faceplate mechanism for Lighthouse and MR duty, two 60GHz antenna modules that extend past the head, and the rigid backstrap with its magnetic interface hardware.

Our derivation: UltraVR estimate the Crystal Pro lands in the region of 850 to 950 grams on the head, with the Crystal Light’s published 815 g as the floor and the original Crystal’s order of magnitude as the ceiling check. The 2023 Crystal carried similar glass optics plus eye tracking and speakers, and third-party spec trackers list it around 945 g. This is inference from Pimax’s published hardware, and the company can retire it with one line of spec when it chooses.

If the estimate holds, the Crystal Pro’s head-worn mass is roughly double the Steam Frame’s complete wearable system, Frame included. The design philosophy is inverted, and that is the fair counterweight to the chart. Valve puts a 185-gram visor on your face and hangs its 21.6Wh battery at the back of the strap as a counterweight. Pimax keeps its energy off your head entirely: nothing inside the visor, power arriving by cable from the pack. Both are answers to the same problem. Pimax’s answer concentrates more grams on the face than anything in this comparison except headsets that also carry their power there.

The pack itself enters the arithmetic wherever you put it. A 16,000mAh lithium brick sits in the neighborhood of 300 g by the standards of consumer power banks, and Pimax has not said whether it clips to the strap, rides in a pocket, or is meant to sit on the floor. In a pocket it costs your neck nothing; on the strap it turns an 850-gram headset into a 1.15-kilogram wearable.

The battery: getting from 16,000mAh to hours

Milliamp-hours only become hours once you divide by a voltage and a draw, and Pimax has published neither. Standard lithium cells run at 3.7 V nominal, which makes the included pack roughly 59 Wh (a 3.85 V chemistry would give about 62 Wh). For scale, that is 2.7 times the Steam Frame’s 21.6Wh cell and about four times the Quest 2’s.

The estimate hinges on the draw, and there are two anchors for it. The Crystal Pro runs the same Snapdragon XR2 Gen 1 chip as the 2019 Quest 2. Meta rates the Quest 2’s 3,640mAh pack (about 14 Wh) at two to three hours, which works out to roughly 5 to 7 watts while driving 3.5 megapixels per eye and doing all compute on device. The Pro asks the same chip family to drive 8.3 megapixels per eye, 2.4 times the pixels, plus four tracking cameras, eye tracking, and a Wi-Fi or 60GHz radio. Display and backlight power track pixel throughput closely enough for this purpose. A central draw estimate of 12 to 22 watts during streamed play is the band those anchors support.

The original Crystal’s owners give a real-world cross-check. In a 2024 test posted to the OpenMR forum, an 18-watt USB supply slowly lost ground over three hours of sim racing with eye tracking enabled, and roughly held level with eye tracking off; a 65-watt source charged the headset mid-session. Pimax’s own support documentation recommends a 40W+ charger for sessions of “10 hours or more.” Both points sit on the same line this panel class draws 15 to 25 watts under load.

For c0mander5’s question, the answer works out to roughly 3 to 4 hours of streamed play per pack charge, stretching toward 4.5 at 72Hz over Wi-Fi and toward 2 at 120Hz with the 60G AirLink working hardest. That covers one long endurance split but not two, and the pack’s recharge time is unspecified too: refilling 59 Wh takes roughly three to six hours depending on the charger feeding it. Back-to-back race days turn on charging logistics or a spare pack, and Pimax has not said whether the pack is swappable. The December 2024 Crystal Air concept pitched interchangeable packs. The Crystal Pro materials describe one included pack and stop there.

How the power flows

Set against the Steam Frame, the two designs are different bets. The Frame carries its 21.6Wh on your head inside a 440-gram total, and Valve has not published its hours either, a gap we worked through in our September piece on the Frame’s battery. The Pro carries roughly 2.7 times that energy in a pack you don’t wear, in exchange for a visor that our estimate puts at twice the Frame’s total mass. The buyer’s question is which end of that trade their neck and their session length care about, and right now only the Frame comes with published numbers.

The $1 reservation, judged against Pimax’s record

The reservation itself is low stakes: $1, credited against a $20 headset discount or $50 off the $1,899 AirLink bundle, and non-refundable per Road to VR’s read of the store terms. Pimax’s track record is the less reassuring part. Pimax announced the Dream Air in December 2024 for May 2025 and shipped it about a year after that promised date. The ringless controllers announced in early 2025 never shipped and were re-announced in new form this week. Specs for Pimax products tend to firm up late, and this spec sheet is showing the same behavior on day one.

• If you have reserved, the money at risk is a dollar, and the estimates above give you a realistic floor to hold the final hardware against. A shipping unit that lands at 815 g with four-hour sessions would beat our expectation.
• For anyone weighing a Steam Frame purchase email against a Pro reservation, today’s information is not enough to decide. The Frame-vs-Pro comparison turns on grams and hours, and neither is published for the Pro. Wait for Pimax to complete the sheet or for the first hands-on measurements, whichever arrives first.
• If you write to Pimax (its staff post as Pimax_Daisy on r/Pimax), the four questions that matter are the ones this piece could not answer: headset weight with strap and interface fitted, runtime at 120Hz streaming, where the pack is meant to ride, and whether packs are swappable for back-to-back sessions.

“Wear It Longer” is the line on the product page, and Pimax has not attached grams or hours to it. The two numbers exist somewhere inside Pimax’s engineering builds. Every other figure from the Frontier event was ready for the stage. These two were left off, and they are the ones you feel the moment the headset goes on.
