How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a cheap, phone-powered taste of big-screen 3D movies and mobile games, choose Mryzzsf 3D; if you need a real wired gaming headset for PC or console play with voice chat, choose Corsair HS35.
These two products share almost nothing except the word "gaming" in their marketing. One is a passive plastic shell you slide a phone into. The other is a proper over-ear headset with drivers, a mic and a cable. Comparing them is really about comparing two different hobbies — solo movie immersion versus talking to your squad while you play. Here's how I'd sort them out.
• Mryzzsf 3D — biggest strength: turns a 5.0–7.0 inch smartphone into a stereoscopic viewer with adjustable pupil distance and focal distance, plus a 95–120° field of view.
• Mryzzsf 3D — biggest trade-off: it has no battery, no processor and no audio of its own. Everything you see and hear comes from the phone you supply, and it only fits phones within that size window.
• Corsair HS35 — biggest strength: a genuinely multiplatform wired headset — one 3.5mm plug covers PC, Mac, PlayStation, Switch and more — with 50mm neodymium drivers and an omnidirectional mic.
• Corsair HS35 — biggest trade-off: it's wired only, it's audio-only, and it does nothing for VR or 3D content. There's also no active noise cancellation, just passive over-ear cups.
• Who Mryzzsf 3D is for: someone who already owns a compatible phone and wants to sample VR-style movies and simple mobile games without buying a standalone headset.
• Who Corsair HS35 is for: a PC or console player who needs one headset that works everywhere, stays comfortable for long sessions and handles team chat.
The Mryzzsf 3D is a phone holder shaped like a headset. That sounds dismissive, but it's actually the point: the design offloads all the computing to the smartphone you already carry. The shell is built from ABS and PC plastic, measures roughly 22.5 x 12.5 x 12 cm and weighs 430g, and it holds any phone between 5.0 and 7.0 inches — the list covers recent iPhone and Galaxy models and plenty of older ones too.
What it does best is the optical side. The headset gives you both FD (focal distance) and OD (object/pupil distance) adjustments, and that matters far more than it sounds. If the lenses don't line up with your eyes and the screen, you get a blurry, cross-eyed mess within minutes. Being able to dial in pupil distance and focal distance — including unilateral myopic alignment, per the specs — is the difference between a two-minute novelty and something you'll actually use for a full movie. The stated 95–120° field of view is generous for this category, and the adjustable head strap and soft nose piece are there to keep the 430g from digging in.
The bundled remote controller is the other practical touch. It pairs with the phone and gives you play/pause and volume up/down without pulling the phone out of the shell — which, trust me, you do not want to be doing mid-film. The package also includes a cleaning cloth and an English manual, and the manual matters, because the alignment routine (phone placed horizontally, centered on the line, then adjust the two dials) is not something you'd guess correctly on the first try.
Who should skip it: anyone expecting true room-scale VR, motion tracking or built-in audio. There is none of that here. If your phone is smaller than 5.0 inches or bigger than 7.0 inches, it simply won't fit. And if you're after competitive gaming audio, this is the wrong product entirely — it's a viewer, not a headset in the audio sense.
Corsair HS35: Who It's For
The Corsair HS35 v3 is the opposite kind of product: a self-contained wired gaming headset that does one job — game audio and voice chat — and does it across basically every platform you own. The universal 3.5mm jack is the headline feature for me. One connector covers PC, Mac, PlayStation, Nintendo Switch, Xbox and more, which means you stop juggling separate headsets per device. Plug it into the controller, plug it into the laptop, done.
The audio hardware is the real substance. Custom-tuned 50mm neodymium drivers are large for this class, and the specs list a 20 KHz frequency response, 32 ohm impedance and 113 dB sensitivity. The 32 ohm impedance is the number that matters most in practice — it's low enough that a controller's headphone jack or a laptop's onboard audio can drive it properly without a separate amp. That's exactly what you want from a headset designed to plug straight into whatever you're playing on.
Comfort is the other half of the design story. The HS35 v3 uses an adjustable floating headband rather than a fixed sliding band, paired with soft fabric earpads. Fabric breathes better than pleather over a long session, and the floating band spreads weight instead of creating a hot spot on top of your head. At 8.16 ounces it's light enough that marathon sessions shouldn't be a problem. The over-ear, round earcups are plastic-bodied in white, so it's a clean, understated look rather than an aggressive gamer aesthetic.
Who should buy it: a player who splits time between a console and a PC and wants one wired headset for both, values comfort over RGB flash, and needs a mic for party chat. Who should skip it: anyone who wants wireless freedom, active noise cancellation, or — obviously — anything VR or 3D-related.
Side-by-Side: Which Should You Choose?
• Best for 3D movies and mobile VR → Mryzzsf 3D. It's the only one of the two that does it at all.
• Best for actual game audio → Corsair HS35. 50mm neodymium drivers versus no drivers whatsoever.
• Best for voice chat and team play → Corsair HS35. The omnidirectional mic and earcup mute button are built for it.
• Best for multiplatform flexibility → Corsair HS35. One 3.5mm plug covers PC, Mac, PlayStation, Switch and more.
• Best for long-session comfort → Corsair HS35. Floating headband plus breathable fabric earpads at 8.16 ounces.
• Best for sharing with family and friends → Mryzzsf 3D. Hand it around and let people take turns; the specs pitch it as a gift for kids and adults.
• Best for phones-only, no console or PC → Mryzzsf 3D. If your gaming life lives entirely on a smartphone, this is the more relevant buy.
• Best for a single do-everything purchase → Corsair HS35. It's the one that plugs into more of your existing setup on day one.
If I had to pick one, I'd buy the Corsair HS35. In my opinion it's the more useful object for more people: it works with the hardware most gamers already own, it produces its own audio, and it has a mic you can actually talk through. The Mryzzsf 3D is fun and clever, but it's a phone accessory — no phone, no experience — and it asks you to already own a specific size of device. Buy the Mryzzsf 3D only if 3D movie viewing on your phone is genuinely the thing you're chasing. Otherwise the HS35 is the safer, more versatile call. Whichever way you lean, check the current price on Amazon before deciding, since that's the one variable that can flip this recommendation.
FAQ
Only if your phone has a 3.5mm headphone jack or you use an adapter, since the HS35 v3 is a wired headset with a 3.5mm plug. It's designed primarily for PC, Mac, PlayStation, Switch and Xbox.
It supports phones from 5.0 to 7.0 inches. If your phone falls outside that range, it won't fit properly, and the pupil-distance and focal-distance adjustments can't compensate for a screen that's the wrong size.
Based on the designs, the Corsair HS35 — it uses an adjustable floating headband and soft fabric earpads and weighs 8.16 ounces. The Mryzzsf 3D relies on an adjustable strap and nose piece to manage its 430g, which is heavier on the face.
No. The Corsair HS35 lists noise control as none, so it relies on passive over-ear isolation. The Mryzzsf 3D has no noise control feature at all.
