If you want one wireless headset that covers console, PC and mobile gaming with spatial audio and marathon battery life, choose Corsair HS80; if you need headphones that survive being fully submerged while you swim, choose H2O Audio TRI 2.
• Corsair HS80 — biggest strength: simultaneous 2.4GHz wireless plus Bluetooth 5.2, Dolby Atmos spatial audio, and up to 65 hours of playtime over 2.4GHz (130 hours over Bluetooth).
• Corsair HS80 — biggest trade-off: it's a full over-ear gaming headset. No waterproofing rating is listed, and the design assumes you're sitting at a screen, not in a pool.
• H2O Audio TRI 2 — biggest strength: IPX8 waterproofing rated for submersion to 12 ft / 3.6 m indefinitely, plus a built-in 8 GB MP3 player so music keeps playing underwater where Bluetooth can't.
• H2O Audio TRI 2 — biggest trade-off: 6–9 hours of battery life and no noise cancelling. It's a specialist tool, not an all-day daily driver.
• Who each pick is for: Corsair HS80 for Xbox/PC/PlayStation gamers who want one headset for everything; H2O Audio TRI 2 for swimmers, paddlers and multi-sport athletes who need audio that survives water.
The Corsair HS80 is a gaming-first headset, and the spec sheet makes that obvious. The headline feature is simultaneous 2.4GHz wireless and Bluetooth — meaning you can stay connected to your console or PC over the low-latency link while your phone stays paired at the same time. If you've ever wished you could take a call or hear a notification without pulling your headset off, that's the whole point of this design.
Around that core, Corsair builds out the usual premium gaming package. Dolby Atmos gives you a three-dimensional soundstage, which matters in shooters where footsteps and directional cues are the difference between winning and respawning. The 50 mm custom drivers cover a 20 Hz–20,000 Hz range at 32 ohm impedance and 119 dB sensitivity, so they're easy to drive from a controller or a phone. There's active noise cancellation on board too, controlled with push buttons rather than touch — which I prefer, since you can find the controls by feel mid-match.
Buy it if you want one headset to handle console gaming, PC gaming and phone audio, and you hate charging things every night.
Skip it if your workouts happen in or near water, or if you need a wired fallback. Nothing in this design is aimed at swimmers.
H2O Audio TRI 2: Who It's For
The H2O Audio TRI 2 exists to solve one specific problem: music, underwater, without a phone. Bluetooth doesn't transmit through water, and H2O Audio is upfront about that — the Bluetooth 5.3 connection is for running, cycling and dry-land training with your phone or smartwatch, while the built-in 8 GB MP3 player handles everything below the surface. That 8 GB holds several thousand songs and accepts most common formats, including iTunes .M4A files. You load your music once, and the headphones stop needing a companion device.
The waterproofing is the real story. IPX8 rated, the TRI 2 can be submerged to 12 feet / 3.6 meters for an unlimited amount of time. That's a genuinely different class of protection than "sweat-resistant." The open-ear bone conduction design fires sound through your cheekbones instead of into your ear canals, so your ears stay open to traffic, lane mates and whatever is happening around you. The latest bone conduction speakers are 5 mm slimmer than the earlier TRI model, which should mean a lower-profile fit.
The bundle adds a hardshell charging case with enough capacity to fully recharge the headphones twice — a genuinely useful inclusion for a device you'll take to a pool or a lake, since it means you can top up without hunting for an outlet. Battery life runs 6 to 9 hours depending on mode and volume, with about a 2-hour charge time. Controls are touch-based, and there's no noise cancelling, which makes sense: bone conduction and active noise cancellation are fundamentally at odds, and on a bike or in open water you want to hear what's coming.
The multi-sport list is broad — swimming, biking, running, paddling, surfing, snowboarding. It's a plastic-bodied, purpose-built piece of sports gear, not a lounge headset. H2O Audio covers it with a one-year warranty on H2O Audio-branded products.
Buy it if you swim laps, paddle, surf or train in conditions that would destroy normal headphones, and you want to leave your phone in the locker.
Skip it if you mainly want a headset for gaming, calls or long listening sessions — 6–9 hours and no noise cancelling will feel limiting.
• Best for gaming and spatial audio → Corsair HS80. Dolby Atmos and 50 mm drivers versus bone conduction built for awareness, not immersion.
• Best for battery life → Corsair HS80. Up to 65 hours over 2.4GHz and 130 hours over Bluetooth, against 6–9 hours on the TRI 2.
• Best for swimming and water sports → H2O Audio TRI 2. IPX8 submersion to 12 ft indefinitely; the HS80 has no listed waterproof rating.
• Best for working out without a phone → H2O Audio TRI 2. The 8 GB MP3 player is the whole reason it works underwater.
• Best for multi-device use → Corsair HS80. Simultaneous 2.4GHz and Bluetooth lets two sources run at once.
• Best for hearing your surroundings → H2O Audio TRI 2. Open-ear bone conduction keeps your ears unobstructed.
• Best for mic quality and voice chat → Corsair HS80. It's built around a broadcast-style microphone; the TRI 2 is a listening device.
• Best for travel and charging convenience → H2O Audio TRI 2. The bundled case recharges the headphones twice over.
If I had to buy one, I'd buy the Corsair HS80 — but only because I'm the wrong customer for the TRI 2. As a general-purpose headset for gaming, calls and everything in between, the HS80's simultaneous dual wireless, Dolby Atmos, 65-hour battery and two-year warranty make it the more versatile purchase. The TRI 2 is the better product for exactly one job, and it does that job nothing else here can. So: buy the Corsair HS80 if you want one headset for screens. Buy the H2O Audio TRI 2 if you want music in the water. In my opinion, most people shopping this comparison are the former.
FAQ
You can connect it over Bluetooth 5.3 for audio, but it has no boom microphone and no low-latency 2.4GHz link, so it isn't a gaming headset. It's designed for running, cycling and swimming.
The Corsair HS80 by a wide margin — up to 65 hours over 2.4GHz and 130 hours over Bluetooth, versus 6–9 hours for the TRI 2 depending on mode and volume.
No waterproofing rating is listed for the HS80, and its over-ear design is aimed at indoor gaming. If you need submersion protection, that's the TRI 2's IPX8 rating to 12 ft. As for cost, both vary by retailer, so check the current price on Amazon before deciding.
