How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, over-ear gaming headset built for long sessions at your desk, choose SteelSeries Siberia v2; if you need a wireless, open-ear companion for running, cycling and outdoor workouts, choose HAKII Light 2. These two have almost nothing in common except that both sit on your head — and that's exactly why the right pick comes down to where and how you'll use them.
• SteelSeries Siberia v2 — biggest strength: full-size over-ear design with 50mm dynamic drivers, a retractable unidirectional mic and an in-line volume control — a classic wired gaming setup. Trade-off: it's wired, so you're tethered to your device with a 2m extension cable, and it's a 1.5 lb full-size headset.
• HAKII Light 2 — biggest strength: open-ear air-conduction design at just 26g with Bluetooth 6.0, a 16-hour battery and an IPX5 rating — built for movement. Trade-off: no wired jack at all, and open-ear audio deliberately lets outside sound in.
• SteelSeries Siberia v2 is for: desk-bound gamers and anyone who wants a boom mic and corded reliability.
• HAKII Light 2 is for: runners, cyclists and gym-goers who need to hear traffic and their surroundings.
• Quick call: pick SteelSeries for voice chat and immersion; pick HAKII for outdoor awareness and freedom from cables.
The Siberia v2 is the archetypal gaming headset, and its design tells you that immediately. It's an over-ear, closed-back headset with 50mm dynamic drivers running a 20 Hz–28,000 Hz frequency range. In plain terms, that's a full-size acoustic chamber — the kind of hardware that gives you a sense of weight and space in game audio. SteelSeries says the acoustic environment was tuned specifically for in-game sounds like footsteps, alerts and gunshots, and the passive noise-reducing foam in the earcups is there to push the outside world back so you can focus on the mix.
The physical design is the other half of the story. The Siberia suspension headband is a lightweight, self-adjusting band with memory-foam padding — it rests on your head rather than clamping down, which matters when a session runs for hours. The microphone is the standout practical feature: a unidirectional pickup on a gooseneck boom that retracts into the left earcup when you're not talking. If you've ever wanted a mic that's there for a raid and invisible for a solo campaign, that's the appeal. Volume control sits in-line on the cord as a push-button, so you can ride levels without alt-tabbing into system settings.
So who should buy it? Anyone whose primary audio happens at a desk — PC gaming, voice chat, watching video on a laptop. It's also a sensible fit if you dislike charging things: it's wired, powered by your device, and it ships with a 2m extension cable so you can move around a bit. Who should skip it? If your listening happens while running, cycling or lifting, this is the wrong tool. It's a 1.5 lb over-ear headset with no wireless connectivity — it isn't built to survive sweat or to let you hear a car coming up behind you.
The HAKII Light 2 is a different species entirely. It's an open-ear, air-conduction headphone — meaning the drivers sit outside your ear canal and project sound toward it rather than sealing you in. The result is that your ears stay open to the environment while you listen. For outdoor training, that's not a compromise; it's the whole point. Combined with the 180° Ultra-Bright Beacon String and its three lighting modes, HAKII has clearly designed this for visibility on night runs and early-morning rides.
The audio hardware is deliberately bass-forward: 16mm dynamic drivers, 22 ohm impedance, 135 dB sensitivity and a 20 Hz–20,000 Hz range. HAKII calls the technology BassBoost and describes an oversized diaphragm for deep low-end. Practically, that's a tuning meant to cut through wind and traffic noise — the kind of sound that keeps a playlist motivating on a long jog.
Everything else about the Light 2 points the same direction. It weighs just 26g, with a flexible titanium frame and soft silicone that's meant to stay put without irritation. It's IPX5 rated, so sweat and rain splashes are covered. Connectivity is Bluetooth 6.0 with a 10-metre range and dual AI noise-cancelling microphones for calls. Battery life is up to 16 hours with a 1-hour charge time. There's no headphone jack at all — it's wireless-only, controlled by buttons and an app.
Buy it if you want audio while you move and you refuse to be sealed off from the world. Skip it if you need a boom mic for team voice chat, want wired latency-free monitoring, or prefer the deep isolation of over-ear cups. Open-ear design is a feature, not a flaw — but it's a feature that only pays off outdoors.

If I had to pick one, I'd buy the SteelSeries Siberia v2 — but only because my listening happens at a desk. In my opinion it's the more versatile of the two indoors: a real boom mic, volume control on the cord, closed cups, and no battery anxiety. That said, if your audio life happens outdoors, I'd take the HAKII Light 2 without hesitation. The open-ear design, 26g weight and beacon light make it the safer, more comfortable choice for running and riding, and its 16-hour battery covers a week of workouts. Decide where you'll actually wear them, and the answer is obvious.
FAQ
You can connect it over Bluetooth 6.0, but it's a compromise. There's no boom mic, so calls rely on the built-in AI noise-cancelling microphones, and the open-ear design won't isolate game audio the way closed cups do.
The HAKII Light 2. It carries an IPX5 water-resistance rating for sweat and water splashes, and its 26g open-ear titanium frame is built for movement. The Siberia v2 is a 1.5 lb wired over-ear headset with no water-resistance rating.
Both are sold on Amazon, and prices move around, so check the current price on Amazon before you commit. Don't let that be the deciding factor, though — one is a wired desk headset and the other is a wireless outdoor headphone. Pick the one that matches where you'll wear it.
