How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a full size over ear headset built for long gaming sessions with a boom mic you can tuck away, choose SteelSeries Siberia v2; if you need a lightweight over ear headphone for calls, music and everyday listening on a 3.5mm jack, choose Koss UR23ik.
• SteelSeries Siberia v2 — biggest strength: A 50mm dynamic driver setup tuned for in-game audio, plus a retractable unidirectional boom mic and in-line volume control. It's a gaming headset first.
• SteelSeries Siberia v2 — biggest trade-off: It's the bulkier, heavier pick at 1.5 pounds, and the feature set (boom mic, extension cable, USB soundcard) is aimed at desk gaming rather than pocketable listening.
• Koss UR23ik — biggest strength: A genuinely light 9.6-ounce design with a D-shaped earcup profile, in-line mic and remote, and a plain 3.5mm plug that works with laptops, tablets and gaming devices.
• Koss UR23ik — biggest trade-off: Its frequency range tops out at 20 kHz versus the Siberia's 28 kHz, and there's no boom mic — just an in-line mic for calls and voice assistant use.
• Who each is for: Siberia v2 → the desk gamer who wants one headset for voice chat and immersion. Koss UR23ik → the commuter, student or office listener who wants something light and simple.
The Siberia v2 is a closed-back, over-ear gaming headset built around SteelSeries' suspension headband design. Instead of a rigid band pressing down on the crown of your head, the suspension system uses a lightweight frame with memory-foam padding so the weight is spread out. That's the whole pitch: keep the gear light so you can wear it for hours without thinking about it. For anyone who's done a four-hour raid with a clampy headset, that design choice is the reason to care.
Audio is handled by 50mm dynamic drivers running a 20 Hz to 28,000 Hz frequency range. SteelSeries says the acoustic environment was tuned specifically for in-game sounds — footsteps, alerts, gunshots — and the earcups use passive noise-reducing foam to cut down outside distractions. Take that as a design intent rather than a promise, but it tells you what the headset is optimized for: positional awareness and voice comms, not studio monitoring.
Who should buy it: PC and console gamers who want one wired headset that handles both game audio and voice chat, and who value a retractable mic over a fixed one. Who should skip it: anyone who wants a compact, low-profile headphone for commuting, or who mostly listens on a phone. The Siberia v2 is a desk-first product, and its whole design assumes you're sitting down to play. It ships with a 2m extension cable and a USB soundcard, which reinforces that.

Koss UR23ik: Who It's For
The Koss UR23ik is the opposite kind of product: a wired, over-ear headphone that happens to include a mic. It runs a 32-ohm impedance with dynamic drivers covering 18 Hz to 20 kHz. The 32-ohm rating matters more than it looks — that's an easy load for a phone, tablet or laptop headphone jack to drive, so you don't need a separate amp or soundcard to get usable volume.
The headline design feature is the D-Profile. Koss shaped the earcup to mimic the curve of the ear rather than using a plain oval, which it says gives a better seal and therefore better noise isolation. Plush leatherette cushions sit on top of that, and the headband is adjustable. For a plastic-bodied headphone, the combination of a 9.6-ounce weight and that cushioning is the comfort argument: it's light enough that you forget you're wearing it.
The in-line remote is where it earns its keep day to day. You get an in-line microphone plus controls for answer/end calls, pause/play/skip tracks, and triggering your voice assistant. That makes the UR23ik a genuinely useful single headphone for a workday: join a call, pause a podcast, skip a track, all without touching your phone. The 3.5mm plug connects to laptops, tablets and gaming devices directly — no adapter, no dongle, no soundcard.
Who should buy it: students, remote workers, commuters and casual listeners who want one light headphone for music, calls and light gaming on a standard 3.5mm jack. Who should skip it: competitive gamers who need a boom mic positioned at their mouth and want the wider 28 kHz top end of a dedicated gaming headset. The in-line mic is fine for voice calls; it isn't a broadcast setup. As always, check the current price on Amazon rather than assuming.
• Best for gaming voice chat → SteelSeries Siberia v2. The retractable unidirectional boom mic on a gooseneck is purpose-built for it; the UR23ik's mic is in-line.
• Best for lightweight everyday wear → Koss UR23ik. At 9.6 ounces versus 1.5 pounds, it's in a different weight class for all-day use.
• Best for maximum frequency range → SteelSeries Siberia v2. 20 Hz–28,000 Hz against the Koss's 18 Hz–20 kHz.
• Best for plug-and-play simplicity → Koss UR23ik. A single 3.5mm plug into a laptop, tablet or gaming device, with 32-ohm impedance that's easy to drive.
• Best for call and media controls → Koss UR23ik. Answer/end, pause/play/skip and voice assistant access ride on the in-line remote.
• Best for hiding the mic when you're not talking → SteelSeries Siberia v2. It retracts into the left earcup, so it disappears for solo sessions.
• Best for desk-based long sessions → SteelSeries Siberia v2. Suspension headband with memory-foam padding, in-line volume, extension cable and USB soundcard.
• Best for noise isolation by design → Koss UR23ik. The D-Profile earcup seal is the specific feature Koss engineered for isolation, though the Siberia v2 also uses passive noise-reducing foam.
If I had to pick one, I'd take the SteelSeries Siberia v2 — but only because my priority is a single wired headset for game audio and voice chat, and the retractable boom mic plus 50mm drivers do that job in a way an in-line mic can't. The suspension headband and memory-foam padding are what make it livable over a long session. That said, if you're not a desk gamer, I'd steer you straight to the Koss UR23ik: lighter, simpler, easier to drive, and far better suited to a day of calls and music on a laptop or phone. Two different tools. Pick the one that matches where you actually sit.
how should over ear headphones fit
The earcups should surround your ears rather than press on them, and the headband should spread weight across the top of your head without clamping. The Siberia v2 addresses this with a suspension band and memory-foam padding; the Koss UR23ik uses an adjustable headband with plush leatherette cushions and a D-shaped cup that follows the ear's curve.
how long do over ear headphones last
That comes down to materials and how you treat them. The UR23ik is described as durable with an ultra lightweight plastic body and leatherette cushions; the Siberia v2 carries a 1-year manufacturer warranty. Cushions and cables are usually the first things to wear, so how you store them matters more than any single spec.
are over ear headphones worth it
They're worth it if you want sound isolation and comfort over long stretches, since the cups enclose your ear instead of resting on it. Both of these are over-ear designs with sound isolation — the Siberia v2 via passive noise-reducing foam, the UR23ik via its D-Profile seal. If you only listen in short bursts, a lighter on-ear style may suit you better.
are over ear headphones waterproof
Neither of these is described as waterproof, and you shouldn't treat them as such. Both are wired headphones with plastic enclosures and foam or leatherette cushions — materials that don't respond well to moisture. Keep them dry and away from rain or sweat-heavy workouts.
