If you want the adapter that also covers legacy Xbox 360 headsets and plugs into Windows 10 as well, choose Microsoft Xbox One; if you need an adapter built for the full spread of modern Xbox controllers with on-board volume, mic mute and game/chat balance controls plus a stated multi-year guarantee, choose OLCLSS Headset Adapter.
• Microsoft Xbox One — biggest strength: It does the one thing the OLCLSS adapter doesn't even try to do. It bridges legacy 2.5mm chat headsets and Xbox 360-era gear into the Xbox One family, and it's listed as compatible with Xbox Series X, Xbox One and Windows 10.
• Microsoft Xbox One — biggest trade-off: It's the older, bulkier design (5.8 x 5.6 x 1.9 inches, 1.76 ounces), it has a documented incompatibility list, and Microsoft's own note says it's already bundled with new Xbox One stereo headsets — so you may not need to buy one at all.
• OLCLSS Headset Adapter — biggest strength: A tiny, current-generation puck (4.1 x 3.1 x 0.83 inches) that fits Xbox One, One S, One X, Elite 1, Elite 2, Series S and Series X controllers, with dedicated volume up/down, mic mute and game/chat balance controls built in.
• OLCLSS Headset Adapter — biggest trade-off: It's a third-party accessory from an unfamiliar brand, and its compatibility story stops at the controller — there's no legacy 2.5mm or console-side audio path mentioned.
• Who each is for: Microsoft for the buyer with older headsets, a Windows 10 setup, or a specific need for legacy chat support. OLCLSS for the buyer with a modern Xbox controller and a 3.5mm CTIA headset who wants controls at their thumbs.
The Microsoft Xbox One Stereo Headset Adapter is the original answer to a real problem. When the Xbox One controller launched without a headphone jack, this little block slid into the controller's expansion port and gave you a 3.5mm socket for chat and stereo game audio. Microsoft's own product notes make a point that's easy to miss: many new stereo headsets designed for Xbox One already ship with this adapter in the box, so if you bought a headset recently, check the packaging before you buy anything.
Where this adapter genuinely stands apart is legacy support. A stereo headset with a 3.5mm CTIA-standard plug gets chat and stereo game audio straight through the controller — no cable to the console required. A microphone is required for chat, which is worth repeating because people buy this thing expecting audio only and then wonder why nobody hears them. For Xbox 360-era headsets, the path is different: game audio comes from the console's S/PDIF port or from your TV/receiver over RCA, and chat audio comes through the 2.5mm cable plugged into the adapter using the included audio jack adapter cable. That's a genuinely useful trick for anyone with a drawer full of old gear.
Who should buy it: you own an Xbox 360 headset you still like, you run a Windows 10 machine with an Xbox controller, or you want the first-party part with a clearly published compatibility list. Who should skip it: you have a current Xbox controller, a plain 3.5mm headset, and no legacy gear — you're paying for capability you'll never touch.
OLCLSS Headset Adapter: Who It's For
The OLCLSS Headset Adapter is the modern, no-nonsense version of the same idea. It's built for Xbox One, One S, One X, Elite 1, Elite 2, Series S and Series X controllers, and it works with most stereo gaming headsets that use a 3.5mm CTIA-standard plug. OLCLSS states the unit is produced by AOLION and includes an original chip so it behaves like the first-party part — a claim I take at face value from the spec sheet rather than from any personal testing.
The interesting part is the control layout. Where the Microsoft adapter's headline feature is legacy compatibility, OLCLSS leans into convenience: volume up and down, microphone mute, and a game/chat balance control, all on the adapter itself. That means you're not diving into the Xbox guide to nudge the chat mixer every time a party gets loud. Everything sits under your thumbs and you never take your hands off the controller. For anyone who plays in a party regularly, that alone changes how the accessory feels in daily use.
Installation is about as simple as it gets. Plug the adapter into the controller, plug the headset into the adapter, done. No console connection, no receiver, no cables running across the room. It's tiny at 4.1 x 3.1 x 0.83 inches, so it adds almost nothing to the controller's footprint — a real difference from the chunkier Microsoft unit at 5.8 x 5.6 x 1.9 inches and 1.76 ounces.
OLCLSS also publishes a warranty position that's unusually specific for this category: a 60-day money-back guarantee and a 24-month guarantee, with a stated 12-hour response window if you're not satisfied. I can't verify how that plays out in practice, but as a written commitment it's more than most unbranded adapters offer.
Who should buy it: you've got a Series S/X or Elite controller, a 3.5mm headset, and you want volume and chat balance at your fingertips. Who should skip it: you rely on a legacy 2.5mm chat headset or Xbox 360 gear, because nothing in this adapter's spec sheet addresses that path.
Side-by-Side: Which Should You Choose?
• Best for Series S/X and Elite controller owners → OLCLSS Headset Adapter. It names Elite 1, Elite 2, Series S and Series X explicitly; Microsoft names Xbox Series X and Xbox One.
• Best for on-controller controls → OLCLSS Headset Adapter. Volume, mic mute and game/chat balance are all built in.
• Best for Windows 10 use → Microsoft Xbox One. It's the only one of the two that lists Windows 10 as a compatible device.
• Best for a slim, low-profile fit → OLCLSS Headset Adapter. 4.1 x 3.1 x 0.83 inches versus 5.8 x 5.6 x 1.9 inches.
• Best for a published compatibility warning list → Microsoft Xbox One. It tells you exactly which headsets won't work, which saves you a return.
• Best for warranty terms stated up front → OLCLSS Headset Adapter. 60-day money-back plus a 24-month guarantee.
• Best if you already own a new Xbox One stereo headset → neither, probably. Microsoft notes the adapter is already included with new stereo headsets designed for Xbox One.
In my opinion, most people shopping this comparison in 2026 should buy the OLCLSS Headset Adapter. If you're on a Series X, Series S, or an Elite controller with a standard 3.5mm headset, it covers exactly what you need, adds volume and chat balance controls the Microsoft unit doesn't advertise, and stays out of the way on the controller.
I'd only steer you to the Microsoft Xbox One adapter in two cases: you're still using a legacy 2.5mm chat headset or Xbox 360 audio gear, or you want to use the adapter with a Windows 10 PC. Those are the jobs OLCLSS doesn't claim. Check the current price on Amazon for both before you decide — it's the one variable that can flip this call.
Yes. OLCLSS lists Xbox One, One S, One X, Elite 1, Elite 2, Series S and Series X controllers as compatible, along with most stereo headsets using a 3.5mm CTIA-standard plug. Microsoft's adapter lists Xbox Series X, Xbox One and Windows 10.
No — nothing in the OLCLSS spec sheet covers legacy 2.5mm chat or console-side audio. That's the Microsoft adapter's territory: game audio via S/PDIF or RCA, chat via the 2.5mm cable using the included jack adapter cable. A microphone is required for chat on both.
The OLCLSS unit measures 4.1 x 3.1 x 0.83 inches; the Microsoft adapter measures 5.8 x 5.6 x 1.9 inches and weighs 1.76 ounces. If a low-profile fit on the controller matters to you, OLCLSS is the smaller of the two.
Maybe not. Microsoft notes the Xbox One Stereo Headset Adapter is already included with new stereo headsets designed for Xbox One, so check your headset box first. If you're buying separately, compare the current price on Amazon for both before deciding.
