How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a desktop hub that turns your existing analog headset into a 7.1 surround-sound setup while charging your gear, choose Corsair ST100; if you need a self-contained wireless gaming headset with 7.1 surround sound, Bluetooth 5.3 and a retractable mic you can actually carry around, choose RK ROYAL KLUDGE HG101.
• Corsair ST100 — biggest strength: a machined aluminum stand with a built-in 3.5mm analog input that unlocks stereo or 7.1 surround sound on a headset you already own, plus dual USB 3.1 inputs for charging and data.
• Corsair ST100 — biggest trade-off: it isn't a headset at all. No drivers, no mic, no battery, no Bluetooth — it only does surround sound if you pair it with a wired analog headset and a PC.
• RK ROYAL KLUDGE HG101 — biggest strength: everything is in the box. Over-ear drivers, 7.1 surround sound, Bluetooth 5.3, a 2-in-1 wireless receiver, USB-C and a retractable noise-canceling mic.
• RK ROYAL KLUDGE HG101 — biggest trade-off: it's plastic-bodied ABS/PU construction with a 1-year warranty, and it's built for heads, not for desks — there's no hub, no USB passthrough, no RGB ecosystem to sync.
• Who each pick is for: pick the Corsair ST100 if you're a PC player with a good analog headset and a messy desk; pick the RK ROYAL KLUDGE HG101 if you want one headset that handles PC, PS4, PS5 and Switch.
Think of the ST100 as a piece of furniture that happens to do audio. The chassis is aluminum with a painted finish, and it measures roughly 4.72 by 9.84 by 4.72 inches — a rectangular or cylindrical riser shape that holds a headset up off your desk instead of letting it slump onto your mousepad. In my opinion, that's the whole point: it changes how your setup looks and feels before it changes how anything sounds.
The audio part is where it earns its keep. There's a built-in 3.5mm analog input that enables full-range stereo or 7.1 surround sound for multi-channel audio. Notice what that means: the surround processing happens through the stand, so your existing wired analog headset becomes the surround headset. If you already love the fit of your current cans, you don't have to replace them — you just need the ST100 and a PC to run it. Two USB 3.1 inputs sit within easy reach for charging a headset, phone or controller and moving data faster than a front-panel port usually manages.
Then there's CUE software, which controls RGB lighting and audio settings and syncs with other Corsair RGB devices. Nine lighting zones means the stand can be matched to the rest of a Corsair-lit battlestation. It ships with the stand, a 1.8m USB 3.1 Micro B cable, a quick start guide and a warranty card, and Corsair backs it with a 2-year warranty.
RK ROYAL KLUDGE HG101: Who It's For
The HG101 is the opposite approach: instead of upgrading the gear around your head, it replaces the thing on your head. It's an over-ear headset built from ABS, copper, metal, polyester, PU and TPE, with memory foam ear pads that pivot slightly to match your contours for a secure seal. The cups fold, which matters more than people expect — folded, it's a headset you can toss in a bag rather than a permanent desk ornament.
Audio specs are straightforward: dynamic drivers, 32 ohm impedance, 20 KHz frequency response and 109 dB sensitivity. Low impedance means it's easy to drive from a controller, a phone or a laptop jack — you're not hunting for an amp. It supports 7.1 surround sound and stereo, so the surround processing is part of the headset's own feature set rather than something you bolt on externally.
Connectivity is the real story. Triple modes: Bluetooth 5.3 with a 10m range, wired over USB-C, and wireless through the included 2-in-1 receiver. There are dual USB-A and Type-C ports, so you don't need separate receivers or adapters to move between devices — the box includes the headset, the 2-in-1 wireless receiver, a USB-C cable and a manual. It's listed as working with PC, PS4, PS5 and Switch.
The mic is retractable and omni-directional with 360° capture and environmental noise filtering — pull it out when you're in a party chat, push it back in when you're not. Controls use push buttons plus touch control, and the noise control is environmental noise cancellation rather than active noise cancellation, so read that as "your teammates hear less of your keyboard," not "you hear less of the world." Battery charge time is 3.5 hours, and the warranty is 1 year.
Buy it if you want one headset that follows you across PC, PlayStation and Switch, if you take your gear places, or if you've never owned a wired analog headset and don't want to start now. Skip it if you want a desk centerpiece, USB passthrough charging, or a multi-year warranty.
Side-by-Side: Which Should You Choose?
• Best for surround sound out of the box → RK ROYAL KLUDGE HG101. Headset, drivers, mic and surround all in one package.
• Best for desk organization and charging → Corsair ST100. Dual USB 3.1 inputs plus an aluminum riser that holds your headset properly.
• Best for multi-device and console use → RK ROYAL KLUDGE HG101. Bluetooth 5.3, USB-C wired, 2-in-1 receiver, listed for PC, PS4, PS5 and Switch.
• Best for a built-in mic → RK ROYAL KLUDGE HG101. Retractable omni-directional with 360° capture and noise filtering. The ST100 has no mic at all.
• Best for portability → RK ROYAL KLUDGE HG101. Foldable cups; the ST100 is a 1.5 lb desk object.
• Best for software control and RGB sync → Corsair ST100. CUE software manages lighting and audio across nine zones and syncs with other Corsair RGB gear.
• Best for long-term peace of mind → Corsair ST100. A 2-year warranty versus 1 year on the HG101.
• Best for easy-to-drive audio → RK ROYAL KLUDGE HG101. 32 ohm impedance and 109 dB sensitivity mean it plays loud off modest sources.
• Best for a tidy, single-purpose PC setup → Corsair ST100. If your surround chain already lives on your desk, this finishes it.
If I'm buying for myself, I'd take the Corsair ST100 — but only because I already own a wired analog headset I like, and I'd rather upgrade the desk and the surround processing than replace a headset that fits me well. The aluminum build, the dual USB 3.1 inputs and the 2-year warranty make it the more durable long-term purchase in my opinion. That said, if you don't have a wired analog headset, or you game on PS5 and Switch as much as PC, the ST100 is the wrong answer entirely — get the RK ROYAL KLUDGE HG101 instead and have surround sound, a mic and wireless freedom on day one, no PC required. Check the current price on Amazon before you commit; both sit in very different budget brackets.
FAQ
Play something with directional audio — a game where you can hear footsteps or vehicles behind and beside you — and listen for whether sounds move around you rather than staying flat in front. On the Corsair ST100, confirm your headset is connected to the 3.5mm input and check the audio settings in CUE software. On the RK ROYAL KLUDGE HG101, verify 7.1 is active for the connection you're using, whether that's Bluetooth, the 2-in-1 receiver or USB-C.
Check the chain in order. Make sure the headset is fully seated — 3.5mm into the Corsair ST100's analog input, or the HG101 on the correct input for its mode. Confirm the surround option is actually enabled in your software or console settings rather than just stereo. If one channel drops out on the ST100, try the included 1.8m USB 3.1 Micro B cable in a different port before assuming the unit is faulty.
You can't convert a stereo headset into a true multi-channel one with settings alone, but you can add surround processing. The Corsair ST100 does this externally for any wired analog headset through its 3.5mm input. The RK ROYAL KLUDGE HG101 does it internally as part of a headset that already includes the drivers and the mic. If you own neither headset nor stand, the HG101 is the shorter path — there's nothing else to buy.
