How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a complete wired gaming headset that delivers virtual surround sound, a boom mic and long-session comfort straight out of the box, choose MARVO USB Gaming Headset; if you need a compact external sound card that upgrades the headphones you already own with virtual 7.1, four listening modes and a dedicated mic input across Windows, Mac, iOS and Android, choose S.M.S.L SMSL Nano ONE.
• MARVO's biggest strength: an all-in-one headset — 50 mm dynamic drivers, virtual surround sound, passive noise cancellation from closed-back cups, a clear voice mic and a braided USB cable — with nothing else to buy.
• MARVO's biggest trade-off: it only works over USB, so it is tied to PS4/PS5, Switch, PC, laptop and Mac; there is no 3.5 mm jack for phones, tablets or older controllers.
• S.M.S.L's biggest strength: a plug-and-play DSP sound card with virtual 7.1 surround, Music/Game/7.1 Cinema/Voice modes, a 20 mW @ 600Ω output for hard-to-drive headphones, and separate headphone and mic jacks.
• S.M.S.L's biggest trade-off: it is a processor, not a headset — you supply the headphones and microphone, so the final sound depends on what you already own.
• Pick MARVO if you want one box, one cable and a headset ready for console and PC gaming tonight.
• Pick S.M.S.L if you already like your headphones and want to add surround processing, cleaner audio and better voice pickup to them.
The MARVO H8618 is built around one idea: get a gamer from unboxing to playing with as few decisions as possible. The 50 mm dynamic drivers cover a 20 Hz–20 kHz range with 30 ohm impedance and 114 dB sensitivity, which tells me these are easy-to-drive cans that a plain USB port can push without help. Virtual surround sound is the headline feature, and it is the one that matters most in competitive shooters — the processing spreads game audio around you so footsteps and gunfire have a direction instead of collapsing into a flat stereo smear.
Comfort is clearly a design priority. Protein-skin ear pads over memory foam, an adjustable headband and closed-back cups give you a snug fit plus passive noise cancellation — not active electronics, just physical isolation from the room around you. That combination is what I look for in a headset you wear for a four-hour ranked session. The push-button controls keep things simple, the braided cable is built for daily abuse, and the RGB lighting is there if you want your desk to look the part. The mic captures voice clearly enough for callouts, and the whole thing runs plug-and-play over USB on PS4, PS5, Switch, PC, laptop and Mac.
Who should buy it: console and PC gamers who want a single purchase that covers sound, voice chat and comfort, and gift-buyers shopping for a teenage or adult gamer who does not want to fiddle with settings. Who should skip it: anyone gaming on a phone or tablet, or anyone with a favourite pair of wired headphones they would rather keep. There is no 3.5 mm jack here, so this is a USB-only relationship. It also ships with a two-year manufacturer warranty, which is a reasonable signal of confidence for a headset at this level.
The SMSL Nano ONE Pro is a different category of product entirely, and I want to be blunt about that: it makes no sound on its own. It is an external sound card — a small box that sits between your device and your headphones and does the audio processing your motherboard or phone cannot. Inside is a 16-bit/48 kHz DSP chip with a claimed maximum signal-to-noise ratio and negligible distortion, and on the outside you get an independent headphone jack, an independent mic jack and a 2-in-1 audio/mic jack, so you can leave everything plugged in permanently.
The four modes are the real selling point. Game Mode is tuned to make footsteps and gunshots three-dimensionally distinguishable — that is virtual 7.1 surround via software algorithm, needing no extra channels or speakers. Movie mode gives you cinema-style ambience. Music mode aims at clean, lossless-style playback. Voice Enhancement cleans up your mic, and the intelligent noise-reduction algorithm filters keyboard clatter during gaming and background noise during streams. The output stage is rated at 20 mW into 600 ohms, which means it can drive high-impedance headphones that a phone or laptop headphone jack would leave sounding thin.
Connectivity is genuinely broad: one USB-C cable, no drivers, working across Windows, Mac, iOS and Android, plus PlayStation listed among compatible platforms. The magnetic base is a small but smart touch — it snaps onto a metal desk or case and pops off in seconds for travel. Who should buy it: streamers, mobile karaoke and music-production users, and anyone who already owns good headphones and wants surround processing and a proper mic input without buying a whole new headset. Who should skip it: anyone who wants an all-in-one headset, since you still need to supply the cans and the mic.

If I had to pick one, I would buy the MARVO USB Gaming Headset for straight gaming, and I would only switch to the SMSL Nano ONE if I already owned headphones I loved. My reasoning is simple: MARVO removes every extra decision — surround sound, a working mic, comfortable pads and a durable cable all arrive together, and it works on the consoles most people actually play on. The Nano ONE is the smarter buy for a streamer or tinkerer who wants modes, a strong headphone amp stage and a proper mic input, but it is half a solution until you add your own cans. For most shoppers, one box beats two.
how to test surround sound headphones
Play a source with clearly separated directional cues — a shooter, a racing game or a surround demo track — and listen for whether sounds move around you rather than staying left and right. On the MARVO H8618, virtual surround is processed in the headset over USB, so it works as soon as you plug in. On the SMSL Nano ONE, you switch to Game or 7.1 Virtual Cinema mode and let the DSP handle the positioning.
how to get surround sound headphones
You either buy a headset with virtual surround built in, or add a processor that creates it. The MARVO H8618 falls in the first camp: the surround processing is part of the headset and needs no extra hardware. The SMSL Nano ONE falls in the second: it rebuilds sound sources in 3D via a software algorithm and feeds them to whatever headphones you connect, with no extra channels required.
how to make surround sound headphones
If you already own a plain stereo headphone, the practical route is an external processor like the SMSL Nano ONE, which applies virtual 7.1 to your existing cans and gives you Game, Music, 7.1 Cinema and Voice modes. If you are starting fresh, a headset like the MARVO H8618 includes that processing already, so there is nothing to configure beyond plugging in the USB cable.
how to fix surround sound headphones
Start with the source, then the connection. Confirm the surround or spatial setting is actually enabled in your game, console or app, and that the correct output device is selected. On the MARVO, check the USB connection and the push-button controls; on the SMSL, confirm you are in the right mode and that your headphones are seated in the dedicated headphone jack rather than the 2-in-1 port.
