• MillSO USB — biggest strength: a USB sound card with two TRRS 3.5mm jacks, so two headsets or speakers run off one USB port with a built-in DAC, no drivers, plug and play.
• MillSO USB — biggest trade-off: it is not headphones. It's an adapter, it needs TRRS plugs (three black rings), and it won't work with TS/TRS mics, dual-plug headsets, Apple-standard headphones, PS3, Xbox, TVs, amps or cars.
• REHOC 3.5mm — biggest strength: a complete wired gaming headset — 50mm drivers, 4D stereo surround, a noise-reducing mic, a 2m cable and an adaptive retractable head beam.
• REHOC 3.5mm — biggest trade-off: it's a 3.5mm wired headset with no USB audio chip of its own, so if your PC's jack is noisy, dead or already occupied, you'll need something else to route the sound.
• Who each pick is for: MillSO USB for anyone fixing or sharing PC audio; REHOC 3.5mm for anyone who just wants a headset to plug in and play.
The MillSO USB is a tiny sapphire-blue metal adapter that turns one USB 2.0 port into two 3.5mm TRRS jacks. Inside is a smart DAC chip doing high-speed decoding, plus high-density shielding over 20 strands of enameled copper to keep the signal stable. In my opinion the real draw is the splitter idea: two people, one computer. Two headsets for a movie night, two sets of speakers for a shared desk, or a friend learning alongside you on the same machine.
It's also the fix-it tool. If your laptop's 3.5mm port is crackly, loose or simply missing, this bypasses it entirely and gives you a cleaner stereo path. It's driver-free and USB bus-powered, so no external power and no software to install. Windows 10, 8.1, 8, 7, Vista and XP are all listed as compatible, along with Linux, Raspberry Pi, iOS 8.6 and up, PS4 and PS5. The stated ceiling is 48 KHz sample rate with a 120 dB signal-to-noise ratio and stereo surround output.
Buy it if you're sharing audio, replacing a broken jack, or wiring a desktop that never had a good sound output. Skip it if you want actual headphones, or if your gear uses TRS or TS plugs — a TRRS plug has three black rings, a TRS plug has two, and this adapter only plays nice with the former. It also won't drive dual-plug headsets, Apple-standard headphones, or anything on PS3, Xbox One, a TV, an amplifier, a CD player, a Switch dock, a car or a truck. And note the mic quirk: both plugs must be TRRS for mic use, and the left/right channels can reverse on some devices. One more thing — you'll likely need to right-click the taskbar sound icon and pick your playback or recording device the first time.
The REHOC 3.5mm is the opposite kind of purchase: a finished pink wired headset built for gaming and voice chat. The headline numbers are a 50mm dynamic driver, a 60 Hz to 20,000 Hz frequency range, 32 ohm impedance, 50 dB sensitivity and a 3% distortion figure. Practically, that 50mm driver and the 4D stereo surround claim are about positional audio — hearing which direction a footstep or a shot came from before you see it.
The mic is the other half of the pitch, and it's a sensible one: a noise-reducing design meant to cut down background hum so your voice comes through in calls and lobbies. There's also a colorful circular breathing light, which is pure gaming-desk aesthetics, and a light cantilever head beam with an adaptive retractable fit so it sits on different head sizes without clamping. The 2m cable gives you room to lean back, and volume control sits on the headset itself. It's ABS plastic, weighs about 0.5 kg, and the plug is a standard 3.5mm jack.
Buy it if you want one cable, one headset and you're done — especially if your PC or notebook already has a working 3.5mm port. Skip it if you need USB audio, if you want a second listener sharing your machine, or if you're after a neutral, understated look; pink with a breathing light is a statement.
• Best for sharing one PC with two people → MillSO USB. Two TRRS jacks on one USB port is the whole point.
• Best for gaming audio and voice chat out of the box → REHOC 3.5mm. 50mm drivers, 4D surround and a noise-reducing boom mic in one unit.
• Best for a broken or missing PC audio jack → MillSO USB. It bypasses the onboard port entirely.
• Best for plug-and-play simplicity → REHOC 3.5mm. No device settings to fuss over if your 3.5mm port already works.
• Best for driver-free setup on older Windows → MillSO USB. Windows 7, Vista and XP are listed, and there's nothing to install.
• Best for positional awareness in shooters → REHOC 3.5mm. The 50mm driver and surround tuning are aimed squarely at that.
• Best for a tidy desk with no cable clutter → MillSO USB. It's a 30 cm adapter weighing 20 g; you supply the headphones.
• Best for a single all-in purchase → REHOC 3.5mm. Adapter plus headset plus mic, in one box.
If I had to pick one, I'd buy the REHOC 3.5mm for a typical Windows PC setup, because most people asking about headphones for a Windows PC want headphones — with a mic, a cable and sound that works the moment you plug it in. But I'd genuinely recommend the MillSO USB instead if your goal is fixing bad onboard audio or letting two people listen at once, since no headset solves that problem. Check the current price on Amazon for whichever one matches your setup before you commit.

Plug the 3.5mm jack into your PC's headphone port — that's all the REHOC 3.5mm needs. If your port is broken, missing or you want two headsets at once, use the MillSO USB adapter instead: it plugs into a USB 2.0 port and gives you two TRRS 3.5mm jacks.

On Windows 10, plug in and then right-click the sound icon in the taskbar, choose Playback or Recording devices, and select the right output. With the MillSO USB you'll see it listed as a C-Media USB headset; with the REHOC 3.5mm you just use the existing audio jack.

Match the plug to the port. A standard 3.5mm plug like the REHOC's goes straight into the PC jack. If your headphones use a TRRS plug with three black rings and you want mic support, the MillSO USB handles that — just make sure both plugs are TRRS, since it won't work with TRS or TS mics.

Once connected, set the device as your default output and adjust volume both on the computer and inside the app you're using. The MillSO USB is driver-free and bus-powered, so there's nothing to install; the REHOC 3.5mm has its own inline volume control and a 2m cable for everyday desk use.
