How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to turn a PS5, Switch or PC into a wireless audio setup and keep using the headphones you already own, choose YOCOWOCO USB-C; if you need wired earbuds built for side sleeping, white noise and all-night comfort on a USB-C phone or tablet, choose GREKING Sleep Headphones USB-C.
• YOCOWOCO USB-C — biggest strength: a rare 2-in-1 dual-port transmitter with both USB-A and USB-C plugs, so one small adapter covers a PS5, a Switch, a laptop and a desktop. It supports aptX-HD, aptX-AD, aptX-LL, aptX and SBC, with color-coded LEDs that show which codec is active.
• YOCOWOCO USB-C — biggest trade-off: it is not a pair of headphones and it is not a receiver. It only transmits audio, needs headphones that support the low-latency codec to actually get low latency, and it works with audio-only devices — no data transfer.
• GREKING Sleep Headphones USB-C — biggest strength: genuinely low-profile silicone earpieces with retention loops, designed so side sleepers stop fighting their own ears, plus an in-line mic and three-button remote.
• GREKING Sleep Headphones USB-C — biggest trade-off: it is a wired USB-C product with no battery, so it is tethered to your device, and its 6 mm dynamic drivers are tuned for smooth, quiet listening rather than big sound.
• Who each pick is for: YOCOWOCO USB-C for console and PC gamers who want to cut the cable on their existing headphones; GREKING Sleep Headphones USB-C for side sleepers and quiet late-night listeners on USB-C phones, tablets and laptops.
YOCOWOCO USB-C is a Bluetooth audio transmitter, not a listening device. You plug it into a source that has no Bluetooth of its own — a PS5, a Switch, a PC, an iMac — and it beams the game or call audio out to Bluetooth headphones or earbuds you already own. The hook is the dual-port body: one end is USB-A, the other USB-C, so the same 2.36 x 0.91 x 0.51 inch white adapter lives happily on a console dock and a laptop without you buying a second dongle. It weighs 12.75 g, which is basically nothing hanging off a port.
Setup is plug-and-play: connect the adapter, put your headphones in pairing mode, and they connect. After that first pairing they auto-reconnect, which is the difference between "I'll use it" and "I can't be bothered". There's also an included 3.5mm mic, which helps balance game audio and party chat. Two notes before you buy. First, it is audio-only — no data transfer, so don't expect it to move files. Second, it is for people who want to keep their current headphones. If you're happy buying a dedicated wireless gaming headset, this adapter isn't solving your problem. And if your headphones are wired-only, skip it entirely. It ships with a 24-month warranty, which is a reasonable cushion for a small accessory that lives in a port.
GREKING Sleep Headphones USB-C: Who It's For
GREKING Sleep Headphones USB-C, model S800 USB C, goes after a very specific problem: falling asleep on your side without a hard plastic earbud stabbing you in the ear. The earpieces are made from soft silicone and shaped to sit low-profile, with integrated ear retention loops so they stay put when you roll over. That combination — soft material plus a loop that anchors the bud — is exactly what side sleepers need, and it's the reason this product exists at all. Both the model name and the description call out small ears and side sleepers directly.
Sound is deliberately tuned smooth and non-fatiguing rather than punchy. With 6 mm dynamic drivers, 32 ohm impedance, 102 dB sensitivity and a 20 kHz frequency response ceiling, this is a modest, easy-listening configuration built for white noise apps, podcasts, audiobooks and quiet music at bedtime. Nobody should buy this expecting thumping bass. But for two hours of rain sounds while you drift off, a gentle tuning is the correct design choice, not a compromise.
The cable is described as sufficiently long, which matters more than people think when your phone is on the nightstand and you're turning over. There's a metal housing, an in-line microphone and a three-button remote for volume, playback, calls and voice assistant — so you can pause the podcast without hunting for your phone in the dark. Connectivity is wired USB Type C, which covers mainstream USB-C audio devices including iPhone 15/16/17 and Samsung S24/S25-series phones, plus tablets, laptops and desktops. No battery means no charging and no mid-night dead earbud, but it also means you're physically tethered. It's a one-year manufacturer's warranty on a 40 g product. If you need wireless freedom or serious isolation, this isn't it — noise control here is sound isolation from the fit, not active cancellation.
• Best for cutting the cord on a PS5 or Switch → YOCOWOCO USB-C. It's the only one of the two that transmits Bluetooth audio at all.
• Best for low-latency gaming audio → YOCOWOCO USB-C, provided your headphones support aptX-LL. Without that support, expect ordinary Bluetooth latency.
• Best for side sleepers and small ears → GREKING Sleep Headphones USB-C. Low-profile silicone earpieces and retention loops are built for exactly that.
• Best for white noise, audiobooks and podcasts in bed → GREKING Sleep Headphones USB-C. The smooth, non-fatiguing tuning suits long, quiet listening.
• Best for never charging anything → GREKING Sleep Headphones USB-C. It's wired, so there's no battery to manage — but you are attached to your device.
• Best for multi-device flexibility → YOCOWOCO USB-C. USB-A and USB-C in one body covers consoles, desktops, laptops and tablets.
• Best for calls and quick controls on the go → GREKING Sleep Headphones USB-C. In-line mic, three-button remote and voice assistant access, all on the cable.
• Best for keeping the headphones you already love → YOCOWOCO USB-C. That's its entire purpose.
In my opinion, these two products barely compete — they solve opposite problems, so the honest answer is to buy the one that matches your setup. If I had to pick one as the more broadly useful purchase, I'd take YOCOWOCO USB-C. It upgrades hardware you already own, works across consoles and computers thanks to the dual-port design, and the codec indicator LEDs plus aptX-LL support make it a genuinely thoughtful little adapter. I'd only steer you to GREKING Sleep Headphones USB-C if sleep is the actual goal — and if it is, its silicone low-profile design and wired, battery-free simplicity make it the better fit. Check the current price on Amazon for whichever one matches your need before deciding.
Yes — it's designed for PS5, Switch, PC, iMac and similar audio-only devices, with both USB-A and USB-C connectors so it fits either port style. Just note it transmits audio only, with no data transfer.
Yes. They're wired USB Type C and the spec lists iPhone 15/16/17 and Samsung S25/S24/S23 series among compatible devices, along with mainstream USB-C tablets, laptops and desktops.
Not any. The roughly 40 ms aptX-LL figure requires headphones that support aptX-LL. Other codecs like aptX-HD, aptX-AD, aptX and SBC are supported, but latency will be typical Bluetooth latency.
Probably not the best match. The tuning is smooth and non-fatiguing with 6 mm drivers, and noise control is passive sound isolation from the fit — not active cancellation. They're aimed at quiet, comfortable all-night listening.
