These two look like they compete on a store shelf, but they don't really. One is a small adapter that fixes an audio problem you already have. The other is a pair of earbuds that replaces your audio setup entirely. Your answer depends almost entirely on what you're plugging into — and whether you want a wire or not.
• Ugreen USB — biggest strength: Plug-and-play USB-to-3.5mm audio with a built-in DAC, 16bit/48kHz output, and a 90 dB signal-to-noise ratio for cleaner sound on laptops and desktops.
• Ugreen USB — biggest trade-off: It's wired and it's a converter, not a listening device. You still need your own headphones or mic, and it won't work with PS3.
• Arruilys True — biggest strength: Up to 50 hours of total playtime with the charging case, IPX7 waterproofing, and Bluetooth 5.3 wireless freedom with a dual LED battery display.
• Arruilys True — biggest trade-off: It's wireless-only, so it can't give you a physical jack, and Bluetooth audio is a different experience than a wired DAC connection.
• Choose Ugreen USB if you want to restore or improve the headphone and mic jacks on a computer, console, or single-board device.
• Choose Arruilys True if you want earbuds to carry with you for workouts, commuting, and calls without a cable.
The Ugreen USB adapter is essentially a small external sound card. You plug it into a USB port, and it gives you a TRS 3.5mm jack for headphones and a mic. Inside is a DAC chip that handles high-resolution audio output and noise reduction up to 16bit/48kHz, so the point isn't to add features — it's to give a clean, reliable audio path to a device that either lacks a jack or has a noisy one.
The specs tell you a lot about who this is for. It's driver-free and needs no external power, so it's a true plug-and-play device. Compatibility is unusually broad: Windows 11/10/98SE/ME/2000/XP/Server 2003/Vista/7/8, Linux, Mac OSX, PS5, PS4, Google Chromebook, Windows Surface Pro 3, and Raspberry Pi. It handles stereo and a 5.1 channel configuration, with a 90 dB signal-to-noise ratio — a solid figure for a compact adapter. It's built from durable ABS and weighs just 18.14 g, so it disappears in a bag. Ugreen backs it with a 24-month warranty.
So who should buy it? Anyone whose computer's headphone jack is broken, hissy, or missing. Gamers on PS5 or PS4 who want to run a wired headset. People building a Raspberry Pi project who need audio out. Students and office workers on laptops with a single USB-C or USB-A port who'd rather not fight with onboard audio. Musicians doing light recording who need a simple mic input.
Arruilys True: Who It's For
The Arruilys True is a pair of true wireless earbuds built around convenience and stamina. The headline number is battery: up to 50 hours of total listening time with the charging case, and a dual LED display that shows the battery status of both the earbuds and the case. That display is a genuinely practical touch — no guessing whether the case is charged before a trip.
The audio hardware is a 13mm dynamic driver, tuned for rich bass, clear vocals, and crisp highs. There are built-in microphones for calls. Connectivity is Bluetooth 5.3, which brings faster pairing, lower latency, and a more stable connection, plus automatic reconnection the moment you open the case. Touch controls on both earbuds handle music, volume, calls, and the voice assistant without reaching for your phone.
The physical design is aimed squarely at movement. An IPX7 waterproof rating means sweat, rain, and splashes aren't a concern. The in-ear fit is ergonomic and lightweight, and Arruilys includes S/M/L ear tips so you can dial in a more secure fit. The color is silver white. It ships with a cable and carries a 1-year manufacturer warranty.
Who should buy it? Runners, gym-goers, and commuters who want earbuds that survive sweat and rain. Travelers who hate charging constantly. Anyone who takes a lot of calls on the go and wants the mic built in. People who want the freedom of no cable between phone and ears.
Who should skip it? Anyone who needs a wired connection — to a PS5 controller, a desktop with no Bluetooth, or a Raspberry Pi. If your priority is a physical headphone jack or a dedicated mic input, these earbuds simply don't address that problem. And if you prefer over-ear or wired headphones for critical listening, the in-ear wireless form factor won't suit you.
Side-by-Side: Which Should You Choose?
• Best for battery life → Arruilys True. Up to 50 hours with the case, plus a dual LED display so you can actually see the charge level.
• Best for gaming on PS5/PS4 → Ugreen USB. It's listed as compatible with both consoles and gives you a wired headset path. (Not PS3.)
• Best for workouts and rain → Arruilys True. IPX7 waterproofing and a secure in-ear fit with three ear tip sizes.
• Best for travel and commuting → Arruilys True. Wireless, auto-reconnecting, and pocketable with 50 hours of total playtime.
• Best for Raspberry Pi / Linux / older Windows → Ugreen USB. The compatibility list is remarkably long, covering Linux, Mac OSX, and Windows versions going back to 98SE.
• Best for hands-free calls → Arruilys True. Built-in mics and touch controls let you manage calls without touching your phone.
• Best for a permanent desk setup → Ugreen USB. Plug it in once and forget it — no drivers, no charging, no pairing.
In my opinion, these aren't really substitutes, so I'd pick based on the problem in front of me. If your computer, console, or Pi needs a clean headphone and mic jack, I'd buy the Ugreen USB — the DAC, the 90 dB SNR, the driver-free setup, and that enormous compatibility list make it the more useful tool for a fixed setup.
If you want earbuds to take everywhere — gym, commute, calls — I'd buy the Arruilys True for the 50-hour playtime, IPX7 rating, and Bluetooth 5.3 convenience. For most people shopping casually for "earbuds," the Arruilys True is the more natural buy.
If you're weighing cost, check the current price on Amazon before deciding, since both are budget-friendly categories where value shifts.
They're not directly comparable. Ugreen uses a wired DAC with 16bit/48kHz output and a 90 dB signal-to-noise ratio for a clean wired signal. Arruilys relies on Bluetooth 5.3 and 13mm dynamic drivers. Wired generally means fewer compression variables; wireless means freedom. Pick based on whether you want a wire.
The Arruilys True is a Bluetooth device, so it pairs with Bluetooth-capable phones, laptops, iPhones, and Android devices. The Ugreen USB is the one explicitly listed as compatible with PS5 and PS4 (not PS3). If console gaming is your goal, Ugreen is the safer bet.
Arruilys True, clearly. It has an IPX7 waterproof rating for sweat and rain, a secure in-ear fit, and S/M/L ear tips. The Ugreen adapter isn't meant to be worn or moved around — it's a desk or console accessory.
No. It's plug-and-play with no drivers or external power required, and it works across Windows, Linux, Mac OSX, Chromebook, and Raspberry Pi. That's one of its biggest practical advantages over a typical internal sound card.
