If you want a tiny, no-fuss Bluetooth upgrade for a desktop, laptop or Raspberry Pi that has no built-in Bluetooth, choose Kinivo USB; if you need a full wireless gaming headset that hops between PC, PS5, Switch and phone, choose BAIHUAFRU 2.4GHz. Those are two completely different jobs, and the right pick comes down to what you're actually trying to do.
• Kinivo USB biggest strength: A Bluetooth 4.0 Class 2 dongle that adds wireless to Windows 11/10/8.1/8, Raspberry Pi and Linux machines, with up to 30 feet (10 m) of range and a two-year warranty.
• Kinivo USB biggest trade-off: It's a receiver, not a listening device — no speakers, no mic, no battery. It only matters if your computer lacks Bluetooth and you already own headphones or a controller.
• BAIHUAFRU 2.4GHz biggest strength: A 176 g over-ear headset with 4-in-1 connectivity (USB-C, USB-A, Bluetooth 5.0, 3.5 mm), a detachable AI noise-cancelling mic, 50 mm drivers and up to 30 hours of battery.
• BAIHUAFRU 2.4GHz biggest trade-off: It's bigger and heavier than a dongle, needs charging, and the mic behaves best over the 2.4GHz connection rather than Bluetooth.
• Who Kinivo USB is for: Anyone with a Bluetooth-less PC, Pi or Linux box who wants to connect a headset, printer or Xbox controller.
• Who BAIHUAFRU 2.4GHz is for: Gamers and students who want one headset that works across console, PC and commute.
Think of the Kinivo BTD400 as a missing part rather than a gadget. It's a USB Bluetooth adapter built to give wireless capability to a machine that doesn't have it: 32-bit and 64-bit Windows 11, 10, 8.1 and 8, plus Raspberry Pi and Linux PCs. Once it's in, you can pair the Bluetooth devices you already own — phones, printers, headsets and stereo headphones — and it even covers the Xbox One Wireless Controller with Bluetooth. If your desktop has no Bluetooth radio at all, this is the kind of part that quietly fixes an entire category of annoyance.
The numbers are modest but honest. Bluetooth 4.0 Class 2 with low energy technology, and up to 30 feet (10 meters) of range. In a normal room that means you can walk to the kitchen and stay connected to a headset. It won't punch through a whole house, and it isn't meant to. The physical footprint is tiny — roughly 0.5" long, 0.25" wide and 0.75" tall, weighing about 4.54 grams — so it's the kind of thing you plug in and forget. It ships in black as a single unit.
Setup is where you should pay attention. Windows 8.1 and 8 use the default Bluetooth stack and are plug-and-play, while Windows 11 and 10 need a driver installation. Raspberry Pi users get Raspbian and Ubuntu support. So if you're on a modern Windows machine, budget a few minutes for the driver rather than expecting instant magic.
BAIHUAFRU 2.4GHz: Who It's For
The BAIHUAFRU headset solves the opposite problem. Instead of adding wireless to your computer, it gives you the thing you listen and talk through. The pitch is one headset for everything, and the connectivity backs it up: USB-C, USB-A, Bluetooth 5.0 and 3.5 mm wired, described as a 4-in-1 setup. That means PC, Mac, laptop, PS5, PS4, Switch, and Xbox via 3.5 mm. The package includes both a Type-C dongle and a USB-A adapter, so you're not hunting for a converter on day one.
The microphone is the headline feature. It's a detachable AI noise-cancellation mic designed to filter out keyboard clicks and fan noise so your teammates hear your voice rather than your room. Read the fine print, though — the notes state that Bluetooth mode may not support the mic, and that the 2.4GHz connection improves mic stability. If voice chat is the point, use the dongle, not Bluetooth. There's also a Child Mode with balanced audio and an 85 dB volume ceiling, which is a genuinely thoughtful touch for households with kids sharing the headset.
Comfort looks well considered for long sessions. At 176 g with soft protein leather over-ear cushions and an adjustable headband, this is aimed at marathon play rather than a quick call. The audio hardware is a 50 mm dynamic driver with 32 ohm impedance, 115 dB sensitivity and a 20 Hz–20,000 Hz frequency range, so expect the deep-bass, crisp-highs presentation gaming headsets usually go for. It's a white and pink colorway, which will either delight you or not — there's no neutral option listed.
Battery life is the practical win: up to 30 hours per charge and a full recharge in about 2 hours, with low latency stated at ≤30 ms over 2.4GHz. That's the kind of runtime that gets you through several evenings without thinking about a cable. Controls are inline and push-button, covering volume and a mic mute switch.
Who should skip it? If you want a neutral-looking headset, if you mostly take calls over Bluetooth and need the mic, or if you already own great headphones and just need Bluetooth on your PC — in that last case, the Kinivo is the cheaper, simpler answer. Also note it's covered by a one-year warranty rather than two.
• Best for adding Bluetooth to a PC, Pi or Linux box → Kinivo USB. It exists precisely for machines with no built-in Bluetooth.
• Best for actually listening and talking → BAIHUAFRU 2.4GHz. It's the headset; the Kinivo has no speakers or mic.
• Best for cross-platform gaming → BAIHUAFRU 2.4GHz. USB-C, USB-A, Bluetooth 5.0 and 3.5 mm cover PC, PS5, PS4, Switch and Xbox (via 3.5 mm).
• Best for long sessions → BAIHUAFRU 2.4GHz. 176 g, over-ear protein leather cushions and up to 30 hours of battery.
• Best for controllers and accessories → Kinivo USB. It pairs the Xbox One Wireless Controller and other Bluetooth peripherals.
• Best for quiet, stable voice chat → BAIHUAFRU 2.4GHz over 2.4GHz. The notes flag Bluetooth as the weaker path for the mic.
• Best for families with kids → BAIHUAFRU 2.4GHz. Child Mode caps volume at 85 dB.
• Best for a set-and-forget fit → Kinivo USB. About 4.54 g, plug it in and leave it.
In my opinion, these two don't really compete — they answer different questions, so the honest recommendation is to buy based on what's missing from your setup. If your computer has no Bluetooth and you already own headphones, a controller or a printer you want to connect, I'd buy the Kinivo USB. It's the smallest, most targeted fix, and the two-year warranty plus US-based support makes it an easy call for a part you'll never think about again. If you need the audio gear itself — a headset for PS5, Switch, PC and phone with a detachable noise-cancelling mic and 30 hours of battery — I'd buy the BAIHUAFRU 2.4GHz, and I'd use the 2.4GHz dongle rather than Bluetooth for voice chat. For most gamers reading this, the BAIHUAFRU is the more complete purchase.
FAQ
Yes. It lists PC, Mac, laptop, PS5, PS4, Switch and Xbox (via 3.5 mm) as compatible, using USB-C, USB-A, Bluetooth 5.0 or the 3.5 mm jack. The Type-C dongle and USB-A adapter are included.
On Windows 8.1 and 8 it's plug-and-play with the default Bluetooth stack. On Windows 11 and 10 you need to install the driver. Raspbian and Ubuntu on Raspberry Pi are also supported.
Check the current price on Amazon for both before deciding, since they sit in very different categories. If you just need Bluetooth on a desktop, the Kinivo is the smaller, simpler purchase. If you need a full headset, the BAIHUAFRU covers more ground with one item.
