Review: Tiny, Reliable, and Plug-and-Play Bluetooth for Any PC - Tiny, Reliable, and Plug-and-Play Bluetooth for Any PC The TP-Link UB400 Bluetooth 4.0 adapter is a remarkably simple way to add Bluetooth to an older desktop or laptop that lacks it. It’s about the size of a fingernail—once plugged in, you can leave it there permanently without blocking adjacent USB ports. Setup is as easy as it gets: on Windows 10 or 11, it’s fully plug-and-play; for Windows 7 or XP, TP-Link provides free drivers. In my experience, installation took seconds and devices paired immediately. Performance is solid for its class. It maintains stable connections for headphones, mice, keyboards, and even game controllers within a reasonable 50- to 60-foot range. Audio quality over A2DP is clean, and latency with Bluetooth 4.0 peripherals is minimal for everyday use. It’s not built for high-end audio streaming or gaming headsets, but for standard wireless accessories it works seamlessly. I especially appreciate that it’s low-profile, energy-efficient, and doesn’t run hot even after hours of use. The connection is consistent, and it automatically reconnects to previously paired devices after reboot—no fiddling required. Bottom line: A dependable, compact, and truly plug-and-play Bluetooth dongle that delivers excellent value for basic wireless connectivity. Ideal for upgrading desktops or travel laptops, and proof that simple, inexpensive tech can still work perfectly.

### ⭐⭐⭐⭐⭐ Cheap bluetooth adapter
*by A***S on November 2, 2025*

I bought this back in March of 2020 when I built my first computer and forgot to include a Bluetooth module. This device worked great and allowed me to use my wireless headphones with my computer. I have since then gotten a Bluetooth module but I still keep this adapter for whenever I need it and it hasn't failed me yet. It has a pretty small form factor which is nice because it doesn't stick out much and isn't an annoyance when using it. The range is okay (at least for the 2020 version), but once there are a couple walls between me and the adapter the Bluetooth starts to get pretty choppy. Overall, it is a sleek and durable adapter that I would recommend for anyone that needs Bluetooth
