Bluetooth USB Dongle Adapter

This compact Bluetooth USB dongle adds wireless connectivity to a desktop PC or laptop that has no Bluetooth built in. Plug it into a spare USB port and you can pair wireless headphones, speakers, mice, keyboards and other Bluetooth accessories without opening the computer or fitting an internal card. Built on the CSR Bluetooth 5.0 platform, it brings a modern Bluetooth feature set to older machines in an adapter so small it barely protrudes from the port, and can stay plugged in on a laptop that travels.

Why Choose This Bluetooth USB Dongle Adapter?

Many desktops and older laptops were sold without Bluetooth, which leaves wireless headphones, speakers and peripherals unusable. A USB dongle is the simplest fix: no internal upgrade, no screwdriver, and no permanent change to the machine. Bluetooth 5.0 gives a faster, more stable connection with lower power draw than older Bluetooth versions, so paired audio devices hold their link and wireless mice and keyboards respond without lag. Because the adapter is tiny, it works as a fit-and-forget upgrade for a home theatre PC, an office workstation or a laptop that moves between rooms.

Key Features

• Bluetooth 5.0 wireless: a modern Bluetooth version with faster pairing and a more stable link than older adapters.
• CSR platform: built on the widely used CSR Bluetooth chipset family for broad device compatibility.
• Plug-and-play on most Windows 10 and 11 PCs: the adapter is recognised without installing drivers on most current Windows systems.
• Pairs with headphones, speakers, mice and keyboards: one adapter covers wireless audio and wireless peripherals alike.
• Compact nano design: sits almost flush with the USB port, so it can stay plugged in during travel.
• No internal upgrade needed: adds Bluetooth to a desktop or laptop through a spare USB port.

Best Suited For

The dongle suits anyone with a desktop PC or older laptop that lacks Bluetooth: home workers adding a wireless headset or mouse, home theatre PC owners connecting a Bluetooth speaker or soundbar, and anyone who wants wireless headphones on a machine that only has wired audio today. It is also a handy spare for a system whose built-in Bluetooth has stopped working.

Setup and Connection Guide

Insert the dongle into a spare USB port and let the operating system detect it; on most Windows 10 and 11 systems no driver installation is needed. Open the Bluetooth settings, switch Bluetooth on, and put your headphone, speaker, mouse or keyboard into pairing mode. Select the device from the list and confirm the pairing. If the computer already has built-in Bluetooth, use the dongle as the active adapter in the Bluetooth settings. Keep the dongle plugged in while the paired devices are in use, and remove it only when the computer is not relying on it.

Frequently Asked Questions

Will this work with my PC?
It needs a spare USB port and a Windows PC; on most Windows 10 and 11 systems it works without installing drivers. Check the operating system and USB port before buying if you use an older version of Windows or a different system.

Can I pair headphones and a mouse at the same time?
Yes. The dongle can maintain connections to several Bluetooth devices at once, so a wireless headset and a wireless mouse or keyboard can be used together.

What range can I expect?
Bluetooth is designed for use within a room, so the dongle works best with devices near the computer. Walls and other wireless equipment can shorten the usable range, so keep paired devices in the same room for the most reliable connection.
