Vention USB Bluetooth 5.0 Adapter Black (CDSB0)
A desktop PC or older laptop without built-in wireless rarely has a way to pair a Bluetooth headset or mouse, and this is exactly what the Vention USB Bluetooth 5.0 Adapter Black (CDSB0) solves. It plugs into any USB 2.0 Type-A port and, thanks to its upgraded RTL8761B chipset, brings Bluetooth 5.0 connectivity to a computer instantly. In addition, it works as both a transmitter and a receiver, so it can send audio to a Bluetooth headset or receive files from a paired phone or tablet. Furthermore, it supports audio and microphone signal transmission together, which means Bluetooth headsets handle calls as well as music playback, and it stays backward compatible with Bluetooth 4.0, 4.1, and 4.2 devices.
Once paired, a device reconnects automatically the next time it’s in range, so there’s no need to repeat the setup. The adapter reaches up to 20 meters with an internal antenna amplifier, and it holds up to 7 devices connected simultaneously, so a keyboard, mouse, and headset can all stay linked at once. Consequently, it suits desktops, laptops, and any computer that needs Bluetooth added through a simple USB dongle rather than an internal hardware swap.
Key Features
In short, this adapter stands out in five areas:
- RTL8761B Bluetooth 5.0 chipset, which, in turn, delivers stable, low-latency wireless connections
- Transmitter and receiver in one, so it sends audio to headsets and receives files from phones or tablets
- Audio and microphone signal support, covering both music playback and voice calls on Bluetooth headsets
- Up to 20 meters of range with an internal antenna amplifier for wide coverage
- 7 simultaneous device connections, keeping a keyboard, mouse, and headset paired at the same time

Who This Adapter Is Best Suited For

- Anyone running several Bluetooth accessories together, since support for 7 simultaneous connections keeps a mouse, keyboard, and headset all paired at once
- Bluetooth headset users who take calls, because the adapter carries microphone signal alongside audio, rather than playback only
