Better Bluetooth Performance

for Sonnet's xMac mini Server, RackMac mini, and DuoModo xMac mini Module and supporting Mac and Windows computers
For any Mac mini® user who mounted their computer in one of Sonnet’s Mac mini rackmount solutions, improving your computer’s Bluetooth® performance is simple — plug in a Sonnet Long-Range USB Bluetooth 4.0 Micro Adapter. Connected to the front panel USB port, this adapter moves your Bluetooth connection to outside the enclosure, enabling better performance with mice, keyboards, headsets, speakers, printers, phone, tablet, and other Bluetooth devices.

macOS and Windows Compatible

Supported under macOS® 10.12+, and Windows® 11 and 10, the Long-Range USB Bluetooth 4.0 Micro Adapter works with a wide variety of computers. Whether you need to add Bluetooth wireless connectivity to a computer without it built in or want to upgrade your computer’s Bluetooth to a later version, the Sonnet adapter is a great solution.

Supports Wireless Music Streaming Stereo Audio

Stream tunes from your computer to Bluetooth headphones and speakers.

Small Size
Sonnet’s Long-Range USB Bluetooth 4.0 Micro Adapter is so small that it almost disappears when you plug it in.

Simultaneously at up to 3Mbps
You can pair and use up to seven devices at the same time with the Long-Range USB Bluetooth 4.0 Micro Adapter. To enable quick file transfers and music streaming, the adapter offers Enhanced Data Rate (EDR) support with transfers speeds of up to 3Mbps.
