- Samsung has filed a patent for earphones that transmit audio via UWB instead of Bluetooth.
- The company says UWB enables higher-quality audio, lower latency, and reduced interference.
- This patent isn’t a guarantee that we’ll see UWB earphones in the future.
The vast majority of wireless earphones use Bluetooth for audio transmission, but we’ve also seen some products with 2.4GHz wireless connections over the years. Now, Samsung is investigating Ultra Wide-Band (UWB) for wireless earphones.
91mobiles spotted a Samsung patent for wirelessly transmitting audio between a device and wireless earphones via UWB. The patent, which was published yesterday (January 30) via the US Patent and Trade Office, reveals that Bluetooth is still used to initially establish a connection between the host device and the first earphone. However, the first earphone then switches to a UWB connection, followed by the second earphone. Audio transmission then takes place via UWB too. Check out the diagram below.
