The Bluetooth Special Interest Group (SIG) that oversees the wireless standard has formally adopted Bluetooth High Data Throughput (HDT) as an optional feature of the Bluetooth Core 7.0. It’s an upgrade the Bluetooth SIG has been previewing over the past year that increases Bluetooth LE’s maximum supported bit rate from 2 Mbps to 7.5 Mbps. It will allow for higher resolution audio to be streamed but also improvements to battery life and reliability.
The primary application for Bluetooth HDT will once again be for wireless audio, with the first devices supporting the new feature expected to appear sometime in 2027. The increased bit rate will support high-resolution audio but also new wireless audio experiences including spatial audio and multi-channel surround sound without requiring proprietary wireless formats.
Bluetooth HDT will benefit other wireless devices beyond headphones. Smartwatches could sync more training, health, and fitness data to a phone without a reduction in battery life because HDT can transfer more data in less time, requiring the Bluetooth radio to be on for shorter periods. Spatial computing and extended reality devices could offer more robust experiences without needing a connection to Wi-Fi, and HDT will benefit the ever-growing number of personal AI devices, allowing them to more efficiently hand off data to be processed by a smartphone so they can be lighter and smaller.
