Samsung recently unveiled the Galaxy Buds On , its first wireless earbuds with Bluetooth 6.2 . While this is one of the newest versions of Bluetooth available right now, an even newer iteration has been announced, and it could bring truly lossless audio and more to future Galaxy Buds.
Bluetooth 7.0 with HDT supports up to 7.5Mbps bitrate over LE
The Bluetooth Special Interest Group (SIG), which oversees the development of Bluetooth technology, has announced the formal adoption of Bluetooth High Data Throughput (HDT) as an optional feature in Bluetooth Core 7.0. It increases the maximum bit rate of Bluetooth Low Energy (LE) from 2Mbps to 7.5Mbps, nearly quadrupling the data transfer speed. This not only allows for truly lossless audio but also brings several other improvements.
Lossless audio requires a bitrate of at least 1.4Mbps, unless a proprietary codec like aptX Lossless is used. For Hi-Res Lossless Audio, a bitrate of 4.5Mbps is needed, and Bluetooth 7.0 HDT more than satisfies that requirement.
In addition, the upcoming standard can transfer advanced audio features like spatial audio and multichannel surround sound without relying on proprietary wireless protocols. Devices w...
