Bluetooth High Data Throughput adopted—audio standard expected in 2027

The Bluetooth Special Interest Group (SIG) announced the adoption of Bluetooth High Data Throughput (HDT) on November 4, 2026. The technology supports a maximum bit rate of 7.5 Mbps, but support is optional, so existing phones and earbuds are not guaranteed to gain it.

What 7.5 Mbps actually measures

HDT adds a new physical layer (PHY) for Bluetooth LE, with a maximum supported bit rate nearly four times that of the LE 2M PHY. Mbps measures millions of data bits per second; it does not describe audio sample rate or bit depth. The specified maximum does not guarantee real-world data throughput.

The SIG says HDT uses wireless spectrum more efficiently and can move data in less time, allowing the radio to spend less time transmitting and more time in low-power states. It also cites improved connection resilience and reliability. These are stated design benefits, not a promise of four times the sound quality or headphone battery life.

The audio standard is expected in 2027

HDT’s first flagship application will be a standard for premium wireless audio, expected to be released in 2027. The SIG says HDT provides the capacity and efficiency to support high-resolution and lossless audio, along with future multichannel surround and spatial audio.

That 2027 target concerns the audio standard, not a confirmed retail launch. The announcement names no consumer phone or headphone models or their release dates.

Check HDT support, not just the Bluetooth version

HDT is an optional feature of Bluetooth Core 7.0, so a Bluetooth 7.0 label alone does not guarantee it. For a future listening setup, look for explicit HDT support on both the phone and headphones, along with confirmation that they support the forthcoming audio standard. Do not assume a firmware update will add those capabilities to existing devices.
