Bluetooth LE gets support for High Data Throughput (HDT)
It boosts the standard’s maximum supported bit-rate by almost four times
That means support for hi-res audio, spatial audio and multi-channel audio
Good news for the best headphones of 2027 and beyond: the latest Bluetooth technology includes High Data Throughput technology, HDT for short, which gives Bluetooth LE a huge performance boost. It can transmit almost four times as much data as the current version, enabling it to send hi-res audio, spatial audio and multi-channel audio to other devices. The fact that HDT is part of Bluetooth is important, because that means you aren’t reliant on a proprietary technology for your hi-res music: if manufacturers choose to use HDT, which we’d expect them to do, then you’ll have compatibility across a huge range of headphones, Bluetooth speakers and other home entertainment hardware. There are other benefits too, as many current hi-res audio streams are sent via Wi-Fi rather than Bluetooth. Sending them over Bluetooth LE removes that traffic from your home network, potentially cutting down on congestion, and it is likely to boost your headphones’ battery life, too. Faster data transfer means less work for your Bluetooth radio, whether you’re listening to hi-res audio or lower-res streams. What’s new in the blue
A new version of Bluetooth is always welcome, but it’ll be a few months before Bluetooth 7…
