Bluetooth High Data Throughput raises the ceiling to 7.5 Mbps
The gain matters most for listeners who want uncompressed audio over a wireless link, though only some devices will support the top tier.
The Bluetooth Special Interest Group has introduced High Data Throughput, a feature that raises the ceiling to 7.5 Mbps, nearly four times the 2 Mbps of Bluetooth LE 2M. The extra capacity is aimed at data-heavy uses such as AI, spatial computing and extended reality, and at lossless audio, which earlier Bluetooth versions could not carry without compression. Because CD-quality audio needs roughly 0.8 to 1.4 Mbps, the new headroom could let audiophiles stream uncompressed sound wirelessly. Compliance with Bluetooth Core Specification 7.0 alone does not guarantee HDT, and the top 7.5 Mbps tier is optional, so buyers will need to check which tiers a device supports.
Why it matters
Earlier Bluetooth versions forced audio through lossy codecs because they could not carry lossless sound reliably. With High Data Throughput, a 24-bit 96 kHz stream fits within the new maximum, so wireless lossless listening becomes possible on compatible hardware. Higher-resolution formats at 192 kHz still exceed the limit. Because the 7.5 Mbps tier is optional and meeting Core Specification 7.0 does not guarantee the feature, buyers will need to check which tiers a given device supports before assuming it can play lossless audio.
