News that Bluetooth has officially adopted its new High Data Throughput (HDT) specification should be music to audiophile ears far and wide. And there’s a good chance your future pair of wireless headphones could sound considerably better as a result.
If you missed the announcement, Bluetooth HDT extends the capabilities of Bluetooth Low Energy (LE), boosting its maximum physical-layer data rate (PHY, pronounced “fie”) from 2Mbps to a comparatively colossal 7.5Mbps. That’s almost four times the maximum rate of conventional Bluetooth LE, and 2.5 times faster than Bluetooth Enhanced Data Rate (EDR), which tops out at 3Mbps.
