The jury is still out on whether or not AAC sounds as good as aptX but one thing is certain: both codecs are lossy (no matter Qualcomm’s slippery tech talk) and both sound better than SBC, to varying degrees depending on the hardware implementation. In aptX’s place, Apple have gone with AAC as their optional Bluetooth audio codec for iOS. aptX must be present in both headphone and transmitting device (phone, tablet, PC, Mac) for it to handle the data compression required by a Bluetooth audio connection. ![]() And not only because iOS gives us no way to tell which audio codec is being used to bridge smart device and Bluetooth headphone but because Apple elected not to include aptX (HD) in its iOS devices (despite putting it in Macbooks and iMacs). But how?Īt time of writing, the short answer is: you can’t. As an iOS user you want to make sure aptX (HD) is in play when sending music via Bluetooth from your iPhone or iPad to your new headphones.

Has the manufacturer made a big noise about aptX (HD) support on the packaging? aptX developer Qualcomm asserts that their Bluetooth codec provides “wired quality sound – wirelessly.” Understandably, you want some of that good stuff. ![]()
