About Bluetooth® and aptX®

Our Bluetooth products easily connect to any of your devices that have Bluetooth, but to get the best sound possible we recommend using a device that supports Bluetooth aptX. Find out more about aptX here: csr.com/products/aptx

And if you’re looking for a new smartphone, tablet, or computer with aptX or want to look up your device and see if it supports aptX, go here to check out what’s available: aptx.com/products/browse/categories

And for iPad or iPhone users that don’t have aptX, don’t despair! MacOS (MacBook, iMac, Mac mini) include Bluetooth aptX, however if you use an iPhone or iPad, Apple generally uses the AAC codec and doesn’t support aptX. AAC sounds really good as well and you'll also get the extra benefit of our upsampling 24-bit DAC, so you won’t be disappointed by the sound quality if you use an iOS device with any of our Bluetooth products.
