About Apple lossless audio

Can you listen to Apple Lossless audio with your Bose headphones?

The short answer is: yes, using a wired connection. Bluetooth connections don’t support lossless audio. The same applies to every brand of headphones on the market.
 

Please read on for a more in depth explanation on Apple Lossless audio compression ...



What is lossless audio compression?

Most audio compression techniques lose some amount of data contained in the original source file. Lossless compression is a form of compression that preserves all of the original data.

Apple has developed its own lossless audio compression technology called Apple Lossless Audio Codec (ALAC). In addition to AAC, the entire Apple Music catalog is now also encoded using ALAC in resolutions ranging from 16-bit/44.1 kHz (CD Quality) up to 24-bit/192 kHz.

While the difference between AAC and lossless audio is virtually indistinguishable, Apple Music subscribers have the option to access music in lossless audio compression.
 


How to listen to lossless on your iPhone or iPad

What you need:
You can listen to lossless on an iPhone or iPad updated to iOS or iPadOS 14.6 using:
  • A wired connection to headphones, receivers, or powered speakers
  • The built-in speakers
  • To listen to songs at sample rates higher than 48 kHz, you need an external digital-to-analog converter


FAQs

Can I listen to lossless audio over Bluetooth?
Apple will deliver music using lossless audio compression to your iPhone, iPad, Mac, and Apple TV. Lossless will play back normally on Bluetooth speakers and headphones. However, Bluetooth connections don’t support lossless audio.
 
Can I listen to lossless audio using Apple’s Lightning to 3.5 mm Headphone Jack Adapter?
Yes. The Lightning to 3.5 mm Headphone Jack Adapter is designed to transmit audio from the iPhone’s Lightning connector. It contains a digital-to-analog converter that supports up to 24-bit/48 kHz lossless audio. To listen to songs at sample rates higher than 48 kHz, you need an external digital-to-analog converter.
