Does XM5 support AAC?

Sony’s WH-1000XM5 headphones, the eagerly awaited successors to the WH-1000XM4, are expected to offer an array of features designed to enhance your listening experience. Among these features is support for audio codecs, including AAC. In this article, we will explore what AAC is, why it’s important, and whether the Sony WH-1000XM5 headphones are likely to support it.

Understanding AAC

AAC, or Advanced Audio Coding, is an audio codec that was developed to provide high-quality audio compression. It is considered a significant advancement over older codecs like MP3. AAC is particularly known for its ability to deliver excellent sound quality while maintaining a relatively small file size. This makes it a popular choice for streaming and storing high-quality audio on various devices.

Key Features of AAC:

  1. High Audio Quality: AAC is known for its ability to preserve audio quality, even at lower bitrates, making it ideal for delivering clear and detailed sound.
  2. Efficient Compression: AAC’s efficient compression algorithm allows it to produce smaller file sizes while maintaining high audio quality, which is crucial for streaming and storing audio files.
  3. Widespread Compatibility: AAC is a widely supported codec, making it compatible with a vast range of devices, including smartphones, tablets, computers, and headphones.
  4. Low Latency: AAC typically offers lower audio latency compared to some other codecs, which is beneficial for tasks like video streaming or gaming where audio synchronization is essential.

Sony WH-1000XM5 and AAC

As of my last knowledge update in September 2021, Sony’s WH-1000XM4 headphones supported the AAC codec. Given the industry-standard nature of AAC and Sony’s commitment to delivering high-quality audio, it is reasonable to expect that the Sony WH-1000XM5 headphones will continue to support AAC.

The inclusion of AAC support is advantageous for users who own Apple devices, as AAC is the default audio codec for Apple’s ecosystem. This ensures seamless and high-quality wireless audio streaming when using the headphones with iPhones, iPads, and other Apple products.


While specific details about the Sony WH-1000XM5 headphones will be officially disclosed upon their release, it is highly likely that these headphones will support the AAC audio codec. This support ensures that users can enjoy high-quality audio streaming, especially when paired with Apple devices, and benefit from the excellent sound quality that AAC delivers. As always, it is advisable to consult the official product documentation for precise information regarding audio codec support once the WH-1000XM5 headphones are officially released.
