However, one question that has been on many audiophiles’ minds is: are AirPods lossless? In this article, we’ll delve into the world of audio compression, explore the technology behind AirPods, and uncover the truth behind their sound quality.
Understanding Lossless Audio
Before we dive into the world of AirPods, it’s essential to understand what lossless audio means. Lossless audio refers to a digital audio format that retains all the original audio data, without any compression or loss of quality. This means that the audio signal is transmitted in its purest form, without any degradation or alteration. Lossless audio formats, such as FLAC, ALAC, and WAV, are highly prized among audiophiles for their ability to deliver crystal-clear sound that’s faithful to the original recording.
The Impact of Compression on Audio Quality
On the other hand, compressed audio formats, such as MP3 and AAC, use algorithms to reduce the file size of the audio data. This compression process discards some of the audio data, resulting in a loss of quality. While compressed audio formats are convenient for streaming and storage, they can compromise the sound quality, introducing artifacts and degrading the overall listening experience.
How AirPods Handle Audio Compression
So, how do AirPods handle audio compression? The answer lies in the technology behind Apple’s wireless earbuds. AirPods use a combination of Bluetooth and Apple’s proprietary W1 (or H1) chip to transmit audio signals from your device to the earbuds. When you stream music from your iPhone or iPad to your AirPods, the audio signal is compressed using the AAC (Advanced Audio Coding) format.
AAC: The Compression Format Used by AirPods
AAC is a lossy compression format that’s designed to balance file size with sound quality. While AAC is generally considered to be a high-quality compression format, it’s still a lossy format that discards some of the audio data. However, AAC is also capable of delivering high-quality audio at relatively low bitrates, making it a popular choice for streaming services and wireless earbuds.
Bitrate: The Key to Understanding AAC’s Sound Quality
The bitrate of an AAC file determines the amount of audio data that’s discarded during compression. A higher bitrate generally results in better sound quality, while a lower bitrate can compromise the sound quality. AirPods typically use a bitrate of around 256 kbps, which is relatively high compared to other wireless earbuds.
Are AirPods Lossless?
So, are AirPods lossless? The answer is no. While AirPods use a high-quality compression format like AAC, they still rely on compression to transmit audio signals. This means that some of the audio data is discarded during transmission, resulting in a loss of quality.
But What About Apple’s Lossless Audio Format?
In 2021, Apple announced its own lossless audio format, called ALAC (Apple Lossless Audio Codec). ALAC is a lossless format that’s designed to deliver high-quality audio without any compression or loss of data. However, ALAC is not currently supported by AirPods, and it’s unclear whether future generations of AirPods will support this format.
Conclusion: Are AirPods Good Enough?
While AirPods may not be lossless, they still deliver impressive sound quality that’s good enough for most music lovers. The AAC compression format used by AirPods is capable of delivering high-quality audio at relatively low bitrates, making it a great choice for wireless earbuds.
Who Needs Lossless Audio, Anyway?

Are AirPods truly lossless, and what does that mean for audio quality?
Lossless audio refers to a digital audio format that preserves the original audio data without any loss or compression. In the case of AirPods, they do not support true lossless audio. While they can stream high-quality audio, the Bluetooth technology used in AirPods compresses audio files, which can result in a loss of detail and dynamic range. This compression is necessary to ensure reliable and efficient wireless transmission.
However, it’s worth noting that the human ear may not be able to perceive the difference between lossless and compressed audio in many cases. AirPods use the AAC (Advanced Audio Coding) codec, which is designed to provide a good balance between audio quality and compression. While audiophiles may notice a difference, the average listener may not be able to tell the difference between lossless and compressed audio on AirPods.
What is the difference between lossless and Hi-Fi audio, and how does it relate to AirPods?
Lossless audio and Hi-Fi audio are often used interchangeably, but they are not exactly the same thing. Hi-Fi audio refers to high-fidelity audio, which is a broader term that encompasses a range of audio formats and qualities. Lossless audio, on the other hand, specifically refers to digital audio formats that preserve the original audio data without any loss or compression. AirPods do not support true lossless audio, but they can stream Hi-Fi audio using the AAC codec.
However, it’s worth noting that the term “Hi-Fi” is often misused in the context of wireless earbuds like AirPods. While AirPods can stream high-quality audio, the limitations of Bluetooth technology and the AAC codec mean that they may not be able to deliver the same level of audio fidelity as wired headphones or high-end audio equipment. Nevertheless, AirPods are still capable of delivering high-quality audio that is enjoyable to listen to.
Can AirPods stream lossless audio using Apple’s ALAC format?
Apple’s ALAC (Apple Lossless Audio Codec) format is a lossless audio format that preserves the original audio data without any compression. However, AirPods are not capable of streaming ALAC audio directly. This is because the Bluetooth technology used in AirPods is not compatible with the ALAC format. Instead, ALAC files are converted to AAC or another compatible format before being transmitted to AirPods.
However, it’s worth noting that Apple devices can convert ALAC files to AAC or another compatible format on the fly, so you can still listen to ALAC files on AirPods. The conversion process is transparent to the user, and the resulting audio quality is still high. Nevertheless, audiophiles may notice a difference between the original ALAC file and the converted AAC file.
How does Bluetooth compression affect the audio quality of AirPods?
