Can Bluetooth Transmit Lossless Audio?

Many sources will tell you that Bluetooth cannot transmit lossless audio. This has been true until recently, but we’re here to tell you that it’s now a possibility with Denon PerL Pro—the only personalized earbuds that support lossless audio over Bluetooth® wireless technology.

Why do others say lossless audio doesn’t work with Bluetooth? 

If you have earbuds or wireless earphones and connect to your device via Bluetooth, chances are you're listening to Lossy audio. This compressed audio format results in data loss and, consequently, poor sound quality. It saves space and speeds up wireless transmission, and most people can’t tell the difference between lossy and lossless files.

On the contrary, lossless audio is a much more faithful reproduction of the original audio recording. It can be transmitted wirelessly, but the bandwidth isn’t sustainable to do this over Bluetooth.

Articles like this in Android Authority and the supporting documentation for Apple products say you can't get lossless audio through Bluetooth. They also say it doesn't matter since no one would be able to tell the difference anyway, and lossy audio is good enough.

Why is lossless audio better? 

Lossless audio is the best form of audio as it has no drop in quality, and there is no data lost in the compression of the audio file. The audio you hear is as good as the source material.

If you have CD-quality audio, that's what you will experience. If you have Master Quality Authenticated files direct from a recording studio, that is the level of audio quality you will receive through lossless audio.

How does lossless audio work with Bluetooth?

To experience lossless audio through Bluetooth, you will need a device that supports Qualcomm aptX Lossless. Your device must use Qualcomm's Snapdragon Sound technology to transmit true CD-quality audio to your Bluetooth Denon PerL Pro earbuds .

New phones are being launched that support this technology, so if yours doesn’t yet, you’ll still have some awesome earbuds waiting for lossless audio.
