Burn In

Burn-in is the process for exercising new audio equipment. Most headphones require at least 40 hours of burn-in time to reach their optimal performing state.

The main purpose of the burn-in process is to loosen the diaphragm of a newly crafted headphone and to stress the headphone driver. Most audiophiles agree that the sound quality will be noticeably improved after burn-in.

How do I do it?

There are different ways to burn-in your headphones (or earbuds). The most common ways include running a variety of music, white noise, pink noise, radio noise, frequency sweeps, etc. through the headphones at a medium volume. Note: too high of a volume can cause damage to, or even kill your headphones!

There are no statistics stating which method works best. Music is an obvious burn-in candidate and works quite well if you have a broad range of musical genres in your playlist. Playing only one type of music however will not exercise and stress the entire audio spectrum.

How long should I do it?

The general rule is about 40 hours. Some people burn-in their headphones quickly playing them 40 hours continuously after bringing them home. This may not be good because, the diaphragm may be too weak at this time and should not be pushed to the limit. The best thing to do may be to plug your headphones into your computer or mp3 player, set the volume to medium, and let your music play for up to 4-5 hours a day for 5 days (perhaps, while you are at work or sleeping). After that, your headphones will most likely sound their best. Note: you do not need to listen the whole time. JLab has provided a simple burn-in method for your convenience. Use it at your own risk, as JLab will not be responsible for any damage to electrical equipment or human ears.

Directions for use:

Please connect your headphones to your computer, remove them from your ears, turn the volume to mid-level (medium), press play on the player below, and let it play for the desired time.

Do not listen to your headphones while the burn-in file is playing!

The audio burn in file contains a nonstop loop of: White noise, pink noise, radio white noise, 20-20000 Hz frequency sweeps, 10-30000 Hz frequency sweeps, 20-200 Hz frequency sweeps, as well as a minute of silence in between each for a rest period.
