-DO NOT TURN VOLUME ALL THE WAY UP WITH BRAND NEW SOUND EQUIPMENT-
Research “Burn-In”… It’s the term used for audio speakers, including headphones and the like, describing proper break-in for the sound drivers. Some speakers can take 100’s to 1000’s of hours of sound projection before they start to reach their Peak Sound Quality. In other words, if you treat them as you should and keep the volume well below maximum during Burn-In, the audio will get better & better. Putting your device into it’s prime, instead of the trash.
