Change of sound quality after purchase is always possible
After purchasing Just ear, you can change your desired sound quality. There are two ways to update the sound quality. "Sound quality consulting" in which a Sony engineer tunes to the customer's desired sound quality in a face-to-face manner, and "Preset sound quality change" in which changes are made to three existing sound qualities: monitor, listening, and club. It can be customized according to the music you usually listen to and the change in sound quality you want.
