Please note that audio artifacts such as white noise, hissing, static, or buzzing can occur in speakers or headphones designed with batteries and active electronics. This is commonly referred to as a “noise floor.” It is a normal characteristic of this type of audio equipment and is typically only noticeable in very quiet environments when the power is on but no audio source is playing.
