Operating Your Headphones
Wearing the Headphones
Position the headphones so that the earcups fully cover your ears. The adjustable headband allows for a personalized fit, ensuring comfort during prolonged listening. The open-back design means some sound will naturally escape and external sounds may be audible, contributing to a more natural soundstage.
Audio Source Connection
The headphones are designed for wired use. Connect the 3.5 mm jack to your audio device. The 38 Ohm impedance ensures compatibility with a wide range of devices without requiring a dedicated amplifier for most uses.
Volume Control
Adjust the volume directly from your connected audio source. The headphones do not feature inline volume controls.
