En funcionament
Once connected and adjusted, your HD 518 headphones are ready for use:
- Portada: Ensure the earcups fully encompass your ears. The open-back design allows for a more natural and spacious sound, but also means some sound will leak out and external sounds may be audible. This is characteristic of open-back headphones and contributes to their wide soundstage.
- Control de volum: Adjust the listening volume directly from your connected audio source (e.g., amplifier, computer, smartphone). The HD 518 headphones do not feature inline volume controls.
- Entorn d'escolta: For the best experience, use these headphones in a quiet environment where the open-back design can be fully appreciated without disturbing others or being disturbed by external noise.
