3.2 Sådan tager du hovedtelefonerne på
For optimal lydkvalitet og komfort skal du sørge for, at hovedtelefonerne bæres korrekt:

4. Betjeningsvejledning
Once connected to an audio source, the Sennheiser HD6XX headphones are ready for use. Adjust the volume directly from your connected audio device. Due to their 300 Ohm impedance, these headphones benefit from a dedicated headphone amplifier for optimal performance and volume levels, especially with lower-power sources.
The open-back design provides a natural, spacious sound. Be aware that these headphones do not offer noise cancellation and will allow ambient sounds to pass through, while also allowing some sound to escape.
