3. സജ്ജീകരണം
3.1 നിങ്ങളുടെ ഹെഡ്ഫോണുകൾ ബന്ധിപ്പിക്കുന്നു
The DT 990 PRO headphones feature a fixed single-sided coiled cable terminating in a 3.5mm (1/8") stereo jack. For compatibility with professional audio equipment, a 6.35mm (1/4") screw-on adapter is included.
- Identify the audio output port on your device (e.g., audio interface, mixing console, amplifier, computer).
- If your device has a 3.5mm jack, plug the headphone cable directly into the port.
- If your device has a 6.35mm jack, screw the provided 1/4" adapter onto the 3.5mm plug of the headphone cable, then insert it into the device's audio output.
പ്രധാന കുറിപ്പ്: The DT 990 PRO 250 ohm version has a high impedance. For optimal performance and volume, it is highly recommended to use these headphones with a dedicated headphone amplifier or an audio interface/mixing console with a powerful headphone output. Connecting directly to low-power devices like some smartphones or laptop headphone jacks may result in lower volume and reduced audio quality.

4.1 ഹെഡ്ഫോണുകൾ ധരിക്കൽ
The DT 990 PRO headphones are designed for over-ear wear, with circumaural ear pads that fully enclose the ears. This design, combined with the soft velour ear pads and extra-lightweight construction, ensures high wearing comfort even during long studio sessions.
- Adjust the headband to ensure a secure yet comfortable fit on your head. The flexible band design adapts to various head sizes.
- Ensure the ear pads sit evenly around your ears to maximize sound isolation and comfort.

4.2 Open-Back Design Characteristics
The DT 990 PRO features an open-back design, which contributes to its characteristic spacious and transparent sound. This design allows for a more natural soundstage, making them ideal for critical listening and precise audio placement in a mix.
- Spatial Definition: The open design provides outstanding spatial definition and detailed depth gradation, allowing you to accurately perceive the position of instruments and vocals in a stereo field.
- ശബ്ദ ചോർച്ച: Due to their open nature, these headphones will allow sound to leak out and ambient noise to enter. They are best used in quiet studio environments where sound isolation is not the primary concern.
