Operating Instructions
1. Wearing the Headphones
- Identify the "L" (Left) and "R" (Right) markings on the inside of the headband or earcups.
- Place the headphones over your ears, ensuring the earcups fully enclose your ears for optimal sound isolation and comfort.
- Adjust the headband length by sliding the earcups up or down until a comfortable and secure fit is achieved. The headband should rest gently on the top of your head.
2. Volume Control
Volume is controlled directly from your connected audio source (e.g., mixing console, audio interface, computer, smartphone). Adjust the volume to a comfortable listening level. Prolonged listening at high volumes can cause hearing damage.
3. Sound Monitoring
The DT 250 headphones are designed for accurate and balanced sound reproduction, making them ideal for critical listening, mixing, and monitoring tasks. Their closed-back design minimizes sound leakage and provides good passive noise attenuation, allowing you to focus on your audio without distraction.
Maintenance
1. Cleaning
- Wipe the exterior of the headphones with a soft, dry cloth.
- For earcups, gently wipe with a slightly damp cloth. Avoid using harsh chemicals or abrasive cleaners.
- Ensure no moisture enters the earcup drivers.
2. Storage
When not in use, store the headphones in the provided carrying bag to protect them from dust and physical damage. Avoid storing in extreme temperatures or high humidity.
