The impedance rating of your headphones influences how much power they require:
- Low Impedance (16-32 ohms): Suitable for mobile devices and audio interfaces as they require less power to deliver high volume.
- High Impedance (above 250 ohms): Designed for professional use requiring dedicated headphone amplifiers for adequate sound levels.
Checking Compatibility
Before setting up your dual headphone configuration, it’s crucial to ensure compatibility with your audio interface and headphones.
Interface Output Types
Understand the output options available on your audio interface:
- 1/4 inch TRS: Common in professional audio equipment and offers stereo sound, ideal for high-quality headphones.
- 1/8 inch TRS (3.5mm): Standard size for consumer headphones.
Verify Headphone Input Types
Make sure your headphones match the interface output. If you have 1/8 inch headphones and your interface only has 1/4 inch outputs, you will need an adapter.
Real-World Application and Tips
Here are some practical tips to get the most out of connecting two headphones to an audio interface.
Mixing Techniques
When using two headphones, ensure that both users are positioned correctly to monitor the sound accurately. Pay attention to reflections, as they can affect the perceived audio quality.
- Mixed Session Setup: In a collaborative session, encourage both listeners to communicate and share feedback. After making adjustments instruct one another to switch between headphones for a fair comparison.
- Volume Balance: Be mindful of the volume levels to prevent fatigue and ear discomfort after prolonged sessions.
Routine Maintenance
Regularly check connections, as wear and tear can cause unwanted noise or audio dropouts. Always keep your headphone cables in good condition and use cable organizers to prevent tangling and damage.
