4. Wearing the Earbuds
Proper fit is crucial for comfort, sound quality, and secure wear, especially during physical activity.
Achieving a Comfortable and Secure Fit:
- Choose the Right Eartips: Experiment with the included silicone (S, M, L) and memory foam eartips to find the size that creates a comfortable seal in your ear canal. A good seal enhances bass response and noise isolation.
- Position the Earbuds: Gently insert the earbud into your ear canal.
- Adjust the Over-Ear Hook: Guide the flexible ear hook over the top of your ear. The hook should rest comfortably behind your ear, securing the earbud in place.
- Use the Shirt Clip: Attach the included shirt clip to your clothing to minimize cable movement and reduce microphonics (noise from cable rubbing).
