Custom Fit
Achieving the optimal fit is crucial for both comfort and sound quality. The JBuds Pro offer multiple customization options:
- Adjustable Tip Placement (ATP): This patent-pending feature allows you to adjust the depth of the earbud tip within your ear canal. Experiment with different depths to find a relaxed fit or a sound-sealing fit that blocks out external noise.
- Cush Fin Technology: Two sizes of Cush Fins are included. These soft, flexible fins provide extra support and help lock the earbuds into your ear, preventing them from falling out during movement.
- Gel Ear Tips: Three sizes of silicone gel tips (Small, Medium, Large) are provided. Select the size that creates a comfortable seal in your ear canal for the best audio performance and noise isolation.
