3.2 Eartip Selection and Installation
Proper eartip selection is crucial for optimal noise isolation and comfort. The ISOtunes Xtra 2.0 comes with both foam and silicone eartips in various sizes.
- Select the correct size: Experiment with different sizes to find the tips that provide a snug, comfortable fit and seal your ear canal effectively.
- For foam eartips: Roll the foam tip between your fingers to compress it into a thin cylinder. Insert the compressed tip into your ear canal and hold it in place for a few seconds while it expands to create a seal.
- For silicone eartips: Gently insert the silicone tip into your ear canal until it feels secure and comfortable.
