3.1 Selecting the Correct Eartips
For optimal sound quality and comfort, it is crucial to select the correct size of silicone eartips. The package includes small, medium, and large sizes. Experiment with each size to find the one that creates a snug seal in your ear canal.
- A proper fit ensures superior sound isolation and enhanced bass response.
- If the eartips are too small, sound quality may be poor and external noise will not be adequately blocked.
- If the eartips are too large, they may cause discomfort.
