Setup
1. Selecting the Correct Ear Tips
Proper ear tip selection is crucial for optimal sound quality and comfort. The headphones come with four different sizes of ear tips (Small, Medium, Large, Extra Large). Experiment with each size to find the pair that provides a snug and comfortable seal in your ear canal. A good seal enhances bass response and noise isolation.
