ISOtunes Sport ADVANCE comes with 3 sets of ISOtunes TRILOGY Foam eartips (S,M,L) and 1 set of rubber triple flange eartips.
The device comes with the Medium size eartips already in place. Choose the eartip size that fits most snugly in your ear canal. Remember, the snugger the fit, the better the noise attenuation. To do so, follow the steps below:
1. Start by placing the headphones around the back of your neck, and ensure you have the proper earbuds on each side of your head (right vs. left).
2. Grab the right earbud with your right hand and use your left hand to warm up and compress the foam eartip.
3. Before inserting the compressed foam eartip into your ear, reach over your head with your left hand and lift the top of your right ear to open your ear canal.
4. Then, insert the foam eartip deeply into your ear canal and hold it in place for 5 seconds, or until the foam has fully expanded.
5. Finally, press and bend the memory wire behind your ear to get your desired fit, and ensure the earbud is flush with the outside of your ear.
6. Repeat steps 2 through 5 with the opposite earbud.
