Bose - Fit Kit for QuietComfort Earbuds II - Eclipse Gray

Bluetooth wireless connection

The Bose QC Earbuds II Fit Kit contains silicone eartips and stability bands to replace the originals in the event that you need new ones. The Bose QC Earbuds II Fit Kit includes 3 different pairs of soft eartips (S, M, L) and 3 different pairs of stability bands (1, 2, 3) to mix and match to find your best fit. The eartips rest gently but securely in your ears and spread contact evenly, creating a comfortable seal that is important to delivering the best audio performance and the most powerful noise cancellation. The stability bands hug the contours of the outer parts of your ear, ensuring that the earbuds stay in place.
