If you're used to wearing over-ear headphones, inserting the earbuds may feel strange at first. When you open your Bose wireless earbud packaging, you'll find an earbud charging case, two earbuds, a 12-inch (30 cm) USB-C (A to C) cable, and a Bose Fit Kit. The Fit Kit contains three pairs of eartips, including small, medium, and large, and three pairs of stability bands, numbered 1, 2, and 3.
With the right combination of tip sizes and stability bands, you’ll get the best fit from your new wireless earbuds. To find the right fit, you may need to experiment to see what fits your ears and feels the most comfortable. Start by pushing the small earbud tips onto the left and right earbud nozzles, being careful to note which side is which. Gently pull on the top of each ear to open the ear canal, and lightly insert the earbuds. See how they feel in your ears, and try each size of eartips. Be sure to push the earbuds all the way into your ears to achieve a proper seal with both ear canals. They should be snug, but comfortable.
