Product Overview
Bose QuietComfort Ultra Earbuds are the ultimate wireless noise cancelling earbuds for a truly immersive listening experience. These high-quality wireless earbuds feature breakthrough spatialized audio for a deeper level of immersion that makes your music feel more real than ever before — no matter the content or source. Bose Immersive Audio pushes the boundary even further and takes what you’re hearing out of your head and places it in front of you for the most natural listening in a pair of spatial audio earbuds. And Bose CustomTune technology takes it to another level by analyzing your ear’s shape and adapting the sound and world-class noise cancellation so everything hits just as it should in your noise cancelling earphones. The comfort is shaped to you, too. With these Bose noise cancelling earbuds, you get nine combinations of eartips and stability band sizes to find the best fit. And up to 6 hours of playtime keeps your faves playing as long as you want to listen (up to 4 hours with Immersive Audio). Plus, the charging case (not included) holds up to three additional charges and a quick 20-minute charge gives you up to 2 hours of additional play time. These bluetooth wireless earbuds also feature advanced Bluetooth 5.3 so you can listen to your favorite tracks up to 30 feet away. Keep track of everything paired to the bluetooth earbuds using the Bose Music app which can also walk you through setup, lets you customize a shortcut, check battery levels, and access Adjustable EQ settings. Feel your music more with Bose QuietComfort Ultra Wireless Earbuds.
