Ultimate Ears earned its reputation for outstanding audio reproduction with custom-made, in-ear stage monitors worn by some of the world's most prominent musicians. With the UE Fits, they've somehow managed to bring this same idea to true wireless earbuds. Using Lightform technology, their tips mold to perfectly fit the wearer's ear in just 60 seconds, ensuring a comfortable, secure fit and superior noise isolation. The sweat-proof 'buds also offer Bluetooth 5.0, integrated mics for clear calls, tap controls, and 8 hours of battery life, extended to 20 hours via the protective charging case. Shipping later this fall.
