The JBL TUNE FLEX features active noise canceling and boasts up to 24 hours of battery life. Product Description ■ Two-way design allows you to choose between a light "open-ear" fit and a highly sound-isolating "closed-ear" fit. This is JBL's first two-way design, allowing you to choose between an "open-ear" style that hooks into the ear canal and an "in-ear" style that fits snugly inside the ear, by swapping the ear tips. The "open-ear" style is characterized by its light fit, which is comfortable even after long periods of use, and its ability to let you hear ambient sounds. It's also a great option for those who find it difficult to find earbuds that fit their ears. In addition, the "open-ear" style offers a pleasant sound quality with a good spread of sound from the mid to high frequencies. In contrast, the "closed-ear" style offers a superior fit and high sound isolation, allowing you to directly experience the power of the bass. Combined with the active noise canceling function, you can enjoy your music without being disturbed by surrounding noise. The ear tips can be carried in the included dedicated case, so you can change them to suit your mood even when you're on the go, and you don't have to worry about losing them. Because of its convenience, even if you already own wireless earphones, you can use them in different ways to suit your daily life. ■ Equipped with Ambient Aware & TalkThru functions ■ Supports up to 32 hours of long playback and fast charging ■ Compatible with voice assistants and "Google Fast Pair" - Model Name: TUNE FLEX - Function: Active Noise Canceling - Bluetooth Version: 5.2 - Battery Life: Up to 24 hours - Special Notes: Requires removal of insulating tape Thank you for viewing.
