The JBL TUNE FLEX features active noise canceling and offers up to 24 hours of battery life. Product Description ■ Two-way design allows you to choose between a "open-ear" style for a light fit and a "sealed-ear" style for high sound isolation. By changing the ear tips, you can choose between the "open-ear" style, which hooks into the entrance of your ear, and the "sealed-ear" style, which inserts the earphone body into your ear, allowing you to use them according to your preference. This is JBL's first two-way design. The "open-ear" style is characterized by its light fit even after long hours of use, without a feeling of pressure, and a shape that makes it easy to hear the surrounding sounds. It can be used casually even by people whose ears don't fit the earphones due to their shape or size. In addition, the sound spreads well from the mid to high frequencies, and you can enjoy a refreshing sound quality, which is also a charm of the "open-ear" style. In contrast, the "sealed-ear" style is characterized by its excellent fit and high sound isolation, allowing you to directly experience the powerful bass. Combined with the active noise canceling function, you can enjoy music without worrying about the 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 have wireless earphones, you can use them in your daily life by switching between them. ■ 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.
