The JBL Tune Flex Ghost Edition is a pair of wireless in-ear headphones featuring a distinctive transparent casing that reveals the internal components. These earbuds use 12mm dynamic drivers to deliver the signature JBL Pure Bass Sound across a frequency range of 20 Hz to 20,000 Hz, making them a versatile choice for music lovers who appreciate a deep low-end. To help you stay connected to your surroundings, the device includes Active Noise Cancelling along with Ambient Aware and TalkThru technologies, allowing you to switch between total immersion and hearing the world around you without removing the buds. Designed for daily activity, the plastic build is IPX4 rated, which means they can handle sweat and light splashes of water during a workout or a commute. You can manage your audio and touch controls through the JBL Headphones App, which also includes a feature to help you find your earbuds if they go missing. Four integrated microphones and VoiceAware technology ensure your voice remains clear during calls, while Bluetooth 5.2 provides a stable wireless connection up to 10 meters. Battery life varies depending on your settings, offering up to 32 total hours of playback with ANC off, or 24 hours when noise cancellation is active. The included USB Type-C charging case replenishes the buds in about two hours, though a quick 10-minute charge provides two hours of listening time. Weighing only 48.2 g, these lightweight earbuds are comfortable for extended wear throughout the day.
