True wireless earbuds with 32-hour battery

The JBL Tune Flex are true wireless earbuds that deliver JBL Pure Bass Sound through 12mm dynamic drivers. They feature Active Noise Cancelling with two microphones, plus Smart Ambient modes for awareness. Four microphones handle calls with VoiceAware control. Bluetooth 5.2 provides the wireless link and IPX4 rating resists sweat and splashes. The stick form factor sits securely for daily commutes and workouts.

Battery and noise cancelling over long sessions

With noise cancelling active you get 6 hours from the buds and 18 hours from the case, totalling 24 hours. Without noise cancelling the total rises to 32 hours, split as 8 hours in the buds and 24 hours in the case. A 10-minute speed charge adds 2 hours of playback. The 48-hour figure in the specifications reflects standby or combined usage scenarios not tied to continuous ANC playback.

Check fit and charging before ordering

The package includes three eartip sizes to seal the ear canal for bass response and noise isolation. Verify that your device supports Bluetooth 5.2 for full feature access. Charging uses the supplied USB Type-C cable; no wireless charging pad is included. Buyers who need on-ear comfort or longer single-charge playback without a case should consider other form factors.
