True Wireless Earbuds with ANC

The JBL Tune Flex are true wireless earbuds finished in blue. They deliver JBL Pure Bass Sound and feature Active Noise Cancelling with Smart Ambient technology for adjustable isolation. Four built-in microphones provide clear calls and VoiceAware control. The light stick open design aims to balance secure fit with natural sound awareness.

Battery life and environmental resistance

The charging case extends total listening time to 48 hours. An IPX4 rating protects the earbuds against sweat and rain during workouts or outdoor use. The ergonomic shape is intended for all-day comfort during sustained wear. Voice assistant integration allows hands-free control without interrupting longer sessions.

Check fit preference and device compatibility

The open stick design does not seal the ear canal like traditional silicone tips, so buyers who want maximum passive isolation should note this difference. Verify that your phone or laptop supports the required Bluetooth profiles for ANC toggling, multipoint pairing and voice assistant features.
