Flex Open Earbuds Black

JLab Flex Open in Black are open-ear true wireless earbuds designed for listeners who want wireless audio without sealing the ear canal. The clip-on cuff design wraps around the outer ear with a flexible fit, leaving the ear canal completely open so ambient sound passes through naturally while you listen. A lightweight option for everyday use, working from home, outdoor activities, or anyone who finds in-ear canal earbuds uncomfortable during long wear sessions.

The 12mm dynamic driver delivers full-range sound from an open-ear form factor. EQ3 Sound gives you three preset listening modes: Signature, Bass Boost, and Balanced. Four MEMS microphones with 2-mic ENC handle call clarity. Touch controls for playback and calls. Movie Mode latency under 200ms for synced video.

Each earbud lasts 7 hours on a single charge with 21 total hours across the case. Quick charge gives you 1 hour of playback from 10 minutes of charging. The case charges via USB-C in under 2 hours. Standby time exceeds 60 hours.

Bluetooth 5.4 with SBC and AAC codecs. Both Google Fast Pair and Microsoft Swift Pair supported for instant pairing on Android and Windows devices. Multipoint connects to two devices simultaneously. Support protocols: HSP/HFP/A2DP/AVRCP. Compatible with iOS and Android, including Siri and Google Assistant. IP55 rated for dust and water resistance.

The JLab app adds custom EQ, control remapping, Music and Movie modes, OTA firmware updates, safe hearing tools, and My JLab device management.

Includes Flex Open earbuds and a JLab 2-year limited warranty.
