Bild © JLabJLab Flex Open in White 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.
These open-ear clip earbuds offer a lightweight, secure fit with 12mm dynamic drivers for decent sound at moderate volumes. They provide around 7 hours of playback per charge (21 hours with the case), Bluetooth 5.4 multipoint connectivity, and IPX4 sweat resistance, making them a budget-friendly option for workouts and daily use. Touch controls and a companion app with customizable EQ add convenience, though the lack of ANC and transparency modes may limit noise handling in loud environments.

Headphonecheck reports that the Flex performs well at higher volumes, with roughly 5.5 hours per charge in its own runtime test and just under 17 hours total with the case. It also lists Bluetooth 5.4, SBC and AAC codec support, a 12 ohm impedance, and 6 g weight per earbud.
Stiftung Warentest’s entry confirms the model and lists key traits such as IPX4 protection and a weight of about 12 grams. The detailed score is not visible in the provided result, so I cannot reliably extract a final rating from it.
