They carry an IP54 ingress protection rating, making them sweat resistant for active use. Stereo speakers are present, while features such as RGB lighting, a UV light, and an on-device display are not part of the design.
The JBL Wave Buds 2 include both active noise cancellation and passive noise reduction, offering two layers of isolation from ambient sound.

Spatial audio, Dolby Atmos, and Dirac Virtuo are not supported, and the drivers do not use a neodymium magnet.
The JBL Wave Buds 2 offer 10 hours of battery life per charge, which drops to 8 hours when active noise cancellation is enabled. The charging case holds 550 mAh and extends total playback to 30 hours, while each earbud carries a 49 mAh battery.
