The JBL Vibe Beam 2 feature an in-ear fit and a fully true wireless design, meaning there are no cables or neckband to contend with. Each earbud weighs just 8.6 g, keeping the physical footprint minimal. The earbuds carry an IP54 ingress protection rating, making them sweat resistant and suitable for use during physical activity. Stereo playback is supported, while wingtips, RGB lighting, a UV light, and a display are all absent from the design.
The JBL Vibe Beam 2 use an 8 mm driver unit with a frequency range spanning 20 Hz to 20,000 Hz, an impedance of 16 Ohms, and a sound pressure level of 95 dB/mW. Passive noise reduction is present to help attenuate ambient sound, though active noise cancellation is not supported. The earbuds do not include spatial audio, Dolby Atmos, Dirac Virtuo, or a neodymium magnet.
Each earbud holds a 50 mAh rechargeable battery delivering up to 10 hours of playback per charge, while the 550 mAh charging case extends total listening time to 30 hours. A full charge takes 2 hours, and a battery level indicator is available to keep track of remaining power. Wireless charging and solar power are not supported. The specs also list an 8-hour battery life figure associated with ANC conditions, though this applies to a mode the earbuds do not actively support.
The JBL Vibe Beam 2 connect wirelessly via Bluetooth 5.3 with a maximum range of 10 m, and fast pairing is supported for quicker device setup. USB Type-C is used for wired charging. The earbuds do not support any aptX variant — including aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, or aptX Voice — nor do they include LDAC, LDHC, AAC, Bluetooth LE Audio, Auracast, or NFC pairing.
The JBL Vibe Beam 2 support multipoint connectivity for up to two devices simultaneously and can be used as a headset, with a mute function available during calls. Fast charging is supported, and a find-device feature helps locate misplaced earbuds. Controls are handled via a panel placed on the device itself rather than an in-line control panel, and voice prompts provide audio feedback. A travel bag is included in the package. Ambient sound mode, in/on-ear detection, notification reading, a body temperature sensor, and a camera remote shutter function are all absent.
The JBL Vibe Beam 2 include a four-microphone array with noise-canceling capability, helping to reduce unwanted background sound during calls and voice interactions.
