A plastic enclosure measuring 3.85 by 2.5 by 0.58 inches and weighing 0.041 kg fits easily in a pocket or on a dashboard mount. The integrated 3.5 mm female-to-female jack provides a direct wired link while the internal lithium-ion battery powers portable use. A single multifunction button handles pairing, playback, volume and hands-free calls through the built-in microphone.

Bluetooth 5.4 Range And Battery Limits

Bluetooth 5.4 delivers stable pairing and up to 33 ft of wireless range in open conditions. The rechargeable cell stores roughly 1 Wh of energy and requires a full charge before first use. Audio quality and connection stability depend on line-of-sight and the capabilities of the paired source or sink device.
