The Panasonic RZ-B110WDG are true wireless in-ear headphones designed for a comfortable, secure fit thanks to their Ergofit shape. These black earbuds feature 10 mm dynamic drivers and XBS technology, which enhances the lower frequencies to provide a richer bass experience across a frequency range of 20 Hz to 20,000 Hz. With a sensitivity of 118 dB and an impedance of 20 Ohm, they deliver clear audio via Bluetooth 5.3, supporting both SBC and AAC codecs for a stable connection within a 10-meter range. Built for active daily use, the plastic body and silicone tips are paired with an IPX4 rating, making them resistant to sweat and splashes. You can manage your music, take calls through the integrated omnidirectional microphone, or activate your voice assistant using the touch controls. The device is powered by Li-Polymer batteries, offering 6 hours of playback on a single charge, which extends to a total of 26 hours when using the 400 mAh charging case. Charging is convenient through the USB Type-C port or via wireless charging, taking about 2.5 hours to reach full capacity. Weighing only 42.4 g, these headphones are easy to carry and suit anyone looking for a reliable wireless audio solution for commuting or exercise. The package includes the earbuds, the charging case, and a USB-C cable.
