The Gembird TWS-ANC-MMX wireless earbuds in black are designed for mobile phone users who want to isolate themselves from environmental noise. These black ABS plastic headphones feature active noise cancellation and dynamic drivers that cover a frequency range from 20 Hz to 20,000 Hz, ensuring a balanced sound profile with a sensitivity of 118 dB SPL/mW. Connectivity is handled via Bluetooth 5.0, which maintains a stable wireless link up to 10 meters. For daily use, the integrated microphone allows for hands-free calls, while an LED indicator keeps you informed about the device status. The lightweight design, weighing only 34 g, makes them comfortable for extended wear during commutes or work. Power is provided by a 300 mAh Li-Polymer battery that offers up to 8 hours of playback on a single charge. When the battery runs low, you can use the included charging case and a USB Type-C cable to fully recharge the earbuds in about 2 hours.
