The Lenovo E310 True Wireless Stereo earbuds provide a cord-free listening experience powered by Bluetooth 5.3, ensuring a stable wireless connection within a 10-meter range. These black earphones are designed for clarity, featuring a frequency range from 50 Hz to 20,000 Hz and a sensitivity of 114 dB SPL/mW with 32 Ohm impedance. To help you stay heard during calls, the system utilizes dual microphones and Environmental Noise Cancellation (ENC) to reduce background interference. Managing your audio is intuitive thanks to integrated touch controls that let you handle playback and respond to calls without reaching for your phone. The earbuds are lightweight at 33.6 g and come with a charging case featuring a 280 mAh battery, providing up to 20 hours of total playback time. When power runs low, the USB Type-C port allows for a full recharge in about 2 hours, while a built-in LED indicator keeps you informed about the battery status.
