Thank you for visiting our shop (*^^*) Our product list #Yui's shop (ships on weekdays) Glazata EC200 Black Ultra-large capacity battery: * Built-in 260mAh large-capacity battery, * 30 hours of continuous talk time * 40 days of standby time * Effectively solves the power shortage of Bluetooth earphones, so you are not bound by music or calls. * If the paired mobile phone is not used for 10 minutes after turning off pairing, it automatically enters Deep Sleep mode, which saves power. * The CSR8615 smart chip Bluetooth processor has acoustic echo and noise reduction functions, and is equipped with an 80MIPS Kalimba DSP core, which removes surrounding noise, providing clear call quality. Stress-free listening and no missed calls. It also supports music and streaming media. * CVC6.0 smart noise reduction: A powerful noise reduction algorithm that combines CSR's CVC technology, combined with a special silicon mini-microphone and DSP function, incorporates a 20-channel mono equalizer and noise reduction and echo cancellation functions. Compared to general Bluetooth earphones, the sound quality of calls and the microphone is better, and the DSP's CVC6.0 technology, which has low noise and high sensitivity, uses dual microphones and digital signal processing (DSP) to reduce surrounding noise, achieving a more natural and distortion-free clear sound quality. Effective noise prevention enables stereo voice calls. * Compared to general Bluetooth earphones, the sound quality of calls and the microphone is better, and the DSP's CVC6.0 technology, which has low noise and high sensitivity, uses dual microphones and digital signal processing (DSP) to reduce surrounding noise, achieving a more natural and distortion-free clear sound quality.
