Advanced Features
apt-X & apt-X HD High Quality Sound
The Glazata EC300 utilizes a high-quality smart chip by Qualcomm, supporting AAC and apt-X codecs. This technology significantly reduces audio delay compared to traditional SBC codecs, providing superior sound quality for music and calls. Your mobile phone must support APTX for this feature.

Dual Microphones with ENC Noise Cancellation
Equipped with dual MEMS high-sensitivity microphones and ENC (Environmental Noise Cancellation) technology, the EC300 effectively blocks out ambient noise and wind interference. This ensures crystal-clear call quality, making conversations sound as if you are face-to-face, even in noisy environments.
