Neucan performance is further improved! Complete wireless earphone "HUAWEI FreeBuds 4" suitable for the new generation

"HUAWEI FreeBuds 4" is equipped with a hybrid active noise canceling that combines a feed forward microphone and a feedback microphone, enabling noise canceling of up to 25 dB. The in-house developed "adaptive ear matching technology" automatically detects the shape and wearing condition of the user's ears and selects the optimum noise canceling to effectively reduce low-frequency sounds. The main body is equipped with an LCP diaphragm and a highly sensitive 14.3mm dynamic driver, which supports a frequency of 40kHz and enhances the reproduction performance of the high frequency band. In addition, it is equipped with a power engine that enhances bass and produces deep bass by enhancing the vibration of the diaphragm. In addition, since it supports dual device simultaneous connection (multipoint), two devices can be connected at the same time. The main body can be worn more comfortably by analyzing data from over 10,000 ears and simulating external pressure, and because it is lightweight, it does not get tired even when worn for a long time. You can also double-tap the main unit to answer / end the phone, play / pause music, and press and hold to turn noise canceling on / off, and swipe to adjust the volume. Supported codecs are SBC and AAC. Battery life is about 4 hours for the main unit alone and about 22 hours when combined with the included charging case. Only one side weighs about 4.1g.
