You can use them anytime, anywhere without worrying about the battery level. In addition, they support mainstream Type-C fast charging, and with just 10 minutes of charging, you can use them for up to 2 hours! 【HiFi Stereo High-Quality Sound & Clear Calls】By adopting a specially designed 10mm large-diameter ultra-wideband dynamic driver unit, these earphones achieve realistic, immersive high-quality sound. Equipped with a 10 mm diaphragm, they deliver beautiful high frequencies, luxurious mid-range frequencies, and powerful bass, just like a concert. You can enjoy high-quality sound with not only powerful bass but also excellent balance in each frequency band. They can produce immersive 3D stereo sound and clear vocals. Furthermore, they employ CVC noise reduction, a higher-level ENC noise reduction technology. The built-in microphone analyzes the sound range separately from distant and close distances, processing the audio signal. 【Single-Ear, Dual-Ear Use & Multi-Functionality】You can use both left and right earphones simultaneously, or you can use only one earphone. After pairing, you can use the earphones by simply taking them out of the case, which is very convenient. In addition, you can perform necessary operations such as volume adjustment/music playback/pause, call/end/reject/next song/previous song. Furthermore, you can call the voice assistant Siri for voice control, achieving a smart design.
