【Air Conduction Technology That Doesn't Block Your Ears & ENC Noise Canceling for Calls】 Earaku earphones use air conduction technology that allows you to hear surrounding sounds naturally without blocking your ears. This provides both peace of mind and comfort, while also increasing freedom during calls. The ENC noise reduction function suppresses ambient noise, delivering clear voices. The call headset is ideal for various situations such as telework, online classes, warehouse work, and driving, as it reduces keyboard sounds and air conditioning noise during meetings. 【Excellent Fit & Ultra-Lightweight 32g & 270° Adjustable Mic Boom】 Earaku open-ear earphones are lightweight at only 32g, ensuring comfort even during extended wear. The use of high-quality, soft silicone material ensures a perfect fit without discomfort, even after long hours of use. The microphone boom is 9cm long and can rotate 270°, allowing you to position it near your mouth during calls or behind your ear when listening to music, making it adaptable to different uses. 【Latest Bluetooth 5.3+EDR Technology & IPX5 Waterproof】 The open-ear Bluetooth headset is equipped with the latest Bluetooth 5.3+EDR technology, enabling free movement within a communication range of up to 10 meters. It improves issues common with previous Bluetooth headsets, such as unstable communication, power disconnection, fast battery drain, and audio interruptions.

You can comfortably enjoy high-quality calls without worrying about splashes or minor spills. 【10 Hours of Continuous Playback & Wide Range of Scenarios】 Built-in high-performance lithium battery allows for up to 10 hours of continuous use with a 2-hour charge.
