• 4 Microphones & ENC Call Noise Cancellation: Each Bluetooth earphone is equipped with 2 noise cancelling microphones with ENC technology to suppress ambient noise for excellent voice enhancement and cancel background noise so your voice can be heard clearly on the other end of the call.
• Bluetooth 5.3 technology and automatic pairing: Bluetooth 5.3 technology offers lower latency and better anti-interference performance (latency much lower than 65ms). This allows you to enjoy a continuous and stable connection even in areas with difficult signals (places with a lot of people, such as subways and buses). When you open the charging case, the headphones will automatically pair with each other (Hall switch) and connect to the last connected device.
• 25 Hours of Continuous Music & Fast USB-C Charging: The 13mm speaker of the wireless earbuds delivers a powerful and wide sound range that makes the highs full of dynamics and the bass powerful. Provide up to 5 hours of high-quality sound on a single charge, and the included charging case allows for four more charges. The case can be fully charged in just 1 hour via the USB-C charging port.
• Sensitive Touch Control & Dual Mode: Great in-ear headphones are not limited to one main earphone, you no longer need to wear a fixed earphone for single ear mode. Each wireless sports earphone can be used individually or in mono mode. Smart touch controls make everything easy and allow you to control music, calls, mute and voice assistant.
• Lightweight Design & IPX7 Waterproof: The surface and in-ear angle of the wireless earbuds have been polished and refined multiple times to achieve a balance between beauty and comfort. The single-sided earbuds weigh only 4g, so you won't feel tired even if you wear these wireless Bluetooth headphones for a long time.
