Specification
Brand:huawei
Blue tooth:Blue tooth 5.0
Blue tooth protocol:A2DP 1.3; Hands-free configuration (HFP) 1.6; AVRCP1.5
Frequency range:20 Hz – 20,000 Hz
Charging interface:The glasses are wirelessly charged through the case
Function:1. When real wireless binaural stereo glasses work simultaneously with the left and right mirror legs and blue tooth devices like mobile phones for voice calls/music playing, both ears can listen to the stereo at the same time to enjoy the stereo effect and provide a good use experience; 2. Low power and long battery life The blue tooth chip platform solution with low power is adopted to realize ultra-low power and long battery life. At room temperature (25℃ ambient temperature) and 60% volume, a single full charge can be used to talk for up to 2.5 hours, or listen to music for up to 2.5 hours; It can talk for 8 hours or listen to music for 8 hours. The above data are laboratory test data. Test method: after the glasses and the box are fully charged, the glasses should be charged after being turned off at low power. 3. Voice controlled glasses support the wake-up of voice assistant on Huawei mobile phone side. Users can through the voice assistant to control operation of glasses, support voice commands are: answering the phone (answer), and refuse to answer the phone (reject), play music, on one of the (a), the following piece after (a), stop playing (on TV), volume (music), a small volume (volume reduction), etc.; 4. There are two MEMS silicon wheat in the voice noise reduction glasses, which match the voice noise reduction technology, effectively reduce the surrounding noise, and bring high quality voice effect; 5. Wireless charging (glasses only) After the glasses are put into the case and fastened, the case will conduct contactless wireless charging for the glasses, which is fashionable, convenient and full of science and technology; 6. Self-discovery and fast pairing with Huawei mobile phones of EMUI9.1 or above, the phone can automatically discover glasses after opening the charging case and support fast pairing operation. At the same time, the phone can display the power information of glasses and charging case in the pop-up frame; 7. Intelligent wear detection can detect whether the glasses are in wearing state, and pause/play or rest the music according to the wearing state

Battery capacity:The glasses case has a typical value of 2200mAh
Theoretical standby time:When the blue tooth device is connected with full power, it will enter the standby state. When it is worn, it can last for 20 hours without any service
Theory charging time:Full charge time: about 2 hours
Music playing and call duration:Up to 2.5 hours of listening to music and 2.5 hours of voice calls
Call quality:1. Call indicators such as loudness of send/receive, bottom noise of send/receive, frequency response of send/receive, distortion of send/receive and echo refer to narrowband call standard TIA-810B/ broadband call standard TIA-920; 20dB Hoth noise level: > 20dB Traffic noise: > 20dB WNR: Wind noise: < 75 dB
Microphone:Two silicon wheats on the main ear to support upline noise reduction
Speaker:One moving coil unit for each side
Temperature:Operating temperature: 0℃ ~ 35 ℃; Charging temperature: 0℃ ~ 35 ℃; Storage temperature: -20℃ ~ 45 ℃
Waterproof Rate:Support dust and water resistance (IP67)

Note: This product is not professional waterproof glasses and has been tested under controlled laboratory conditions,The effect has reached the level of IP67 in IEC 60529 (overseas). Splash resistance, water resistance, dustproof function is not permanent effective, protective performance may be due to daily wear and tear. Do not charge the glasses in the wet state; Refer to the manual for cleaning and drying instructions. Damage due to immersion in liquid is not covered by the warranty. The waterproof condition of IP67 is (1) no flowing fresh water and the water depth is 1.0 meters; (2) The test time is 30 minutes; (3) The temperature difference between the water temperature and the product shall not be more than 5 degrees Celsius.
