Monaural/Binaural Mode
Each headphone Bluetooth can be used individually, so you can flexibly make calls and listen to music, and also share with friends at any time. Or use both headphones for powerful stereo sound. (Note: 1.Mono mode is not transparent mode. 2.The headset cannot be connected to two devices at the same time.)
Comfortable, stable to wear
It took 3 years to build a professional ear database. A single wireless headphone is as light as 8g, and you won’t feel pressure when you wear it for a long time. There are 3 different sizes of earmuffs (S/M/L). The style is suitable for you, and the hanging ear is comfortable and does not fall off. They're great for running, jogging, fitness, hiking, and more.
Note: Use suitable ear caps to improve the sound quality.
Warm Reminder
1. Do different ear caps affect the sound quality?
Be sure to replace the ear cups with the appropriate size (S/M/L). It is recommended to use earmuffs of different sizes, listen to the same song, adjust the volume to more than 50%, and find the earmuffs that suit you to get the best sound quality.
2. Are the ear buds uncomfortable?
Each ear is a different size. (1) Adjust the wearing angle of the ear buds. (2) Adjust the depth of the earphone inserted into the ear canal to reduce the pressure on the ear canal. (3) Take off the ear buds every 60 minutes and relax your ears.
3. Why did my earphones disconnect?
(1) The optimal distance for Bluetooth connection is 15 meters or less (2) Environmental interference or strong magnetic fields will affect the transmission of Bluetooth signals. (3) Please check whether the mobile phone network is normal, whether the network speed is slow, and whether the music is loaded.
4. Factors affecting playback time:
Song type and playback volume. The recommended playback volume is 30% - 60%.
5. If you have any problems with your earbuds, we will provide you with a solution.
