The G3 wireless headphones with an open design transmit sound through air conduction, with the speakers positioned just in front of the ear canal, leaving your ears free. This allows you to remain aware of your surroundings, including traffic and voices, while running, cycling, or walking through the city. They pair with your phone or tablet via Bluetooth 5.3 and maintain a connection up to 10 m away. The hooks hang behind your ears and the flexible rear strap goes around the back of your head, ensuring the headphones stay in place during movement. On the side, there is an LED display that shows the current battery status.
Inside is a built-in 300 mAh battery, which according to the seller lasts for up to 30 hours of music playback or 30 hours of calls, and up to 100 hours in standby mode. They charge via a USB-C connector. The headphones also have a slot for a microSD (TF) memory card, allowing you to play music directly from the card without a phone, for example during training when you leave your phone in the locker or at home. They are controlled with three buttons on the side, which allow you to increase or decrease the volume, skip tracks, and pause playback. A long press of about 1.5 seconds activates the voice assistant on your phone, and holding both volume buttons switches the language of the voice prompts between English and Chinese.

The rear strap is made from a memory titanium alloy, which can be bent up to 360 degrees according to the seller. Since nothing is inserted into the ear canal, you can wear them with glasses or under a cycling helmet. After training, simply wipe them with a dry soft cloth and store them in a way that prevents the strap from being unnecessarily crushed under heavier items.
The G3 headphones are a practical choice for anyone who wants to listen to music while exercising and still be aware of their surroundings. The open design with air conduction keeps your ears free, and the battery life of up to 30 hours of playback covers several training sessions without needing to recharge. You can play music from your phone via Bluetooth or directly from the microSD card slot. The LED display will show you at any time how much energy is left. They are suitable for running, cycling, gym workouts, and everyday commuting around the city.
