A pair of true wireless earbuds with Bluetooth 5.3 connectivity, active noise cancellation (ANC) technology, and a charging case. These earbuds may also be marketed as suitable for gaming.
Active noise cancellation (ANC) technology is designed to reduce unwanted background noise by generating an opposing sound wave that cancels out the noise. This can help to improve the clarity of audio and reduce distractions.
The charging case is a compact case that stores the earbuds and charges them when they are not in use. This can help to extend the battery life of the earbuds and ensure that they are always ready to use.
