Relatively inexpensive, but at the same time high-quality and interesting wireless headphones, which were released to the market using the Indiegogo crowdfunding platform. This is a compact in-ear model with IPX4 water protection, that is, such headphones are not afraid of light rain or sweat from active physical exercises, but less. Responsible for sound reproduction is a dual magnetic dynamic driver with a diameter of 7 mm, created by the manufacturer.

Implemented support for the AAC codec, which can be called the most common among modern smartphones. Connecting to a signal source is a Bluetooth v 5.0 interface with a range of up to 10 m. But in terms of battery life, everything is very ordinary and boring. So, on their own, the headphones pull out up to 3.5 hours of continuous play, which is by no means a lot by modern standards. The complete case also does not shine with its capabilities - it allows you to extend the battery life by another 14 hours. Despite the fact that the headphones look a bit bulky in the photo, they actually weigh only 5 g. USB-C interface located on the bottom of the case.
