In the following sections, we have all the keys to this tiny accessory.

Presentation, design and construction of the Haylou GT2S headphones

The GT2S, from Haylou, as we say, are a very small device designed to reproduce audiobut also capable of transmitting our voice, with a wireless connection. Apart from their compact size, these Bluetooth headphones are distinguished by providing high autonomy.

Product packaging

The Haylou GT2S arrive in a small and simple box color white. The front shows a great image of the product and little else. You see the manufacturer’s logo, the device reference and a brief description of its role.

A simple box with information in Chinese and English

The information provided by the device manufacturer is quite meager. The rear part has a double column, one in Chinese and one in English, the minimum specifications that can be useful to the buyer. Understand, the connectivity of the accessory and the capacities of the batteries that power them.

Brief product information

The box arrives sealed with a clear adhesive seal. Inside the first thing we have on hand is the case with the headphones inside. A cardboard divider compartments the rest of the box space, which is almost all air.
