Bad sound quality and low volume from the headset, barely tolerable for phone use, not suitable for music at all. The microphone is terrible, the person you're talking to can't hear you unless you speak loudly. Battery life is satisfactory for its size, but there is no low battery warning and the Bluetooth disconnects abruptly. Miles behind the basic Sony and Plantronics ones I had tried in the past. Don't be fooled by the brand, it's just a cheap Chinese Bluetooth that is not worth its money, buying it for over €15 is a rip-off.

I would expect more from such a brand. The speaker's volume is loud, but of poor quality. In a noisy environment, you may not understand the other person. Another major drawback of this Bluetooth is its inability to play multimedia, something that cheaper Bluetooth devices on the market can do. If someone wants to use it for music, YouTube, etc., they will have to install an application on their smartphone to indirectly enable it, but the sound quality is such that you can't understand what you're hearing (monophonic sound)! The talk time is excellent (you forget to charge it), but now it is the minimum that interests me. I do not recommend it.

To summarize the positives and negatives:

+ Small size, lightweight, easy to fit in the ear, long charging cable, long battery life.
- Poor sound quality, inability to play multimedia.
