In one month, the left earbud stopped working, probably due to sweat from wearing them while running. It malfunctions, doesn't connect to the right one, adjusts the volume on its own, and now the case battery is also draining. It's garbage

I don't remember in my life ever leaving a negative comment. But these headphones are perhaps one of the worst things I have ever bought.

Firstly, they do not have a soft lining on the inside. Their fit was extremely painful for the first two weeks.

Secondly, compared to previous headphones of the same price range, these have the worst sound isolation. I can hear everything around me and struggle to hear what is playing through the headphones.

Lastly, they developed a problem after 1 month of regular use, resulting in the need for replacement (specifically, the left earphone produces static noise and its battery drains in 10 minutes).

STAY AWAY, GUYS, DON'T EVEN THINK ABOUT IT

I use them for running. They connect easily and quickly, they don't disconnect even after several hours. They barely disconnect immediately when they are placed in the case.
Every time I have had to speak, I hear and sound good, unless there is wind as they do not isolate at all.
They don't fit well in my ear, but nevertheless they are not bothersome, the "hook" is made of silicone and it doesn't become annoying even after hours.
Satisfactory battery, I had no issues up to four hours.
