Terrible, they discharge in 30 minutes while it claims to last 4 to 5 hours. They don't fit well in the ears and disconnect all the time. Guys, they're not worth it, I should have spent an extra 3 euros to get the Xiaomi ones.

Terrible. What the kids say about the latency is true. They disconnect on their own for no reason, but in order to connect, you need to simultaneously close, open, and double tap on one to connect to the other. Nowhere does it say this in the manual. The sound is mediocre to bad. During calls, you can barely hear me. A wrong purchase, luckily they came out cheaper from abroad.

Simply unacceptable to have them for sale, in videos on YouTube, mp3, phone or games there is a 1-second delay, the sound never reaches the headphones. Does no one in the company know to inform the world what is happening before buying? If there is any adjustment in the driver and the problem is solved, someone please help, otherwise for me at least they are completely useless and it is a shame for such products to be released on the market without consequences

Mediocre sound quality in music. Does not connect in stereo. Only one at a time. The lid broke with the first opening. Finally, the volume in phone calls is unacceptable. Neither you can hear nor the person you are talking to. Money wasted.
