In 2 months, it will be 2 years since I bought them.
Multi pairing:
No, even though they claim it supports it.
Speech:
Terrible, they don't hear you if you speak normally, you have to shout a little and even then you can only hear them "deep" and softly.
Sound:
For the first 6 months, the sound was good for my taste, but then it noticeably declined. They maintained this sound quality until now.
Battery:
The battery never lasted the 6 hours that it claims, even from the first use after purchase. It lasted 4 hours + 8 with two charges from the case, totaling 12 hours for the first semester. In the second semester, the battery life started to decrease, and after a year (going into the second year) from December that just passed, meaning for the past 5 months, they barely last 2 hours. For some reason, the left one drains faster and only lasts for 30 minutes.
Connectivity:
Quite strange, I would say. Sometimes when I open them, it prompts me to pair again. Sometimes they connect, sometimes I have to put them in and take them out of the case again, and sometimes they connect normally. In the last 2 months, the left one stopped connecting. When I put it in to charge, it showed a dash indicating that it is closed, instead of showing the lightning bolt... As a result, I would take both out and notice that music was playing from one of them. I would put them back in the case, take them out again, and they would work. Then it started needing a little twist left and right to work. Then it took hours... then the whole night, and magically fixed itself in the morning.
In the photos I uploaded, I show exactly what I am explaining.
Conclusion, if you want them for a maximum of 6 months, maybe a year, go for it. If you want them to last longer, they don't do the job. With the 50€ that I bought them for, there are much better options available
