perhaps the only one on the market with a real noise-canceling filter, but unacceptable battery life.

Unfortunately it started well, but after a couple of weeks, it started cutting out during calls, while I can hear very well.

Very good sound and it helps me a lot since I don't need to have it in my ear all the time. Also, the clip to attach it to clothes is quite strong and doesn't move.

I had the R1 and it was VERY GOOD and that's why I preferred it, but it has nothing to do with the R1. In 3 months, the headset's reset broke, so I took it for service and I'm waiting for an update from the service. They replaced it with a new one

Completely useless, does not connect to 2 phones as promised. The r1 was excellent and that's why I preferred it, but it has nothing to do with the r1. Also, it didn't even have a cord for the neck in the packaging! They cheaped out. The button placement is not ergonomic like the previous one. Also, the noise canceling it promises, my conversation partners haven't told me that they can hear me better than before. Failed purchase!

It is very good in terms of sound quality. The battery is good and lasts for one and a half days with continuous talking from morning till night. The only downside for someone who works remotely from the phone is that the vibration is not felt at all compared to other well-known Chinese brands but the quality is better.
