Hello averyone. I'm using Jabra for years. They're best for me and many of my friends.
Why? First , they are very,, safe to use , which for me is important . Resistance against water and dust is the best . The sound is great. Important is to install app from play store ,or apple store . Is called sound+ Jabra. There, you can customize the : anc, fitting , set the equalizer

Finally, after 2 months of use, I concluded: TRAGIC headphones. My callers stopped hearing me well and the connection with my phone was frequently interrupted. However, this only happened during phone calls. When I listen to music or watch videos, everything is fine. So, they are good for mp3 players, not for mobile phones!!!
Another tragedy is the active noise cancelling. The ANC is limited to announcing "ANC" in your ear. And then, not silence, but noise, because the ANC doesn't work! However, it's fantastic if you go for a run at night, because even with the ANC, you have full situational awareness. It's not a bug, it's a feature, right?

I bought different headphones and found peace. If you value your money, don't get them!

Durable device, good fit in the ear, with a long-lasting battery and speaker.

The major drawback is its microphone (at least in mine), as there are several times when the callers complain about very low voice volume. The problem was not resolved even with the manufacturer's instructions and actions.

The purchase cost in relation to what the device ultimately offers and for the Jabra brand is not justified at all.
