Unfortunately, I can't say anything about semi-open.
They are definitely suitable for sports. They fit surprisingly well. They don't feel like it. I don't know if it's the weight, but I hardly notice them in my ears.

Hello
I am very disappointed with the product. The sound is way below that of the AirPods Pro 2 and the noise cancelling is pretty bad. It sits well in the ears but the sound is not balanced and there is a big lack of bass.

hello

i am very satisfied - are very comfortable to wear and great for phone calls or video calls.

I've had them for 2 days and am very happy with the significantly better bass/sound. I also find the ANC much better than my old 75t and even better than my Sony WF-1000XM4!
With loud music in the pub, I was able to enjoy my music surprisingly well and I was really impressed. A Dolby Atmos video via YouTube blew me away!
With ANC, however, it really depends on how well they fit your ears, which are slightly different for everyone... Unfortunately, the only thing that helps is to try them out on friends...
For me, wearing comfort is also important and they are hardly noticeable. I haven't tried sports yet and it also depends on your ear fit...

I've just bought them. I find the noise cancelling very disappointing. You can hear surrounding noises. They just seem to be slightly attenuated. I've just bought the jabra elite 85T, which I don't have at hand to compare, but I have the impression that I hear a lot more outside noise. I'm going to test them a bit more, but I'm very reluctant to give them back. This is a personal opinion, of course.

I have been using the Jabra Elite 10 since Saturday. I'm pretty thrilled so far. I've never had anything so comfortable in my ears. Even after several hours they fit like a glove and I almost forget that I have something in my ear. I think they are good for sports. Because of the low weight they hold really well. At least for me. They also have IP57 protection, which is the best dust/water protection on the market.

I am also very satisfied with the sound. Ok, I'm coming from Samsung Buds that are over 3 years old, so I can only make a limited comparison. I have only used my wife's AirPods Pro 1 a few times. I see the Jabra in front.

All in all, wearing comfort and operation were the most important things for me. That's where they really come up trumps in my eyes. They are easy to use even with gloves on. What good is the best sound if they are uncomfortable or even painful after 20 minutes?

I have not noticed any environmental noises so far. In contrast to other plug-ins, they sit very ideally and firmly with me, which amazed me.
Very good material, workmanship and sound. Just Jabra
