At that price, I think they're definitely worth checking out.
My experience has been mostly positive, with the negatives really just being minor hiccups and seemingly random occurrences. These things include the earpods not automatically syncing up when I remove them from the case. 9/10 times they connect when I open and remove them from the case, ready to go, but occasionally they do not and I have to manually power them up. If I power them down and don't return them to the case, when I go to turn them back on occasionally the left earpod does not sync up. I have to return them to the case, which powers them down, and then take them back out. This actually seems to happen fairly often in this scenario, so I am inclined to think this is a bug of some sort and possibly fixed with an update. I usually have the case on me, anyways, so this isn't a real issue for me. I would be curious to hear from others if they have noticed this behavior, but it has happened across two different pairs.
Outside of these little things, when I go to use them they are solid. They sound good and I am actually pretty impressed by the sound quality for a Bluetooth option. The connection holds, range is good, and I have not experienced any stuttering or dropouts using them. They hold a charge of roughly 3 hours - which I find adequate - and the case is supposed to hold an additional 6 hours which seems accurate from my time. Having an adequate seal and inline controls were a must for me, so this is definitely a positive. They fit snug, if not mildly uncomfortable at first, and there are no worries about them falling out when running. The microphone quality was described as alright, but I was in a pretty quiet envrionment when I tested them.
I've only used the Jabra Sports Life app a few times, so I can't really comment on it too much. You can utilize a few other apps, like Strava, and make use of the heart rate monitor through that. While the app is a pretty simple affair, it seems like it'd be pretty useful for the cardio driven individual. Another user on here mentioned that the heart rate monitor seemed to be really off for them, but mine seems more accurate than not. If you require as accurate a reading as possible, a chest strap hrm is still your best bet.
Overall, I am really happy with them and feel them a worthy alternative to the Airpods if you are interested in other options. Best Buy is good about returns, anyways, so worth checking out.
