Even getting them on sale, I am not happy with the purchase at all. The fit, terrible 1/10, I’ve tried all of their inserts and none suit my ears. So they are always falling out. The requirement for the app instead of just direct connecting even for the first time is annoying and a headache. The controls, 1/10. They activate randomly if you are wearing anything over your ears. If the app provided more, if the fit was better and if the price was always the sale price it might be worth it but at the moment I’m considering just returning these.
After a few months of use because I forgot to return them in the one month time frame conclusions:
First, the fit is still uncomfortable for long periods and often slip when wearing them. I tried the different inserts and the outside fittings too. Nothing seemed to lead to a comfortable fit and I couldn't find any remedy to the issues I had. Sound quality was really strange too. I believe it has sensors to adjust sound based on the fit, and if it started to slip the sound quality or volume would suddenly change making it even more uncomfortable to use. App. The app is one of my biggest issues, the earphones would disconnect and reconnect constantly after an update, leading to it just saying that it has reconnected about six times in the frame of a minute. Really annoying and sometimes would disconnect and when I'd restart the music/podcast/video it would play though my phone instead. Really bad, I don't see the need for the app unless the earphones are providing even more functionality which if they did, I never saw or used it. I got them for the primary purpose of quality audio, decent mic and simplicity. It didn't serve any.
So after about four months, I wouldn't change my rating. Maybe for the right person these earphones would be great. But from how I see it, I wouldn't recommend it to anyone I know. Seeing how it is a product by amazon I expected more. Not to even mention that Prime Music has changed to the point I find it near unusable too.
If you are going to buy these, be ready to return them in the case they don't suit you in the first week. It isn't going to get better after the first week. If they suit you in the first week, great. But if not return them. It isn't going to get better after that.
