Just picked up these earbuds today. I was extremely excited to try out these new headphones and the personalized setup feature. Unfortunately the headphones always disconnect before the test is complete, and it’s always at the same step. I made sure the headphones had full battery, were connected and worked before starting the test and made sure I was in a silent room. The headphones always disconnect when the test try’s to play music to see how my ears are. It just announces that it will now play music then the screen goes blank. After sitting for around 30 seconds I get a notification stating “Error, Lost Bluetooth connection to device.” All of the other functions of the app work fine with no issue at all. But one of the main selling points for these earbuds is having issues. Hopefully this issue will be resolved so I don’t feel like I waisted a decent chunk of change on earbuds.

I don’t understand why people are worried they have to make a account to use the app, like bro it’s not a big deal if it is just make a dummy account because without the app you can’t enjoy these amazing earbuds. As far as sound they crush any buds I have tried and I have almost all of them. Now for comfort they are not bad but compared to my Bose silent buds it’s not even close. But they stay in my ears and that’s a huge plus. Can’t say the same for apple pro buds that i really enjoy but they don’t stay in my ears at least. But if you want mids highs super bass then you can’t go wrong. These and the Bose. The only thing that’s lame is you can’t change the volume unless you press and hold or something weird. That’s gotta be fixed if I’m paying over $350

Many years of experience with a variety of high performance audio gear and headphones. I am satisfied with the overall sound quality but also agree on on the weakness of app as pointed out in other reviews. However there is one other thing that I suspect is because of a mismatch in what the iPhone software thinks the headphone volume is versus actual sound being produced. I am getting constant IOS reminders that the headphones levels are too loud for safe listening. In reality the volume is set to maximum just to be able to get a moderately loud enough listening level.

I’ve only been using the app for a few days, but the only qualm I have is the whole needing both earbuds on to access the app. I can only wear one earbud a time at work and if I need to check something real quick needing to go and grab my other earbud is super annoying.
