Some of this review does bleed over into the headphones themselves, but they do go hand-in-hand. The app is not great and has not been updated for over two years. In all that time they still haven’t release version 1.The EQ options are limited to a couple of pre-defined bass settings. The on-head detection is completely unreliable. The charge percentage drops from 100 to 85 within about a minute of use. Even a perfect app would not compensate for the uncomfortable fit of the headphones with glasses (particularly compared to Sony’s WH-1000MX), but perhaps they need to break in.

Limited customization through the app. The equalizer is 3 settings and three settings for ANC. When you pay this much for quality headphones at least give me an app that has some investment. ML can do better

For as much as these headphones cost, you would think that the app would be worthy of these great sounding headphones. App needs to support all music devices. And app needs to update users when firmware is available.

I love the headphones but I continually have connectivity issues to my I phone. The app can’t find the headphones it’s very frustrating.
