My favorite part of this product is the app. The app allows you to play music/answer calls by pulling apart the earbuds, and pause music/ignore calls by putting them together by their magnetic ends. When paired with a Samsung Galaxy phone such as the Note 8 (which is what I'm using with it), Note 5, S7/S7 edge, and S6/S6 Edge, you can use audio effects, as shown in the third picture. For me, the audio effects make music sound better and more enjoyable. The only thing thats annoying about it is that when the UHQ Audio feature is enabled, most of the time it makes the audio sizzle and pop. But other than that, these are amazing headphones, especially considering the super low price.
