Decided to give these a try. Was looking for a pair of in-ears that sit flush with the ear, well more flush than the Sony WF-1000x, and were in ears (IE, not AirPods). Wanted something that would fit underneath a hat for the Chicago winter that is looming. Shoveling snow does better with music as well. I trued the NuForce BE8 Free which weren't that great. The sound signature was a little boomy and controls unintuitive. The lack of sweat resistance wasn't great either. These seemed to be a much better solution.
I personally enjoy the brighter sound (more linear), though I wish these had a little more sub-bass without needing me to use their sound stage adjustment. That said, I make the sound stage bigger (pinch open on the EQ screen) and add a bit of warmth and I get a signature similar to what I prefer.
I have some drop outs, they are shorter than what the WF-1000x gets, and when it occurs both drop (instead of one). So this issue is between the source to master 'bud. Nothing too crazy, we'll see how they do when I go into more open spaces.
The major issue I have... While the AirPods can register a double tap accurately and consistently for me, these can't for the life of them. Too slow and I pause my music. Too fast and I pause my music. It's quite annoying.

Oh, I saw a lot of talk about tips earlier and did want to chime in. I'm using the stock silicone tips right now, medium size (I typically use smalls, but mediums sealed better in this case). I do get quite a bit of flex though, but I do with just about everything...
I did see someone saying that Comply foam tips muted treble, this isn't the case if you insert them using a different method. Tyll (from InnerFidelity) has a tutorial of this on YouTube, in short you press the nose of the tip towards the plastic sheath before rolling. This will help out with the treble issues. Though the wax filter is still there on the Comply, that could interfere with sound as well. Solution to this is to get Comply tips that don't have the filter?
