4.7/5.0 Stars for me & fantastic IEMs for the price! One of my favorite IEMs I've owned. Highly recommend if you like its kind of W-shaped sound signature/profile. Mids are more present than graphs would suggest. Lower mids are still a little scooped out though. So many pros to this $69 IEM...

Only cons for me really are its stock cable which I recommend changing out, accessories like the stock eartips the case is fine, and the upper mids are just a little too shouty/accentuated... otherwise ????

Here's a graph/some measurements from cqtek's review ????

And some more thoughts:
