This is a decent set of iems especially if you like bass. I got my set for around $50 used and would say that's a great price for these. I wouldn't consider these for $145 as the competition in that price range has increased immensely since their release (when most reviews of these are from).
The treble is natural and slightly forward, presenting everything energetically. The mids are natural sounding, but often overshadowed by the bass. The bass is impactful and huge. The focus of these iems is absolutely the bass; That is made obvious by the bass bleed into the lower mids and the sheer volume of it. The bass is oftentimes tight, very rarely coming across as boomy or unrefined. Too much bass can always be remedied with an EQ, but the out-of-the-box experience is overly bass-heavy in my opinion.
These are a moderately detailed set of iems until you EQ them. With the bass reduced many details become present that are usually covered by the overwhelming bass. The soundstage of these iems is narrow which facilitates a very focused listening experience, having everything placed into a very clear center image. Imaging is average for a modern $50 pair of iems, but outclassed by most modern $100+ sets that I have heard.
Overall these are a fine set of iems, but the amount of bass holds them back in my opinion. I would recommend buying these on sale or used if you're interested in testing just how bassy they are.
