Quick summary of what's below, fun V-shaped iems with highs being extremely present, not for everyone. For the price these aren't a bad buy imo.
These iems are very V-shaped and would classify these as fun iems . The highs are very present and can be fatiguing, to the point that I've had to make new custom eq setting on my devices to tone down the highs. Some might say these don't have bass, these do have bass but won't satisfy someone who likes bass. Being iems the sound stage isn't big and is intimate, but I like the separation and clarity these have once some adjustments are made. I've found the vocals are never drowned out so I like this aspect of these iems.
The provided eartips are OK for listening sessions under an hour, they provide a good seal for me and don't fall out, but they do start to become uncomfortable and hurt a little near the hour mark so have changed them to comply eartips. You also have to make these sit perfectly in your ear, the housing can push against your ear and start to get painful after a while.
The cable is rubbery and holds memory which is a bummer, but again isn't bad for an iem at this price range. The fact they are detachable allows for an upgrade in the future.
For what you pay I'd say you get pretty nice iems once some equilizing is done, and becomes better with some small upgrades. For me points lost for comfort and I'm not too picky on sound, but there's room for improvement here too.
