Don't like the shell but I'd be interested to hear (pun intended) about how they sound!
I think this Cat Ear brand is relatively new, haven't seen them churn out earbuds before. I'll probably be buying this earbud at the next sale if the discount is good enough (and must hide it from the wife when it comes!)
The Cat Ear brand did release an IEM recently called the Cat Ear Mia: https://hifigo.com/products/catear-mia
One of the rare reviews here: https://www.audioreviews.org/cat-ear-mia-review-kmm/
Seems to be a V shaped IEM and from reviews, looks meh (haven't heard it though, but gave it a miss after reading reviews). Interestingly, for this Cat Ear Mia IEM, they were mewing (no pun intended) about using -196℃ cryogenic treatment for the cable, connectors and driver units. Smells gimmickish. While diehard audiophiles are doing "burn in" for their gear, this company is doing "freeze in" LOL.
