The cons are ultimately nitpicks given the very low price, no one is going to expect a $20 IEM to have good technical performance Easy buy for anyone, I personally use mine fairly often despite having much more expensive gear on hand.

The Mele is a well tuned bassy IEM with some noticeable shortcomings like piss poor treble extension and poor technical performance. (Very blunted notes, poor separation and merely average imaging.) I usually don't complain about technical performance in this price point, but Tripowin promised technical improvements over the BLON BL-03 (Which is the IEM that inspired the Mele's creation.) I'm sadly not seeing any technical improvements over the BL-03, the Mele's technical performance is about on par with the BL-03 which is disappointing, especially...

This set somehow received hype when it came out a few years ago (I'm guessing Zeos hype.) FA7 is almost complete garbage IMHO, the only thing missing here was a random upper mids / treble spike which would round out the awfulness of the FA7. I dread to think how the infamous Shozy Ceres and Effect Audio King Arthur sound like, both graph like a worse FA7.
