Nice strong and sounding pair of iem (i have moondrop Aria, Tinhifi P1 plus, kz zax and not bad at all any of them) and i considered the Mele as a kindish "of Aria and all i know that i use more the Mele than the Aria probably for the bass, even though Aria have no bad issue with low frequency, I find Mele nice to hear and even fall asleep when i don't use the small and comfy, great Tin P1. Mele and Tin P1, i find, are the 2 "contrast" iem as their timbre and the kind music played in. each of them is completely the opposite sort of listening IEMS.
50€£$.. of course, without hesitation are a bargain and i will recommend either to keep as a 'collection' for bassy audio or even very good to wear with their excellent fit for long listening too as themids highs aren't fatiguing at all so you can enjoy for hours. And especially good are if you like subs bass guitars hip hop and electronic, Minimal trance style even though female voices are pretty smooth too to listen, indeed. Then, let's say it they are gorgeous looking with a nice tripowin silver 16 cores cable,(i use Zonie) as little jewel decoration without breaking the bank. I can't recommend enough, really...
