They sound good. The highs aren’t sharp like on some kz zst. If you can get a good seal, the sound become on par of overhead headphones. Bass is punchy and doesnt bloat to mids. Mids sometimes sound hallow. Best music genre is pop, edm. On rock and classical they lack the mids but enough for casual listener. Tips that you get as gift are large size 13mm diameter.
I use these as in ear monitors. I've also compared them to high end headphones (Sennheiser HD800s). In this comparison they felt somewhat mid-scooped. Low mids are not apparent, but for most popular styles of music that might just work out fine. As IEM, as a guitar player, they are perfect. And for the price, you can buy a spare too.
