SE535 (Pro)

I've owned all 4 levels of quality of the Shure IEMs (2xx, 4xx, 5xx and now 8xx). Each step up is a pretty huge jump in quality, especially between the 2s (which I consider pretty shitty tbh and not worth the price) to the 4s. Now that my ears are used to the quality of the 846s, I can't go back. It's like going from 4k back to 720p, or OLED back to IPS

My first (for me) very expensive IEM's were Shure SE535's. I was amazed by the details I never heard before in songs i've listened to for years.

Shure SE846. They aren't perfect but pretty good even though more on the pricy side. They have a fairly neutral sound and clear even when a lot of sounds are played at once. I had the Shure SE535 before. They are not as good and need a little bit of equalizer tweaking but have a better worth to price ratio. SE846 are heavier than the SE535 and your ears may need a bit longer to adjust to them. Since you don't seem to listen to a lot of technical music the SE846 are probably overkill but the SE535 may hit the mark.

I have the Shure SE535 myself, which I like, but they're relatively flat, tuning wise. Most manufacturers try to follow stuff like Harman or IEF tuning.

The KZ in ears are great for the price! Lots of low end I’ve owned them, shure se215, se535. The bang for buck can’t be beat for the KZ ZS10 pro2. The cable design is superior to the shure design IMO

The shure cable rotates 360\* which works great at first. But when it gets filled with sweat after a year or so it will corrode the connection. Then your always getting dropouts in one ear The KZ are 2 pins that don’t move, and sweat can’t get inside to corrode
