EPZ - Q1 Pro

If it's available, maybe the EPZ Q1 Pro. It's quite small and doesn't have huge nozzles, but it's a more ergonomic shape than the Chu 2. If you also have small conchas (the "bowl" inside the ear, just outside the ear canal) then some find the Chu 2 uncomfortable because of its shape, even though it's quite small. Otherwise the Wan'er is fairly safe. The OG has a crappy cable but most find it fits slightly better than the Wan'er 2, and IMO it's tuned better as well. The QKZ T1 is a good cable that fits the OG. Don't know about the Fiio but they have a reputation for all of the their IEMs sounding pretty crap, except the FH3 and the new flagship one. So I'd probably skip that one.

I can suggest the Tinhifi C3 mk2, really comfy semicustom shell. Or the og Celest Wyvern black, semicustom as well, and can be had for cheapo nowadays! If not, the EPZ Q1 Pro or the EPZ G20 (same shell as the Q1 Pro, but gaming oriented, also comes with a 2m usb cable that supports a boom mic, and its inbuilt dac can be PEQ'd with the Walkplay app). To me personally the shape of the CCA Rhapsody and KZ Am16 is super comfy, but i kinda have bigger ears!

EPZ Q1 Pro. My planars didn't get any love anymore after I have that iem

EPZ Q1 Pro - Perfect comfort - Great looks - Great cable - Perfect sound after EQ - 30 bucks

If I had only these 3 options then I'd 100 percent go for Zero Red, but my recommendation is EPZ Q1 Pro

EPZ Q1 Pro, InAwaken Dawn MS, Simgot EW200, Singolo...Don't want a planar because these things don't have enough amplification to drive them.

If you have an epz q1 pro, try copying juzear clear's bass shelf. Same driver config. Also, for non-bassheads, do yourself a favor and ask Ducbloke for his epz q1 pro PEQ, turns it from a sub $50 to $150+ easily.
