Linsoul 7hz Salnotes Zero IEM $24.83 + Delivery ($0 with Prime/ $59 Spend) @ Linsoul Audio-AU via Amazon AU

This price in red, without mic. Other colours a couple of dollars more.
I have been really happy with these for gaming and music for the past couple of years. Good tangle-free cable, clear sound, does a decent job of blocking external noise, can wear for several hours comfortably… and less than $25 🤷🏼‍♂️
