R2

My quest for the ultimate gaming IEMs was long and winding. I hope my extended and expensive journey is useful to you. My first attempt was the ARTTI R2. Everyone kept telling me to start small, something simple with a dynamic driver. Fine. I followed the advice. The R2 turned out to be a huge disappointment, especially considering that I had been using the HD660s for gaming. I know it is completely unfair to compare sub forty dollar IEMs with top tier Sennheisers, but it is what it is. The failed first attempt did not stop me. The next recommendation I decided to follow was the legendary TRUTHEAR x Crinacle ZERO:RED. Here we were finally getting somewhere. They are an excellent choice if you want extremely clean and bright treble and phenomenal vocal performance, especially female vocals. For gaming though, not so much. Their soundstage is practically nonexistent compared to the HD660s and the bass is weak. Fine. I was told I should try some planars. Planars were supposed to be the big deal. I decided to start with something more affordable, the Shozy P20. They are okay IEMs, but their sound did not impress me at all. It is muddy and nothing stands out. Overall, meh. Apparently I had to move up a level. A planar needs to be expensive. You cannot have both low price and great sound. Fine. Letshuoer S12 PRO. Another legend in the IEM world. Again, phenomenal sound, especially with a good DAC or amp, but for music. In games they failed again. Something was missing. Gaming is simply not their strength. SIMGOT. Go for SIMGOT. That is the truth and the way and the life. Fine. I gave the EW300 a chance. Another pleasant find, but after barely an hour of gaming my ears hurt unbearably. If you liked the sound but did not like the comfort, SIMGOT had just released the ultimate IEM, the Supermix 4. A killer that punches far above its price. Fine. One last chance because I was going broke with all these purchases. Fortunately this time I hit the jackpot. The motherload. A combination of fantastic sound, uniquely wide and spacious soundstage, rich bass, and most importantly brutal comfort. Eight to ten hour gaming sessions? No problem. I replaced the stock cable with a Kinera Leyding because the original one is pretty bad and this is my final recommendation. The ultimate gaming IEMs. The SIMGOT SuperMix 4.

If you're set on KZ, their pro10 (I think there's now a pro12?) should be what you aim for. Good coverage and details and all the bla bla.  If you want to enjoy good mixes (DT, Tool, Haken, Tesseract, Periphery....etc), I'd recommend something planar. I like the artti-10 and the sound they give.
