My favorites for PUBG so far: \- Kefine Delci Angel Ears (Delci AE) 70€ \- Tripowin Vivace 30€ \- Truthear Crinacle Zero blue 60€ \- Simgot EM6L 100€ \- QKZ x HBB 20€ (but short-lasting) What I wouldn't recommend: \- 7Hz Salnotes Zero (partrially usable) 25€ \- Moondrop Chu 20€ \- KZ Zex Pro (CRN) 30-50€ I do have the HD 560S, and I use them balanced using the 4.4mm cable and the Akliam PD4. They, like most headphones, cause "gamer hair", and that's a look I can't rock at work. That's why I mostly use IEMs. I also use the IEM-s with 4.4mm cables.

They are worth it, complete package bass adapter+useful carry bag+foam tips. I got the Zero Blue 2. On my phone, the blue 2 sounds warm and bassy but on snowsky it sounds brighter with less sub bass but that the beauty you can either use the 5 ohm adapter for more bass or use the built in equilizer. I'm listening mostly rock music but I do listen to some pop like Taylor Swift which I think blue 2 shines.

I got the blue 2 because of the smaller nozzle. I have small ear canal and use S size tips on my iem. Mostly critical listeners' trashes the Zeros but for me it sounds better than what they said. Just check the reviewers who praises the Zeros and decide.

The 7hz G1 is marketed or gets pitched often as a "gaming iem with punchy bass," it actually had no bass at all, despite EQing it everything was still very air-y and analytical. Preferential sound profile is similar to the Zero 2 Blue or Dunu X Titan.[](https://www.amazon.com/HIFIXAUDIO-7HZ-G1-Silver-Plated-Audiophiles/dp/B0DRFB71TP/ref=sr_1_2?crid=145OWH892YHPY&dib=eyJ2IjoiMSJ9.0A5YdW-YIkpHtuA6tSowAAEXq-FyiDdBWCq2ml7Kq57nu51qFDrXqBYf3e4uJRyi7wsPxclE11sC1Cpfuk2belEgTpgL01VZmnjDNaHlHMt6h2K4XClt8tIgxbuKuwOJ9_iAy3mvhmxMLasx2Pr5fJIEVtQJsk8hQvaVCNHJX4inux2ARebdSnbPFtCusU235PezWfMFQkEpwNuPAK7IvwplGHuOLIE8Ro7_X_JuboI.bmV2BbwLo5RwFbyXceTNjdvgRwqBT9_gZ5RVmUkHUR8&dib_tag=se&keywords=G1+iem&qid=1774358535&sprefix=g1+iem%2Caps%2C194&sr=8-2)

ye tuning mismatch between the iem and your preferences. was it the original zero blue or the zero reds. zero are also known for their pretty bad fit for a good amount of people with really chunky nozzles. if the blues weren't bassy enough for you you're probably a basshead and would enjoy something like 7hz legato

firstly OP's issue is that its a tuning mismatch. man prefers absolute bass cannon set and zero blues don't deliver that, very simple anyways if thats the case everyone who's plugging their hybrids straight into their pc would be **screwed** which I don't believe 100% plays out that way. ew300, em6l, zero reds without adapter, are some common sets people just plug and play gaming on pc but also listen to for music I just happen to filter those ones because their common use on PC. gaming performance would also be screwed if their intended sound signature was completely 'destroyed' and i believe you would see a landslide of complaints supermix i've seen are particularily sensitive which I'll agree with tuning changes that i've seen so I don't completely disagree. but for *every single* hybrid and multi driver to be **destroyed** in tuning thats just very hyperbolic Either way thats my humble read on the matter. I stand by that blues tuning are *much* less bassy then the sony's presented too so I do believe that to be an issue of tuning mismatch if you're a fan of bass cannons so even if we were to grant the tuning of the blues to be guaranteed screwed, the 'stock' tuning of it would will likely still not be up to OP's preferences

truthear zero have some of the fattest nozzles in mainstream iems and cause discomfort issues for a good amount of people <50$ for gaming kefine klean is the best you can do, has a usb-c mic version. if you dont wnat usbc then you'll have to spend 10-15$\~ on a mic cable like tripowin grace
