Budget gaming pick, but poor cables and polarizing bass.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
I have bought three pairs of these when the old pair broke. Use them for gaming and gym. Big fan
As IEM I use the LD Systems MEI 1000 G2. Very solid and never had any issues. For wireless, I use a Line6 G50 Paid around 300€ for the LD and 100€ for the used (pretty beaten up) G50. Using IEM for the first time is tricky, specially because you are probably expecting to have definition and dynamics in volume and it’s not quite perfect. Huge stages tend to give you better conditions for a nice EQ than small ones since you have much more space and the drums can be far. But overall is amazing to get home after a gig and not be deaf. Oh, and I use KZ in-ears. Z10 Pro S and Zar. Amazing value for the money.
The KZ-ZS10 Pros were my first iems and they rock!
The IEM you bought is a single dynamic driver. Try the Linsoul KZ ZS10 Pro, 4BA+1DD 5 Driver instead. Each driver set to play a frequency range. This really openend my eyes in the ability of cheap IEM over expensive headphones/in ears.
We have really good in-ear monitors now, no need for bulky headsets. Monitors will allow him to hear himself much better as well without needed to pipe his own playing back in to him. I usually suggest these to the budget conscious parents of by students. [https://www.amazon.com/dp/B07XXX7Q4H](https://www.amazon.com/dp/B07XXX7Q4H) They get much, much more expensive than these. These are just to trial to see if the player will actually use them and get any benefit. As far as a recording/playback setup, big can of worms. I'll leave others to that.
Agree. I've used 215s, 425s, some UEs (don't remember the model) and currently use ZS10 Pros with foam tips. For what I do, the ZS10s are the best. The 215 and 425 are not worth the cost IMHO - they were the most comfortable to wear, but I only used them with the stock silicone dome tips and they never had enough lows nor enough isolation. The ZS10 were better sounding with stock tips, and then the foam just made them even better. You didn't say what you play. For reference, I drum at church, so it's acoustic drums playing rock style music but not super heavy, for a couple hours a week. If I was playing professionally or otherwise for significantly more time, I'd get customs that were more comfortable than the ZS10s.
I'd try the cheaper Amazon ones (KZ ZS10 Pro for example). I use those regularly, but I've also used Shure 215 and 425. Frankly, I love the fit and feel of the Shures but don't love the sound. My KZ are WAY better than either, especially once I switched to foam tips on them. The Shure's just aren't worth the money.
