Despite the other person's comment most IEMs are pretty easy to drive. The one thing you may want to make sure of, if you can, is to plug them into your mobo and not just the case port. That can make a difference.
If you go mobile most people seem to say dongle is enough. I got a qudelix and like it quite a bit. The software is well done and easy to work with.
I mean they also dominated the universal remote market, drove out all competitors, and then just let it die... Must be their kink
I understand that it can be difficult to save money. It can be difficult to hold off and wait until some chips have stacked and to actually upgrade. It feels weird seeing people with 20 pairs of IEMs and chasing all the different tunings when, with the money spent to this point, they could have purchased a very serious upgrade. Like "I can drop $1k over the course of two years on sub-$100 sets but the thought of just waiting for a while so I could drop $300-$500 on something SERIOUS is abhorrent." But to each their own. If you really enjoy collecting like that then more power to you, just my perception of the habit. It starts to look compulsive.
I mean my stereo attached to my computer is my best "audio device" but this is the wrong subreddit for that. So I have a Schiit Jotunheim running my ZMF Auteurs and with EQ it is pretty much jaw dropping and I love it. They are what I use for gaming, and they're ok for that, but then I run them with only a bass shelf. For music I run a modified auto eq in Peace and yeah, for that they're unbelievably good. I don't listen to them during the day because I can just have my stereo on most of the time, or I'm moving around and have my Sony earbuds in. I'm still on the fence about my IEMs, they have a much cleaner sound than the buds, but I may have got the wrong IEMs for my music tastes, which are bass heavy. We'll see if they stick around.
Music-wise a little of everything, but heavier into rap, hip-hop, some electronic, and a lot of poppier things.
