For me, wired multi-driver armature IEMs (in-ear monitors) are the best thing to happen in the audio field since the arrival of neodymium magnets.

For a fraction of price of professional monitor speakers, you get the closest thing to direct hardware-to-brain audio transmission. It's precise and fast transient-wise.

No reflections, no phase problems, nada. You can choose exactly the type of frequency response you need: flat, V-shaped, U-shaped, bassy, bright, whatever. There are even models with switchable curves.

No need to invest much more money than your speakers cost in your listening room, installing wool/foam pads/draping/soft furniture/bass traps/carpets etc to reduce the amount of reflections and bring frequency responce to anything resembling flat.

That said, there is a huge number of IEMs produced these days and they range from absolute trash to stellar. And to navigate this vast ocean, I find Crinnacle's resourses utterly useful:
