>>1944601there seems to be a lot of debate about what works best and it probably varies from person to person. in my opinion the most important thing for enjoying spatialized sound effects is going to be a smooth upper midrange and treble response, whatever happens to sound natural to you (and opinions vary about that too). the question of open or closed probably depends on how much background noise you have in your room. for ASMR i use multi-driver balanced armature IEMs because i like the sound isolation and the spatial sound effects sound natural to me, but it may be different for you. for music i use a few different pairs of headphones, some dynamic and some planar, and they all have their strengths and weaknesses, but i don't think there is anything inherent to planar drivers that is likely to make them better or worse for ASMR in general.
