100+ Head-Fier
The 750's were my first dive into iem's so I assumed that's the comfort that i'd expect with iem's in general. You're right when you say these feel weightless it's surprising
not the most comfy ive tried. the campfire audio orion at least is way more comfy. also the westone UM1. i guess due to both being small and light plus both have a thinner & more flexible cable than the standard RHA cable. I'm sure the angle of the nozzle plus the insertion depth plays a big role too.
