Just got these in yesterday.
Initial impressions are that it’s a pretty likeable set. Overall tonality is U-shaped, but whereas I find my RS1s to be U-shaped but focused, maybe even analytical, Sora 2 is U-shaped but lush, smooth, full-sounding. I like my vocals and these seem to deliver for the most part. Natural, organic, quite detailed, but maybe I’d like a tad more crispness and body, especially for male vocals. Treble is well-extended but not in any way intense or unforgiving. Cymbal definition is especially impressive, a step above the RS1 even.
Comfort is excellent as with most bullet-shaped IEMs. Not a massive fan of the cable as it constantly wants to work itself into a coil. Box contents and presentation is barebones but I don’t care since the box will end up in recycling.
Impressions above were given with stock tips. Having switched over to my favourite Azla SednaEarfit Standards, the overall sound is still lush and musical but I think they bring the mids a slight bit forward such that vocals are tighter.
