Just got my R2As. Here are some way too early impressions using the Shozy Alien as my source.
They are incredibly spacious for IEMs and not just spacious but realistic sounding. You can hear sounds layered in across different distances in the soundstage and you can hear those distances change as say a voice gets further from the mic. It's just a remarkably real sounding experience of sound in space, for lack of better words. This is really the highlight of these for me.
Not only is the sense of space great, but the size of the sound is more like a headphone than an IEM. By that I mean you feel like you're listening to a real sized band with real sized instruments rather than a miniature version like with most IEMs.
Bass is great. Probably a bit more than neutral but not much bleed into the mids.
I don't hear deficient highs and I'm using the complys. They don't exaggerate the highs to accentuate detail, instead they let their excellent mids reveal details what to me sounds very naturally.
I tried the JVC spiral dots but they sounded thin.
The y splitter is absurdly clunky and heavy. But because of the seal of the complys they stay in the ears nevertheless.
Cable is ok. If I had sprung for the more expensive R2Pros I'd be disappointed though.
They are incredibly small.
They are signficantly better than the Rockets. Much bigger sounding, more spacious, better bass. Several leagues above the Tenores.
Given how good these are I'm in the paradoxical position of thinking I got an incredible steal for USD 120 but curious about how much better the R2Pros might sound.
