mate sorry, i did not want to push anything on you.
perhaps you must ask people with extensive experience with both. i auditioned K3003 briefly from another head-fier who kindly brought them when collecting a touring 1+2 unit from me. from our impressions, his and mine, K3003 had a similar signature and sounded in many aspects as good. i preferred 1+2 for more crisp sound and taught bass, he preferred less aggressive more laid back sig of K3003 despite liking 1+2 a lot too. he also briefly auditioned my H200 and we agreed that H200 is very interesting IEM and excellent proposition for 250$.
yeah, price difference is huge, so if you divide sound per buck paid i suppose both IEMs will be even but sonically they are different leagues of course :-D
i am listening now to RDB+V1 on BH + C3 and i can say V1 sounds cleaner and more detailed compared to H200... still H200 holds its own offering mellow, enveloping sound communicating a fair amount of detail and good (but not great) dynamic. perhaps surprisingly H200 has a bit better bass extension for my liking, V1 despite having very airy presentation lacks stronger attack and punch. i find V1 brighter and more forward sounding, sometimes overly aggressive in trebles which can be too hot, this is more mid centric compared to 1+2, still plenty of musical information, spacious airy stage especially good 2D and instrument placement goes further away is what makes V1 shine. this is so good sounding that i now begin to think against selling it, V1 is nice IEM which shines with acoustic and small chamber music like i always said.
now what else i must say? everything has its price.
