To be clear, I never had any problems with my Hive, dust or otherwise, and Sajeev is a great guy. But yeah, the fact that they didn’t have dust covers and I live in a smoggy dusty city worried me. The Nectars were much more mid centric, less air and shimmer, but they didn’t have the Kaldas’ sub bass. That’s why I think of them as the estat 6XX.
I’d say the L300, the Kaldas and the Hive are near equals technically - one has air and shimmer and the extra detail that that brings, the next has sub bass and warmth and the third had ‘sweet’ mids but rolled off on the bottom and the top. Pick your flavor.
