500+ Head-Fier
Not unlike comparing the HD6XX/HD58X to say the HD800. Is the extra ~$600 justified? Up to the listener and how much you value the small details I guess.
Not saying this particular bud will live up to its TOTL price but in general the case is how much you value small improvements all round.
Hence why I'll probably be buying the new $400+ K's bud in 2 months
Ehh... most of these buds are using the same housings as much cheaper equivalents. I'm not saying they sound the same, but the difference in R&D for an HD6XX vs. an HD800 is likely quite a bit higher. I really enjoy earbuds now as well and have racked up quite a collection (with Willsounds PK16 on the way). But I would never drop more than $100 on a pair unless there was something under $200 that would actually sound better than my AKG 7XX in every way.
