WEESTENOSISThey're different categories (earbud vs IEM) but the SA7 is much more detailed overall. I've been demoing our sample over the last few days and they're definitely the best IEMs i've heard in this price range. Even against a quad driver like the UE900, they're much better.
WEESTENOSISMy SA6 are far better than PK1 and on par with my Dasetn M760 which are the best earbuds on the market imho, so I hope SA7 will be the king of them all. ;)
