Yeah I almost pulled the trigger on 11.11. The price was around $110 with all the coupons, which is quite attempting for a pure beryllium new release. I decided to wait for more feedbacks, and ended up going with MT300 + Cyberfox T1 as the alternative purchase.
There's a bit skepticism over the 'pure berryium' claim, as the material cost is very high for earphones of this price range. There's some reviewer asked for pictures of the driver diagram, Kbear never replied. But who cares if they actually sound good. Based on the graphs that found online. Believe still shares a bit similarity with Kbear Diamond. Probably a bit less bass and different treble characteristics for a big V.

I also found them similar to Moondrop SSR for mid range graphs. Of course with elevated bass and far extended treble. I'm still on the fence because of that huge recession around 1K, but they are probably technical superior, and also aesthetic pleasing.
