Headfonics's review of the Final Audio Heaven VIII, about which I left a Brazilian strip of commentary, is a pretty good read, with which I mostly agree. That is, apart from the following:

“The treble of the Heaven VIII renders very well and typically has the great levels of extension and detail a balanced-armature driver provides. In drum and bass tracks, high hats decay fast and efficiently without being laidback in nature. In this sense, there is no spatial disconnect from the upper mids to the lower trebles which both share a sense of brightness in character. The sparkly clear highs make for an engaging presentation and truly satisfy those seeking extended highs without the compromise of rolled-off frequencies.”

Heaven VIII lacks the upper mid heat that has made a number of hi-end Final Audio earphones hard to listen to for long periods of time. VIII is smoother, and comparison to hitherto news-making balanced armature earphones from Final Audio, rolled off. It's got none of the dirty decay that accented some of the other mid-top end earphones. For that, I'm glad.

The Headfonics review is a good, pithy review of a good, pithy earphone.
