If it helps I have both the Hexa and Aria and can compare if you know what Arias sound like. Hexas are much leaner, this can either mean cleaner or thinner depending on your tastes. (For me it is a bit thin) More coherent than the Arias but have very little bass, though what it does have is well controlled. I would put them slightly ahead in terms of resolution but I find the Arias have a much fuller and more exciting sound with a satisfying bass slam that works well with all genres. The midrange can sound wonky but only if you switch back and forth between pairs a lot. Also the Hexa's nozzles are massive and a lot of 3rd party tips just wont fit lol. The tips they have are fine though.

Personally I would take the Aria, they just have more fun factor which is what I think should be the main priority at that price range. Hexas are actually a lot better for online gaming though particularly shooters because a lot of bass with gunfire makes it hard to hear anything else.
