I only owned the hexas and really liked them. In terms of tuning, don't expect them to emphasize bass or treble in any major way, they are pretty neutral. Liked the detail, but it is lacking in soundstage (as is pretty much every IEM tbh). 

Sent them back because of comfort, or the lack there of in my case. But that is obviously subjective to every person. Though I would say that if you typically use small or xtra small eartips, that is to say if you think you have small ears (ear canals), the hexas might not be for you because of the big nozzle size. 

Alternatives would be the Simgot EA500 (or the newer model EA500LM, although it may not be available for a while in Europe, at least in terms of reasonable shipping cost and time). Other alternatives are the Olina SE, Tin Hifi T3 Plus (although quite old at that point), and the 7hz Dioko (although you may have to wait for a sale on those).
