My read is these are more “musical”, more rock n’ roll than “balanced” - the latter I tend to think of as linear, with basically the bass side of things dialled down and relatively more emphasis on the mid to highs. So everything sounds “clear and fast”. The ultimate reference is probably Shure KSE1500.
But we all bring very different notions of “reference versus coloured”. On this forum there are threads dedicated to the semantic challenge of describing what we mean by our impressions of hi-fi.
I’ve also had a pretty decent testing of high end iems, not everything obviously. The u18 is probably the most impressive iem I’ve ever heard, but if I pay $4k on a pair of iems I’m going to get divorced... (actually we live in sin, but you get the idea).
Similarly a heavy listening session of some high end iems, made me super impressed with this line of iems. Historically I’ve mainly bought Nobles, Shures Westones but needed to get out of that rut. The above are all good, but sometimes you need a change... Happy listening all! I hope this thread grows, maybe the recent downward price adjustment will drive sales, and hence more feedback on this forum thread.
Pardon my clumsy wording. What I meant by reference core sound + fun turning might be better described by saying "natural" + "musical". I tend to prefer "reference" and "analytical" tunings, so I'm pretty sensitive to exaggerated curves, and I found the JHA 13v2 very enjoyable, a good value at $1k, and a well rounded IEM that would sound fine for a wide variety of musical genres.
This was the first time, I had the opportunity to listen to so many high-end IEMs at one time with my own source. If you have time to get to a shop like E-earphone in Tokyo (or Jaben in Hong Kong, etc) it is well worth the time and effort. You can instantly get a sense of each manufacture's "house sound" and it is great to do both a "vertical" comparison by listening to a single manufacture's models (cheap to expensive) and also do a "horizontal" comparison by listening across a bunch of manufacturers at a specific price point. One other point about E-earphones that I really appreciate is that all the IEMs are set up to try yourself and you don't have to ask a sales person for each demo. This makes things casual, allowing you to do things like go back and forth a millions times between two IEMs without bothering, taking as much time as you like, without any sales pressure. The downside is that if the store is busy you might have to wait a bit to get to the IEMs you came to listen to, but the upside is that you can listen to something new while you wait.
