Thanks for the reply and information. I see that you have EX1000, HD650 and had IE80, and I also own all 3. Could you please compare the sound signature of the Jupiter with those? Thanks
Well first off, the EX1000 is my personal favorite dynamic driver earphone of all time. Its also almost 7 years old now but it still has the absolute best quality bass texture and extension I've heard in an IEM. Jupiter doesn't really come close there for me, in both extension and quality. This could be arguable, but I'm a dynamic driver bass fan over balanced armature bass. However, its mids and highs are much smoother than the EX1000. As you own the EXK you probably know there is a nasty surprise known as a treble peak that sometimes rears its head on certain tracks. In terms of soundstage jupiter also doesn't come close to the airiness and openness of the ex1000, but the ex1000 can become fatiguing after a couple hours whereas jupiter's neutral but smooth sound. While the ex1000 is a V shaped signature, the jupiter is more along the lines of neutral, though there is a noticeable dip in the upper mids on the jupiter to prevent harshness but some say that throws the timbre off. Detail retrieval on both is pretty close, but I'll give the advantage to the jupiter for its quick moving quad armature design.
The IE80 was one of my first "higher" end iems, so although its not technically that good it still holds a special place in my heart. Its even more V-shaped than the ex1000, and it has massive mid bass. For me that's not a good thing as I prefer subbass over a midbass bloat. Overall tonality if I remember was dark, and it does not elicit as many details as either the ex1000 nor the jupiter. Soundstage is about the same as the jupiter from what I remember, but overall mids were too veiled for my tastes. The IE80 would not be a dynamic IEM that I'd say competes in the ballpark with the likes of the jupiter.
Onto the HD650, the closest to soundstage you'll get to the hd650 out of the 3 iems would be the ex1000, though still not really close because HD650 cheats by being an open back full sized headphone. Sound signature wise I think it is the closest to the jupiter, in that both are neutral sound signatures with no apparent emphasis on any specific frequency across the board.
If you're looking to upgrade your IEMs for noticeably better sound and you own the EX1000, IE80, and HD650 already the only true benefit of getting the jupiter would be a better fit/isolation if you wear them outside. My ex1000 live in my house because wind noise and lack of isolation make it hard to use outside. Depending on what you listen to and prioritize in your sound the Jupiter will either be an upgrade or a sidegrade to the ex1000's, for its asking price of $799 new I would not buy it, but for a little more than $500 on the deals website or black friday sales I think its practically a steal.
