Guys whats the best chi-fi for $150? Tried Starfield and didn't like it at all - tiny sound with lots of detail lost. Also tried ZSX - liked it better, but it's a bit too bright to my taste, so kinda tiring.
Most important things for me are soundstage, detail and isolation, also bass should be accurate. I listen to electronic music (ambient, house), classical and some modern indie-type stuff, no pop / EDM at all.
if you can stretch your budget a little bit, check on ISN H40, I've been hooked into them these past weeks, they sounded BIG, balance but not shouty at all, while still details but not tiring, tuning is very good in my opinion. They are quite sensitive but very airy, technicalities are above ZSX for sure, much wider and deeper soundstage with better layering with more natural soundstage than ZSX. Shell is quite big with protrude like ZSX, they are warmer than ZSX have very bold weighty mids yet still very clear.
I never heard starfield but I have Kanas Pro, the H40 is more details and fun and dynamic, I wont call the bass on H40 as fast but they are still faster than KP. KP mids sounded thinner if compared to H40. Isolation not the best but still better than KP and ZSX. looks like fit all your criteria except price.
Sounds to good to be true but this is not an advertisement, I bought mine full price, so my comments really aren't pushed by any hands here. I always tried to write my impressions honestly cause I care more about sound than manufacturer lol.
First time seeing this. Maybe the unit you demoed is defect unit. I don't think mine sound tiny or not detailed at all
perhaps as he mentioned he is listening to electronic, and more focused to highs about details, and starfield is very safe on trebles. Or he just want more. But as DD iems, starfield i believe isn't lack of details especially on mids (i assume they have similar presentation with KP / KXXS)
For $70 I think the DUNU DM-480 can fit your criteria of soundstage, details and isolation. It is a dual dynamic (DD) driver set but sounds like a multi BA set in terms of technicalities and details. Isolation is superb, around 25 dB passive attenuation, soundstage is wide. Bass is linearly descending with superb subbass extension/quantity, and the bass is very accurate and textured.
The timbre and note weight is not the best, especially for the mids/treble, so it may suffer for vocals and classical music due to the poorer timbre for voices/acoustic instruments compared to traditional dynamic driver setups. At this pricing, usually the dynamic driver type IEMs will suffer in technicalities/details compared to multi BA sets, so it's pretty hard to find something that excels in every department unless you go to a much higher pricing.
I'm pretty sure that there are better gear around the $150 price mark that can also fufill your criteria, though factoring in "good isolation" as per your post may exclude a lot of good sounding gear. Hope the others can chime in and good luck in your search!
for budget i also can recommend this the DM-480 have dual isobaric titanium DD that can cover bass line with fullness, they have details presentation too and wide soundstage.
@baskingshark already mentioned their pros and i concur about that. But remenber their mids can be on thin side, but assuming you're going for electronics (without vocals?) they can be your option too.
