Lol Campfire. They're like Rolex, if Rolex could only sell submariners from the 60's, and didn't have any certifications like COSC or such.
They chose to sell to audiophools (with their silly cables, which actually sucked yet still cost quite a bit, of which are only now getting refreshes as of late), and when measurement folks got ahold of their IEM's every single one of them have been failures in one form or another on the market since the Andromedas. The only reason the Andromeda had staying power, is that was a time where not much measuring was going on, so the prestige had settled-in with their regular repeat customers who also enjoy showing off their halo product on various social media and such, and as such they've tried not messing with that forumla too much.
The only reason the Andromeda isn't $300, is due to the aluminum casing (which in my opinion actually sucked as much as the idiotic design choice for Audeze LCD-line of headbands), the US-based operation, and the decent warranty.
They should try throwing some money at R&D + QC'ing for driver consistency, and driver channel matching tbh. I've heard 3 pairs, each once had one of these "flaws" in some form or another.
It's laughable it took them this long to attempt to mitigate the issue with the annodization chipping for example (idiotic highly angular/sharp corners of the IEM), and their pathetic nozzle length basically requiring foam tips be used if you want proper deep insertion that doesn't have them sliding out of your ear.
I could go on with various cable complaints, questionable sensitivity levels, and more.. (at $1000 for an IEM, yes I will be grilling everything). Instead I saved myself the headache, and got something I don't have concerns with, know performs better, and doesn't cost an arm and a leg. Only problem for future folks.. They discontinued them (as is usually the case with half decent products).
Moondrop Kanas Pro. I'm still waiting to see anything that has consistent measurements/more comfortable/ergonomic/better looking, at the price. (Sadly replaced by the worse designed Moondrop KXXS but still a very good IEM compared to others generally speaking).
