Was this on the Atlas? For my first week with them, I had to be overly cautious when inserting them to avoid driver flex. After about a week, it seems to have gone away and Iāve seen other people report the same.
No, the Solaris. Sorry, didnāt mention it ācos itās the Solaris thread, I just came plowing in with my opinion 
Never heard the Atlas before
No, thatās why I asked. I assumed it was the Solaris, but I hadnāt heard anyone else mention that issue before. I did see it first-hand with the Atlas, and saw a few others posting similar issues. Driver flex is a weird sensation. You know the iem is deep in your ear, and you have ample volume, but the sound comes out muffled if at all. I can easily see someone picking up the Atlas, quickly jamming them in their ears, and thinking they were terrible if they didnāt know better
Ah cool. I wonder if itās certain IEMs with certain ear types - just the wrong combo for certain people.
Never experienced driver flex though, well not that Iām aware of. I looked it up to find out and despite two or three different descriptions Iām still not entirely sure what it actually is or what it sounds/feels like (I canāt even figure out if itās something you should hear or feel haha)
It mainly happens with iems that arenāt able to relive pressure buildup made from a good seal or donāt have proper venting, so you most likely wouldnāt have experienced it with the solaris. The atlas has a larger dynamic driver with somewhat inadequate venting imo that leads to the driver getting restricted or misaligned depending on the seal. Think of something similar to either electrostatics or thin diaphragm planars having driver flex or crinkle when a seal is made on your head and you push on the sides

To bring things back on topic a little more, I was using the Shure SE846 and happy for years. In a trip to NYC I stopped by Audio46 and listened to a few of the latest gen IEMs. Walked away with the Solaris, it was on another level vs the SE846.
The wind-in-the-port issue means I had to sell them, but I blame the Solaris for sending me on a new IEM journey years after I thought Iād found my endgame

Lol yeah, I am just getting into higher end iems as I have really always been a headphone person, but this canjam trip for me was pretty much just trying iems since I had heard all the headphones before lol
High end iems have come a long way, they just move too quickly for me to keep up with everything going on lol. I recall being impressed by the 846 awhile ago
Thanks @M0N. So itās closer in practice to ādriver inflexibleā, by which I mean the seal ends up preventing the driver from moving as it should?
Pretty much accurate

CanJam in London last year was where I replaced the Solaris. Itās been more and more ever since. Stupid Solaris, I should have never listened to them!
I shouldnāt have any problems with wind in the port syndrome as I only use them indoors
Out of interest what did you replace them with?
Ah, youāll be absolutely golden then, theyāre a great-sounding IEM.
I initially replaced them with the 64 Audio U18t, but I have those and a few others now. Not because the U18t wasnāt good enough (itās an amazing IEM for which Iāve since ordered custom tips), but because I caught āthe bugā again and have been enjoying experimenting with different sounds.

How did you find the U18t stacked up against the Solaris? as both the U18t and a8000ās are x2+ the price I can get the Solaris for 
Itās worth lol
The Solaris has, IMO, slightly better texture to the bass. As has been said many times before, thereās something about DD bass that just isnāt the same as BA, no matter how well-tuned. So on that level, I think the Solaris takes it. More impact, more slam, more textured and just a bit more natural sounding.
For everything else, though, the U18t is more suited to my tastes. The midrange is excellent. However where it truly shines, at least for me, is the treble. Iām not a detail freak and treble often annoys me and fatigues my ears/brain. I donāt usually chase sparkle, because I find it becomes annoying once youāre over the āwow, so much detailā phase. The U18t is different though. The best word I can think of to describe the treble is āsweetā. Smooth implies itās recessed, but sweet is better because it describes that itās present and noticeable, but not tiring. Loads of air and it never really tires me out (although it can show up on poorly recorded tracks, but lots of things can get a bit excitable when this happens).
Itās a huge price jump though, so as always, itās all about what is important to each listener. For me though, it was worth it, I really like the U18t and never regretted selling the Solaris, as nice as I find the sound on the Campfire flagship.

I need those xD
Thank you for your honest opinion I appreciate it 
all though iām not sure my bank balance will lolā¦hopefully I can listen to them along with the a8000 and a few others at CanJam UK and decide on which is the best bang for buck maybe the Tia Trio also 
Cool - see you at CanJam UK then. Trying to organise to meet up with some of the folks over on Head-Fi so feel free to hit me up on here if you want to have some people to hang out with for drinks on any of the days
Sorry - will stop derailing the thread now - more Solaris opinions please!!
