Always looking at this Thread, but find no body seems have interest, and I think Campfire already take out Polaris from their portfolio. . And also that's irony of middle segment, threat it like middle child, must compromise the oldest and Compliant to the youngest... so middle will never shine....
Just giving my thought after using Polaris for 5 months, as my companion in Commutering in the morning and afternoon. Each trip, I listen for 1 - 2.5 hours. Or when I had Biztrip in plane.... this is the IEM that my hand always want to reach.
Previously, I always bring / use earbud from my iphone 5 with me to accompany my daily audio commuting.
My opinion, Polaris is unique Character, Hybrid that want to reach the best of each side, Dynamic Low, Sparking High, with a mount of Mid. compromising each to get optimal output of each frequency...
The Fun Factor for this IEM, IMO, make regular song sound different, and WoW effect appears, I believe this Campfire magic shine. I only use spotify (premium), more comfy and easy (Yes it consume big Data).
Using DAP or Stack it with proper Amp will be audio privileged, but not convenient for holding thick stack. So my Mobile phone will be the better option, Handy and easy. .
Sorry, this is not a review or a brag about how good Polaris are... But for me, this IEM is not easy to be replace.. have try & audition Andromeda OG & SS, Shure, Accoustone, Dita Dream... each are great IEM with their own unique ness, but still not making me away from polaris...
I really want to know Solaris, since it's like Polaris bigger bro...
I am just a daily audio user, looking for a better Audio quality on mobile uses..
My suggestion for using Polaris, based on my experience, is pairing with Warm DAP and get that clear detail sparkle...
recently, I bought Ref 8 Cable, and try with Polaris, not a great move for me, the microphonic effect is really annoying when the cable touch your sleeve or your skin... But the amount of detail from it is amazing.. just plug to my Note 8, alrd satisfied me.
