I actually was able to trade it back to Campfire for the Andro 2020. The Solstice (audiophile fit) is the most comfortable custom I have ever worn and loved using it for that. I cannot emphasize how comfortable it is and I have 2 other customs.
Reason why I don't have it anymore is it didn't sound like an Andromeda to me which is what I wanted and I know others have said a similar opinion. It sounds like it based on the Andromeda, but the Andromeda had this special tuning to it especially with its upper-mids and highs and the Solstice didn't have that. The Solstice sounded like a smoothed out Andromeda in terms of frequency response to my ears. I tried both the Andromeda 2019 and 2020 side-by-side with my Solstice and both 2019 and 2020 Andromedas had that special sauce that I was craving that the Solstice didn't have.
I sent it back wondering if the measurements were wrong on my version since I purchased it the day it came out and according to them, it measures extremely close to the Andromeda. After long discussion, they allowed me to trade it in and I am much happier now with the Andro 2020. Might be good to keep in mind, I am really picky in how I like my sound, so you might enjoy it.
