Joining the rest of a collection of flagship and myriad high-end IEM's, these new Andromedas have quickly become my new everyday/go-to staple - displacing the venerable and exceedingly rare Andromeda Gold. The Emerald Sea have clearly taken a step up in terms of overall sound quality - bringing the Andromeda up to a level where it is now much more directly comparable to IEM's like U12T, etc. Again, just my humble opinion - but for whatever it's worth - zero buyers remorse here. Couldn't be happier. I am using my set with an ALO Smokey Litz Lite cable (instead of any of the included 3 cables). I just find the Smokey Lite to be more comfortable and better looking, an overall better fit for a pair of IEM's I take with me everywhere.
The Emerald Sea has entirely replaced my Andromeda 2020 as my favorite IEM. Highs are more extended, bass goes deeper and has more impact. Mids are creamy and resolving. I love these IEMs so much. It isn’t a huge leap above the Andromeda 2020, but an evolution worthy of the new packaging and title. They are simply lovely. And the cables are spectacular.
