Headphoneus Supremus
Listening to Phoenix I just forget that I am evaluating an IEM, it’s so musical, smooth, textured, (insert here any word you would use for this type of sound). As soon as I put it I get into relax mode. It’s been a hard impressions to put together. It is a good thing, because the majority of my use case is just enjoying music not analysing it.The Phonix is really a solid choice and can handle easily by any source. It has it best detail available out there and it is a very pleasant tunned all rounder. While my experience with the EXT is really good, but I have to point out that for some source it can be under powered. When it is powered by an external amp or portable amp, the EXT can have a very wide sound stage, almost like the Phonix.
The EXT may require a bit more effort in your hobby to unleash it's full potential. While the Phonix is an easier IEM to handle.
EXT is a less smooth, but lot more clear with, as the name say, extended extremes of the frequency.
