My search for a sound I would be happy with began with the Sennheiser ie900s:
Pro: Coherent and Beautiful Bass and Very Fun Dynamics. Fairly wide soundstage with more of an "in your head" feeling. Physical size. Put them in and forget they are there. Amazing sound and detail retrieved from such a small package.
Con: Midrange a bit dry and treble can be spicy to some making taking breaks listening a must.
Campfire Audio Supermoons:
Pro: Technical Performance is outstanding. Very fast transients. Notes are crystal clear. Fairly wide soundstage with average perceived height.
Con: A bit clinical sounding to my ears. Best paired with warmer leaning source.
Campfire Audio Astrolith:
Pro: Technical Performance is outstanding. Very fast transients. Notes are crystal clear. BASS is bumpin with a bit of warmth making it a bit more fun that the Supermoon. Fairly wide soundstage with average perceived height.
Con: Sounds excellent but like the Supermoons, they need a bit more warmth as it can still be a bit dry. Use a warm leaning source and things are much better.
Empire Ears Raven (EER)
Pro: Unbelievable sound stage. Very wide, tall and deep. Bass delivery is OUTSTANDING! Midrange is so smooth with vocal realism that blows all of the above away in my opinion. The emotion in both male and female voices can actually be felt. Add in excellent instrument separation and placement, the sound is unreal. The EERs are warmer sounding than those listed above making them easy to listen to for long periods of time. They are not as peaky as the others listed but detail retrieval is next level. Bass texture is almost spooky. Notes are very clear and impactful.
Con: (Not really a Con just different) Holographic sound stage can be strange coming from iems that concentrate soundstage "between the ears". The soundstage can make some songs seem a bit too spread out and less dynamic if that makes sense. PRICE !!! Never thought I would need to add IEMs to my home owners insurance policy...
The crazy thing about the EERs I am getting this sound from a midrange DAP, iBasso DX180. I plan to move up a step to either the iBasso DX260 or A&K SE300.
Overall I am completely blown away by the EERs. They are truly remarkable IEMs and have totally ruined my ears. Worth every penny!
This is my first pair of high-end IEMs, and they are crazy. The bass is unreal! Shipping was fast, and I'm very satisfied!
Amazing, I never thought music could sound, or even feel, this good. Added bonus, wife likes them so they easily tank her aggro.
