Phonak Audéo PFE 232

SUCH PERFECTION!!! WITH ONLY TWO DRIVERS!?
 
i know it's kinda late to write this... since this gem is discontinued already..
but lemme tell yaa.. great things are everlasting.. even with many more competitors with more drivers
phonak pfe series still hold their own league and uniqueness 
 
ergonomics:
oh boy..... they are comfortable.. and i mean... extremely comfortable, i could say they have the best comfort for universal iem
and i've tried brands that are known for their comfort such as shure, westone, and even inear stage diver, and i could say that phonak's comfort totally hit the sweet spot
it's a perfect housing
 
the cable itself is also good and feels durable.. but sometimes i could hear a little microphonics.. 
oh yeah and it is detachable but with their own connector, so it's kinda hard to find a replacement, but you got 2 cables inside the package 1 with mic, and 1 without
 
sound quality:
i've tried all of it's filters but love the gray one much more that the others, black filter add more warmth to the mid and the green one give more warmth than enough.. it's too warm and too bassy with green filter
 
this review is gray filter based only
phonak 232 take a different approach from it's lower level such as 012,112,and 132
with it's dual Balanced Armature drivers, it provides more bass and sounds more v shaped than other phonak series but still maintain a clear vocal
 
bass : reach quite low, as a dynamic driver lover.. i found this phonak's bass is really acceptable and even exceeded my expectation for dual Balanced Armature
really..really great with punch but with soft texture, the bass is truly remarkable
 
mid : really clear but smooth, non fatiguing... such high quality mids, but if you're a vocal lover maybe you should try the 112 or 132 i think their vocal is clearer but less smooth
 
treble : how could i describe this??? smooth, non fatiguing with the best timbre i've ever heard!!! damn phonak!! great jobb!!! it's really rare to hear such treble even with higher price iems
a treble perfection for me, the timbre is just spot on argghh i'm at loss for words
 
soundstage, imaging, and separation : 
i should say that this iem is airy but it's width is it's weak spot if you're craving for soundstage width, but luckily the depth is there!! and it's good! gives a subtle 3d feelings to the music.
imaging and separation is also great and definitely high-class, sometimes it's quite revealing, when you hear a badly recorded lossy files, you won't get the separation, but play a good quality instead
you can pinpoint where the instruments are...
 
with only two drivers... phonak... you rock!!!
easily one of the best iem i've ever heard!!

Being out of production for a few years, I had to hunt this pair down for a few months before I could get my hands on it. And boy was it amazing.
 
Everything sounds fantastic out of this set of IEMs, but put on a track with strings (violins, cello) and feel the hairs on your head tingle. Overall warm & bright signature. Instruments are vivid & accurate. Treble extension is amazing. 
 
Con is if you're a basshead you'll find these slightly disappointing. Also, there is a lack of aftermarket parts (the cable while detachable, is not easily replaceable as it's a custom made)
 
If you manage to see one of these lying around, please grab immediately (regardless of price) - it is worth it. 

These iem's are amongst the best universals I've heard.  Their sound signature (tunable with filters) is mostly v-shaped but remains very pleasant and detailed.  They're quite expensive but their scalability and amazing highs extension only justify the asked price for me.  I think they deserve a very good source and amplification otherwise they're not much better than other cheaper offerings.  Another strength of these in ears are their comfort which is very hard to find elsewhere (they're very light and small so it's easy to get a good fit).  Overall, I'm very happy to own them.
