Ok, I finally received these today. It took exactly two weeks for the package to arrive to my door from Russia. I was very excited. Having read this wonderful review as well as raving reviews and impressions from some Russian forums, I was hoping that these would be giant killers, considering that according to many they compete with or even outperform Sennheiser HD6** series and Beyerdynamic DT880. Ok so here are my first impressions:
I plugged them into my Samsung T9 portable player, put on some trance music (good quality recording in 320 kbps or 256, can't remember, but good enough) and hit the play button. The first thing that struck me was the deep, tight and powerful bass. Very nice. The next thing I noticed was that the soundstage had good depth, but a bit lacking in width. The 'phones clearly sounded closed in, although imaging and depth was very good. Next, I found the upper mids to be a bit overemphasized - not harsh or grainy, just a little too pronounced. I listened for a little bit more and noted that the sound is quite laid back - not dark, but soft. Detail is good, especially micro detail, but a little smeared/muddy. Clarity is quite good as well. So far, these can't match my EarSonics SM3 and are not quite as defined sounding as my Shure SRH750 DJ, but I can certainly sense the potential. A better source and more burn in will hopefully help.
Here is a frequency response graph I made of the FA-003, as I hear them with my ears. I used used my Audigy 2 ZS with kxProject drivers as source. Remember that these are not burned in yet - they have 1 hour on them at most:
For comparison, here is a relatively well burned in Shure SRH750 DJ (60 hours). Same source:
And here's my reference - the $400 EarSonics SM3 universal fit IEM. Again, the same source:
