Yesterday and today I went through this thread twice in anticipation of delivery today of my new TDK BA200 earphones. I had dialed back my expectations. I open the package, put them in my ears (expecting a bad fit, or extreme discomfort, but experiencing neither). Plug them into my Fiio E17 DAC/Amp to listen to high bit-rate mp3s on the computer. I'm waiting for the low-impact bass, and rolled off highs. OK. Here we go.
WOW ---- these sound GREAT! There's nothing like dialing back one's expectations. The clarity is striking. The bass goes down LOW, not muddy, not overemphasized, just clear. True, my eardrums aren't being blown into my head by the impact. Is that sibilance I'm hearing? Where are the rolled off highs?
After 15 minutes of listening I'm second guessing myself. Am I missing an octave up top? Now I'm not sure. I punch up the treble on the EQ. Hmm, sounds better. Maybe these ARE a bit "laid back". Not sure.
Let's see how they sound unamped out of my Sansa Fuze. They sound very good. OK. Now I hear that maybe they ARE missing a little bit of sizzle. But I'm not getting that congested, muddy sound I first heard out of my W4s (I'm now convinced the W4 needs to be amped to sound good).
I've only used the one set of tips (the larger double flange that comes pre-installed). I'll have to play some more with other tips, but overall, out of the, I'm pleasantly surprised.
