Ok now I have to edit a characteristic of the Piston I just observed from more source experimentation. ThatBeatsGuy tipped me off with a comment he made earlier. The Piston DONT SYNERGIZE well with AMPS. Listening to the Piston through the Sansa Fuze without the amp, they sound vibrant, clear, and controlled, as opposed to grainy and bass flabby when amped. So unamped with the Sansa, Sony, and iPod, they really sing. Just such a balanced and dynamic sound. So engaging and forward. The X3 has a built in amp, so they suffer while going through the X3. The OM Audio, UE 700, and Trumpets don't have such issues with the X3. They love it and the X3 loves them. Just a little something for those of you with Piston 2.0 and amps.
I've been listening to mine through the E12 + Zune 120, and I find the synergy quite awesome. On that note, I tested the Pistons in a loud environment where I needed the volume up quite a bit more. Unlike other $20 IEMs I've used, these Pistons can handle louder volumes with nearly no harshness at all. So many good things about this IEM!
