The delivery was swift and everything was nicely packaged. The AIAIAI E02 PU came in a nice little sealed bag, like the one's you get in a lego box. In the beginning I thought that these are a fad and that they probably make little to no difference at all. I have the E04 as a default when I produce or listen to music. The E02 clipped on easily as advertised, and I noticed a difference in the sound instantly. The lows are boosted more while the clarity in the mids fell. I tried listening to podcast with them and the voices were less clear than with the E04. I bought these specifically for DJ'ing and have found them to be performing really well, much better than the E04 because you can better hear the bass when you want to beatmatch. Works for me and I love how I can switch in less than a minute. Money well spent!
