8 people saw me with my new FiiO E5 and asked stuff like "What is that?" "Why do you have two nanos" "Dude you have a knockoff nano connected to your real nano?!?". A few kids suggested I clip them together. Unfortunately, the clips are not similar so it doesn't work...
6 of them tried it out, 3 of them saying that "Everything sounds a bit better" "Wow, thats balls" (In a good way), and "Cool, how much was that? $15? Thats cheap" my friend who appears to be lightly getting into better audio (He is eyeing some Portapros or Meelectronics M6s) said "Finally, your damn bass doesn't kill the rest of your music" (I always have my iPod on treble booster because of my K518LE's crazy bass), the only other audiophile I know said "Congrats, I've been looking at getting one, and one, who tried it with his Skullcandy Ink'd IEMs, said there was "no difference".
Overall, quite a few were intrigued, and overall a positive response. I either get positive raves or indifferent opinions on my cans, and because I wear my iPod (and today my amp) on my shirt, what I'm listening to and how is pretty visible. The K518s give better impressions than my iGrados.
