Just a quick note. I've been listening to my latest purchase for a week now. The Audio Technica ATH-FC700: Yes, it's that sexy, but what Audio Technicas aren't ? But whatever. I have always been a very happy Sennheiser PX100 user. However, for my 'home setup', I used a Grado SR60. I had two complaints though: For portable use, the PX100 were very open For home use, the SR60's were too noisy for people around me I decided to go halfway. I wanted a headphone that would have some isolation for outside, but I was also gonna use it inside for 'proper listening'. Furthermore, it should be good to go unamped and not be too expensive. So I got the ATH-FC700. From eBay nonetheless. Since they are not the most popular or demanded phones, no fakes are circulating, luckily. The Sound: I must say I am very impressed by these phones! A very 'rounded' sound, slightly leaning towards the bass. To compare them to the PX100: mids are about the same, the ATH-FC700's high are a little more detailed, while the PX100's bass has a little more punch. Oveall the ATH-FC700 is much clearer though; in comparison the PX100 sounds like it's playing from behind a closed door. With the ATH-FC700 there is much less between you and the music This is all well and good, up untill this point, the ATH-FC700's are great, but not something to go crazy about. However, one thing really really surprised me about these headphones: they have great soundstage. Not something you'd expect from foldable, portable, isolating $60 phones. I'm serious, you've never been more happy your music is in stereo and more importantly, properly recorded and mixed. Some albums I loved on the PX100 now sound dull in comparison since all instruments are 'in the middle'. I head these on while biking and looked to the left to see if Miles Davis was really there, doing his solo. Then I peered into the distance, to discover the stage the White Stripes were playing on. But no, it's all happening inside this wondrous machine resting on your head. In short: I'm no audiophile, but I know good from bad sound. The ATH-FC700 are very decent sounding phones, for a very reasonable price and unlike most of it's competition, it grandly reproduces soundstage too. Try it if you can!
