I can get this set for 50 euros, instead of the normal 100, through the Dutch iBood. The problem is that I don't know if I can expect any audio quality. http://assets.eu.denon.com/DocumentMaster/NL/AH-C120_EN02-1%5B1%5D.pdf

I don't know much about Denon, and info about this set is particularly scarce. But I've been thinking about buying some not too expensive in-ears for a while, and I would like something with a rather natural sound (and as such the flat frequency response Denon claims this set had would be a positive thing). What I want is everything Denon claims this set is: not too expensive (although a few bucks more costly than what I was planning to spend), it has a built-in microphone for phones, and a flat frequency response. But well, OEMs can claim a lot without delivering any quality, we've got enough examples of that (Beats, I'm looking at you).
 
So the real question is, are these IEMs good bang for the buck? Or should I just go with some cheap Sennheisers or something?

I just bought those ones with reduced price, must say im very happy about.
The sound is very good, balanced, no overblown bass, no harsh (Sony kind) treble, sound stage is incredibly wide for in ear monitor, nevertheless they shining only after some time of brake in. Reasonably comfortable construction although im not a big fan of extensive wiring but the cables on C120 looks and feels very sturdy and could be used for a extended amount of time. 
In short i'll recommend this pair for anybody who would like to have more or less Hi-Fi sound on the go without extremely big investments, its a five star product!
