Well, let me tell you my story. I have purchased LTD's and never expected to receive good sounding earphone. It was a risk and I was going to live with any result I'd get. From other opinions, it was clear they are good to the point you can just enjoy them and listen to the music. Well, (I don't have to tell you) any headphones should sound like a good hi-fi system- natural, engaging and "as performer intended". These IEM's deliver natural, undistorted sound with good spatial presentation and every instrument sounds real. I always seek sound reproduction of real instruments to be as close as possible to the original. Am fully satisfied now. My friend quietly purchased LTD's too without saying anything, but now I am being bombarded on skype with links to the music he has just rediscovered. Every day for the last few days, tens of messages. A question whether they worth RRP? Possible, but with prices above 100£ I would always go for the cans, not IEM's. At the moment I am screwed- B&O H6 I wanted to buy will have to wait. Indefinitely long.
