Summary: I switched from $40 Sony and Sure to this IE6 and I'm glad I did. My first impression was so great and now I can enjoy my music collection while walking my dog. Please notice that you can use IE6 with or without the flexible ears holders.
Pros: Well build, great sound, no extra noise from cables while you walking, comfortable, good base.
Summary: These are expensive headphones, and they (probably) do not offer a significant enough advantage over some cheaper headphones that cost under a 100$, but that is for you to decide. I'm thinking along the lines of the Z-buds or the cheaper Sennheiser earbuds.
Pros: The sound is absolutely fantastic, with strong mids and treble and an enhanced bass output when compared to the ultimate ears superfi5pros. Takes some burning in (as with all good headphones) and starts sounding better and better with use. The sound is still improving with more use 1 month after ...
Summary: First of all the product is delivered on time as advertised. And the product is as good as advertised. No issues in about a month's time and the noise cancelling function is good. I do recommend these headphones. At this price this is a GOOD BUY.
Summary: I got these for Christmas a couple of years ago and love them for flying. Just turn on the noise cancelling and you don't hear squat except the movie you are watching. The only draw back is you can't wear them while the plane is landing or taxiing so I have missed the end of a couple movies.
