Pros: I thought at first, but I was very wrong. Literally, everything not listed in the cons is well done. FLAC + high quality gapless audio player + 192000hz SR + these babies = A whole new dimension of music.
Cons: A few small things that make this product kind of cheap overall. The cord is really thin, The actual cups on the headphones are only 4.5cm in diameter (see "Other Thoughts"), which I've actually found to be lighter and some convenient than large cups. Noise cancelling also seems kind of whimpy, but I seem to have incredibly sensitive ears, so that's probably just me.
Summary: My wife lost her first set travelling to Florida, she thinks someone lifted them from her bag which was open on the seat for 30 seconds. But, one should not wrongly accuse. She did not even want to try my Bose QC2's,she wanted the Sennheiser's back! I bought her a new set. She loves them.
Pros: Comfortable, Compact Design, Easy To Use, Great Sound Quality, Improved carry case
Summary: These noise canceling headphones are perfect for me. When riding the light rail train, I can still hear the announcements while listening to music on my blackberry at a comfortable volume, the sound quality is excellent and the built in volume control is a great feature. They fit comfortably over my glasses and earrings. I am very satisfied with this product. I love the compact size and carry case but the fold up design seems a bit delicate.
Pros: Comfortable, Compact Design, Easy To Use, Excellent value, Great Sound Quality
Pros: They do exactly what the description says they will. Audio quality is great. Mids are pronounced and bass is amazing for headphones. As far as comfort goes, I forget I'm even wearing them as soon as I put them on.
Cons: The cord has a controller in the middle for the noise canceling and volume controls. It's a little big, but has a clip on the back so it's not too bad.
Pros: Small profile and carrying case means it can slip into any computer bag / briefcase / purse / whatever. The metal headband is great - I generally put my headphones through their paces which means that I've lost/destroyed several pairs over the years. When I test headphones I usually put them through a number of tests and these performed as follows:
Cons: The airplane test was the only one where it didn't pass muster. I used these on a long flight from Baltimore to Los Angeles and while it was hard to hear the movie I was playing on my laptop (The Big Lebowski) - I could hear most of the movie's music and dialogue but still the sound of the airplane engines couldn't be blocked out from the noise cancelling filter. I also tried these out on AirTran's in-flight XM Radio and they worked pretty well but not 100% perfect. T...
Summary: This is my second Sennheiser noise cancelling headphone. They are fantastic for travelling due to the fold up design and compact carrying case. The PCX250II has some cleaver improvements over the older version, namely a volume control on the cord and a 90 degree stereo plug to fit snug in an airplane armrest. Are there better sounding headphones on the market? Sure, but you'll be hard pressed to find one as compact.
Summary: Really happy with them on my first 5 hour set of flights to the west coast. Took out almost all of the native cabin noise and drone from the plane. Allows you to listen at an enjoyable level and not have to crank the volume on the source. They fold up nice and compact, and are easy to shove in a bag or carry-on. The in line controller (volume & on/of) is a bit bulky, but it keeps the headphones themselves slimmer and lighter which I appreciate.
Summary: Most noise-cancelling, over-the-ear headphones are far too heavy or too hot for me. On the other hand, I don't like the feeling of earbuds and I know they are not good for your hearing. These headphones combine a better noise-cancelling and higher quality sound than earbuds with a light, comfortable headset that can be easily tucked into my purse without weighing me down or taking up space, for a reasonable price.
