Excerpt: The Sennheiser’s PXC 250 NoiseGards, work well in noise-cancelling mode to block low-frequency background noise. I’ve tried them on in many settings, ranging from routine workouts at the gym, to rock concert performances.
Excellent for traveling,more portable than over-the-ear
10 January 2012
Summary: If you don't want to wear big over-the-ear cans for traveling but want good noise reduction and portability, these are well worth the money.
Pros: Portability,small size and collapsable for easy stowage. Great noise cancelling.Many times I just put them on, without any music, to quiet the gate area while waiting to board. Excellent sound quality. Kevlar strands reinforce the cord.
Cons: The cord where it meets the plug connection, the outer insulation wears out.
Summary: I am a software developer and listen to music all day to keep the surrounding noises down and to concentrate better. Sound, comfort, portability were priority. Even with the On the Ear features, it doesn't just as well as Over the ear egg styles.
Summary: These are an excellent value for the price, compared to other noise cancelling headphones. There are trade-offs, however. These block out less noise than over the ear versions but are more comfortable.
Summary: I did a lot of research before purchasing noise canceling headphones for myself. I wanted them mainly for my long oversees fligths, but also for use at home while working on my computer. I am glad I chose Sennheiser PXC250.
Summary: Great little product. I must say that I'm a big fan on sennheiser: those are actually my 4th pair. I've got some wireless a very cheap vintage pair and a pretty good 490. I just bought those, and it's the first time I had such a good feeling right after buying a pair of cans.
Summary: I bought these headphones at the international airport in Copenhagen to be able to use my iPod on a flight without having to increase the volume to compensate for the noise in the plane. I was quite impressed with the effect of the noise-cancelling.
Summary: This is my first noise-cancelling headset. While I do agree that it reduces ambient noises of certain frequencies (the jet-engine hum and hiss in the aircraft, primarily) it does this by adding a small amount of its own white noise which is definitely audible in quieter environments.
