Summary: These were unavailable from NCIX when I ordered them, so I actually got them from another source, but thought I'd write a quick review anyway. I buy Sennheiser headphones exclusively because I've never been let down by their sound and build quality. These headphones were worth every penny. The sound when you get them is very flat, as it should be. Not heavy on highs or lows, just flat across the board.
Pros: - sound quality, - noise cancelling, - comfortable for long periods of time, - don't have to listen to screaming neighbour kids anymore, - sennheiser
Excerpt: When your music’s blaring, and suddenly there’s someone who wish to talk to you, there is this button on one side of the headphone which enables you to switch it to “mic” mood. That means you could hear what the person is saying, and won’t go “WHAT??” After that person has finished talking, you could then go back to your music listening by adjusting the volume buttons, which you could also flick to high or low, depending on you.
Summary: Bought these headphone because i have heard them before and also liked the fact that they are noise canceling. The noise canceling works really well on low frequency sounds like plane engines and car noise. Used these just yesterday on a 3 hours car trip with noise canceling on and it creates a sense of space making you feel very comfortable, when i eventually took the headphones off the road noise was deafening because i didn't realize how well they canceled the sound...
Pros: Can be used without batteries when they run out, Great sound quality in bypass mode, Great at noise canceling, Build quality is amazing, Ear cups are SOOO Soft, Detachable Cable
Cons: Not to blown away by the look of them, but some people like them.
Summary: I got these as an early Christmas present and wore them for the first time on a 14 hour flight from Australia to Argentina, the comfort factor was exceptional I never took them off and even slept in them, the noise reduction provided made the flight so much more comfortable.
Pros: Excellent sound quality and good comfortable over the ear fit.
Summary: Every time I flew I used these headphones on the flight to listen to music, watch films etc. to pass the time but never for just 'noise cancelling'. I am really pleased with the quality of sound. However, I recently did a red-eye flight and wanted to sleep, so I unplugged the lead and switched on the headphones and used them for just noise-cancelling and I was amazed at how good they were.
Pros: 1. They work really well., 2. The position of the headband allows you to lay back without knocking them off your ears.
Summary: I bought these recently and have been really disappointed. I don't understand why such an expensive set of a active noise cancelling headphones would have such poor passive cancellation. I ended up just going back to using my Sennheiser HD-280s (passive). I found them to have better sound, noise reduction and no hassle with batteries. I even took the 450's back to the distributor as I thought my set must have been faulty, unfortunately no.
Cons: Hopeless passive cancellation (high frequencies) and the active cancellation (low frequencies) was just okay. in their "neutral state" without the cancelling turned on it can sound a bit like putting your ear up to a sea shell, they really need to have more sound deadening materials in there.
Summary: I bought a set of these used. What a great deal! The Audio quality is so good I began using them on my stero system to listen to analog recordings. I replace a set of Beyr Dynamic headphones. These are more comfortable. If you need the noise canceling capability, it also work superb. No more fan or other background noises. Get a pair and work the pile ups.
Summary: I got these specifically to filter out office noise listening to streams through my computer, as I'm a programmer in a farm of 6x6 cubes (about 25) with a lot of distracting noise. They accomplish that task well, and I am very happy with the sound quality. I specifically wanted an 'around-the-ear' model, and these aren't noticeably heavy at all; I wear them all day.
Pros: Comfortable, Convenient, Easy to use, Good Bass, Great Sound
Summary: I currently have two pairs of Sennheiser headphones in addition to the PXC-450s, one of which is an "on-the-ears" PXC-250 with the noise cancellation feature. I have been impressed with the quality of Sennheiser headphones, overall, and have not strongly considered other brands except Sennheiser and Bose. I was looking for a really good over-the-ears set, and it was between the PXC-450s and the Bose QC-15s. I like some Bose products (i.e.
