Summary: I have the opportunity to study at work so I needed some noise-cancelling headphones to block out the ambient noise of my coworkers. I work in a conex (container) that is about 7 feet wide and 40 feet long with military grade environmental control units blasting constantly and 2-6 people in the same room as me having conversations and speaking loudly. The majority of the noise from the ECU's is eliminated with the noise-cancellation...as for the conversations..
Pros: Well built, look great, mostly effective with average office noise and even above average noise, comfortable
Cons: Not wireless, no bluetooth, larger size, does not eliminate all noise, turning your head away/toward a sound source may lead to nausea or dizzyness.
Summary: I have a couple issues with these but I haven't given up yet. They are large and bulky and I don't look forward to taking them on a plane. They were also quite expensive. The noise reduction doesn't drown out my neighbor and the rock tumbler he uses for a lawn mower. I've also noticed a bit of ear discomfort after wearing for a long period of time.
Excerpt: If I would be a frequent flyer I might stick with it, but since I was looking for a headphone that produces beautiful and ACCURATE music/sound I went for the Sennheiser HD380 which exactly as this one, but without the noise cancelation. Sennheiser though gives you and gives you serious products, including the one I am reviewing right now here the PXC 450, and they added a few useful buttons to control the voice cancelation.
Pros: A machine, Comfortable, Durable, Good Bass, Good Value, Great Sound
Excerpt: I bought these to replace an old pair of Bose QC 2 that I lost and used them on a recent trip from Cleveland to the west coast and back. They work as adverstised and noise cancelling is as good or better than the Bose. I like over the ear headphones better than on ear ones. What make the PXC 450s stand out is the talk through function which works great, the volume control, and the detachable cord.
Summary: I was very concerned about purchasing this set vs. a Bose. I've wanted a Bose for years, but the mechanical quality issues worried me. I'm very happy with this purchase. I just finished an 14,000 mile international flight and shared them with many people. The reviews were all good, even from Bose owners. The talk through button is excellent and the construction appears to be better than Bose. Being functional if the battery dies is also a very useful.
Summary: I have been using this PXC450 for more than 2-years, which replaced my Bose QC15. As other reviews mentioned, the sound quality of the PXC450 is clearly better than the Bose QC15. You can itentify more sounds in the sound track which you can't hear with the Bose (too heavy on bass). But I found this PXC450 is not as comfortable as the Bose to wear.
Excerpt: These are my very first noise-cancelling headphones and honestly I expected a bit more of this technology. But ok, it works mostly for low buzzin noises, like engine noise while traveling. The sound is very good although a little flat when noise cancelling is on. I love the talk through function. But best of all is the superb quality of sound when noise cancelling is off. The headphones ale also very comfortable.
Pros: Comfortable, Good Value, Great Sound, Stylish
Summary: I would have given these a 5 star rating, but I still feel that I get a better sound response out of my Sennheiser HD280's (which are significantly cheaper but don't have NR technology). The componentry that provides noise reduction seems to attenuate the signal response (manifested as a reduction in volume and clarity). This can be a problem when playing sources with limited power (like cell phones). I get great sound out of my ipod, computers, and home receiver.
Excerpt: These headphones sound wonderful. They are nice and big and will fit over my big ears. The noise-cancelling is good but not great. The sound is terrific. The battery life could stand to be longer, but you can switch to bypass mode which turns off the noise cancelling and does not require any batteries. That is a plus if the battery dies. The talk through function is really handy on flights, because you don't have to remove the headphones to talk to the flight attendant.
Pros: Clear Sound, Talk Through feature, Versatile
