Excerpt: Bought these Sennheiser PXC-450's after having trawled through countless flights and used innumerable other headphones. Excellent sound quality ( fyi I have Naim equipment at home and top of the range B&W in the car) and a worthy upgrade from the foldable 250's - I love the talk through feature on the plane and the wire detaches at both ends if needed. Also works without noise reduction (why would you..?) in case of battery running out.
Pros: Comfortable, Durable, Good Bass, Great Sound, Stylish
Excerpt: Not as good as the Bose in noise reduction but has better sound quality. It's nice to finally hear a movie at normal volume without noise on the plane. Talk through and bypass are must-have features.
Excerpt: I don't have much experience with noise canceling headphones, but after quite a bit of research I settled on these (it came down to Bose and Sennheiser). For a casual listener, these are amazing headphones. Their maiden voyage was a flight from Seattle to New York and now I can't imagine taking a trip without them. I can't say much about how the noise canceling compares to other brands, but the difference between having them on and off was night and day.
Excerpt: Difficult to find true audiophile headphones these days. Newer ones tend to cater for gaming to hiphop with boosted levels. Great noise cancelling, no noise leakage and no wireless static. Very happy with purchase!
Summary: Keep in mind I am hearing impaired. These headphones are amazing. The comfort of the ear cushions is unbelievable, I can finally listen for long periods without any discomfort. As for the sound, it's incredible and clear. Noise canceling is superb ( but I am hearing impaired so it is possible I wouldn't hear some outside sounds as it is) Coolness factor? I think they're really cool looking. Then again, I'm 44 so my kind of cool could be outdated.
Pros: Excellent sound quality, durability, and noise cancellation. Comfort.
Cons: I always forget to turn them off when done so I finally got smart and started using rechargeables
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: Just an all around outstanding product and definitely worth the investment if you are a serious music listener. I purchased these to replace a broken pair of another brand headphones that I use on my digital keyboard. I've had the keyboard for many years but hooking it up to these headphones was like getting a whole new keyboard. The sound reproduction is outstanding, providing a clear warm sound.
Summary: My previous headset was a Bose QC 2 and wanted to try a full ear cover noise canceling headset. The Sennheiser PXC 450 received enough good reviews for me to give them a try. Upon receiving them, the first thing that I noticed was a persistent low frequency rumble. And over time it has become more persistent, especially on airplane flights when it seems that it magnifies the low frequency noises (especially landing gear noises, flap extension/retraction).
Excerpt: Sennheiser is 100% on target with the PXC 450 cans! Noise cancel is excellent and the talk thru feature is VERY useful. In use in a noisy workout gym or on the red eye from CA I found these headphones deliver excellent noise cancellation WITH exceptional music reproduction. I tested them with hi res files at 192/24 using a tube based headphone amp and they compare favorably to the top of the line Sennheiser 800s'. I tried two BOSE models..
Pros: Comfortable, Compact, Durable, Good Bass, Good Value, Great Sound, Lightweight
Summary: Let's face. They aren't cool. My coworker says that they make me look like a space alien. At least, I assume she means the headphones. But they are amazing phones. I have tried top of the line Bose and Sony. This one beats them. First of all, the passive pass-through. Battery down? No problem, you still get sound. And what lovely, clear, natural sound. I have found I don't even need the NR on at all, ever (well, on the subway or train). The sound isolation is that good.
Pros: Hands down best isolation ,best versatility, best sound.
Cons: Bulky. Sorry, you are not cool wearing these things.
