Summary: I currently own Sennheiser HD 555 which sound great but they are open back headphones and don't cut the room noise at all. I was hoping moving up to a better model would have the same or better sound quality but I was really disappointed with these.
Pros: The noise cancelling works pretty well which is why I gave these 2 eggs. The mid and high end sound ok but is tinny.
Cons: After trying these out in multiple devices and listening to different types of classical and rock music I was very disappointed with the low end. It just doesn't exist. I'm not after bounce my brain around type of bass, but you need something there to support the structure of the music and it was...
Summary: I use a diesel tractor to cut lawns and having the head phones to drown out noise while enjoying an audio of my choice rather than hearing the the loud noise of the tractor. I hear a fan noise which is considerably less nosey without.
Pros: The head phones are comfortable even when cutting a field in a hot and humid environment.
Cons: Cost is high but the payback is in meeting and exceeding my expectations.
Summary: the noise reduction system works well. However, that comes at the cost of headphones that fit tight over your ears. On a long flight, after the 2nd movie I watched, my ears and my head were hurting. Not to mention how sweaty your ears get from being completely sealed off from air.
Summary: I love the PXC 450s. I'm partial to Sennheiser sound - and these are no exception. They're marketed as travel headphones and fully deliver on that promise: a sturdy but flexible case that will fit into any bag, good sound on the go, and decent noise reduction.
Pros: Strong build, nice adapters for airplane or studio listening, classic Sennheiser sound.
Cons: Without a headphone amp, sound will be noticeably quieter due to high impedance.
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...
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.
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.
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: 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.
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?
Pros: Hands down best isolation ,best versatility, best sound.
Cons: Bulky. Sorry, you are not cool wearing these things.
Summary: One of the only things I own that still uses crappy, environmentally unfriendly disposable batteries (more on that later). Big, bulky and maxes out at a fairly low volume if you like your music loud (thank you nanny state).
Pros: Sound quality very good.
Cons: Bulky. Sound quality zero when the craptastic old school battery feature goes awry.
