Sennheiser HDC 451

Pros: stylish, comfortable, good sound suppression

Cons: Does not suppress very low frequency, mediocre sound, expensive, difficult to store.

The Bottom Line: If $150 isn't expensive, then this unit is a good product. If $150 is expensive, then this unit is not a good value.

Review: I've used three noise suppression headphones--Koss, Sennheiser, and Recton, and tested at the store about 10. For comfort and style, Sennheiser is tops. For sound suppression and sound quality, Koss is best.

One characteristic I would...

Pros: Very good NC

Cons: Don't sound good in quiet environment; they'll buffet in a breeze

The Bottom Line: Recommend them if you know and understand the noisy environment they're intended to be used in.

Review: I've owned the Noisebuster and the Sony NC headphones, and bought these to replace a B/O Noisebuster.
I needed a pair to hear quiet music while going for a walk on noisy streets. These work adequately for that purpose. For my noisy office (lots of...

Pros: Very comfortable, lightweight. ANR works extremely well.

Cons: "Black Box" could have been designed better.

Review: This is one of those products, that when you read the description, you say to yourself "Yeah, right.",but the first time you flip the switch on these headphones, your eyes will light up like a little kid. The technology behind the active noise...

Pros: they work

Cons: cord rather short

Review: I bought these headphones by accident:
I'd gone into the store to get a decent pair of bud 'phones to use at the
office while programming.
The store was completely out of quality bud 'phones, but they did have
some noise canceling...

Pros: Low cost, good quality sound

Cons: Bad durability, no carrying case

The Bottom Line: I'd recommend these only if you can't pay for a better version. While the sound quality is good, what good does it do if it breaks?

Review: I got the Sennheiser HDC 451 headphones because I travel quite a bit via airplane and was looking for a pair of headphones that would cancel out some of the noise from the plane. The Bose headphones, while second-to-none, were a bit expensive at around ...

Pros: Decent construction, comfortable. Noise reduction in line with competing brand headphones.

Cons: Sound quality is much worse than competing active NR headphones.

The Bottom Line: Way too pricey for mediocre quality sound.

Review: As a one-time frequent coast-to-coast traveller, I invested in several sets of active noise reduction headphones in the quest for the most relaxing trips. When I saw these phones advertised recently, I couldn't resist checking out the Sennheiser entry...

Pros: The best noise canceling

Cons: Bad sound quality, Not loud enough, Bad battery placement,
