The superior sound quality and the comfortable design will allow you to listen effortlessly and quietly.

The lightweight design won't constrict your head; and the ear cups are plush and comfortable

Only 16 hours of battery life is less than other models; which can last up to 50 hours

You will not be disappointed. Great quality, comfortable and nice long cord. Worth the money.

I use it for 2 years, and I'm not tired. Even if it does not offer perhaps the best "noise cancellation" of the market, it outperforms the competition in several ways. In particular, a remarkable musicality (this is a real headphone "audiophile" Sennheiser): no special coloring of the sound, not...

I purchased these to replace an old pair of Sennheiser NR phones I've had for about 15 years. While I liked my old ones these are far better both in design and operation.

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.

- sound quality; - noise cancelling; - comfortable for long periods of time; - don't have to listen to screaming neighbour kids anymore; - sennheiser

- nothing

I have used many NC headphones before (Bose QC, AKG, AT), but these are the most comfortable, best sounding ones yet. A bit big, but it works perfect for my ears.

Crutchfield has collected 30 user reviews for this product with an average rating of 4.6 out of 5 stars. The most recent reviewer said, "I bought these after a long struggle to choose between the Sennheisers and the Bose Quiet Comforts. I chose these based on reviews of comfort and overall sound.

Very comfortable, and the noise cancellation is superb. No distortion even at very high volume. Worth every cent.
