PROS: The sound from these headphones are amazing! I'd never hear bass without distortion until I tried out these puppies. Great design, construction and very light! I could wear these for hours without much discomfort. CONS: Not worth the price.

Sennheiser has long been a fixture in the professional audio and high-end audiophile market. I've used my Sennheiser HD 595 and HD 600 Open Dynamic headphones for many applications - in the studio for reference monitoring, for sound quality consulting, and for audio forensics.

If you've stepped into an audio store of any kind, or the headphone section of a big box store, you know the name Sennheiser. The first "real" headphones I bought were Sennheisers. I used them until the pleather on the cups cracked and started sticking to my ears (they were on-ears).

Build quality and aesthetics; Sound quality; Angle cable end

Overly large case; Small earcups

While it seems like every week there's a hot new player in the headphone market, there are a few manufacturers who have been there since the beginning, before there even was a Walkman, let alone 128 GB portable media players that double as phones. is one of these headphone pioneers.

Nice performance for the price; Excellent fit and finish; Available in a number of colors; Solid build quality

Not the most comfortable 'phone on my ears; Flimsy (and gaudy red) iPhone-specific cable; Case is a bit small and not too sturdy

I own a pair of Momentum Over-ears and i've always loved them. When i saw this in-ear model coming out I had to get it right away.

The design is great and the is definetly the sennheiser-quality

I waited a bit more depth from the sound but it's great when one gets used to it

As I mentioned earlier in this review, I have tried out and owned a lot of different headphones and earphones over the years. I'm not a full-on audiophile, but I do love good, clean sound. I'd much rather have accurate and well-balanced sound than brain shaking bass. Not that bass is a bad thing.

Package and case are stellar; Super comfortable; Two cables - one for Apple products; one for everything else; Fantastic clarity and overall well-balanced sound; Black leather & red stitching; Stainless steel; Appear and feel quite durable

A bit expensive

These are essentially the smaller versions of the brilliant full-size Momentum headphones. The same design in a smaller form factor means enhanced portability aspect, which the Momentum missed out on. Excellent sound, and built very well.

Classy design and premium finish; Excellent sound quality; across genres; Strong bass; Apple devices get in-line volume control

Uncomfortable over long periods of use; Noise isolation is bad

A bit snug. The point on which reviewers disagree most about these Sennheiser Momentum headphones is how comfortably they fit. Most reviewers find them comfortable and not too heavy. Wired magazine notes that the individual ear cups rotate slightly to "give you a nice seal without too much clamp.

Excellent sound; Great build quality; Stylish design; Good passive noise blocking

Uncomfortable for some users; Cables and connectors may break easily

Great sound for ear buds. Comfortable in my ear and they fit well. Color is nice and the cable seems sturdy. However not ideal buds for when your moving around a lot and walking around often. You can hear the thud noise from the movement of the buds in your ears bouncing around with every step.

The depth and breadth of the sound field produced by these earbuds is incredible -- definitely the best earbuds I've ever tried. The free sennheiser app -- also allows you to customize and fine tune the equalization a bit to your liking. Would agree with other reviewers re: volume.

Comfort and fit Outstanding sound quality Connectivity EQ customization through app

volume control and track selection a bit tricky
