If you have prejudices against closed headphones, Sennheiser's Momentum is a model that can really open your ears. Literally. The most obvious difference between headphones

Full-bodied and engaging sound

Not foldable

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

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

The Momentum In-Ears are peculiar earphones that can sound too bright on some genres, and just right on others, all while serving up robust bass response. If you're looking for a strong bass response, but perhaps something a bit less bright, consider the B&W C5 Series 2 or the Bose Freestyle .

Powerful audio performance with robust bass response and bright highs; Lightweight, elegant design; Excellent carrying case

Can be too bright at times; Only comes with two pairs of eartips

Sennheiser's on- and over-ear Momentum models have been highly praised for successfully combining form and function, bringing Sennheiser audio performance to the style-focused headphone segment.

Lightweight and comfortable design; 3-button Android remote available; plentiful bass and solid overall performance

Midrange is a bit recessed

It's never an easy decision to spend $350 on a set of cans, but if you're going to, you could do a whole lot worse than the Momentum – we see people do it every day.

Clear with solid range; Balanced sound for all genres; Noise isolation works well; Lightweight; Thoughtful and elegant design

Not foldable; A little pricey

The Sennheiser Momentum on-ear headphones are accurate in delivering sound quality but it's not designed for long periods of usage. With a price tag of $230, it failed to live up to my expectations.

+ Accurate sound signature; + Old-fashioned retro design

- Pricey for an on-ear headphone; - Discomforting

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

The Momentum is such a perfect name for this headphone. As Sennheiser's first consumer oriented upper tier headphone it has done just about everything right and I'm sure it is the first of many headphones Sennheiser makes primarily targeted at the mainstream consumer.

The Sennheiser Momentum In-Ears are a fabulous listen to at this price. They're not up to the level of more expensive, multi-driver models – the slightly toned down mids see to that – but if you like your bass full and juicy, you're not going to be disappointed if you choose to splash out.
