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

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

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

While $300 is a lot to spend, you get a lot for it. Among true wireless earbuds, it's tough to top the sound quality, controls, and fit of the Sennheiser Momentum True Wireless.

Great sound quality; Solid connection

Price; No foam tips; Isolation

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

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

Headphones, headphones, headphones. There are so many of them, and they all sound totally different. If you're planning on buying headphones, then this must surely be the worst bit - deciding which set to get.

Sound lovely; good balanced mid-range; powerful bass; never too much treble; comfortable

Expensive; won't suit audiophiles

In-ear headphones are capable of awesome sound, but you might not be aware of that if you're used to hearing music through the cheap sets included with your smartphone. Even a slight step-up in headphone quality can nab you a set that can achieve ideal sound isolation from the outside world.

Sennheiser has a long, established history of producing quality audio products and its MOMENTUM over-ear headphones are no exception. Wrapped in a stylish, minimalist design, the Sennheiser MOMENTUM headphones boast serious audio and all-day comfort.

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.
