Sennheiser Momentum On Ear (Blue)


I found the headphone a little tight at first, but if you bend the metal headband a bit and loosen things up, it helps with the comfort level and I liked the microfiber cover on the earcups. I wouldn't call these the most comfortable on-ear headphones...

The Sennheiser Momentum On-Ear is a very good sounding on-ear headphone that has a eye-catching modern retro design, is well-built, and comes with a nice carrying case and a second headphone cable with an Apple-friendly integrated remote and microphone...

Headphones are fairly compact but don't fold up or fold flat; may not be quite comfortable enough for some users.

The Sennheiser Momentum On-Ear may not fully match the larger Momentum's excellent sonics, but it gets you 80 percent of the way there.

Sennheiser Momentum On-Ear


The comfortable Sennheiser Momentum On-Ear headphones deliver a boosted-bass response that manages to not overwhelm the overall balance of the mix.

Distortion-free, quality audio performance with plenty of rich low-end. Very secure, comfortable on-ear design. Includes two detachable cables, one with remote control and microphone for iOS devices

Sound signature is a bit bass heavy. No adapter accessories for headphone jacks

A typical pair of headphones from Sennheiser will focus on rich, but measured, bass response and crisp highs—and the visual design may look more utilitarian than luxurious. So, it's interesting to watch the company add a little bit of variety to its...

Sennheiser Momentum on-ear review


Nobody could accuse Sennheiser of jumping on the headphone bandwagon. The company has been neck-deep in the game since long before it was fashionable, and you'll find models plucked from its massive armory almost everywhere, from professional studios...

Clear, accurate sound signature ; Warm, rich bass ; Superb instrumental spacing ; Ergonomic minimalist design

On the pricey side for an on-ear

Like a great band, sometimes a pair of headphones hits all the right notes; and that’s the Momentum.

Sennheiser MOMENTUM Black headphones Review


Earlier this year we got our first look at Sennheiser's MOMENTUM at CES, a lovely stark looking set of headphones made of metal and leather. Here in the summer of this year we've had our look and listen to the set, and right at the dawn of the...

The set are ringing in at $349.95 for the black edition we’re experiencing here, straight from Sennheiser. There’s a brown edition as well, and as mentioned above, there’s an on-ear edition of the phones headed to market soon too, in lovely tones for...

Sennheiser Momentum Review


In an era where celebrity-themed headphones and mobile devices reign supreme, Sennheiser has had to figure out where it fits in. As a company already in audiophiles' good books, there is an opportunity to show they can play the style and substance game...

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

Not foldable ; A little pricey

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.

Sennheiser Momentum Over-the-Ear Headphones


Sennheiser will always hold a special part of my heart as the HD580 my first audiophile headphone. I can still remember the soft velvety fabric of the earpads and the revelation that was quality music playback. Since then, I have experienced the sound...

Sennheiser Momentum Headphones


The Sennheiser Momentum headphones deliver big, balanced audio in a lightweight premium design.

Stylish lightweight frame; Rich and balanced audio; Comfortable fit; Secure lock audio cables

Expensive; In-line media controls are iOS-exclusive

Click to EnlargeThe Sennheiser Momentum headphones are a bright spot in a market becoming saturated with gaudy plastics and overboosted bass. The headphones are appealing both visually and aurally, combining supple leather and stainless steel with...

Sennheiser MM 450-X


The versatile-but-not-flawless Sennheiser MM 450-X is a Bluetooth headphone set that also has active noise cancellation and the ability to be used as a wired pair.

Excellent audio performance with crisp, articulate highs. Supports Bluetooth and active noise cancellation. Lightweight design. Can be used as a wired pair

Noise cancellation emits audible hiss, causes some distortion on deep bass tracks at high volumes when engaged. Quite expensive. Slightly uncomfortable over long listening periods

Sennheiser's MM 450-X ($449.95 direct) is a headphone pair that seemingly does it all. It's wired, it streams wireless Bluetooth audio, and has active noise cancellation circuitry. From an audio standpoint, the MM 450-X offers excellent performance...

Sennheiser Momentum


Sennheiser may have a wide-ranging lineup of headphones, but it's never offered anything like the Momentum before: a high-performance, audiophile-oriented headphone that's been specifically designed for use with phones and other portable music players.

The Sennheiser Momentum headphones are an elegant full-size over-the-ear pair featuring a brushed stainless-steel headband and plush, leather-covered earpads. Sound and build quality are excellent, and the headphones come with a nice carrying case, as...

The Momentum headphones are pricey and don't fold flat for compact storage.

The Sennheiser Momentum headphones may not have enough bass to satisfy every taste, but they are in every other way the best-sounding full-size audiophile headphones we've heard in a long time.

Sennheiser Momentum


We can add another pair to the emerging category of stunning, mobile headphone designs that Bowers & Wilkins and Harman Kardon have helped to define in recent months. But something feels different about the $349.95 (direct) Sennheiser Momentum—it...

Excellent audio performance, with no distortion at top volumes. Beautifully designed and extremely comfortable. Built-in iPhone controls and mic. Removable cable. Extra, iPhone controls-free cable is included

Quite expensive. Frame is lightweight, but a bit bulkier than most pairs intended to be used portably. Large case

A victory of design and audio performance, the Sennheiser Momentum stands out in an increasingly crowded field of luxury headphones.
