The Sennheiser Momentum ($349)
森海塞尔 Momentum ($349)
There's long been frustration amongst Headphiles with getting good quality sound from sealed headphones. It's hard to make a good sounding headphone with the rear of the driver pumping sound into a small, sealed chamber. Historically, the good sounding sealed cans really didn't seal all that well (Denon AH-DX000 for example). Earlier this year, when Denon discontinued its D-X000 line, a collective groan was heard from the headphone faithful: there simply weren't any other good choices. When Denon's replacement cans arrived another groan was heard. The new cans weren't anywhere near as good as the previous line. Headphonedom had the sad.
一直以来，封闭式耳机就很难获得上佳的音质表现。声音从那么一个狭小封闭的空间里挤出来...想好也难。实际上，从历史上来看，声音比较好的封闭式耳机，往往都是“封闭性”比较差的一类（比如Denon AH-DX000）。今年早些时候，但 Denon宣布停产D-X000系列，整个Hifi界哀声一片——原因很简单，市场上没有更好的选择。当Denon向市场交出D-X000的代替品时，Hifi界再次受伤了——新的产品线的音质，根本不能和D-X000系列相提并论，甚至连接近都谈不上。烧友很受伤。。。
Recently, the pendulum has begun to swing. First Logitech UE released the UE4000, UE6000, and UE9000 series of sealed headphones. All of which sound pretty darned good for the money. (As long as they were used in passive modes---the noise canceling features of the 6000 and 9000 are pretty bass heavy.) Then V-Moda released the M-100, which was a rocking good sealed headphone...for bassheads. But your average, ordinary, everyday headphone geek was still a bit bummed. The Logitech UEs didn't have quite the resolving power of high-end cans, and the M-100, while fun as hell, don't have the fidelity audiophiles desire for acoustic music.
而最近一段时间，钟摆终于动了起来，情况开始发生变化。最开始，罗技发布了UE4000, UE6000, and UE9000。这些耳机在他们各自的价位上，都有着极佳的声音表现（当然，这个结论基于他们的被动模式；主动防噪模式下，UE6000和9000重音被过度强化了）。紧接着，Vmoda发布了M-100，一个十分摇滚，十分拉轰，十分好听的封闭式耳机。。。对低音爱好者而言。但是对于你们这些普通耳机发烧青年来说，情况仍然不容乐观。对于高端耳机而言，UE的新产品缺乏足够的解析度；而M-100虽然很tm带劲，但对于轻口一点的音乐却显得不解风情，也不适合用于严肃听音。
Well...take heart! The new Sennheiser Momentum is a strike right down the middle, and does a lot more right than just delivering good sound. This is the headphone many have been waiting for.
Simple is so good...when it's done well. A simple headband arch with ear capsule that slide on the arms has been done many times. But never so tastefully, in my opinion, and never quite so comfortably. These are very elegant and understated looking cans, very adult.
The headband itself is a thin but sturdy brushed stainless steel arch with a slightly warm tint. A handsome real leather pad/cover is sewn over the top of the arch, which includes a modest but appropriate pad. Small metal name badges ("Sennheiser" on one side, "Momentum" on the other) are affixed to the ends of the leather headband with four flathead Torx screws, which securely capture the wire that goes between the top of the two earpieces and within the leather pad.
The capsules are a made of high quality, glass fiber filled plastic, and are a lovely semi-gloss deep bronze color. The earpads are also leather. The overall impression is warm and brown, a perfect match for whiskey and cigars. Again, very adult.
I've got a couple of gripes though. While I enjoy the brown color scheme, I think the brown of the carry case is pretty gross. I'd like to see a second color option in black and grey. Pulling off a good looking product in shades of brown is quite a trick---and I think Sennheiser has done so here---but I think a black, gray, and silver version would really pop.
I also think the ear capsules are just a tad boring, and would benefit from a bit of stainless steel trim to resonate with the headband. However, being a critic allows me to make comments like this without any real effect. I'd bet Sennheiser had something like that on the drawing board at some point, but axed it in order to make the $349 price point---and if that was so, I think I'd have to agree with them. These are very good looking cans, my comments notwithstanding.
Theoretically, lighter headphones should be more comfortable, but in practice it's not quite so easy. As headphones become lighter they tend to become less durable, and will have fewer moving parts that allow for adjustments and swivels that aid in providing a good fit. Many very lightweight headphones tend to be uncomfortable due to poor fit, or may move too easily around on your head giving a poor sense of security while moving vigorously.
The Momentum is very lightweight (177grams (w/o cable) vs. 293 for UE6000, 232 for Sony MDR-1R, 284 for V-Moda M-100, 334 for Denon AH-D5000), and Sennheiser appears to have made some very subtle and important design decisions that result in a very comfortable wearing experience...for many, but not all. By most any measure, the Momentum is a small headphone, which is good because it keeps the weight down, but not so good if you've got big ears. My head is slightly larger than average size (23.5" vs. 22.5" for the average male head), but my ears are just slightly smaller than average, which is 65mm from top to bottom. The inside dimensions of the Momentum earpads are 50mm X 35mm. That means there's 15mm of something that's got to give. Fortunately, while the outside of the ear cushions are leather, the inside circumference if the ear cushion is made of a very stretchy fine mesh knit fabric covering the soft memory foam that does provide quite a bit of give to accommodate the ear within the cushion. For me it was cozy, but very, very comfortable. But I have heard from many others online that claim the pads simply do not accommodate their ears, and who returned the Momentum due to poor fit.
Momentum的重量就非常轻（仅重177克。相比而言：293 for UE6000， 232 for Sony MDR-1R, 284 for V-Moda M-100, 334 for Denon AH-D5000）并且，森海的工程师尝试了一些非常巧妙而且重要的设计创新，最终使得轻量的Momentum获得了非常牛逼的佩戴舒适度。。。呃。。。对大部分人而言。为什么这么说呢？首先，无论从哪个角度而言，Momentum都是一副很小的耳机。这对于控制它的重量而言，当然是一件好事，但是对于耳朵较大的同志，这就是一个悲剧。我的脑袋比普通人稍大，但是我的耳朵偏小，从上到下长65mm。而Momentum耳机垫内部的尺寸为50mm X 35mm，这意味着有15mm的耳朵会支在外面。但是谢天谢地，Momentum的耳机垫的外部全部为柔软的真*羊皮，内衬为质地舒适的布料，内部材料是同样柔软舒适的记忆海绵。这样一来，我的耳朵边缘部分虽然会和耳机垫发生接触，但是我感觉非常，非常舒适。当然，我也在网上听到了一些关于Momentum耳机垫尺寸的抱怨，一些人甚至因为此退掉了它。
For reference, inside dimensions of UE6000 60mm X 37mm; Sony MDR-1R 59mm X 40mm; V-Moda M-100 57mm X 35mm; Denon AH-D5000 64mm X 42mm. Here's the weird thing, though, the Momentums didn't feel that much smaller than the others due to the very soft internal mesh of the earpad.
在这里做个比较，就耳机垫内部尺寸而言： UE6000 60mm X 37mm; Sony MDR-1R 59mm X 40mm; V-Moda M-100 57mm X 35mm; Denon AH-D5000 64mm X 42mm。可以看出他们都比Momentum大了一圈，但是奇怪的是，我觉得Momentum带在耳朵上的感觉并没有小那么多，这也许是因为它耳机垫所采用的非常轻柔的材料所致。
The other comfort issue I had was that it seemed like the top of the earpads clamped against my head with a bit more force than the bottom of the earpads. I found, after quite a bit of experimentation, that I was simply adjusting the earpieces too high on the headband. I was used to feeling a little more pressure on the top of my head from wearing heavier headphones, which lead me to misadjust the ear pieces slightly. Sennheiser wisely chose a continuous friction adjustment as opposed to one with detents. I found that when I adjusted the earpieces slightly too low it felt like the ear cushions were hanging on my ears, but the excessive clamping force at the top went away. When I adjusted the ear pieces in between these two positions everything fell into place nicely. The measure between too high and too low is a matter of just a millimeter or two. Care in making this adjustment spot on is rewarded with a very comfortable fit.
To summarize: the Momentum is a very light and comfortable headphone, but they must be adjusted carefully, and your ears can't be too much larger than average size (70mm top to bottom is probably the max size ear for these headphones).
Features and Accessories
The Momentum comes with two cables. The iDevice compatible cable is 4.5" long and includes a handsome metal 3-button remote and a very cool adjustable angle 1/8" plug for insertion into your player or phone. I'm a big fan of V-Modas 45 degree angle plug, but I think the Momentum's plug edges it out as the coolest I've seen. A very nice touch.
The plain cable is about four inches longer then the iDevice cable and is terminated in a straight 1/8" connector with a body slender enough to reach through cover cases on smartphones and pads. Personally, if headphones are going to come with a second cable, I prefer that cable to be substantially longer than the one for use with mobile devices. An eight foot cable in the home or office provides much better mobility around the desk or kitchen while listening. Both cables attach to the headphones with a smaller 2.5 mm plug that includes a molded locking feature to secure it to the headphones.
Both cables are fairly thin and pliable, and resist cable-born noise. I've heard many Headphiles complain about thin pliable cables like this, preferring a heftier cable. I think this is a misguided opinion. Just because a cable is thin doesn't mean it's going to sound poor, and for today's use with portable devices of all kinds, a thin flexible cable is going to get in your way much less and have much less cable-born noise than a thicker, stiffer cable. A 1/8" to 1/4" adapter is also included.
A hard sided carry case is included. While the Momentum is a small headphone, it doesn't have any folding features that allow it to get smaller or thinner for storage and transport. The case for them is therefore fairly large...quite a bit larger than the carry cases for other headphones in this category. It's also, to my eyes, a rather unseemly milk chocolate brown color, having little redeeming design value in terms of it's bulbous shape. On the other hand, it appears to be quite sturdily built with dual zippers, each having nice pulls attached. The interior is covered in medium brown velour shaped nicely to accommodate the headphones, and will allow you to store the headphones without having to remove the cable---a rare feature these days. There is also a cable well with a cover that Velcros into place.
After thinking about it for a while, I've begun to think a somewhat ugly carry case might be a good thing. It may be somewhat less attractive to those that might pilfer your beloved headphones...and believe me, after hearing these headphones for any period of time, they will be beloved.
Yeah, let's talk about that, turn the page for sound quality evaluation.
Man, oh man, oh man, these headphones sound really good! Right about here a whole lot of people will expect me to say something like "these sound really good for a sealed headphone" or "these sound really good but aren't quite audiophile grade." Well, I'm not going to do it. These sound really good...no, really, really good, period. Okay, they don't have open airy highs like a well amped HD 600 or HD 800, but the bass on the Momentum is substantially better, and the treble, though not airy and open, is neither veiled nor shrill. And, okay, the bass is not as tight and deep as the Audeze LCD-2, but the soundstage is wider. Any serious headphone audiophile will be happy to rattle off the things that are wrong with just about any "Audiophile" headphone out there, and at some point we have to admit that being an audiophile headphone is just as much about not doing anything wrong as it is about doing particular things very right. And that's the thing about the Momentums, while they do everything very, very well, they do nothing stupendously great. I do think these are audiophile headphones, though, because I'm an audiophile and I love the music the Momentums deliver.
春哥哟，汉子哟，元芳哟，这个耳机听起来灰常，灰常，灰常棒。我想，到了这个地步，很多人都在等着我搬出这样的句子“作为一个封闭式耳机而言，它的音质很牛逼”或者“他们听起来很牛逼，但并没有到发烧的级别”。。。呃。。。我今天不打算用这样的句子。我想说的是“这个耳机就是听起来灰常牛逼，不，是灰常，灰常，灰常牛逼”句号。好吧，我承认，她的高音或许并没有像良好驱动下的HD 600 或HD 800 那般空灵，但是低音却显著比他的两个开放式兄弟强，而他的高音虽然不是那么通透与开阔，但也绝对不浑浊或者刺耳；她的低音或许没有LCD-2之流那般有力紧致，但是她的声场更加开阔。Any serious headphone audiophile will be happy to rattle off the things that are wrong with just about any "Audiophile" headphone out there（译者按：该句不好理解，求指导），而且，在某种程度上，我们必须承认一个所谓的“发烧级别”的高端耳机，更在乎的是“在各方面都不犯错”而并非“在某方面尤为突出”。而这恰恰就是Momentum的特点所在。她在各方面都做得尽善尽美，同时在单项表现上并不突出。我毫无犹豫地认为Momentum是一个“发烧”级别的耳机，我自己是一个忠实的发烧友，而我非常享受Momentum给我带来的音乐。
Generally speaking, I'd characterize the Momentum as a slightly warm sounding headphone, which lacks that last bit of clarity and openness one can find in an open-backed headphone. The bass is full-bodied, punchy, and well extended, but does lack that last bit of tightness that can be heard on planar magnetic headphones. I would not call this a bass accentuated headphone and find the bass to mids balance excellent.
The midrange is wonderfully well behaved, clearly representing the characteristic timbre of acoustic instruments and the human voice. The upper mid-range to treble transition in the presence region can be problematic with headphones, and the Momentums handle this area quite well, deftly delivering harmonic overtones, the throatiness of vocals, and the breathiness of reeds in well proportioned measure. When compared to a headphone like the HD 600, the Momentum does give just a hint of sealed headphone congestion relative to an open design.
The treble response is slightly laid back but very responsive. Cymbal hits and brushwork on drums is clean and fairly natural sounding, though I do detect a hint of something slightly artificial in the treble---just a tad of glare or splashiness in the sound. I don't want to overstate this however, I hate harsh and piercing treble and I would not characterize the Momentum as having these problems in the least. I very much like the overall treble balance of these cans.
Left to right imaging is quite good but image depth is a bit shallow. The dynamics and punch of the Momentum is quite good, nicely balancing both big dynamic hits and resolving the subtle textures of the music.
从左至右的声场非常不错，而垂直的声场相对比较狭小。Momentum的动态与瞬态都非常不错，在大动态的气场与歌曲细微处的演绎之间取得了很好的平衡 （译者注：在我的评测中，对这一点我用Damien rice的i remember 进行了详细说明，Momentum的确很出色）。
Bottom line: while I've heard headphones that do some things better, I'm not sure I've ever heard a headphone that does so much so well.
Isolation and Portability
The Momentum isolates from outside noise quite well and will serve city commuters reasonably well in loud environments. With about 22 Ohms impedance and very good efficiency, these headphones will play very well from portable devices.
Let me get my one gripe out of the way, these cans are slightly small for circumaural headphones, and folks with larger than average ears may want to test fit a pair before committing to a purchase. Aside from that...
The Momentum is simply one of the best balanced headphone offerings I've ever experienced. They're very good looking, very good sounding, have excellent isolation, are easily driven from portable players, and are supremely comfortable. This is an ideal headphone for home, office, and listening on the move, but its sound is so good that I'll happily recommend it to audio professionals and audiophiles for all but the most demanding applications.
The Sennheiser Momentum is going up on the "Wall of Fame" as the best sealed headphone for general purpose uses.
