Sennheiser Momentum In-Ear Design Picture

The Momentum In-Ear feel high-end and durable but look a bit bland. They have the typical in-ear design and fit, so they may not be comfortable for everyone. Thankfully, the cables are decently rubberized, and the ear bud tips are flexible enough to deliver a stable fit that's good for jogging or running. They're lightweight, super portable, and come with a great case that will prevent them from getting damaged. 

Style
Sennheiser Momentum In-Ear Design Picture 2

The Momentum In-Ear have a stylish red and black color scheme but do not really stand out design-wise, compared to other in-ear headphones. They have relatively small earbuds that do not protrude outwards when in your ears. And the rubberized cables are slightly flat, which gives them a more well-crafted and somewhat premium appeal. However, they still look a bit bland.

The Momentum In-Ear have the typical in-ear fit, which may not be comfortable for everyone. They come with several tip sizes but no foam or special tips to help with a better fit. On the upside, the tip material is quite flexible, and if you're used to in-ear models, these headphones shouldn't feel too different.

7.5 Controls

Call/Music Control : Yes
Volume Control : Yes

The buttons on the in-line remote provide good tactile feedback and are fairly easy to use. They offer call/music, track skipping, and volume control but they're a bit small. However, they're sufficiently well spaced out and shouldn't be too difficult to use in most situations.

7.0 Stability

Sennheiser Momentum In-Ear Stability Picture

These headphones are quite stable. The in-ear fit buries the ear buds relatively deep within the ear canal. The tips are also very flexible, so they fill and conform to the shape of your ear canal pretty well so that they're not easily dislodged during casual listening sessions. They're sufficiently stable to jog with, but the lack of stability tips means a sharp tug on the audio cable will quickly pull the ear buds out of your ears. They're decent for sports but might not be the best under strenuous exercise conditions.

Sennheiser Momentum In-Ear Build Quality Picture

These headphones feel moderately durable. The cables are decently thick and rubberized, and they're slightly flat to prevent them from getting tangled easily. The in-line control module is also well put together and feels relatively dense. However, where the audio cables connect to the ear buds isn't strengthened by any additional rubber to prevent regular wear and tear. They also do not detach from the ear buds like some of the more expensive in-ear models. This means if they're accidentally damaged the cables will not be replaceable.

Score components:
Sennheiser Momentum In-Ear Frequency Response

The Momentum In-Ear sound a bit too bass-heavy and do not cater well to instrumentals and vocals. They have a deep, extended low-end that may please some fans of bass. However, they're poorly balanced, pushing lead instruments, like guitars, to the back of the mix, where they're a bit drowned out by the overpowering low-end. They don't sound too sharp, but the overall audio reproduction is a bit dark and muffled due to the lack of openness and overemphasis on the lower frequencies.

Average Mid Range performance. Low-mid has a slight tilt favoring lower frequencies, adding a bit of boominess to the sound, but the effect will be subtle. The remarkable issue however, is significant tilt in Mid and High-Mid. Overall, there is about 12dB of tilt in the Mid-Range favoring lower frequencies which results in a scooped-out, thin, and nasal sounding Mid-Range.

Poor Treble Range performance. Low-treble is consistently underemphasized by about 9dB, which will have quite a negative effect on the presence, clarity, and detail of vocals/leads. Especially considering that the scooped out region starts from 500Hz and extends up to 6KHz. The rest of the Treble range is decently produced, although hints of sibilance may be present.

1.9 Soundstage
Show Help
What it is: Soundstage qualities are not inherent to the audio content, the headphones have to 'create' them rather than 'reproduce' them. They determine whether the sound is perceived to be coming from inside or in front of the head, how open and spacious the soundstage is, how much the headphones acoustically interact with the environment, and how strong the phantom center is.
When it matters: When an accurately produced, large and spacious soundstage, similar to that of a stereo loudspeaker setup is desired.
PRTF Error
Show Help
What it is: The average amount of deviation in Pinna-Related Transfer Function of the headphones, compared to that of a loudspeaker. Whether the soundstage is perceived to be unnatural, located inside or in front of the head, is dependent on this quality. The more the headphones activate the HRTF resonances of the ear (similar to what loudspeakers do), the more the soundstage will be pulled out from inside the listener's head. This quality affects both stereo and mono content.
When it matters: When a natural, in-the-front soundstage is desired, similar to that of a loudspeaker.
Good value: <5
Noticeable difference: 0.5

Openness
Show Help
What it is: How open the headphones are, and how open and spacious they sound. This quality affects both stereo and mono content. This test differentiates between acoustically and electronically produced crosstalk and only takes the acoustically generated crosstalk into account. This value is the inverse of the Noise Isolation test score.
When it matters: When an open, wide and roomy sound is desired. A value of 10 indicates a fully open headphone, and a value of 0 indicates a fully closed headphone.

Acoustic Space Excitation
Show Help
What it is: How loud the headphones are, and how much they excite their environment acoustically. If the headphones are loud and open enough, the sound leaking from the headphones takes some of the characteristic of its environment (reflections/reverb) before reflecting back into the open headphones and to the listener's ears. This quality affects both stereo and mono content. This value is the inverse of the Leakage test score.
When it matters: When an open, wide and roomy sound is desired.

Correlated Crosstalk
Show Help
What it is: How strong and solid the phantom center is. This is mostly a stereo quality and its effects on mono content are minimal. This test is sensitive to the phase of the crosstalk and whether it is produced acoustically or electronically.
When it matters: When a true reproduction of the stereo image is desired. A value of 0 indicates no crosstalk, or that the existing crosstalk is not correlated enough to affect the phantom center. A negative score means the crosstalk is out of phase with the original signal, resulting in a slightly wider stereo image at the expense of creating a 'hole' at the center of the stereo field. A positive score means the crosstalk is in phase and positively affecting the phantom center.
Good value: >1dB
Noticeable difference: 0.3dB
:
-0.13 dB

Poor Soundstage. Due to the in-ear design, there is no interaction between the headphones and the pinna, hence their low PRTF score. Also, the closed-back and tight fit of these headphones, causes them to not sound as open as some other in-ears/earbuds. Resulting in a Soundstage that is not as immersive, and may be perceived to be located inside the listener's head.

8.9 Imaging
Show Help
What it is: Imaging qualities are inherent to the audio content, the headphones have to 'reproduce' them rather than 'create' them. They determine how accurately the objects are positioned in the stereo image, and how transparent the imaging is.

Decent isolation. Althought these in-ears isolate only passively, their tight fit creates an impressive degree of isolation for a passive device. In Bass, about 6dB of isolation is achieved which is in the upper limit of what passive headphones can do.

6.4Mixed Usage
Show Help
What it is This is the combination of the different use cases to evaluate how versatile the headphones are. Therefore an everyday headphone should be well-rounded enough to adapt to most situations and environments without significant losses in sound quality, design ergonomics or isolation.
The Sennheiser Momentum In-Ear are decent mixed usage headphones. They do well in loud environments for passive headphones, they're easy to carry around on your person and come with a great case. They also feel durable enough to last a relatively long time. Unfortunately their poorly balanced, bass-heavy sound might be a deal breaker for some.
5.9Critical Listening
Show Help
What it is The level of audio fidelity a headphone can reproduce. Therefore a balanced and true representation of bass, mids, treble, soundstage and imaging, as well as a comfortable listening experience, is essential for critical listening.
Score components:
Subpar for critical listening. The small and closed-back in-ear design means they won't have the most spacious soundstage. That combined with their poorly balanced sound that favors a deep bass over instruments and vocals makes them ill-suited for pure critical listening.
6.0Commute/Travel
Show Help
What it is How well the headphones handle the loud environments involved in commuting or traveling. Therefore your listening experience should be comfortable, hassle-free and as isolated from noise as possible.
Decent for commuting. They're lightweight, ultra portable headphones that passively block a lot of noise. They won't be the best in very loud environments but they can handle the level of noise of a busy commute.
6.7Sports/Fitness
Show Help
What it is How well-adapted the headphones are, to use while doing sports or strenuous exercise. Therefore the headphones should not be too cumbersome and deliver a stable and comfortable listening experience.
Above-average for sports use. They have a stable in-ear fit, which won't easily fall out of your ears when running or jogging. They're also easy to carry around on your person or in your bag.
6.3Office
Show Help
What it is How well the headphones can deliver a comfortable and isolated listening experience in an office-like environment. They should not leak much and should block the noise of a busy office.
Average for office use. They prevent a fair bit of noise from entering your audio. They also barely leak so they won't distract your colleagues in quieter environments.
7.2Studio Recording
Show Help
What it is How effective the headphones are in a studio recording environment. Therefore sound quality should be good, and leakage should be minimal, to not add noise to the recording. They should also be durable for continuous and repeated studio use.
Good for studio use. They barely have any audible leakage, which is great in a recording environment. They also feel decently durable. Unfortunately, their sound is not the best and the in-ear fit is not always comfortable for prolonged studio use.
