The Shure SE315 are well-built headphones with a comfortable and stable fit. They're easy to carry around in your pocket, and they're decent headphones for sports since they won't easily fall out of your ears. Unfortunately, their sound quality is disappointing and may be a deal breaker for most listeners, especially in their price range.

The SE315 have a simple ear-hook design that's stable enough for sports. They're more comfortable than typical in-ears thanks to the shape of the ear buds and the wide variety of tips they offer. Although, they're a bit bulkier than most in-ears they're still quite portable and come with a good case that will easily fit into your pockets. The audio cable is thick, durable and replaceable if it ever gets damaged which adds to their durability. Unfortunately, they don't provide a second cable in the box which would have been ideal and they also have no control scheme.
The Shure SE315 have an ear-hook design and angled earbuds that better fit the contours of your ears. The ear buds look and feel premium and the audio cable is thick and heavily rubberized. Like the SE425 they have a transparent variation that stands out a bit more than the all black color scheme.

Comfort
What it is:
Adjustability and degrees of freedom, pressure, stiffness and weight.
When it matters:
When the headphones are going to be used for long durations.
Score components:

Score distribution:
Clamping Force
:
0 lbs
What it is:
The force that the headphones exert on your head, once you have them on. This is purely a measurement of the force applied, which does not take into account the earpad's surface area and the resulting pressure you will feel, on or around your ears.
When it matters:
The tighter the headphones, the more force they put on your head. This can get uncomfortable or cause pain and soreness during long listening sessions.
The Shure 315 have an in-ear fit that's comfortable enough to wear for long periods of time. They have a wide variety of differently sized tips, some made of memory foam that better conform to the shape of your ear canal. They're also worn like an ear-hook design, so the earbuds are shaped to fit snugly within the contours of your ears. This makes them more comfortable than typical in-ears, although if you're not a fan of the in-ear fit, they may still get a bit fatiguing after wearing them for a while.
0
Controls
What it is:
The control scheme of the headphones, the number of functions provided, button layout and ergonomics as well as the quality of tactile feedback.

When it matters:
When the headphones are going to be used by multiple users (classes/studios), by children, in tough conditions, on a daily basis, or for exercise.
Score components:
Subjectively assigned
Score distribution:
These headphones have a sturdy design and replaceable parts for added durability. The ear buds are dense and hard to damage even if you accidentally drop them a few times. The cable is thick, rubberized and also detachable so they can be swapped out for another cable or a wireless adapter to make the in-ear buds wireless. Unfortunately, no extra cables are provided out of the box which is somewhat disappointing for their price especially when compared to the Westone W40.
7.5
Stability
What it is:
How the headphones are designed to prevent them from slipping off your ears or falling off your head.
When it matters:
If you plan on using the headphones while doing sports or other physical activities that requires a lot of movement.
Score components:
Subjectively assigned
Score distribution:
The SE 315 are stable, wired in-ear headphones. They have a pseudo ear-hook design that's flexible and not as stiff other ear-hook models. This makes them stable enough to run with, and they won't fall out of your ears unless you physically pull them out or the audio cable gets hook on something. This makes them above-average headphones for working out, but, the flexible hooks are not as stable as some of the true ear-hook designs that we've previously tested.
Sound
What it is:
How accurately the audio is reproduced. The tests are performed with the headphones' most commonly used features enabled (noise-cancelling, wireless, etc.)
Score components:
- 21% Bass
- 20% Mid
- 19% Treble
- 5% Frequency Response Consistency
- 9% Imaging
- 20% Soundstage
- 6% Total Harmonic Distortion
Score distribution:
The SE315 are a poor sounding pair of closed-back in-ears. The have a well-extended Bass that unfortunately sounds boomy, a muddy and honky sounding Mid range, and a Treble that lacks air and detail. They also have a poor Soundstage and a mediocre distortion performance. On the plus side, they image well, and given a good fit can perform quite consistently.
7.5
Bass
What it is:
Frequency Response from 20Hz-250Hz
When it matters:
When the material is heavy on bass frequencies, such as those of kick drums and bass guitar.

0.1dB
High-Bass
:
5.15 dB
What it is:
The average amount of over/under-emphasis in frequency response from 120Hz-250Hz.
When it matters:
Most instruments get their warmth and full-ness from this range. When over-emphasized, mixes tend to get muddy and boomy.
Good value:
+/-3dB
Noticeable difference:
0.1dB
Good Bass Range performance. Low-bass which is responsible for thump and rumble is lacking by about 3dB. Bass has a tilt towards high-bass, which is overemphasized by up to 6dB. This makes the Bass of these headphones noticeably boomy.

Mid-Mid
:
5.38 dB
What it is:
The average amount of over/under-emphasis in frequency response from 500Hz-1KHz.
When it matters:
This range is occupied mostly by upper harmonics. Over-emphasis sounds forward and boxy. Under-emphasis pushes instruments to the back of the mix.
Good value:
+/-3dB
Noticeable difference:
0.1dB
High-Mid
:
9.32 dB
What it is:
The average amount of over/under-emphasis in frequency response from 1KHz-2KHz.
When it matters:
Most instruments, especially vocals, get their intensity and clarity from this range. Over-emphasis sounds honky and harsh, under-emphasis sounds weak and distant.
Good value:
+/-3dB
Noticeable difference:
0.1dB
Poor Mid Range performance. Low-mid and mid are consistently over our target by more than 5dB which makes these headphones muddy and mid-rangy. High-mid is hyped by more than 10dB, pushing the vocals to the front and making them sound honky.
4.7
Treble
What it is:
Frequency Response from 2KHz-20KHz
When it matters:
When the material is heavy on high-range frequencies, such as voice, cymbals, and any other material where brightness, brilliance and airiness is desired.

When a balanced and neutral (reference) treble performance is desired.
Good value:
<4dB
Noticeable difference:
0.1dB
Score distribution:
Low-Treble
:
0.18 dB
What it is:
The average amount of over/under-emphasis in frequency response from 2KHz-5KHz.
When it matters:
Almost all instruments rely on this range for their presence, detail, and articulation. Over-emphasis can sound harsh and painful. Under-emphasis hurts the comprehensibility of vocals and lead instruments.
Good value:
+/-3dB
Noticeable difference:
0.1dB
Mid-Treble
:
-5.2 dB
What it is:
The average amount of over/under emphasis in frequency response from 5KHz-10KHz.
When it matters:
This is the sibilance range. Cymbals, vocals, and lead instruments rely on this range for brightness and presence. Over-emphasis sounds piercing and painful, under-emphasis sounds dull and lispy.
Good value:
+/-3dB
Noticeable difference:
0.1dB
High-Treble
:
-16.85 dB
What it is:
The average amount of over/under-emphasis in frequency response from 10KHz-20KHz.
When it matters:
This range gives brilliance and airiness to the sound. Over-emphasis sounds hissy, under-emphasis sounds closed-up and lifeless.
Good value:
+/-3dB
Noticeable difference:
0.1dB
Poor Treble Range performance. Low-treble is relatively balanced, but the dip around 6KHz hurts the detail and clarity of vocals/leads. High-treble shows more than 15dB of underemphasis, taking the air and brilliance out of the Treble.
Raw Frequency Response
What it is:
The average uncompensated frequency response of the headphone. For in-ears and earbuds, this corresponds to the average of 5 measurements/re-seats on the dummy head (HMS). For over/on-ear headphones, this corresponds to the average of 5 measurements/re-seats on the HMS (Head Measurement System) for the mid and treble ranges, and 5 measurements/re-seats on 5 human subjects for the bass range.
When it matters:
This is for those who want to see the raw and uncompensated frequency response of the headphone. Some of the more advanced users, are able to read and evaluate headphone frequency response in its raw form and without compensation. This will be especially useful to them if they have their own headphone compensation/target curve, which may differ from the compensation curve/target response used by RTINGS.com.
8.7
Frequency Response Consistency
What it is:
The amount of deviation of each frequency response pass, from the average frequency response.
When it matters:
Shows how consistently the headphones perform after re-positioning them.
Score components:
- 100% Avg. Std. Deviation

When it matters:
Shows how consistently the headphones perform after re-positioning them.
Good value:
<0.5
Noticeable difference:
0.1
Score distribution:
Excellent frequency response consistency. If the user is able to achieve a proper seal and fit using the variety of tips that comes with the SE315, then they should be able to achieve consistent performance each time.
9.0
Imaging
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.
When it matters:
When accurate positioning of the objects in the stereo image, and clear and transparent imaging is desired.
Score components:
Score distribution:
Weighted Group Delay
:
0.08
What it is:
The average amount of group delay calculated based on a perceptual weighting filter. Group delay indicates how long it takes for each frequency to reach their maximum amplitude. This is a monaural quality and can be perceived even with one ear.
When it matters:
Headphones with lower group delay have more transparent imaging and a tighter bass. Headphones with higher group delay in the bass range tend to have a wimpy and loose bass, and headphones with higher group delay in the treble range tend to have a less transparent imaging.
Good value:
<0.5
Noticeable difference:

Score distribution:
Weighted Amplitude Mismatch
:
0.24
What it is:
The Left/Right balance of our test unit, that is, the amount of amplitude difference between the left and right drivers. This is not a design test, but a marker for manufacturing tolerance and ergonomics.
When it matters:
When a properly balanced stereo image and low manufacturing tolerance is desired. A poor score indicates a noticeable difference in level between the left and right drivers.
Good value:
<1.5
Noticeable difference:
0.1
Score distribution:
Weighted Frequency Mismatch
:
1.97
What it is:
The amount of difference (Std. Err.) between the frequency response of the left and right drivers of our test unit. This is not a design test, but a marker for manufacturing tolerance and ergonomics.
When it matters:
When an even and stable stereo image, as well as a low manufacturing tolerance, is desired. A poor score indicates there may be 'holes' in the stereo image at certain frequencies.
Good value:

Noticeable difference:
0.1
Score distribution:
Weighted Phase Mismatch
:
3.74
What it is:
The amount of difference (Std. Err.) between the phase response of the left and right drivers of our test unit. This is not a design test, but a marker for manufacturing tolerance and ergonomics.
When it matters:
When an even and stable stereo image, as well as a low manufacturing tolerance is desired. A poor score indicates there may be inaccuracies in the stereo image reproduction at certain frequencies.
Good value:
<16
Noticeable difference:

Score distribution:
1.1
Soundstage
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.
Score components:
- 15% PRTF Accuracy (Std. Dev.)
- 15% PRTF Size (Avg.)
- 30% PRTF Distance
- 20% Openness
- 10% Acoustic Space Excitation
- 10% Correlated Crosstalk
Score distribution:
PRTF Accuracy (Std. Dev.)
:
N/A
What it is:
The standard deviation of the PRTF (Pinna-related transfer function) of the headphones compared to a reference loudspeaker's PRTF at 30°. This quality is monaural and can be perceived even with one ear. This test does not apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters:
An accurate pinna activation is mainly responsible for how natural and speaker-like the soundstage is perceived to be. The less error in the shape of the PRTF, the more natrual and speaker-like the perception of the soundstage will be. High amounts of error may indicate a soundstage that is unnatural or odd.
Good value:
<2.5
Noticeable difference:
0.1
Score distribution:
PRTF Size (Avg.)
:
N/A
What it is:
The average amplitude of the PRTF (Pinna-related transfer function) of the headphones compared to that of a reference loudspeaker's PRTF at 30°. This quality is monaural and can be perceived even with one ear. This test does not apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters:
This value is responsible for the perceived size of the soundstage. The higher the value, the larger the perceived size of the soundstage. However, values above the reference (5.0dB) could result in a soundstage that is perceived as unnatural or odd.
Good value:
>3.7
Noticeable difference:
0.1
Score distribution:
PRTF Distance
:
N/A
What it is:
The depth of the "10KHz notch" of the headphone's PRTF, which is caused by phase cancellations at the concha. This quality is monaural and can be perceived even with one ear. This test does not apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters:
This value is mainly responsible for the perceived distance and elevation of the soundstage. A small distance value may result in a soundstage that is perceived to be located inside the head. Larger values may help pull the soundstage out from inside of the head and bring it to the front.
Good value:
>13
Noticeable difference:

Score distribution:
Openness
:
2.9
What it is:
How open the headphones are, and how open and spacious they sound. This quality is monaural and can be perceived even with one ear. 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, and could be indirectly related the acoustic impedance of the headphones.
When it matters:
When a headphone with a sense of an open, and spacious soundstage is desired. A value of 10 indicates a fully open headphone, and a value of 0 indicates a fully closed headphone.
Good value:
>7.5
Noticeable difference:
0.5
Acoustic Space Excitation
:
0
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 will be affected by the environment (reflections/reverb) before reflecting back into the open headphones and to the listener's ears. This quality is monaural and can be perceived even with one ear. This value is the inverse of the Leakage test score.
When it matters:
Headphones with higher excitation values, similar to openness, tend to have soundstages that are perceived as more open and spacious.
Good value:
>7.5
Noticeable difference:
0.5
Correlated Crosstalk
:
0 dB
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
Score distribution:
6.0
Total Harmonic Distortion
What it is:
The subtle, unwanted frequencies (harmonics) produced alongside the intended frequencies.
When it matters:
When clean and pure sound reproduction is desired, though its effect is not as noticable as frequency response.
Score components:
- 50% Weighted THD @ 90
- 50% Weighted THD @ 100
Score distribution:
Weighted THD @ 90
:
56.171
What it is:
The overall amount of harmonic distortion measured at 90dB SPL. To make the score more perceptually relevant, more weight is given to the higher frequencies.
When it matters:
How pure the sound is at moderate listening levels.
Good value:
<0.100
Noticeable difference:
0.1
Score distribution:
Weighted THD @ 100
:
71.518
What it is:
The overall amount of harmonic distortion measured at 100dB SPL. To make the score more perceptually relevant, more weight is given to the higher frequencies.
When it matters:
How pure the sound is at loud listening levels.
Good value:
<0.300
Noticeable difference:
0.1
Score distribution:
Mediocre Harmonic Distortion performance. The overall level of distortion is elevated in Bass and Mid range, regardless of the level. The Treble range shows less distortion than the Bass and Mid ranges, also regardless of the level, which is good.
Isolation
The SE315 passively a decent amount of ambient noise. They do fairly well in loud environments thanks to the seal they create within your ears, which prevents a lot of noise from entering your audio. They also barely leak so they're a great option to use in quieter settings when you don't want to distract the people around you. They're not as good as noise-cancelling headphones but they provide enough isolation to be above-average commuting headphones.
7.1
Noise Isolation
What it is:
How much outside noise is blocked out by putting the headphones on.
When it matters:
If the headphones are going to be used in a noisy envinronment (airplane, subway, etc.)

Conclusion
SEE PRICE
Amazon.com
The Shure SE 315 are mediocre mixed usage headphones. They have a compact and stable design and isolate fairly well. Unfortunately, they have a poor sound quality for casual and critical listeners and they lack any controls which makes them a bit more difficult to use with mobile devices.
Below-average for critical listeners. They have decent bass but an overemphasized mid range that makes them sound too warm and muddy for most listeners. They also tend to push instruments and vocals to the front of the mix which with their slight lack of clarity makes their boomy sound quality even worse. Unfortunately, they also have a poor soundstage due to their closed back in-ear design which means they won't be the ideal headphones for critical listeners.
Decent for commuting and traveling. They're comfortable and they're easy to carry on you at all times. They also block a fairly decent amount of ambient noise but they have no controls.
Above-average for sports. They have a good ear-hook design that's stable enough to run with and they're decently comfortable for an in-ear design. Unfortunately, they don't have any controls and the audio cable may get tangled or hooked on something when exercising.
Decent for office use. They barely leak so you won't distract your colleagues even at higher volumes. Unfortunately, they have a subpar sound that may disappoint serious listeners.
Above-average for Home Theater. They're more comfortable than typical in-ears so you can wear them for hours. They also have a no latency since they're wired. Unfortunately, they have a mediocre at best sound quality and a short audio cable that won't be ideal to comfortably watch movies from your couch unless you have an extension cord.
