The Beats BeatsX are good headphones for everyday casual use. They have a great wireless range and a well-balanced sound. They're lightweight, portable and unlike other around-the-neck designs, they can be crammed into your pockets without damaging the neckband. They also block enough noise to be versatile for loud environments, but their Apple-centric design may be slightly limiting to Android users.

Pros
  • Portable and stable.
  • Good, passive isolation.
  • Minimal leakage.
Cons
  • The in-ear fit and around-the-neck design are not for everyone.

Beats BeatsX Design Picture

The BeatsX have a unique design that makes them portable and less noticeable as an around-the-neck model. The "Flex Form" neckband is super lightweight, flexible and can easily fit into your pockets. They also have an efficient control scheme, and they're stable enough to work out with or to take to the gym. However, they have the typical in-ear fit, so if you do not find in-ears comfortable then you may have some of the same issues with the BeatsX.

Style
Beats BeatsX Design Picture 2

The BeatsX have a simple around-the-neck style that feels less noticeable than other similarly designed models. The neckband is not much thicker than the flat audio cables, so it seamlessly blends in with the rest of the build quality. This makes them less intrusive once on your neck compared to the QuietComfort 30 or the Level U Pro. The earbuds are also pretty standard but have magnetic covers that stick together which is much better for cable management. They also come in a couple of color schemes to suit your preferences and taste.

The BeatsX have the standard in-ear design that may not be as comfortable for everyone. They have different sized tips to help you find a better fit, but unfortunately, they do not include any foam tips. On the upside, they're super lightweight, and their neckband (flex form) is a lot more flexible than other similar models like the QuietComfort 30 or the Samsung Level u pro. However, this can also be a bit frustrating as the neckband will easily get tangled when you try to put them on.

7.5 Controls

Beats BeatsX Stability Picture

The Beats X are stable headphones to take to the gym and to go running with. They have a wireless design that won't get hooked on anything once you have them on, although the flexible headband can sometimes get tangled when they're not around your neck. They also come with differently sized stability tips (wingtips) to prevent them from falling out of your ears. That and the already stable in-ear tips makes these headphones quite stable for casual and sports use.

Thanks to the unique neckband the BeatsX are a lot more portable than other around-the-neck models. For our measurements, we did not forcibly compress them into a much smaller format but because they're so flexible they fit into the much smaller pouch that is included in the box and could easily fit into most pockets.

Beats BeatsX Build Quality Picture

The build of the Beats X is above-average but not great. They have a nice rubberized design and the flex form cable is flexible enough that the neckband won't get damaged from over-extension. Unlike other similar models. The cables are also rubberized and flat which makes them a bit more durable but they're not as thick as some other models like the Jaybird X3. Also, the inline remote and earbuds feel a bit cheap and plasticky.

Beats BeatsX Frequency Response

The BeatsX are good sounding headphones with excellent and consistent Bass and Mid Range reproduction. They also have very good Imaging and relatively low distortion. However, their Treble lacks a little in detail and clarity and they tend to make vocals and cymbals a bit sharp. Additionally, they don't have the most open and immersive Soundstage, due to their closed-back and in-ear design, which is not ideal for critical listening.

Very good consistency. If the user is able to achieve a proper seal using the assortment of tips that come with the headphones, then they should be able to achieve very consistent results with these headphones every time they use them.

1.5 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.
Good value: >7.5
Noticeable difference: 0.5

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
:
0.0 dB

Poor Soundstage. Due to the in-ear design, these headphones don't interact with the pinna and therefore their Soundstage will be perceived to be located inside the listener's head as opposed to in front. Also, the closed-back design means that these headphones isolate the listener from their environment, creating a closed-up and small Soundstage.

8.4 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.

The BeatsX have surprisingly good isolation despite only passively blocking ambient noise. Their in-ear fit prevents a lot of noise from seeping into your audio so they're a good option to use while commuting or traveling. The seal they create, once in your ears, also barely leaks any sound even at louder volumes. That combined with their good noise isolation make them versatile headphones to use in both loud environments and quieter settings without distracting those around you.

Active Features

Show Help
What it is: Headphones with active components that require a battery. This includes noise cancelling and wireless headphones that actively reduce noise or transmit audio via a wireless connection.
When it matters: How suitable the power and wireless specifications of an active headphone will be, depending on your listening habits. The range and/or discharge time of the active headphone you select will be important if you're often on the move or have long uninterrupted listening sessions.
Score components:

The BeatsX have a great wireless range and decent battery life but lack a good companion app to truly stand out. They have a reliable connection that's remarkable both indoors (when obstructed) and outdoors (in direct line of sight) as well as a competent battery performance that charges quickly. Unfortunately, they have a bit of latency when watching videos and no true app support except for the W1 chip, which gives a few features on Apple devices.

The Beats X have an excellent wireless range especially considering their compact format. In direct line of sight, you will rarely get any connection drops up to 200 ft, and when the Bluetooth source was placed in another room and obstructed by walls, they still managed to maintain a steady and reliable connection up to 40 ft. Unfortunately, they do not have any built-in low latency codecs to help reduce the lag when watching videos or gaming on your non-Apple devices.

3.1 Latency

The BeatsX have an efficient quick charge mode (Fast Fuel) that gives you a lot of listening time for a relatively short charge. In just 5 minutes they give you above 1.2 hours' worth of continuous playback depending on the volume level. They also fully charge in 40-45 minutes. However, at full charge, they only delivered about 6.5 hours of continuous playtime which should be enough for casual use but if you're a power user who has long listening sessions then they may not be ideal especially if you do not have a lightning cable or access to power source. They're good enough for a casual day's use but they won't be the best headphones to take on a long weekend if you're not able to charge them frequently.

Like some of the other recent Beats headphones, the BeatsX makes use of the W1 chip for better integration into the iOS platform. This gives them a simple popup when connecting to an Apple device that displays battery information and a persistent notification that also provides the details about battery life. However, this is not really a functional app as you don't have any equalizers, room effects or additional features.

7.5Mixed 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.
Score components:
The BeatsX are well-rounded headphones that you can use on your daily commute or at the office. They barely leak and isolate well against ambient noise while still delivering a balanced enough sound for both casual and critical listener. Although more critical listeners may prefer the Soundstage and ambiance of bigger or open back headphones.
7.0Critical 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:
Above-average for critical listening. They have a decently balanced audio reproduction that delivers an excellent Bass and good Mid-Range. However, they tend to lack a bit of detail and they may have some sharp spikes when reproducing certain tracks due to inconsistencies in the treble range. Furthermore, because they are in-ear and closed back headphones they have a poor Soundstage and won't have the ambiance of using a good speaker set up or open back headphones.
7.6Commute/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.
Good for commuting. They block a lot of noise passively, and they're easy to carry on you at all times. They also have a decent build quality, but their battery life is slightly short for long road trips.
7.9Sports/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.
Great for sports. They're portable and flexible enough to fit into your pockets. They also have a good wireless design with an efficient control scheme. That plus the around-the-neck fit and the stability tips makes them a good option for working out or running with as they will rarely fall out of your ears.
7.8Office
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.
Score components:
Great for office use. They barely leak even at higher volumes so they will rarely distract your colleagues. They also block a lot of noise passively so they're a good option for lively office environments.
Mediocre-at-best for home theater use. They have a lot of latency which is not ideal for watching videos they're also not as comfortable to wear for long listening sessions. On the upside, they have a good wireless range and the latency is not as bad when used with iOS devices.
