MEE audio X6 Plus Design Picture

The Mee X6 Plus are decently comfortable wireless in-ears with an ear-hook design. They're sufficiently stable to run with and their lightweight in-ear fit won't make your ears warm during more intense workouts. Unfortunately, they have a fairly bulky control scheme and their build quality feels a little cheap. They do not feel as durable or as premium as the M6 Pro but on the upside, they're a bit more compact than the X7.

Style
MEE audio X6 Plus Design Picture 2

The Mee audio X6 Plus look a little like the wireless version of the Mee audio M6 with transparent casings for the earbuds. They have an ear-hook design that gives them a more sporty vibe but unfortunately, they feel cheap, their inline remote is a little bulky, and the hooks are not as rigid as the Q9A or Powerbeats 2 Wireless. The X6 won't be as stable as those headphones but on the upside, their relatively low-profile design will work for most.

The Mee X6 Plus are decently comfortable headphones. They have an ear-hook design and the earbuds are slightly angled to better fit the contours of your ears. However, they still have a fairly typical an in-ear fit so if you do not find in-ears comfortable you will have some of the same issues with these headphones.

MEE audio X6 Plus Build Quality Picture

The build quality of the MEE X6 Plus is average-at-best. They're lightweight and durable enough to withstand a couple accidental drops without breaking. However, the audio cable is relatively thin, which won't last as long as some of the rubberized or flat cables from the more premium in-ears. They also do not have a replaceable cable like the M6 Pro edition and their earbuds feel quite a bit cheaper and considerably less sturdy than the X7.

The Mee X6 Plus are stable enough for sports use. The ear hooks provide a bit more stable fit than standard in-ear models. However, the hooks are not as rigid as some of the other similarly designed headphones we've tested. This means they may not be sturdy enough to keep the headphones attached to your ears during higher intensity exercises at the gym.

MEE audio X6 Plus Frequency Response

The Mee audio X6 Plus is a decent sounding pair of closed-back in-ear headphones. They have a deep and extended bass, capable of producing low thumps and kicks. Their mid-range is also very good, but a tad recessed which could push vocals and lead instrument slightly to the back of the mix. Their treble, however, is only average since it's a bit too bright and could even sound harsh on overly bright tracks. Additionally, the mismatch measured between the L/R drivers could have a negative effect on the stereo balance of the X6. Also, like most other in-ear headphones, they don't have a spacious soundstage and the sound may be perceived to be coming from inside the listener's head as opposed to from a speaker in front.

The Mee audio X6 Plus has an excellent bass range performance. Low-frequency extension is at 14Hz, which is excellent. This means that the X6 won't have any problems producing low-end rumble and thumps. Mid-bass and high-bass are virtually flat and within 0.4dB of our target, resulting in a well-balanced reproduction of bass and kick instruments.

The mid-range of the Mee X6 is very good. The only remark here is the slight recess caused by the wide 5dB dip centered around 600Hz. This pushes the vocals and lead instruments slightly to the back of the mix, and gives more emphasis to bass/kick instruments as well as high frequency sounds such as cymbals and sibilances (S and T sounds).

The Mee audio X6 Plus has excellent frequency response consistency. This is, however, dependent on the user being able to achieve a good fit and air-tight seal using a proper sized tip. It should be noted that to reduce the wear and tear on our dummy head, some in-ear headphones have been measured less than five times. This shouldn't affect the test results since in-ears perform very consistently with every re-seat, if proper seal has been achieved.

PRTF Accuracy (Std. Dev.)
Show Help
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°. PRTF is derived by subtracting the frequency response of a headphone measured with a pinna, from its frequency response measured with the pinna removed (similar to a flatbed). The range of this calculation is 1.5KHz-8KHz. 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.

PRTF (Pinna-related transfer function) of a headphone compared to a reference loudspeaker's PRTF at 30°. PRTF is derived by subtracting the frequency response of the headphones measured with a pinna, from its frequency response measured with the pinna removed (similar to a flatbed). 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.

The isolation of the Mee audio X6 is sub-par. Unlike the BeatsX, Jaybird X2, and X3, which provide passive isolation in the bass range, the X6 Plus does not isolate in the bass range, which covers the rumble of plane engines and buses. However, they achieve a decent 13dB of noise isolation in the mid-range which is mostly important for isolating speech. In the treble range, the X6 reduces outside noise by 26dB, which is also decent. Isolation in the treble range is mostly important for cutting high-frequency sounds like the noise of a fan or S and T sounds in speech.

The Mee X6 has a very good leakage performance. They do not leak in the bass or mid ranges, meaning very little bass and kick will leak from the X6, and the voice leakage will also be without body and very thin sounding. The significant portion of the leakage is in the treble range, between 3KHz and 6KHz. This region is occupied mostly by S and T sounds (sibilance) and cymbals. So at higher volumes, people around you may hear sibilances and cymbals leaking out of your headphones.

The mic of the X6 Plus has a sub-par recording quality. The LFE of 277Hz results in a speech that sounds thin and lacking body. The HFE of 2.1KHz means that speech captured with the X6 will lack brightness and air, and will sound muffled. However, since the area between LFE and HFE is captured well, speech recorded with the X6 Plus should be decently intelligible.

5.9 Noise Handling

Conclusion

6.5Mixed 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 Mee X6 Plus are slightly better than average for mixed usage but have a really short battery life. They're stable enough for sports and sufficiently compact to have on you at all times and have a decent sound. Unfortunately, the short battery life will be a deal breaker for most, and they don't block as much noise as most in-ears which makes them less suitable to use in noisy environments or for commuting.
6.9Critical 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:
Average for critical listening. They have a decent audio reproduction with a good balance of bass and midrange but the peaks in the high frequencies will sound a bit piercing, especially with tracks that are already a little bright. They also have closed-back, in-ear buds, which can't create a spacious soundstage. This means they won't be ideal for critical listening but are sufficiently adequate for more casual use.
6.4Commute/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.
Score components:
Average for commuting. They do not block a lot of noise but since they do not leak much you can mask some of the ambient noise by turning the volume up. Also, they easily fit into most pockets and they're fairly easy to use.
7.6Sports/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.
Score components:
The Mee audio X6 are good headphones for sports. They have a stable ear-hook design, they're breathable, wireless and compact enough to carry around on your person wherever you go. However, they won't be as comfortable for everyone since they have a pretty typical in-ear fit.
6.4Office
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:
Decent for office use. They barely leak even at high volumes much but won't block the ambient noise of a loud office.
5.3Home Theater
