The Mee M6 Pro are a more durable and better-built upgrade to the M6. They come with two cables and the transparent casing on the earbuds and the in-line remote makes them look and feel more premium. They're stable enough to exercise with, and thanks to their decently isolating and portable design they're an adequate choice for commuting. Unfortunately, they tend to sound a bit sharp and they won't be ideal for very noisy environments.
The Mee Audio M6 Pro are a decently versatile in-ears. They're better built than the M6 and deliver a moderately well-balanced audio response but may sound a bit too sharp for some critical listeners. They're easy to carry around on your person with a stable and durable design that would be decent for sports. Unfortunately their lack of controls, mediocre isolation and the below-average sound they may not be the ideal headphones for more critical listeners.
Decent for neutral listening. The M6 Pro have a moderately well balanced audio reproduction but may sound a bit too sharp for some. They also do not have a spacious soundstage due to their closed in-ear design. They won't be the ideal headphones for more neutral listeners but they should sound decent enough for most casual listening.
Above-average for commuting and traveling. They're comfortable and easy to carry around with you at all times. However, they isolate a little less than the M6 and some of the other in-ear headphones we've reviewed. On the upside, you can always mask some of the noise by playing your music a little louder since they do not leak much.
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. Unfortunately, their controls can be a bit difficult to see due to the transparent casing and they may get tangled or hooked on something when exercising.
Decent for office use. They barely leak even at very high volumes so they're a decent pair of headphones to use at the office. They block enough noise for most office environments but won't be the most isolating in-ears that we've tested.
Average for gaming. They have practically no latency since they're wired. Unfortunately, they do not have the best microphone for gaming and have no active features or customisation options which are typically some of the reasons to get a gaming headset.
The MEE M6 Pro look somewhat similar to the regular M6 but with a detachable cable and transparent casing for the earbuds. This makes them stand out and look more premium than their price would suggest. They also have an ear-hook design with angled earbuds that better fit the contours of your ears. The Pro cable is also a bit thicker and more rubberized than the M6.
The Mee audio M6 Pro are slightly more comfortable than the M6 thanks to the additional memory foam tips. Their ear hook design is also less flimsy than on the original M6 which makes them fit your ears a bit more securely. However, they do not quite fit as snugly as some of the pricier in-ear headphones we've reviewed like the Westone W40. Also if you're not a fan of the in-ear fit, they may still get a bit fatiguing after wearing them for a while.
These headphones have a simple and easy-to-use control scheme that's a bit difficult to see due to the transparent casing of the in-line remote. They provide the basic functions for call/music track skipping and volume control. The buttons are also relatively responsive although the slider could use a more discrete input with notches.
The Mee audio M6 Pro like most in-ears are easy to carry around on your person. They will fit into most pockets and come with a good case that's a little large but still quite portable. This makes them practical and convenient to have on you at all times.
Comes with a decent soft case that will protect the headphones from drops and impacts but adds quite a bit of bulk.
The Mee M6 Pro feel a lot more premium than the M6. They have an additional cable in the box with no in-line controls. The cables are decently thick and the earbuds are dense yet lightweight enough that they won't get damaged by a few accidental drops. The ear hook on both cables feel a bit more rigid than on the M6 but they are still a bit flimsy when compared to more sports-oriented headphones. The cables though improved, do not feel as premium as those of more expensive headphones like the Shure SE425 or the Westone W40.
The Mee M6 Pro have a decently stable design. The ear hooks prevent them from easily falling from your ears, but the lack of stiffness means they won't be as stable as more sports-oriented in-ears like the Q9A or the Powerbeats. On the upside, they're still great headphones to run with and will rarely fall out of your ears unless the cable gets hooked or tangled on something.
Very good frequency response consistency. Like other in-ear headphones, if the user is able to achieve a proper fit, then they should be able to get consistent results each time.
Excellent bass range performance. Low frequency is extended down to 22Hz, which is excellent. Low-bass is also well reproduced and shows only 2dB of underemphasis compared to our target. Conversely, high-bass is over our target by about 1.5dB, adding slight boominess to the sound.
Very good mid-range performance. The overall response is pretty consistent, but the 4dB dip centered around 700Hz pushes vocals/leads slightly to the back of the mix.
Mediocre treble range performance. Low-treble is overemphasized by more than 5dB, bringing excess brightness to vocals and lead instruments. The 10dB peak at 5KHz could make the treble to sound harsh on certain tracks.
Average isolation. Unlike the X2 and the BeatsX, the Mee M6 Pro deson't isolate in the bass range, and they even show some resonance buildup around 200Hz. In the mid-range, they achieve about 13dB of isolation which is above-average. In the treble range they reduce ambient noise by more than 36dB, which is good.
Very good leakage performance. The significant portion of leakage sits between 4KHz and 6Khz, which is quite a narrow range and typical of most in-ears. The overall level of leakage is also low, and the leakage will consist of mostly S and T sounds.
Average microphone performance. Speech recorded with the microphone of the Mee Audio M6 PRO sounds full and easily understandable, but will be rather boomy and muffled. They don't fare well in noisy environments, and also won't be able to separate speech from ambient noise in relatively loud environments like a busy street.
Good recording quality. LFE is at 20Hz, but high-frequency extension basically cuts off at 5KHz. Additionally, there is a big bump in the bass range. This results in a recorded speech that sounds full, but boomy in the bass and rather airless and muffled in the higher frequencies.
Sub-par noise handling. The microphone of the M6 achieved a speech-to-noise ratio of 10dB, meaning they are not good at separating speech from ambient noise.
No compatible features.
The Shure SE215 are better critical listening in-ears than the MEE Audio M6 PRO. They are noticeably better-built and also feel more comfortable for long listening sessions. Additionally, their isolation performance is great and will allow you to concentrate on your audio content. Sound-wise, they’ll be boomier than the M6, but won’t be as sharp. On the other hand, the M6 PRO have an in-line remote and an in-line microphone, which the SE215 are lacking. However, our M6 unit seemed to have a mismatch in phase.
