The MEE Audio M9B are super affordable wireless in-ears with a mediocre and bass-heavy sound. They have a lightweight, portable design, and they're stable enough to take to the gym. Unfortunately, they don't have the best wireless range, and although they isolate decently well, they won't be the best headphones for very noisy commutes. Their in-line control module is also surprisingly bulky.
- Portable and stable design for sports.
- Very low leakage.
- Poor battery life and active features.
- Mediocre, bass-heavy sound.
The MEE audio M9B have a straightforward wireless in-ear design. They're lightweight and will easily fit into most pockets. They're also decently stable enough to run with, and since the earbuds are quite small, they're not as intrusive as some of the other in-ear headphones we've tested. However, they do not come with many tip options, which would have helped with their stability and overall comfort level. Their build quality also feels a bit cheaply made.
The Mee Audio M9B have a straightforward design and simple aesthetic that will work for most. The earbuds are a lot smaller than typical in-ear headphones, making them look somewhat like the Jaybird Freedom. Unfortunately, the in-line remote is considerably larger on the M9B and looks cheaply made. That and thin audio cables further emphasize the budget aspect of the headphones.
The Mee M9B are super lightweight in-ear headphones with a decently comfortable fit. The earbuds are small enough to not touch the outer parts of your ear canal which makes them a bit less fatiguing to wear for long listening sessions compared to typical in-ear headphones. Unfortunately, they do not come with as many tip options as some of the other in-ears we've tested which could have improved their comfort level overall.
The Mee M9B headphones have a basic three button set up that's efficient and well spaced out but doesn't have the best feedback. They provide track-skipping, call/music and volume controls. They're easy-to-use but their in-line remote is surprisingly large and cheaply made which in parts causes the poor button feedback.
The Mee audio M9B are decently stable headphones. They're lightweight, wireless and don't move much once in your ears. Unfortunately, they do not come with any additional stability or foam tip options, which makes them a bit less stable than other similarly designed in-ear headphones. They should be okay to take to the gym, but the earbuds will occasionally slip out of your ears during more intensive exercises.
The Mee M9B are super portable headphones. Their earbuds are smaller than typical in-ears but the in-line remote is a lot larger than most even for a wireless design. On the upside, they're still easy to carry on you at all times since they will easily fit into most pockets and bags.
The Mee Audio M9B are decently built but feel a bit cheap. The earbuds are lightweight and made of a tough plastic that won't easily break even after multiple drops. Unfortunately, the in-line remote feels a bit plasticky and the audio cables are thin and not as rubberized as more premium in-ears. The audio cable is also not removable so while they're decently durable they won't last as long as some of the more high-end in-ears we've reviewed so far.
The Mee audio M9B is a mediocre sounding pair of closed-back in-ear headphones. They have a deep, powerful, and consistent bass, but a recessed mid-range and a sibiliant treble. Additionally, they have average imaging, relatively high harmonic distortion, and like most other in-ears, don't have an open and spacious soundstage.
Good bass range performance. Low-frequency extension is at 10Hz, which is excellent. However, low-bass and mid-bass are over our target by 7dB and 2dB respectively. This results in excess thump and rumble in bass, which some my like.
Mediocre mid-range performance. The response is relatively flat, but consistently under our target by about 5dB. This pushes vocals/leads to the back of the mix, and gives more emphasis to bass and treble frequencies.
Average treble range performance. The dip in low-treble is continuation of the recessed mid-range of the M9B. The narrow but large peaks at 6KHz and 10KHz make the sound of these headphones noticeably sibilant and piercing.
Excellent frequency response consistency. Like most other in-ears, if the user is able to achieve an air-tight fit with the M9B, then they should be getting very similar performance each time.
Poor soundstage performance. Due to the closed-back and in-ear design, the M9B doesn't interact with the pinna and won't have a spacious soundstage either.
Average imaging performance. Phase error is minimal and most of it is in the lower frequencies, which won't be audible. However, we measured some phase mismatch between the L/R drivers of our test unit which could skew the stereo image slightly.
Mediocre harmonic distortion performance. The overall amount of harmonic distortion is low, especially in the bass range. However, the sharp peaks at 800Hz and 3KHz could make those frequencies sound harsh brittle.
The Mee M9B block a decent amount of noise but they won't be the ideal headphones to use in loud environments. They will let the rumbling noise of a subway or train seep into your audio. On the upside, they barely leak even at high volumes so you can mask some of the ambient noise by just turning the volume up.
Decent isolation. The M9B achieves 7dB of isolation in the bass range, which is mediocre. But in the mid and treble ranges the M9B reduces outside noise by 16dB and 33dB respectively, both values being good.
Excellent leakage performance. Like most other closed-back in-ears, the M9B doesn't leak in the bass and mid ranges. The significant portion of their leakage is between 2KH and 5KHz. The overall level of leakage is also very quiet.
Mediocre microphone performance. Speech recorded with the microphone of the M9B will sound rather thin and muffled, but will be relatively easy to understand. In noisy environments, the M9B doesn't fare too well as it won't be able to effectively separate speech from ambient noise in moderately loud situations, like a busy street.
Mediocre recording quality. With LFE at 289Hz and HFE at 3.4KHz, speech recorded with the microphone of the M9B sounds rather thin and muffled. However, the region between LFE and HFE is captured well.
- 100% SpNR
Mediocre noise handling. The microphone of the M9B isn't very good at separating speech from ambient noise and achieved a speech-to-noise ratio of 16dB.
The Mee audio M9B have a mediocre wireless range and relatively high latency that won't be suitable for gaming or watching a lot of video content. They have a sub-par battery life with no battery saving features once connected to your Bluetooth device. They also do not come with an app for further customization which is a little disappointing.
The Mee audio M9B have a mediocre wireless range that barely reaches 30ft when the signal is obstructed. They don't have a good line of sight range either and won't be the best wireless option for a home theater set up or if you don't like to carry your Bluetooth device on you. They're also not the easiest to pair and don't benefit from NFC pairing.
The M9b are not suitable for watching movies or gaming due to their relatively high latency.
These headphones have a below-average battery life. They do not last very long on a single charge and take quite long to charge for an in-ear headphone. Also, they don't have an auto-off timer, so if you forget to disconnect or turn them off once paired with your Bluetooth device, they will quickly run out of power.
No compatible app.
