The Mixcder E9 Wireless are good budget headphones that perform well. They have a good overall audio reproduction, and their ANC system is quite decent as well. They have a long enough battery life for a full day, and their design is quite comfortable to wear for hours. However, they do feel a bit plasticky, though they aren’t as cheap as some other headphones in their price range. They have a great and easy-to-use control scheme and have surprisingly low latency for Bluetooth headphones.

Our Verdict

7.0 Mixed Usage

The Mixcder E9 are satisfactory for mixed usage. They have a good audio reproduction that will suit most music genres. They also have a decent isolation performance, which is good for commuting and at the office. They might not be the best sports option due to their size and lack of breathability, but on the upside, they can perform quite well regardless of the use you make out of them. Their wireless design might not be ideal for watching video content or gaming, but their latency is low for Bluetooth headphones, so people might not notice the delay.

Pros
  • Good audio reproduction.
  • Decent isolation performance.
  • Low latency for Bluetooth headphones.
  • Comfortable design.
Cons
  • Slightly plasticky build, not the most durable.
  • Old Bluetooth version.
  • Bulky design.
7.3 Neutral Sound

The Mixcder E9 are decent for neutral sound. These headphones have a good frequency response and are versatile for many music genres but will be better suited for bass-heavy music. Their bass is well-balanced and accurate, and the mid-range is flat and follows our target curve well. However, there’s a bit of unevenness in the treble range which affects the brightness and detail of vocals and leads, but this won’t be heard the same way by everyone. They're comfortable and will be a good option if you want good sound quality while on the go.

7.4 Commute/Travel

The Mixcder E9 are decent for commuting. These headphones are comfortable for long rides, and their ANC is decent for blocking out ambient noise. They’re good at reducing the noise from a bus or plane engine, which is great for your daily commute to work or long flights. The long battery life should be more than enough for the longest trips as well.

7.1 Sports/Fitness

The Mixcder E9 are decent for sports. They're a bit bulky, and over-ears usually aren't recommended for sports due to their size and lack of breathability. You will sweat more than usual when training with these, which can be bothersome. You’ll have to carry them around your neck or slide them into a bag if you want to bring them to the gym. On the upside, they're comfortable, and their controls are easy to use.

7.1 Office

The Mixcder E9 are satisfactory for the office. They have decent noise isolation, and you should be able to drown out most of the ambient noise like ambient chatter with these headphones. They're also quite comfortable to wear for a work shift, and their battery should last you a few days. They also don’t leak too much but be sure not to blast your music at a very high volume if there’s not a lot of noise in your environment.

Style

The Mixcder E9 have a sleek style, thanks to the metal-looking cup design. These over-ears are fairly bland otherwise since they only come in black. The cups are rather large as well. They're bulky but, on the upside, the padding is thick and comfortable.

The Mixcder E9 are comfortable headphones that you can wear for a while. They aren’t too heavy, and the padding of the cups is good and comfortable. The headband design resembles the Bose QuietComfort 35 II/QC35 II Wireless 2018 and is nicely padded. The cups could be slightly deeper but should be large enough for most ear shapes and sizes. The headphones are a bit bulky but don’t clamp too much, and the cups have a good range of motion, which is great.

These headphones have a decent control scheme. The physical buttons are large and clicky, making them easy to use. You can also use the power button to play/pause your music and take calls as well. You can easily raise or turn down your volume, and there's an audio cue when reaching maximum or minimum volume. Holding the volume buttons will skip tracks forward and backward. However, you need to be quick if you want to go to the previous tracks, as it might just restart your song instead. The power button could also be in a better position. On the left cup, you also have a dedicated ANC switch that's independent of your power, so be sure to turn it off after powering off the headphones.

Breathability
Avg.Temp.Difference 5.9 °C

Like most over-ears, the Mixcder E9 aren't the most breathable option. Due to their design, they trap heat inside the ear cups and will likely make you sweat more than usual when working out. These are not the best option for sports, but you shouldn’t have any issues for casual listening.

The Mixcder E9 are quite bulky over-ears, but thankfully, you can fold them in a more portable design, which is easier to carry around. Their cups also swivel to lay flat, making it easier to slide into a bag or hang them around your neck. They also come with a nice hard case for when you’re on the move.

The Mixcder E9 come with a nice hard case. It's a bit thin and feels cheaper than some other models, but feels durable. It provides the headphones decent protection against scratches, drops, and water.

Build Quality

The Mixcder E9's build quality is decent. The hinges are good and don’t feel like they’ll break, and the headband is reinforced by a thin metal plate. However, the overall build is a bit plasticky, and the ear cups are covered in cheap-feeling faux leather material.

Design
Stability

The Mixcder E9 are decently stable but won’t be the best option for sports. They stay on the head fairly well, but enough head movement can make them fall easily. You shouldn't use them for running, but thanks to their wireless design, they get rid of the risk of getting a cable stuck or hooked on something and yanking the headphones off your head.

The Mixcder E9's frequency response consistency is very good. Like some other similar noise cancelling headphones, their ANC system seems to help with bass consistency. Some people with glasses might have a drop in bass, though, especially if there’s a break in the seal.

The Mixcder E9 have a very good mid-range performance. The response is well-balanced throughout the range. It results in an accurate reproduction of vocals and lead instruments. However, there’s a small overemphasis in the low-mid, which can clutter vocals and leads a bit, though this won’t be very audible. There’s also a dip in high-mid, which negatively affects the intensity and projection of instruments.

The Mixcder E9's treble performance is sub-par. The response is quite uneven. Some frequencies are under our curve, while others show a small overemphasis. Overall, the treble lacks detail and brightness, especially in the low-treble.

The Mixcder E9's stereo imaging is excellent. Their weighted group delay is very low, which is good. The group delay graph also shows that the entire response is below the audibility threshold. This ensures a tight bass and a transparent treble reproduction. Also, the L/R drivers of our unit were well-matched in frequency, amplitude, and phase response. This is important for the accurate placement and localization of objects (voices, instruments, video game effects) in the stereo image. Note that these results are only valid for our unit, and yours may perform differently.

The Mixcder E9's soundstage is disappointing. The graph shows a good amount of pinna interaction and a decent level of accuracy. There’s also a decent PRTF distance, which results in a wide soundstage. However, due to the closed-back design of these over-ears, the soundstage won’t feel very natural and will be situated inside the listener’s head rather than in front.

The Mixcder E9's noise isolation performance is good. It does a good job against bass frequencies, where the rumble of engines sit, making them a viable option for commuting and traveling. They also do a decent job against ambient chatter, which can be helpful in an office setting. Against high frequencies like S and T sounds and the noise coming from an A/C system, they do a pretty good job at blocking out noise.

The Mixcder E9's leakage performance is decent. The leakage sounds fuller and more comprehensible than that of in-ears and earbuds. However, the overall level of leakage is not too loud. This shouldn’t be an issue in most situations unless you blast music in a very quiet environment.

The recording quality of the Mixcder E9’s integrated mic is mediocre. The recorded/transmitted speech sounds thin, noticeably muffled, and lacking in detail. This won’t be the best option for phone calls.

The Mixcder E9 has about 18 hours of battery life with ANC on, which is good, but slightly disappointing as it's below the 24 advertised hours of continuous playback. With ANC off, the manufacturer mentions a 30-hour battery life. They also take about 3 hours to charge, which is slightly longer than most headphones but shouldn’t be an issue if you just charge your headphones at night. You can also use them while they're charging or wired when they're completely dead, which is very useful.

The Mixcder E9 are Bluetooth-compatible, but they're on the older 4.0 version. They don't support multi-device or NFC pairing, which is disappointing, and their latency is fairly high on all devices. If you want a pair of similarly-performing headphones that also support aptX-LL for a low latency connection, check out the TREBLAB Z2 Wireless.

Differences Between Sizes And Variants

The Mixcder E9 come in one color variant: 'Black'. The manufacturer has also released an upgraded version of these headphones that now supports Bluetooth 5.0 instead of Bluetooth 4.0.

If you come across another variant of these headphones, please let us know in the discussions, and we'll update our review.

Compared To Other Headphones

Comparison picture

The Mixcder E9 are quite decent budget ANC over-ear headphones, which set themselves apart by their good audio reproduction. They also have a pretty decent isolation performance when compared to similar budget models.

See our recommendations for the best noise cancelling headphones, the best noise cancelling headphones under $200, and the best noise cancelling headphones under $100.

Anker Soundcore Life Q20 Wireless

The Mixcder E9 Wireless and the Anker Soundcore Life Q20 Wireless are both decent wireless over-ear headphones with ANC. The Mixcder come with a much nicer carrying case, have a more consistent frequency response among different users, lower latency on Android or PC, and a much better-balanced sound profile. On the other hand, the Anker have better microphone performance, lower iOS latency, and a significantly longer battery.

Cowin E7 Wireless

The Mixcder E9 Wireless are better headphones than the Cowin E7 Wireless. They are noticeably more comfortable, better built, and they offer a superior sound quality. The controls are also better, and the overall noise attenuation of the Mixcder is better than the Cowin. They also come with a nice hard case that protects the headphones better than the Cowin’s pouch. On the other hand, the Cowin offer more battery life and have NFC pairing, but that’s about it.

Mpow EM12 Wireless Earphone Bluetooth Headset

The Mixcder E9 Wireless and the Mpow EM12 Wireless Earphone Bluetooth Headset are for different uses. The Mixcder are wireless over-ear headphones for listening to music, while the Mpow is a mono Bluetooth headset for phone calls. The Mixcder also have a microphone built-in, which allows you to easily take phone calls, and their over-ear design is quite a bit more comfortable. Their battery lasts a lot longer, and they have ANC to give you peace on the bus or in the office. Overall, the Mixcder are a better choice if you're looking for a versatile pair of over-ears for regular use, but if you want something small and discrete just for phone calls, you might be happier with the Mpow.

TREBLAB Z2 Wireless

The Mixcder E9 Wireless are marginally better headphones than the TREBLAB Z2 Wireless. The Mixcder are more comfortable, have a better mic, and have much better ANC. On the other hand, the TREBLAB have a better-balanced sound profile, support multi-device pairing, and last a tiny bit longer off a single charge.

Mpow H10 Wireless

The Mixcder E9 Wireless is a slightly better sounding option than the Mpow H10 Wireless and is also better built. The Mixcder feel better made than the cracking Mpow and the controls are easier to use. On the other hand, the Mpow have a slightly better ANC performance and they offer a bit more battery life.

Anker SoundCore Life 2 Wireless

The Mixcder E9 Wireless and Anker Soundcore Life 2 Wireless are two decent budget headphones. The Mixcder are a better option when you want a balanced and neutral sound, but the Anker will be better for fans of bass. Isolation-wise, the Mixcder have a slight upper hand, especially in the bass range isolation, which is good for commuting. On the other hand, the Anker have a better continuous battery life and an in-line microphone, which the Mixcder lacks.

TaoTronics TT-BH060 Wireless

The Mixcder E9 Wireless are better headphones than the TaoTronics TT-BH060 Wireless. The Mixcder's sound quality is better, and our TaoTronics unit had a noticeable mismatch. The audio reproduction of the Mixcder is, therefore, more balanced and accurate. However, the TaoTronics are Bluetooth 5.0, their noise isolation performance is better, and they offer more battery life. However, they do have higher latency than the impressive Mixcder.
