MEElectronics Product Manual for In-Ear Headphones
Online Product Manual for MEElectronics In-Ear Headphones
Earphone Models: SX-31, RX12, R1, N8, N9, M2, M16, M9, M21, M31, M11+, SP51, CW31, A151, A161P
(Discontinued: CC51, CX21, RX11, M11)
Warning Do not use headphones at high volumes for extended periods of time as doing so will result in permanent hearing damage. It is advised you keep volume levels moderate to low at all times for your safety. Please visit for more info. Do not use while driving a car, cycling, operating machinery, or performing other activities that require hearing surrounding sounds.
Safety Tip It is advised to turn the volume on your music player all the way down before connecting your MEElectronics earphones. After the earphones are connected and seated in your ears, gradually increase the volume until you reach a comfortable listening level. Achieving a good seal will isolate you from outside noises allowing you to play your music at lower volume levels.
First Use/
How to Wear
A proper seal between the earpiece and your ear canal is required to deliver the high level of sound quality designed into your MEElectronics earphones. Please follow the steps below to achieve a proper seal.
  1. Select and install the correct ear tips for your ears

    This may require trying multiple sizes/types of ear tips. If you have larger ears, try the larger tips first, if you have smaller ears, try the smaller tips first. Because ear canals are not necessarily symmetric, you may need to use different-size ear tips in each ear. When changing ear tips, make sure they are installed securely before putting the earpiece in your ear.

    Always make sure ear tips are installed completely on the earphone nozzle to avoid an ear tip coming off in your ear. Frequent cleaning of the outer portion of the nozzle and the ear tips, including inside the stalk, will help keep them in place.
    Please see the Care and Storage section for additional information on cleaning your earphones and ear tips.

  2. Insert the ear piece into your ear

    Each earphone is marked with an R for right and L for left. Many MEElectronics earphones can be worn either with the cable down or the cable over the ear. Wearing your earphones with the cable over the ear will allow different insertion angles and depths, reduce/eliminate any cable noise you may experience, and result in a more secure fit.

    Different wear styles.
    not every style will work with every MEElectronics earphone

    When inserting your earphones, move the earpiece around until the ear tip seals in your ear canal. You should not be able to see the ear tip after the earphone has been properly inserted.

    To ease insertion you can pull the upper part of your ear upwards and back while inserting your earphone, which may improve your ability to get a deep insertion at the proper angle. Also, moistening the ear tips with a very small amount of ear lubricant or saliva prior to insertion may make insertion easier. If you feel like you do not have a good seal after you release the earphones, you can gently wiggle the housing a little deeper to achieve a seal.

For Earphones with Memory Wire
(M6, M6P, S6)
  1. Insert the Earpiece

    Straighten the memory wire and insert the earpiece into your ear. Each earphone is marked with a R for right and a L for left channels and are not swappable.

  2. Securing the Memory Wire

    Make sure your earphone is seated correctly in your ear before adjusting the memory wire.

Ear Tips and Fit

The sound quality of an in-ear earphone is highly dependent on the fit, including ear tip size, insertion angle, and insertion depth. Everyone's ears are shaped and sized a little differently and there are many ways you can wear earphones. Spending some time to achieve the best fit will result in maximum musical enjoyment.

Bass response and isolation are most affected by the quality of the seal between ear tip and ear. Please experiment with different sized ear tips to create the best seal. Ear canals are rarely symmetric and it is possible that you may achieve the best results with different sized ear tips in each ear.

Insertion Angle:
The ear canal is naturally angled up, and inserting the earphone at that angle usually results in the best sound. Wearing the earphones with the cable over your ear may ease finding the best angle for you.

Insertion Depth:
Insertion depth will change the characteristics of the sound. Ear tip size is important in achieving a seal at different insertion depths. Larger ear tips typically work better for a shallow insertion while the next size down may work for a deeper insertion. For example, if you use the large tips with a shallow insertion, the earphones may sound better with the medium tips and a deeper insertion.

Aftermarket Eartips Aftermarket eartips are sometimes used to improve the comfort, seal, and sound of in-ear earphones. Comply Foam is a popular manufacturer of aftermarket foam eartips. Please see our Comply Compatibility Chart or visit for more info
Cable Guides Cable guides are included with the A161P and can be purchased separately for other MEElectronics earphones here. Cable guides help keep the cable in place securely when wearing your earphones over the ear. If you are experiencing cable noise or are having issues keeping your earphones in place or achieving a proper seal, wearing your earphones over the ear will help.

Cable Cinch and Shirt Clip

Many MEElectronics earphones are outfitted with a shirt clip and/or cable cinch. Tighten the cable cinch and use the shirt clip to control cable movement during activities.

The cinch can effectively shorten the length of the cable after the Y split for use behind the back or to keep the earphones in place more securely. The cable slider can also be slid toward the earphones to reduce tangling during storage.

The cable comes with an attached shirt clip that can hold it where you want it and keep it from getting in the way during activities.

NOTE: Removing the shirt clip can cause damage to the cable; please use caution when removing the cable clip, if necessary. It is advised to bend the plastic lip of the clip before attempting to remove.

Earphone Removal


Gently wiggle the ear phone before removal to break the seal. Pull the earpiece straight out of your ear; if you are wearing the earphone in an over-the-ear manner, unwrap the cable from over your ears. Place the earphone in a safe place such as in an earphone carrying case.
Care and Storage Removing the cable from your device:

Use a carrying case for storage and to protect your earphones while not in use. For best results, either wrap the cable around 3 fingers before placing in the carrying case, or just bunch the earphone cable up and put in the carrying case.
Cleaning Cleaning your MEElectronics products regularly is hygienic and will help keep the earphones looking their best. Please follow these steps when cleaning your MEElectronics earphones:
  • Gently remove the ear tips from your earphone
  • Take a cotton swab that is either dry or has a small amount of rubbing alcohol or hydrogen peroxide on it (replace with soapy water for wooden earphones)
  • Swab around the nozzle of the earphone, but not the inside of the nozzle
  • Swab the ear tip including the inside of the stalk
  • Ear tips can also be submerged fully in rubbing alcohol or hydrogen peroxide
  • Wait for the earphones and ear tips to dry completely
  • Put the tips back on the earphone, making sure they are fitted securely
Use While Traveling with Altitude Changes (Airplane/Car/Train/etc.) During large, rapid changes in altitude you will experience pressure changes which will affect the way you hear your earphones. It is recommended that you break the seal when you feel increased pressure due to altitude changes to maintain the best sound quality.
Microphone and Remote Functionality (P versions only) The inline microphone will work for hands free phone calls. The remote button will function to answer calls, play/pause audio, and skip tracks when used with certain devices and programs. Please visit our P Version Compatibility page for info.
Burn In Burn in is the process of the driver settling in after manufacture, which will slightly change the sound over time. Burn in is not necessary as the changes will slowly take place during use but is recommended before evaluating the sound quality. Please see the Burn In Section for more info.
Troubleshooting Please see the Troubleshooting Guide.
Warranty MEElectronics earphones purchased from authorized retailers are covered by a manufacturer warranty. For issues with your product please visit our Warranty Information page.
Troubleshooting Guide
Issue Resolution
No sound coming from your headphone Check that the headphone is plugged in all the way, audio is playing, volume is at the appropriate level, and the device has not been muted. Check another known working headphone to verify the issue.
One channel has no sound Check to make sure your headphone plug is inserted all the way in the jack of the connected device. Try rotating the plug to see if lint or dirt in the jack is causing problems. Try a different audio stream or file. Check another known working headphone to verify the issue.
Lack of bass, the sound is quiet, thin, tinny, and/or distant Fit and ear tips play a major role in how you hear your earphones. If the bass on your MEElectronics earphones is missing or seems weak, you have not achieved a good seal with your earphone. If the earphones sound quiet, you are more than likely not inserting them deep enough in your ears.
Please see the Ear Tips and Fit section of the online user manual for info.

For the A151/A161P:
Many other earphone/headphones have an extreme amount of enhanced bass and may make the accurate bass of the MEElectronics Armature Series models sound lacking. Over time your perception of the bass response will change as you get used to the armature sound.

Ear pieces won't stay in your ears Several things can cause the ear piece to come out of your ears including:
  • Incorrect tip size for your ear canal. Try other sizes of ear tips.
  • The earphones not inserted at the best angle for your ears. An over-the-ear wear style and/or deeper insertion may achieve a better insertion angle.
  • The ear tips have a buildup of bodily fluids. Clean the ear tips as described in the Care and Storage section of the online user manual.
Sound Imbalance
(sound is louder in one ear than the other)
There are several possible reasons:
  • The song or source is not balanced; try another song and/or source
  • There is pressure buildup in your ear; release it by pulling back on the earphone housing, pulling the upper part of your ear to release the pressure, or both
  • Your ears require different sized ear tips; swap the channels and see if you still hear an imbalance on the same side (i.e. put the left channel in your right ear and the right channel in your left ear)
  • Your ear tip is not sealing properly; inspect the ear tip for tears and blockages and make sure it is installed properly
(cable noise during movement, aka the stethoscope effect)
Try the following to reduce or minimize microphonics:
  • Wear the cable over your ears (cable guides may be helpful)
  • Attach the shirt clip on the cable to your clothing
  • Tighten the sliding cable cinch under your chin
  • Wear the cables down your back
  • Wear the cables under your clothing
Crinkling Sound
(driver flex)
A crinkling sound when inserting one or both of the driver housings is not unusual and is caused by air pressure in your ear compressing the very thin driver diaphragm. It can even lead to a temporary reduction or loss of sound after insertion. If you experience a reduction or loss of sound in one or both ears, you can pull on your ear lobe to relieve the pressure in your ear or pull the earphone out slightly, which should restore the sound. The crinkling will often diminish with time and use. Different ear tips may also reduce/eliminate the crinkling.
Static Crackling Sounds Static crackling from the earphones, microphone, or both can be caused by static electricity charge. This usually occurs during dry weather and with the use of heating or some air conditioning. If you are experiencing static crackling sounds, it is recommended that you relieve the static buildup or cease use of electronic devices. While damage from static electricity is not likely, it is possible.
Static or Other Noise
When Plug is Moved
If the plug or inside of the jack is not clean you may hear static, clicking, or other noise when the plug is moved. Please clean the plug with a soft cloth or isopropyl alcohol. For information on cleaning the inside of the headphone jack, please consult your phone/media player manufacturer.
The remote button is not working with your device (P version only) Visit our P Version Compatibility page to make sure the remote is compatible
Earphones sound hollow unless the remote button is pressed (P version only) Your device is not pin compatible with the A161P. You may purchase a TRRS adapter to resolve the issue. Please see our P Version Compatibility page for more info.
Random Remote Action
(P version only)

Lint in the jack of your phone can cause a short between the terminals, resulting in random button events. Please check the inside of your jack with a flashlight and consult the manufacturer of your device for the best way to clean the headphone jack.

Moisture, including sweat, can also cause the remote button to short out. Please either allow the unit to air dry or use a hair dryer to dry out the remote.

For other issues, or if the problem persists, please contact customer service at for assistance

Burn In Guide

What is burn in:
What is burn in? Burn in is the idea that diaphragms of dynamic driver headphones may improve their sound over the first several hours of use, with reports of improvements occurring anywhere from 8 hours to 100 hours of burn in.

Do I need to burn in my earphones/headphones:
Burn in is not necessary to enjoy your MEElectronics headphones. However, many people report improvement in sound quality with burn in. Burn in will occur naturally while listening to your headphones, but if you are a critical listener, you may want to accelerate this process by letting music play at a moderate level continuously for anywhere from a day through a week.

What is the best way to burn in my headphones:
While there are many methods of burning in headphones, playing sound through the headphones will result in burn in. There are different types of signals you can play to burn in your headphones, such as pink noise, white noise, and frequency sweeps, or just by playing your music. We recommend using the music you would normally listen to played at a loud level, but not louder than the loudest volume you would listen at.

How long should I burn in my headphones:
Again, burn in is not necessary, but if you do decide to burn in your headphones the typical recommended number of hours is 50.

I have burned in my headphones but don't notice any changes:
If you do not notice a difference after your headphone has burned in, that is OK - even those who do report hearing a change with burn-in agree that the differences can often be very subtle.

Frequently Asked Questions
Q: What is the difference between the P version and the non-P version of your earphones (i.e. M9 vs M9P)?
A: The P versions have an inline remote and microphone while the non-P versions do not. For information on how the remote works, please see the Remote Button Operation Guide .

Q: My earphone treble sounds very sharp and overpowering.
A: This is usually caused by how deep you are inserting your earphone into your ear. If the earphone is not inserted deep enough, or too deep, the overall sound balance can be off as well as the treble sounding too sharp and harsh. Please try different tips and insertion depths/angles.

Q: Some of my music sound harsh and/or distorted with noises I haven't heard before, what is wrong?
A: MEElectronics headphones and earphones present all the details in your music, good or bad. Some songs have poor mastering, or the compressed sound quality is poor, which you will be able to hear on the higher end headphones by MEE. Many other headphones have rolled-off treble, masking poor recording quality. Higher quality masters with higher bit rates will sound best with your MEElectronics products.

Q: I hear hiss with my MEE earphones, but not with my other headphones, what can I do?
A: Hiss is due to the combination of the player and the earphones, and sensitivity to hiss varies from person to person. If a player has hiss, there is little you can do to remedy the situation. Sometimes using an equalizer to lower the treble will help. Using an impedance adapter or in-line volume control may also help.

Q: I want more sound isolation, what can I do?
A: Use longer eartips (e.g. dual flanges vs single flanges) and experiment with insertion depth for maximum sound isolation. Aftermarket foam tips offer additional isolation. Comply foam tips are typically available worldwide and are very comfortable.

Q: My order has shipped but there is no tracking information, how can I track my order? A: Orders in the US offer tracking, however the basic international shipping does not offer any tracking. Orders typically take between 2 to 4 weeks to arrive internationally. However, 6 weeks is not uncommon in some countries. If it has been 4 weeks, please check your local customs office with the customs tracking number. Alternatively, you can choose FedEx shipping which does offer tracking and usually takes less time.

Q: I tried to order from the website, but you don't ship to my country. How do I get your product?
A: MEElectronics ships to most of the world, with the exception of countries where you can buy products online and/or in retail stores. We also do not ship to countries where there is a high rate of products not arriving to the customer.

Q: Compared with my current earphones, my MEE earphones have less volume; are my M6 earphones defective?
A: Sensitivity will vary from earphone to earphone, so you may have to adjust the player volume with to get the same actual volume with your MEElectronics product as a higher-sensitivity earphone. If the volume is not sufficient, please check the fit of the earphone first as this is most likely the problem. Without a deep and airtight seal the volume will be lower.

Q: The bass seems muddy and the sound quality is bad, is my M6 defective?
A: Sound quality is very dependent on the fit and seal. It is also widely accepted that burn in improves the sound quality of dynamic driver in-ear earphones. Fit is dependent on insertion angle, insertion depth, and ear tip seal. Please adjust the fit of your M6 in your ear and try the different tips to achieve the optimal sound. Please look at the M6 product manual for additional information. If you do have a good fit and seal, please contact customer service for further assistance.

Q: Why do you include more ear tips than the competition?
A: Everyone has different ear sizes and shapes and while the usual three sets of tips may fit most people's ears, those tips might not offer the best seal, comfort, and sound quality for the combination of ear/earphone. Different insertion depths will affect the sound quality and balance as well, so offering more tip choices gives more chances for better comfort with a deep insertion and more chances for a better seal with a shallow insertion.
