Frequently Asked Questions - MACH 20 Westone

How do I insert the Westone MACH 20 properly?

Gently pull your ear upward and outward, insert the earpiece with a slight twist until comfortable. The cable should loop over your ear and the memory wire should conform to your ear shape.

How do I change the wax filters on my MACH 20?

Remove the eartip, then unscrew the old wax guard using the provided cleaning tool. Screw in a new wax guard and reattach the eartip. Replace filters every few months or when sound becomes muffled.

Can I replace the cable on the MACH 20?

Yes, the cable is detachable via MMXC connectors. To replace, firmly pull the cable straight out from the earpiece and plug in a new compatible cable until it clicks.

What is the sound signature of the MACH 20?

The MACH 20 offers a balanced sound with slightly accentuated mids and clear treble. The dual balanced armature drivers provide detailed vocals and instruments with a tight bass response.

Are the MACH 20 headphones suitable for live monitoring?

Yes, the MACH 20 is designed for professional use with high isolation (-25 dB) and accurate sound reproduction, making it ideal for stage monitoring and critical listening.

How do I clean my Westone MACH 20?

Wipe the earpieces with a soft, dry cloth. Clean the eartips with mild soap and water, then dry completely. Do not use alcohol or abrasive cleaners. Regularly check and replace wax guards.

What should I do if I experience discomfort?

Try different sized eartips from the included set. Ensure the cable is correctly routed over the ear and the memory wire is shaped to your ear. If discomfort persists, consult a hearing professional.

How long do the MACH 20 earphones typically last?

With proper care (avoiding moisture, storing in the monitor vault), the MACH 20 can last several years. Replaceable parts like cables and filters extend their lifespan.

Can I use the MACH 20 with my smartphone?

Yes, the 3.5 mm connector works with most smartphones, tablets, and audio players. For devices without a headphone jack, use a compatible adapter or wireless cable.

Where can I find replacement parts for the MACH 20?

Replacement parts such as cables, eartips, wax guards, and dampers are available through Westone's official website or authorized dealers.

INSERT EARTIP

into ear canal and rotate the monitor backwards & into position

Before inserting the monitor, turn down the volume on your sound source and either drape the cord over your shoulders and down your back, or run the cord down in front. The monitors are marked on the inside face with a red WA logo for the right ear, blue WA logo for the left. If you have selected a foam eartip, compress the foam by rolling it between your fingers (FIG. 1). If using a silicone STAR tip, the instructions are the same except there is no need to compress the tips. With the body of the monitor toward the back of your ear and the cord facing forward, insert the eartip into your ear canal before the foam expands back to its original shape (FIG. 2). If you have trouble inserting the monitor, reach over your head with your opposite hand and gently pull up and back on the top of your ear before inserting the eartip. This helps straighten your ear canal and may allow for easier insertion. The monitor cord should run over and behind your ear. Hold the monitor in place for 5 to 10 seconds to allow the foam to expand and conform to the shape of your ear canal (FIG. 3).

Once the monitors and cords are comfortably in place, slide the cable zipper up to the base of your skull (not too snugly, as this may cause discomfort). This will limit cable movement and help ensure that your monitors stay in place during use.

CARE & MAINTENANCE

Here are a few simple guidelines that can greatly increase your listening enjoyment and the lifespan of your Mach Series monitors:

• Always store your monitors in the provided case.
• In case of poor sound quality due to earwax in the sound bore, use the included wax removal loop to carefully remove the earwax. Never use any other object to attempt to remove the earwax as this may result in damage to the monitors and will void the warranty.
• Do not use the cord to remove the monitors from your ears. This may cause damage to the cord and result in poor performance. Damage of this nature is not covered by the warranty.
• Do not expose your monitors to temperature extremes.
• Avoid strong impacts to your monitors.
• Wipe down your monitors after each use.
• Never immerse your monitors in water.
• You should use extreme caution or temporarily discontinue use in potentially hazardous situations.
• Don't use while operating a motorized vehicle as it may create a traffic hazard & is illegal in many areas.

Please Note: Moisture in your monitors can cause temporary performance issues. Do not insert your monitors if your ears are wet. Always dry your ears completely before inserting your monitors. Should you inadvertently allow water or perspiration into the monitors and they quit working, allow to dry completely before attempting to use again. Minor moisture build-up should dry out and not affect long-term performance. Extended exposure to moisture or submersion will result in permanent damage (not covered by the warranty).

Remember, personal hearing protection is your responsibility!

Please read this important information before using your Westone Audio Mach Series monitors. If everything sounds muffled or you hear ringing or buzzing after using your monitors, your ears are trying to give you a warning! These are symptoms normally associated with a condition known as Temporary Threshold Shift and are an indication of conditions that could lead to permanent hearing loss.

While no two individuals' hearing sensitivity is exactly the same, there are established safety guidelines for sound levels versus time of exposure. The chart (right) is based on OSHA's (Occupational Health and Safety Administration) exposure information for industry. Remember that these guidelines are based on average hearing sensitivity. Your sensitivity may be above or below these levels.

To prevent possible hearing damage, do not listen at high volume levels for long periods.

dB Level	MAXIMUM Exposure Time
85	8hr
90	4hr
95	2hr
100	1hr
105	30mins
110	15mins
