WARNING
LISTENING TO AUDIO AT EXCESSIVE VOLUMES CAN CAUSE PERMANENT HEARING DAMAGE. USE AS LOW A VOL
UME AS POSSIBLE. Over exposure to excessive sound levels can damage your ears resulting in permanent noise-induced
hearing loss (NIHL). Please use the following guidelines established by the Occupational Safety Health Administration (OSHA)
on maximum time exposure to sound pressure levels before hearing damage occurs.
90 dB SPL
at 8 hours
95 dB SPL
at 4 hours
100 dB SPL
at 2 hours
105 dB SPL
at 1 hour
110 dB SPL
at ½ hour
115 dB SPL
at 15 minutes
120 dB SPL
Avoid or damage may occur
WARNING
Do not use when a failure to hear your surroundings could be dangerous, such as while driving, or when biking, walking,
or jogging where traffic is present and accidents could occur.
Keep this product and its accessories out of reach of children. Handling or use by children may pose a risk of death or se
rious injury. Contains small parts and cords that may pose risk of choking or strangulation.
Set the volume level of the audio device to a minimum, and then after connecting the earphones, adjust the volume gradu
ally. Sudden exposure to loud noises could cause hearing damage.
Turn up the volume control only far enough to hear properly.
Ringing in the ears may indicate that the volume level is too high. Try lowering the volume.
If you connect these earphones to an airplane’s sound system, listen at low levels so that loud messages from the pilot do
not cause discomfort.
Have your hearing checked by an audiologist on a regular basis. If you experience wax buildup, discontinue use until a
medical professional has examined your ears.
Failure to use, clean, or maintain earphone sleeves and nozzles according to manufacturer’s instructions may increase
the risk of sleeves detaching from the nozzle and becoming lodged in your ear.
Prior to inserting the earphone, always recheck the sleeve to make sure it is firmly attached to the nozzle.
If a sleeve becomes lodged in your ear, seek skilled medical assistance to remove the sleeve. Damage to the ear may be
caused by non-professionals attempting to remove the sleeve.
Do not attempt to modify this product. Doing so could result in personal injury and/or product failure.
CAUTION
Do not immerse in water, such as while taking a bath or washing your face, otherwise sound deterioration or failures may
result.
Do not use while sleeping as accidents may result.
Use a slow twisting motion to remove the earphones. Never pull on the earphone cord.
Stop using the earphones immediately if they are causing great discomfort, irritation, rash, discharge, or any other uncom
fortable reaction.
If you are currently receiving ear treatment, consult your physician before using this device.
WARNING

①Power / Control Knob
Rotate to adjust volume level. Turn clockwise to turn unit on. Turn counter-clockwise all the way to turn the unit off.
②Status Indicator
Power LED Input Level LED
Red: Low battery. Red: The input level is too high.
Amber: Battery is charging. Amber: Ideal input level.
Green: The amplifier is charged and powered on. Green: The amplifier is receiving audio signal.
Off: The amplifier is off and not connected to power. Off: The amplifier is not receiving signal or the signal is too
low.
③Line Audio Input
3.5 mm stereo input for connecting to analog audio sources
④Earphone Output

⑤DC Input
Connect to a computer, external battery, or AC power source using a USB type A to Micro-B cable to automatically recharge
the battery.
⑥Input Pad Switch
Select 0dB or -10dB. The pad attenuates the analog input signal to prevent clipping from high output audio sources. Enable
the pad when the audio meter indicates clipping. Attenuate the source volume if the signal continues to clip with the -10 dB
pad engaged.
Note: Use a high quality audio source for the optimal listening experience.

connector collar up to safely release the lock on the earphone cable.
Step 2: Connect a sound source to the amplifier.
Plug the audio device into the LINE IN input.
Step 3: Power on the amplifier
To charge the battery while listening to audio, connect the amplifier to a computer, external battery, or AC power source.
Note: Volume should be adjusted only by using the amp volume knob for best performance. Ensure that volume is optimized in your audio source.
Lithium-ion Rechargeable Batteries
Storing Batteries
To avoid degrading battery health, keep the storage temperature range between 10°C to 25°C (50°F to 77°F).
Battery Repair and Replacement
Lithiumion batteries have no “memory effect”, and instead experience a more linear reduction in capacity. Contact Shure Ser
vice and Repair to replace the battery if you experience any issues.

Using Earphones
Choosing a Sleeve
Select an earphone sleeve that provides the best fit and sound isolation. It should be easy to insert, fit comfortably, and easy to
remove.
Soft Flex Sleeves: In small, medium, and large sizes. Made from pliable rubber.
Soft Foam Sleeves: Compress the foam sleeve between your fingers and insert into the ear canal.
Hold in place for about ten seconds while the foam expands.
Triple-Flange Sleeves: If desired, use scissors to trim the stem on the sleeve.
Wearing the Earphones
Carefully insert the earphone into the ear like an earplug, so that a tight seal is formed.
Important: If there is a lack of low frequency response (bass), the earphone sleeve may not be forming a proper seal.
Gently push the earphone deeper into the ear canal or try using a a different sleeve.
Warning: Do not push the earphone sleeve beyond the ear canal opening.
Wear earphone cables over the back of the ear to keep them in place during physical activity. Guide the cable down ei
ther the front or back of the body, and use the cable cinch to tighten up the remaining slack.
The fit of the earphone can greatly affect sound quality.
Changing Sleeves
Twist and pull to remove the sleeve from the nozzle.
Slide on a new sleeve so that it completely covers the barb and the nozzle.

Shure Incorporated

•
Caution: If the barb or any of the nozzle is exposed, the sleeve is not properly installed. Replace sleeves if they do not tightly grip the nozzle. To ensure proper
fit and performance, use only sleeves supplied by Shure (unless using custom molded sleeves).
Removing the Earphones
Grasp the body of earphone and gently twist to remove.
Note: Do not pull on cable to remove earphone.
Maintenance and Cleaning
Careful maintenance ensures a tight seal between the sleeve and nozzle, improving sound quality and product safety.
Keep the earphones and sleeves as clean and dry as possible.

To clean sleeves, remove them from earphones, gently rinse in warm water and air dry. Foam sleeves require a longer
drying time. Inspect for damage and replace if necessary. Ear sleeves must be completely dry before reusing.
Wipe the earphones and sleeves with mild antiseptic to avoid infections. Do not use alcohol-based disinfectants.
Do not expose earphones to extreme temperatures.
Replace sleeves if they do not fit properly.
Do not attempt to modify this product. Doing so will void the warranty and could result in personal injury and/or product
failure.
Cleaning the Earphone Nozzle
If you notice a change in sound quality, remove the sleeve and check the nozzle of your earphone. If nozzle is blocked, clear
obstruction by using wire loop end of cleaning tool.
If no obstruction is found or if sound quality does not improve, replace the sleeve with a new sleeve.
Caution: When cleaning, do not force any object through the earphone nozzle! This will damage the earphone sound filter.
Warning: The cleaning tool is only to be used to clean the earphones. Any other use, such as using the tool to clean ears or foam sleeve, could result in injury.
The cable connectors to the earphones may collect debris or other deposits that can affect audio quality. If this happens, disconnect the cables and clean them
using a dry cotton swab.
