IMPORTANT SAFETY AND OPERATING INSTRUCTIONS.
PLEASE READ BEFORE USING YOUR HEADPHONES.
Before placing headphones over ears, set volume to the lowest level then gradually
increase until desired volume level is reached. • Avoid listening at high volume
levels for long periods of time. Noise levels are measured in decibels (dB). Regular
exposure to noise at or above 85dB can cause hearing loss. Monitor your listen-
ing as hearing loss happens over time. Refer to the guidelines on the Consumer
Electronics Association’s website relating to safe listening levels: http://www.
ce.org/PDF/ListenLifetime_spread.pdf • Do not use headphones at
times when your attention is required—such as driving, operating heavy machin-
ery, bicycling, or jogging. It is dangerous and in many jurisdictions illegal to drive
wearing noise-isolating headphones because it dramatically decreases your chance
of hearing life saving sounds around you such as car horns or emergency sirens.
• This product generates strong permanent magnetic fields that could cause in-

terference with cardiac pacemakers and implanted defibrillators (ICDs). Maintain
a distance of at least 4-inches (10cm) between the headphones and the medical
device. • Do not expose product to heat (hair dryer, radiators, etc.) and do not
store in direct sunlight for extended periods of time. • Protect product from
moisture. • Avoid dropping and strong impact. • Do not pull the cord to
remove the headphones from the ear or from the audio device. • Clean or
replace ear pads prior to use by other persons.

PROPER PLACEMENT
The side with an ‘R’ is for the right ear. The side with an ‘L’ is for the left ear. You
can also use the cable to distinguish between the right and left side. The cable
attaches on the left side.
ADJUSTING THE HEADPHONE SIZE
To adjust the size of the headphones, gently slide each ear cup down and away
from the headband.

CONNECTING AND REMOVING THE CABLE
Attach the cable to the left side of the headphones. When properly attached, the
remote and microphone should be on the side closest to the headphones. To remove
the cable, grip the connector between your fingers and gently pull it away from the
headphones.
COLLAPSING THE HEADPHONES FOR TRAVEL
Gently slide both ear cups up until they are next to the headband. Swivel each ear
cup 90 degrees so the headphones are flat. Place the headphones in the travel case.
REPLACING THE EAR PADS
Gently pinch and pull the old ear pad away from the ear cup. Work the leather edge
on back of the new ear pad into the channel around the perimeter of the ear cup.
It is sized to fit snugly.

MICROPHONE AND REMOTE (NON-APPLE PRODUCTS)
The headphones will play audio from any source with a standard 3.5mm 3-conduc-
tor (stereo headphone) socket. The microphone will function with most smart phones
and similar devices with a standard 3.5mm 4-conductor socket (stereo headphone
+ microphone). The remote control will function with some non-Apple smart
phones, digital media players, and similar devices. Exact functions of the remote
will vary by make and model and MartinLogan cannot guarantee compatibility with
specific brands or models.
BREAK IN
Allow approximately 15–30 hours of break in at moderate listening levels before
any critical listening. Like most high-performance audio reproduction devices, a

break-in period should result in improved performance. For rapid break-in you may
choose to leave the headphones connected to an audio source playing music during
the night or when otherwise not in use.
CLEANING
To clean the headphones lightly wipe the ear piece and cord with a slightly
damp cloth. Never use solvents and other harsh cleaning products as they will
permanently damage the headphones.
