Important safety information
Important safety information
왘 Read this instruction manual carefully and completely before using the
product.
왘 Always include this safety guide when passing the product on to third
parties.
왘 Do not use an obviously defective product.
Preventing damage to health and accidents
왘 Protect your hearing from high volume levels. Permanent
hearing damage may occur when headphones are used at
high volume levels for long periods of time. Sennheiser headphones sound exceptionally good at low and medium volume levels.
왘 Do not use the product in situations which require special attention
(e.g. in traffic or when performing skilled jobs).
왘 Keep the headphones at least 10 cm/3.94” from cardiac pacemakers or
implanted defibrillators. The headphones contain magnets that generate a magnetic field which could cause interference with cardiac pacemakers and implanted defibrillators.
왘 Do not use the product near water and do not expose it to rain or moisture to reduce the risk of fire or electric shock.
왘 Keep the product, accessories and packaging parts out of reach of children and pets to prevent accidents and choking hazards.
왘 Use only power supply units provided by Sennheiser.
Preventing damage to the product and malfunctions
왘 Always keep the product dry and do not expose it to extreme temperatures to avoid corrosion or deformation. The normal operating temperature is from 0 to 40°C/32 to 104°F.
왘 Use the product with care and store it in a clean, dust-free environment.
왘 Do not use the product if it is obviously defective, if it has been dropped
or if liquids or objects have gotten inside the product. In this case, contact a qualified specialist workshop or your Sennheiser service partner
to have the product checked.
왘 Switch the headphones off after use to conserve battery power.
Remove the batteries if the product will not be used for extended periods of time.
왘 Unplug the power supply unit from the AC wall outlet
– to completely disconnect the product from the power source,
– during lightning storms, or
– when unused for long periods of time.
왘 Ensure that the power supply unit is
– in a safe operating condition and easily accessible,
– properly plugged into the AC wall outlet,
– operated only within the permissible temperature range,
– not exposed to direct sunlight for longer periods of time in order to
prevent heat accumulation.
왘 Do not place your headphones on a glass dummy head, chair armrest or
similar objects for long periods as this can widen the headband and
reduce the contact pressure of the headphones.
RS 185 | 3
Important safety information
왘 Varnish or furniture polish may degrade the feet of the transmitter,
which could stain your furniture. You should therefore place the transmitter on a non-slip pad to avoid potential staining of furniture.
왘 Do not operate the product near heat sources.
왘 Clean the product only with a soft, dry cloth.
왘 Use only attachments/accessories/spare parts supplied or recommended by Sennheiser.

Setting up the transmitter
왘 Choose a suitable place near your audio source.
왘 Separate the transmitter and other wireless devices in a room by at
least 50 cm/20” to avoid interference.
왘 Do not place the transmitter close to metal objects such as shelf bars,
reinforced concrete walls, etc. as this can decrease the cover range of
the transmitter.

Putting the RS 185 into operation
Connecting the transmitter to an audio source
You can simultaneously connect 2 different audio sources (e.g. a TV and a
stereo hi-fi system) to the transmitter. The transmitter features a digital
as well as an analog audio input. If you connect 2 audio sources, you can
toggle between them using the AUDIO INPUT SELECTION switch (see
page 23).
You can also refer to the beginner’s video guides on how to connect
your digital wireless headphone system to a TV at
www.sennheiser.com/how-to-videos.
왘 Switch your audio source off before connecting the transmitter.
왘 Check the connection options available for your audio source (audio
output, usually marked “OUT”).
왘 Select the corresponding connection cable and, if necessary, a suitable
adapter.
왘 Depending on the connection option selected, go to the respective
chapter and follow the instructions on how to connect the transmitter
to an audio source.

To achieve the best possible listening experience, we recommended that
you connect your RS 185 headphone system to your home cinema or hi-fi
system using the supplied optical digital cable.
Your wireless headphone system allows digital audio streaming using only
PCM audio output from devices connected through the optical digital input
DIGITAL OPTICAL IN. Refer to the sound menu or the instruction manual of
your device to change from another audio stream (e.g. Bitstream) to PCM.

CAUTION
8.5h
Danger of damage to the headphones!
If you insert non-rechargeable batteries into the battery
compartments, the batteries may leak during charging and
can damage your headphones.
왘 Do not place the headphones on the headphones holder if
you are using non-rechargeable batteries.
In general, a complete charging cycle takes about 8.5 hours. However,
before using the headphones for the first time, charge the rechargeable
batteries for at least 16 hours without interruption to optimize the performance of the batteries.
When the rechargeable batteries are almost empty, the HDR status LED
turns red and you hear beeps in the headphones. The headphones switch
off after few minutes.
왘 Place the headphones on the headphones holder of the transmitter.
You may place the headphones on either side provided that the
charging contacts of the headphones and the transmitter connect.
The headphones automatically switch off and the Charge status LED
on the transmitter lights up red. When the rechargeable batteries are
fully charged, the Charge status LED
turns green.

Adjusting the headband
For good sound quality and best possible wearing comfort, the headband
has to be adjusted to properly fit your head. The headphones feature an
adjustable headband with a snap-in locking mechanism for easy adjustment.
왘 Wear the headphones so that the headband runs over the top of your
head. Observe the L (left) and R (right) markings on the outer headband when putting the headphones on.
왘 Adjust the length of the headband until
– your ears are comfortably covered by the ear pads,
– you feel even, gentle pressure around your ears,
– a snug fit of the headband on the head is ensured.

Danger due to high volume levels
Before putting on the headphones and before toggling between
the level modes, adjust the volume on the headphones to a low
level. Toggling between different modes may cause an enormous
volume jump that can possibly damage your hearing.
Follow these steps to adjust the signal of your analog audio input.
1 Press the LEVEL button on the headphones or on the transmitter until
the Manual Level Control (MLC) mode becomes active.
The MLC LED indicator lights up green. If the audio level from your
source is too high and exceeds the maximum permitted level, the sound
gets distorted and the MLC LED indicator changes to red.
2 Use the MLC rotary knob to manually adjust the audio level. If the
maximum permitted level is exceeded, turn the knob counterclockwise
and position it to the point just before where the MLC LED indicator
