transmitted by the connected Sennheiser
Communications headset will never exceed the
maximum of 85 dB (A) per day as a time-weighted
average* value, which is in compliance with the EU
Noise Directive**

breakdown of a typical working day and measured as
the sound pressure level with a B&K HATS (Head And
Torso Simulator)
** EU Directive 2003/10/EC on the minimum health
and safety requirements regarding the exposure of
workers to the risks arising from physical agents

volume of the headset speaker.
“Dynamic Volume Control” ensures that the volume set
via volume control is kept constant, even if the other
party speaks with varying volumes.

Warranty regulations
The guarantee period for this Sennheiser product is 24
months from the date of purchase. Excluded are accessory
items, rechargeable or disposable batteries that are
delivered with the product; due to their characteristics these
products have a shorter service life that is principally
dependent on the individual frequency of use. The
guarantee period starts from the date of original purchase.
For this reason, we recommend that the sales receipt be
retained as proof of purchase. Without this proof (which is
checked by the responsible Sennheiser service partner) you
will not be reimbursed for any repairs that are carried out.
Depending on our choice, guarantee service comprises, free
of charge, the removal of material and manufacturing
defects through repair or replacement of either individual
parts or the entire device. Inappropriate usage (e.g.
operating faults, mechanical damages, incorrect operating
voltage), wear and tear, force majeure and defects which
were known at the time of purchase are excluded from
guarantee claims. The guarantee is void if the product is
manipulated by non-authorised persons or repair stations.
In the case of a claim under the terms of this guarantee, send
the device, including accessories and sales receipt, to the
responsible service partner. To minimise the risk of
transport damage, we recommend that the original
packaging is used. Your legal rights against the seller,
resulting from the contract of sale, are not affected by this
guarantee.
