Product description
Adaptive Intelligence for optimal speech intelligibility
The new Bluetooth office headset BW 900 features unique Adaptive
Intelligence technology (patent pending) providing excellent sound quality. The BW 900 automatically compensates for ambient noise and “remembers” the user's preferred settings. During conversation, these
settings are adapted automatically in order to compensate for fluctuations in ambient noise levels.
Adaptive Intelligence also ensures that the interlocutor listening to the
headset user can enjoy optimum speech clarity.
ActiveGard™ for your well-being
The headset is equipped with ActiveGard™, a unique technology patented by Sennheiser Communications. It uses sophisticated sound pressure limitation systems to actively safeguard your hearing against
acoustic shocks. A safe and comfortable sound level allows for stress-free
work with the headset.
Stylish and lightweight, with high wearing comfort
Its discreet design is another plus of this headset. The fashionable and
lightweight device is placed behind the user’s ear. As it is barely noticeable, it is comfortable enough to wear it all day. It can be adjusted ergonomically for a perfect fit on any ear. The BW 900 blue-and-charcoal
design is unobtrusive. The small microphone boom impairs neither the
user's freedom of movement nor his or her field of vision.
More room to move
BW 900 is a Bluetooth Class 1 device supporting the version 1.2 standard. It provides long-range operation and maximum compatibility. With
the base station connected to your office phone, you can roam around
the building up to a distance of 100 m. Additionally, you can move up to
10 metres away from your Bluetooth-enabled devices such as mobile
phones, PCs and PDAs.
Optimum connectivity
The Bluetooth interface allows the BW 900 to be connected to several
devices. Whether you are using a mobile phone or other phone types
such as smart phones or soft phones – the BW 900 is compatible with all
types of speech-based Bluetooth devices. The user-friendly pushbutton

interface provides for seamless changeover between your fixed line
phone and any Bluetooth-enabled phone paired.
Non-stop talking
Should the battery run flat while you are talking via your office phone,
you can easily replace it with a fully charged battery without terminating
your call. While no battery is being connected, the BW 900 base station
maintains the connection to the telephone line.
Delivery includes
1 BW 900 base station
1 BW 900 Bluetooth headset

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

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.

that no national law limits our terms of guarantee.
