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.
