Our patented audio technology, OmniSound®, is embedded into all Konftel phones to
ensure crystal-clear voice transmission. We’re now taking OmniSound® to the next level.
OmniSound® 2.0 provides the Konftel 250 with the capability to deliver an even more
impressive audio quality. Just like OmniSound® full duplex, OmniSound® 2.0 uses
an omni-directional microphone and three speakers for optimal audio performance.
OmniSound® 2.0 is enhanced with innovative features – noise suppression minimises
distracting background noise and an equalizer allows you to adjust sound levels during
your meeting.
Konftel AB hereby declares that this conference unit complies with all essential require-
ments and other relevant provisions of Directive 1999/5/EC.
Warning!
Do not expose the Konftel 250 to water or moisture.
