Sound Quality
Super wideband audio technology operates in the extended
frequency region from 100 Hz all the way up to 11.5 kHz.
Because the human ear has a range that goes from 20 Hz
up to 20 kHz, super wideband allows you to hear a more
natural, rich sound, where subtle details encourage a fuller
understanding of the spoken word. The IMPACT 5000
Series oers super wideband sound, letting you experience
a voice quality beyond conventional business standards.
To be able to use super wideband, all components of the
communication line must support this standard (including
end point and network infrastructure).
Wideband audio technology operates in the frequency
range of 150–6800 Hz and oers higher quality speech
transmission than narrowband. To be able to use wideband,
all components of the communication line must support this
standard (PPX, mobile network operator etc.).
Narrowband audio technology operates in the 300–3400
Hz frequency. As many traditional desk phones only support
these narrowband frequencies, we also have a range of
narrowband headsets, which deliver the best performance
available from this standard.
High density wideband mode is a wideband mode designed
for communication in high density environments and
provides excellent sound for more users.
Noise-cancellation technology is incorporated in our
microphones to reduce background noise, lter out
disturbing ambient noise and enable crystal clear telephone
conversations. On certain models in our range we oer ultra
noise-cancelling microphones, which are able to improve
voice transmission in particularly noisy environments.
Low impedance Some desk phone/devices have low
impedance output which means that the speaker output is
lower than most devices. Devices with low impedance output
need a headset which compensates for the lower speaker
output to ensure the same sound level as for
most devices.
Hearing Protection
EPOS ActiveGard
®
hearing protection technology protects
users from the potential danger of acoustic injury from
unexpected and sudden sound bursts on the line. EPOS
ActiveGard
®
is like a fast-acting intelligent volume control.
If an incoming signal rises to a level that is harmful to
your hearing, it is instantly reduced to a lower, and more
comfortable level. When the sound level returns to normal,
the volume returns to the original level.
Noise at Work Limiter
Directive 2003/10/EC The objective of this Directive is
to lay down minimum requirements for the protection of
workers from risks to their health and safety arising or likely
to arise from exposure to noise and in particular the risk to
hearing. The Directive denes the physical parameters that
serve as risk predictors, such as peak sound pressure, daily
noise exposure level and weekly noise exposure level. It sets
exposure limit values and exposure action values in respect
to the daily and weekly noise exposure level as well as peak
sound pressure. The exposure action value is xed at 80
decibels (lower value) and 85 decibels (upper value). Source:

Unied Communications
UC Optimized means that headsets and speakerphones are
compatible with major Unied Communications platforms and
softphone brands. Unied Communications brings together
a company’s voice, text and video based communication
under one unied solution. The advantages of a Unied
Communications solution include enhanced overall eciency
of a business through increased productivity and mobility,
resulting in a positive return on investment.
Microsoft Teams and Skype for Business Certied means
that products are certied for Microsoft Teams and Skype
for Business. Headset and speakerphones have been fully
tested to ensure compatibility with Skype for Business,
Microsoft Teams and Microsoft
®
Oce 365. You can simply
answer or end calls, adjust volume, or mute calls through the
headset or speakerphone’s call control features.
Wireless Technologies
Bluetooth
®
technology is a global radio transmission
standard, which supports the application of a wide range
of wireless electronic devices. The technology connects
devices over a distance of up to 100 meters in line of sight,
depending on the Bluetooth
®
class and device.
DECT is an abbreviation for “Digital Enhanced Cordless
Telecommunications”, a digital transmission standard for
wireless telephony. DECT is primarily used for wireless voice
transmission in oce and contact center environments.
DECT provides a cleaner, more stable sound and does not
interfere with nearby WiFi devices. In addition DECT protects
voice calls with highly secured DECT authentication and
encryption. EPOS’ Wireless DECT Headsets Solutions have a
range up to 55 m (180 ft) in typical oce environments and
up to 180 m (590 ft) with line of sight.
DECT vs Bluetooth
®
– One of the chief advantages of a
DECT solution is that it doesn’t interfere with 2.4 GHz WiFi,
whereas a Bluetooth
®
solution uses the same frequency as
WiFi. This means that it is possible to have more users in
the same area when a DECT solution is used. On the other
hand, a Bluetooth
®
headset gives more mobility as it can
connect directly with the user’s mobile phone. This gives the
user the advantage of being able to use it both in the oce
and on the go.
Wearing style
Single-sided headsets are ideal for situations where you
need to both hear your caller clearly, and pay attention to
what’s going on around you.
Double-sided headsets delivers calls in quality sound while
reducing background noise – ideal for contact centers,
where you need to focus solely on your caller.
Other
Easy Disconnect (ED)
is the plug that connects EPOS wired headsets to desk
phones, DECT terminals and mobile phones or a UC/
Skype for Business solution via the correct bottom cable.
Disconnect the headset from the bottom cable, simply by
pressing the ED plug. The spring loaded contacts in the ED
plug ensure reliable connection in everyday use.
Security
Protected Pairing EPOS’ DECT headset series have a
Protected Pairing feature (patent pending) ensuring a very
high degree of security. Rather than transferring pairing data
‘over the air’, the charging interfaces on the base station
are used for data communication. This means that a EPOS
DECT headset needs to be physically docked into a EPOS
base station for registration and security bindings to be
established. This makes it virtually impossible for a third party
to ‘sni’ or intercept the pairing data from a remote location.
