The S25 Reportophone offers the reporter the possibility to connect to the studio from every place were he can use his mobile telephone. It is easy to use, offers very good protection against HF radiation and has the same features as the world famous S20A. Even the layout and function of the knobs is the same.

The audio quality is surprisingly good. You are getting the best possible audio from the 8 bit 8 kHz telephone system. Under normal circumstances you won't hear any distortion due to the radiation of the telephone.
A special application is the use in Advanced Multirate Wideband systems (AMR-WB / G722).

This "wideband audio" or "HD Voice" system increases the bandwidth and transmits in the audio frequency range of 50 Hz to almost 8 kHz. In combination with an S25 Reportophone, good microphone and a suitable mobile telephone audio quality improves to an extend that is very close to much larger and more expensive reporter systems.  
A number of carriers have rolled out HD voice services based on this G.722 wideband standard. Amongst others KPN in the Netherlands is also offering this system.

The S25 can also be used as a stationary hybrid in areas where no landlines are available.

To connect your mobile telephone to the unit a wide variety of cables is available for Nokia, Apple, HTC, Samsung,
Sony-Ericsson and others.
