Description

Communicate more beautifully – with the Gigaset CL660HX.

For anyone who doesn’t want to compromise when it comes to looks and function: the Gigaset CL660HX cordless telephone. Ideally equipped for the future of telephony thanks to the possibility to connect to all routers that support DECT, e.g. the FRITZ!Box or the Telekom Speedport. Furthermore, the Gigaset CL660HX features a high-quality finish and flush-mount design.

  • HX universal handset for connection to any Internet router with a DECT base station
  • Brilliant voice quality, even in the hands-free mode
  • Customisation using own images and ring tones
  • Up to 400 entries in the telephone book
  • Connection to a PC or Mac via micro USB

Excellent looks and handling. That's how a telephone should be.

The flush keys underscore the telephone's high quality. The frameless illuminated keypad ensures optimum ease of use. The classic anthracite colour lends the cordless telephone particular elegance. The redesigned navigation key and the large high-resolution display fit in perfectly with the modern look and make the Gigaset CL660HX a real eye-catcher. 

Sounds futuristic, sounds brilliant.

One for all: The CL660HX universal handset is suitable for all common Internet routers, e.g. for the FRITZ!Box, the Telekom Speedport and many other models. You thus automatically use state-of-the-art Internet telephony and with the CL660HX you benefit from natural sounding audio quality in HD Voice. In addition you have numerous convenience functions at your disposal: a router-internal answering machine, access to the router's telephone book as well as lists of incoming, outgoing and missed calls.

Now it's a personal matter. With your own family photos and ring tones.

The CL660HX cordless telephone allows you to easily personalise your telephone with individual ring tones, your own photos and screensavers. Call display with a picture of the caller is also possible if you have stored the contact in your address book with a picture. Easily personalise your CL660HX using the free Gigaset QuickSync software, which you can download for your PC or Mac here.

Managing contacts? Not a problem with the CL660HX.

Manage all your contacts more easily than ever before using the Gigaset QuickSync software! The large address book of the CL660HX offers space for up to 400 entries with three telephone numbers each. You can quickly synchronise these numbers from your PC or Mac – very quickly via micro USB and with the address books of MS Outlook, Windows or Google Cloud. It's also possible to synchronise contacts with pictures. Another practical feature: VIP numbers and the birthday reminder function for particularly important people and events.

Beautiful at first glance, beautifully practical at second glance.

The Gigaset CL660HX wins users over thanks to its design and extensive features. Starting with the large high-contrast TFT colour display (50 x 38 mm), which guarantees optimum readability even in poor light. Practical functions such as the displays for date and time, new messages, call duration and battery status also make the telephone extremely user-friendly.

How nice when a telephone also provides peace and quiet.

You can easily avoid unwanted calls in general or specifically for selected numbers with the time-controlled call silencing function. Mute your CL660HX, for example, when your baby, your children or you are sleeping and don't want to be disturbed. Calls are still shown on the display, but the ring tone is switched off. With the "Anonymous call suppression" function you can reject or mute calls without a CLIP number. And with the blacklist function you can block up to 15 telephone numbers for incoming calls.

Stay up-to-date very easily!

Keep the software of your handset always up-to-date. The CL660HX makes it very easy for you, thanks to the QuickSync software. Connect your handset to your PC or Mac via USB, start QuickSync and perform an update. The handset always notifies you when a new software version is available.

Radiation-free thanks to ECO DECT.

Like all Gigaset cordless telephones, the Gigaset CL660HX is equipped with the environmentally friendly ECO DECT technology. This means that the telephones are radiation-free in standby mode, even if several handsets are used, as long as the base station and all registered handsets also support ECO DECT. During a telephone conversation, the transmitting power is automatically adjusted to the distance between the base station and the handset. The shorter the distance to the base station, the lower the radiation. For the maximum DECT range, the ECO DECT mode can be deactivated at any time.
