Product Description

*Free 2 year guarantee*

Siemens Gigaset SL785 Cordless Phone meet the highest standards regarding design, technology and environmental friendliness. A unique design concept using solid metal underscores the high quality of the handset and charging cradle. Special emphasis was placed on ease of use: Users can move through the newly designed menu system with its intuitive icons using a central 5-way navigation key (four direction keys plus a middle key) on the handset. Metal dome key technology with its clear pressure point gives a completely new feel. Ideal legibility is ensured by the large TFT QVGA color display with 256,000 colors (240 x 320 pixels). In addition, both phones offer excellent sound quality even when used in full-duplex handsfree mode. If desired, users can also mute the phones and define VIP users. When the latter call, an acoustic signal is emitted despite the fact that the phone is muted.

All contacts under control

To enable efficient contact management, the Gigaset SL785 have a large address book, offering space for up to 500 entries in the vCard format. Thanks to the Gigaset QuickSync software, data can easily be synchronized with a PC (Microsoft Outlook) via the mini-USB cable or Bluetooth. The new phones’ handset also has a calendar so that users can keep track of all their important appointments. The integrated answering machine in the Gigaset SL785 can record up to 45 minutes of messages.

Environmentally-friendly and miserly with energy


The Siemens Gigasets SL785 are equipped with cutting-edge ECO technology and have an energy-saving power supply that consumes up to 60 percent less electricity than conventional phones. In addition, energy can be saved in the ECO mode, which cuts transmitting power by 80 percent during calls. And with the aid of the new ECO mode Plus, transmitting power is shut off completely in standby and recharging mode and only reactivated when a call is received or made.

Future-proof and expandable

To make sure they are always up-to-date, the Gigaset SL785 offer a simple means of updating their software or adding functions via the Internet. In conjunction with a Gigaset IP base station, broadband voice transport via HDSP (High Definition Sound Performance) is supported. The base stations of the new Gigasets can operate with up to six handsets. If desired, cordless Bluetooth headsets can be registered or headphones with a Slim Lumberg jack used. Both phones can also be combined with the Gigaset HC450 intercom.

EXCELLENT GIGASET HANDSET Cheeky_13astard_Esq 5/5 roll over for details

Good points This phone is by far the best I have ever used. YES i know its expensive and I was in two minds whether to purchase it but after seeing the competition - I have no doubt I made the right choice - THe phone is EXTREMELY EASY to use - its just unbelievable how logically Seimens have laid down all the menus and options - The quality of the handset is just incredible - the screen quality just oozes with sophistication the ring tones are amazing - if anyone wants to see what this phone is like in action just got to and type in sl785 or sl780 and you will see two people who have done a review - it will impress the sceptics - i have been waiting since November 2008 for this phone and have been extremely patient - now I know the wait was worth it - Ligo themselves are an amazing company - very helpful on the phone - super fast delivery - i have checked out all the other phone companies in the UK on google - they are totally crap - they are clueless - ringing their customer service just left me with a bitter experience - However Ligo is good - AND NO i dont have shares in Ligo or work for them HAHA

Bad points Well its a pricey piece of kit - but i ask you this when people buy mobile phones such as an IPHONE they end up paying 700-800 quid and they replace mobile phones annually - when people buy cordless phones for the home they keep them much longer so at just over a 100 quid per handset for what it does - ITS IMPRESSIVE

Other thoughts

I m a fussy buyer and I just cant fault the handset - i wish I could but features such as putting music for callers on hold - the soothing melodies etc etc IM in love with this phone - its the next best thing to my gf and sliced bread

5th Feb 2011

I find it impossible to believe this is an impartial review !
16th Feb 2011

I have had a pair of these phones for about 2 weeks now. I am very impressed. I am participating in at least 1 telephone meeting per day and these phones are just brilliant. The mute function is very good, easy to use. I can transfer contacts from my iMac via bluetooth very easily. The sound quality is good.

However, the most impressive thing was the packaging. I am sick of excessive plastic and those that you cant get back into the box for love nor money (as sending back gadgets due to being unfit for purpose is such a common occurrence these days). I am please to report it looked like this dual handset package was put together by human hands. One large cardboard branded box, together with individual cardboard boxes containing the charger, base station and batteries. The handset components were sealed in plastic sleeves. Not one bit of vac sealed clear hard plastic in sight.

Well done Siemens and liGo. Highly recommended for SOHO and home use.

Can the ringer of the handset and base be switched off completely?
Any audible caller id?
10th May 2011

Yes you can switch the ringer offer completely. I haven't checked for audible caller ID but it does show pic of the person calling you etc.
21st May 2011

Can you connect via bluetooth to a PC to make calls from within Outlook?
21st May 2011

Could you tell me if this phone has a caller display facility ?
5th Jun 2011

I have the SL375, and that has audible caller ID, by defining the caller as a VIP, you get to choose the ring tone. The hard part was finding a suitably morbid tune for my mother-in-law.
9th Jun 2011

Can you buy additional handsets
27th Jun 2011

Yes. The additional handsets are sold as the SL78H

First purchase from LiGo. I ordered a quad set of SL785s via the internet on 3 July 2011 (a Sunday). The phone arrived by courier on Tuesday 5 July! Well pleased. The phones took no setting up. Synced with my address book on MacBook Pro using the downloaded QuickSync software from Seimens website. I used USB, although I understand I could have used Bluetooth should I have wished. Phones have been great - better than anything I've used before, although I hadn't set the bar too high, having used only BT phones previously. One stand/ charger proved to be faulty. Used LiGo's online customer service facility on Tuesday, 9 Aug to which I received a prompt acknowledgement and within 12 hours also received and email advising of dispatch of replacement unit. No fuss, no bother. The replacement (new) unit arrived today, Friday 12 August. Despite the faulty unit, I'm well impressed all round with the phone system and especially by LiGo's service.
16th Aug 2011

Does it have speaker??? thanks
17th Aug 2011

I am really struggling between getting an SL785 and an S795. The reviews for both are excellent. I'm not sure what value the bluetooth of the 785 adds as I don't need to use a bluetooth headset as I happily use a headset with a jack at present, which the 795 has. The 795 is cheaper and more recent. Are there features of bluetooth capability that I am unaware of? Which phone has the best soud quality - this is the most important aspect for me - thanks very much - Joy
19th Aug 2011

Nobody comments on signal strength and the distance from base unit - can anybody enlighten me please. I need a strong phone to work in a 17th century building with the base unit in an upstairs office and the handset being used in a noisy commercial kitchen downstairs.
All comments welcome
31st Aug 2011

Re handset range: I've seen advertised a gigaset repeater unit - perhaps this would help?

I need to replace my home phone and am searching for a cordless phone with a number of handsets with extra long range as I live in a large old house with solid walls that I do not want to wire into. What is the range of this phone and does it need a booster after that?
23rd Dec 2011

Any idea how to get the Caller ID working? all I get at the moment is external on the display even a number in my phone book.
31st Dec 2011

external on the display is usually your telecoms provider and not the handset. You need to check if caller ID is included in your line rental package with your provider. Had a similar problem myself and this is what it turned out to be.
10th Sep 2012

I have 4 c470 Siemens gigaset cordless phones. Is it possible to pair this phone to previous gigaset models?
28th Nov 2012

can you transfer recorded messages from the answer phone to your pc or memory stick?
28th Dec 2012

Can I use this telephone system with my Siemen's hearing aids and MiniTek. There don't seem to be any reviews by the hard of hearing customers.
4th Jan 2013

I have an old gigaset which annoyingly does not log incoming calls in call history once received. Can any of the users please tell me if this one shows incoming calls in call history?

WOW! Anonymous 5/5 roll over for details

Good points I really dont know where to start. Firstly it looks amazing. Metal case and a truley gorgous display. I love it! It has all the usual features (and then some more). The sound quality has been great too. We've not had it for a very long but I'm so glad we bought this instead of another model we had in mind.

Bad points Didnt come out sooner.

Other thoughts

Can I add more handsets to it?

19th May 2010

i just got this phone today after waiting several months - siemens finally got their act together - the phone is absolutely amazing for a cordless phone - it just looks like nothing else on the market and really beats the competition by miles - i cant believe other companies such as philips and panasonic cannot produce something worthy like this - Ligo has been super helpful - great company - many thanks - great feedback from others helps a lot in making an informed purchasing decision - great website
