Gigaset SL400A Cordless Phone

Best in class sound quality

Endorsed by Which? and consumers alike for its sound quality; the SL400 enhances the clarity of calls above that of a standard analogue phone thanks to HSP technology meaning you can enjoy conversations free from glitches and interference. And with a dependable range of up to 50 metres indoors (300 outdoors), the SL400 allows you to roam freely round your home (it is also repeater compatible for those who require longer range).

Essential DECT features

To enjoy conversations hands-free, you can use the integrated loudspeaker on either of the two handsets or utilise the Bluetooth functionality to pair a compatible headset (the SL400 also works with the L410 Clip, a compact & wearable DECT speakerphone). Further benefits of Bluetooth include convenient synchronisation of contacts on your PC with the phonebook on the handset, which has space for 500 entries (3 numbers per contact); and for importing images and music files to further personalise your home phone.

Made in Germany

All of Gigaset’s phones are manufactured from their factory in Bocholt, Germany, and they pride themselves on the quality of their goods. As a top of the range model, the SL400A has been built from the finest materials and has undergone rigorous testing to ensure that it meets Gigaset’s exacting criteria for excellence. As an object of design as well as a function, the SL400A has been made to impress those who demand the best.
