Siemens Gigaset C595


The C595 comes with an integrated answering machine and fits comfortably into any home or small office.

The traditional Siemens build quality extends to the C595 and as such the sound quality is excellent.

Siemens Gigaset C595 Twin - Disappointing

  (Rating Hidden)

Is this really the phone that Which reviewed? It's dreadful. Slow to respond. Limited memory. Very poor sound quality. The only thing it's got going for it is longevity - have been waiting for it to break since the day I got it, but no luck yet.

Siemens Gigaset C595 triple - surprisingly poor

The good reviews are not reflected in the product in use. Poor range of useful ringtones, too many of them have been dreamt up by the marketing department and I'm sure would sound fine in a hushed executive office - just not in real life. Poor sound...
