title: Comparison of different mobile telephones in Combi40+ users.
abstract: CONCLUSIONS
  Telephone usage is a difficult challenge for cochlear implanted patients. A significant number of cochlear implanted patients are able to carry on a land-line or mobile telephone conversation. The telephone model may be a critical factor for telephone performance.
  
  
  OBJECTIVE
  The goals of this study were to evaluate speech discrimination through land-line and mobile telephones in Combi40+ users, and to compare different mobile telephone models to find out which could be more advisable for them.
  
  
  METHODS
  Eighteen Combi40+ implantees were tested with CID sentences and bisyllabic words presented through land-line and mobile telephones, in both quiet and noisy environments.
  
  
  RESULTS
  Mean scores for telephonic speech discrimination were over 85% for CID sentences and 28-59% for bisyllabic words. The Siemens M55 was superior to the other mobile telephones tested.
