All study participants must meet the following inclusion criteria:
• Age: = 18 years
• Mother Tongue: German
All CI users must meet the following inclusion criteria:
• Unilateral CI users
• CI speech processors: CP900-Series or CP1000
• Hearing experience with CI: = 6 months

Normal hearing participants (NH-group) show on both ears the following hearing level and CI users on the contralateral unaided ear the following mean hearing level (four pure tone average, PTA4):
• SSD-CI: PTA4 = 30 dB HL
• AHL-CI: 30 dB HL < PTA4 = 55 dB HL
• UniCI I: 55 dB HL < PTA4 = 80 dB HL
• UniCI II: 80 dB HL < PTA4
• NH: Hearing level = 20 dB HL up to 8 kHz
• cognitive disabilities
