ABSTRACT
Background:
The RONDO is a single-unit device that merges both the OPUS 2 behind-the-ear audio processor and the coil into a single housing. The study aims to assess the perceived auditory abilities and opinions of newly implanted subjects using the OPUS 2 and/or the RONDO in everyday life.

Material and methods:
We studied 83 newly implanted subjects who received the RONDO and OPUS 2 and were free to use whichever processor they preferred or a combination of the two. User satisfaction was evaluated after at least 4 weeks of use (after the first fitting) using the device-specific RONDO questionnaire.

Results:
Results showed that 77% of subjects were satisfied with the RONDO in general, and 92% of subjects either preferred to use the RONDO or liked both audio processors equally while wearing eyeglasses. Overall, 91% of subjects would recommend the RONDO to other CI users. RONDO was significantly (p<0.05) preferred at home, for cultural events, or when wearing glasses; OPUS 2 was preferred for sport or while wearing a cap.

Conclusions:
The RONDO was associated with a high degree of user satisfaction among newly implanted CI users and offers CI users further options in terms of wearer comfort and cosmetic appearance. Thus, CI users can, if they wish, switch from the OPUS 2 to the RONDO without affecting their hearing ability or speech understanding.
