Oticon OPN 3
OPN3 is the most value-friendly version of the OPN line. Having said that, while it keeps costs down it still retains much of the technology contained in the higher-end versions. OPN3 has 12 channels for aligning the output of the aid to the user’s hearing loss, which is plenty for most hearing loss configurations. The Made for iPhone® connectivity is the same as any other OPN model and the basic noise removal system will help filter out competing signals in many everyday situations.
