When first setting up your IQbuds™, use the Personal Profile settings to customise the settings to your hearing.
There are 5 settings that can be selected independently for each ear:
1 = no boost (for younger people with good hearing)
2 = low pitch boost (rarely used for people needing a mild low frequency hearing loss)
3 = very mild high pitch boost (for people over 25 with good hearing)
4 = mild high boost (for people who hear high pitched or children's voices as slightly muffled)
5 = moderate high pitch boost (for people who struggle to hear high pitched or children's voices)
