I know that every single BlackBerry needs to officially file its hearing aid compatibility report with the FCC but that is not always so easily accessible. I have quite a few friends with hearing aids or one sort or another so when I saw this knowledgebase article from RIM I knew I had to post it. In this article RIM describes the hearing aid compatibility of practically every BlackBerry available.
It also breaks down the ratings between M3/M4 and T3/T4. M4 is the higher rating and causes less interference with hearing devices. T4 is the higher rating for hearing aids with telecoils. You can read more about it in RIM’s whitepaper.
Let me know how well your BlackBerry works with your hearing aid if you have one. I am curious how well RIM takes care of this in terms of supporting hearing aids.
The following table lists BlackBerry smartphones rated for HAC and their respective M and T ratings.
