Okay, it is excellent that the Starkey aids does the trick for you when you are listening to normal conversation
The problem for your particular hearing loss with the Starkey Wi hearing aid and other hearing aids with the same output limitation (OSPL90) will be at louder sound environments than normal speech. This could for instance be when you hear a person playing the piano or a guitar or when you are listening to louder conversations. The physical limitation in how high sound levels the receiver can produce will namely imply that sounds above a certain sound pressure level simply cannot be produced by the receiver. This is also the reason why both SUPER440 with Power receiver and Starkey Wi with “absolute power” receiver is recommended for hearing losses below 90-100dB HL.
In other words the only reason why I recommend a more powerful hearing aid to you than the Starkey aids you are considering are that you most likely will be able to have a better hearing in the louder daily life sound environments… The most powerful hearing aids at the moment are (beside SUPER440) BTE hearing aids.
