I am looking at
Siemens Digital BTE High-Power LOTUS Hearing Aid
http://www.amazon.com/Siemens-Digital-High-Power-Hearing-Enhance/dp/B00UYK9ELM/ref=sr_1_3?ie=UTF8&qid=1429156259&sr=8-3
What is the difference between 12P, 12SP, 23P, 23SP, and GH03001?
I know this HA is not the best on the market. I’ll be using this aid
as a spare (right now, I’m using an ancient Oticon EP 50 as a spare
- whose know how long this 30+ years old HA will last). I want to be
able to use this HA on either side with frequency and power adjustments
using the trimmer (I don’t have a Iphone or Android smartphone to do
programming).
I am guessing the numbers are the frequency bands, correct? Is # of
frequency bands important for me if I am using the trimmer (I doubt
it)?
Thank for your help.
