Bought a pair of new hearing aids...

Just now I went to Suntec city to collect my Music Pro SP (Super Power) and tried them on. I found that they serve me quite well even though the previous model serve my hearing better as it produces more distinct and clearer sound with wider range of frequencies.

Prior to buy this Music Pro SP, I request for the older model which I have been wearing for past 3 years. This model is called Prisma 2K SP and it is definitely more expensive. My audiologist said that this model would not be available anymore and would be taken off the shelf. I have no idea of why this model would be taken off this shelf. Since this Music Pro SP still provides me with rudimentary hearing need, I do not see it as a big cost burden and I decide to buy it anyway.
