Does anyone have experience with high-end hearing aids? [View all]

My sister just told me about her new hearing aids - Oticon Delta - they cost $6,000 for both ears. She said they're wonderful and she can hear everything. My hearing problems are more severe than hers, but I'm wondering whether these would be beneficial to me. I'm receiving an inheritance that would allow me to purchase these, if suitable for me. I have great difficulty on the telephone, especially. These aids have multi-directional microphones and you'd be able to filter out undesirable background sounds, etc. I do hesitate, though, to spend that amount of money.
