A week or so ago I purchased "a little black box". It is a noise cancellation device and you wear it as ear phones either small or large and it is connected to this small black box - around the size of say an ipod. You can use it on its own or even connect your ipod to it or the airline sound system.
It is amazing, I have only used it in the car so far and it cuts out all the back ground noise - you can still hear a person talking or on planes you would still hear announcements or hear films - but none of that horrid back ground noise. I haven't tried it in a mall yet but I do know that it will cut out that horrible back ground buzz which I can not tolerate.
They are actually made in NZ I paid NZ$179.00 which would be about US$120.00.
The best thing I have bought.

Thoroughly recommended.

PS - not been around as over did the walking - was given a pedometer and went crazy and brought back all the PCS symptons - bad headaches, vomitting major weight loss. The latter being the plus side of things!
