It would be pretty gross if stores gave customers the ability to try on in-ear headphones. It's unsanitary and there would be a boat-load of ear wax at the demo stations, yuck. Due to this, folks kind of have to hope they like the in-ear headphones they buy based on reviews.
Apple has apparently found a solution to this and will be allowing customers to test out in-ear headphones at Apple Stores. Customers will be able to pick out which headphones they would like to demo and an Apple employee will give them a fresh pair of ear tips.
The "Demo Kit" program will begin this week at Apple Stores across the nation. If you've been eyeing some in-ear headphones, you can now give them a try before you buy.
