Der Pfeffer schmeckt soooo gut ! It works, and does cancel the high pitched noises that annoy and distract me the most. I wish the metal hangers were slightly rounded. To answer the obvious why not return question. Tested the device as follows, remote inside the house, fob outside, fob/finder still sounded. I do think it was a little pricey, but it was hard to find a shoe rack that was thin enough and also had A table top in a agreeable price range. The controls are also amazing on the earbuds and the manual is also very useful so it can answer many questions you want to know about the product. I bought them the last week of February and waited for the weather to warm up to wear them. No tips left stuck in ear! I opened the package and there were so many tiny pieces of styrofoam everywhere.
