Closetmaid will send replacements, but be prepared to wait. These headphones are great for the price. the sound is muffled and is almost like listening through a wall. Ordered these for an upcoming vacation where I will be walking a lot. The GoodThese sound very good and have a good in ear fit if you are used to wearing universal IEMs. Work well with my solo headphones. It even, contrary to some reports on the web, had adjustable feet so you can level it. What can I say about the price, its AMAZING! I have a cat peeing on my couch problem. Je la télécharge donc et tombe sur une appli franchement mal pensée, peu pratique et moche de surcroît.
