Don’t buy these.
These are Apple In-Ear Headphones, and they are horrendous. They work in 2 modes: 1. “falling incessantly out of your ear” and 2. “plugged like a bad head cold at the bottom of the sea”. Some times they mutate from mode 2 to mode 1 without warning.
Prior to this I had a pair of Bose earbuds which worked just fine until I accidentally destroyed them (my bad). The apple ear-clogs are almost as expensive and sound one tenth as good as the Bose. I will be getting a new pair of Bose forthwith.
Apple you make nice computers, but between this and the (snicker) Hi-Fi, I’m less than impressed with your audio chops.
