I was waiting forever for good quality bluetooth headphones and Apt-X was promising just that. However, I wasn't too keen about having a dongle... Some time ago Apple supposedly started using Apt-X in iMacs and Mac Minis; they didn't mention it in tech specs, but if you look on some Creative products in Apple store, Apple mentions it there (weird, isn't it?). Supposedly every Apple product now uses Apt-X. But how to check that? I'd rather verify that before I drop money on Bluetooth headphones. Without Apt-X, the quality will probably be quite appalling... With Apt-X, should be pretty good. Any ideas?
