eAR OS是基于Ubuntu的Linux发行，它的特色在于功能强大且易用的eAR媒体中心。它可以用来接收电视节目，将CD音轨以无损FLAC质量保存到硬盘上，收看数字电视及DVD，收听Internet无线电广播，查看照片，或者收听音乐。这一切都集成到一份直观的用户界面中。该发行提供两种版本，一种是可免费下载的自由版本，另一份是商用的企业版本，后者包含额外组件及性能上的增强。
Peter Thomsen has announced the availability of an updated version of eAR OS, an Ubuntu-based, multimedia-oriented distribution: "The new eAR OS version 1.10b has been updated to use the new Firefox 3 browser with the Medialayer Connectivity plugin to watch movies on the Internet. This version is faster because now the graphical rendering of the eAR Media Center is hardware accelerated, it comes with a brand new theme for better look, you can select a username and password of your own choice, and it comes with many other improvements. All packages are the very newest and it comes with the latest Real-Time Linux kernel. The installation is easier too: if you want it to be up and running after installation to the hard disk with a minimum of tweaking, then enter 'earmusic' to be the username and select a password of your own choice."
