Since there is no software or networking to be done with this media streamer, you can convert your music to digital right at your stereo system. The touchscreen navigation of the O3HD allow you to easily and quickly choose your music, make playlists, and get to your favorite internet radio stations (this media streamer gives you access to 3,000 internet radio stations from around the world). With the iPhone remote application, you can turn your iPhone or iPad into a remote for the O3HD, and control it from anywhere in your home. The quiet-working hard drives and fanless cooling ensure a noiseless performance from the O3HD. The Olive O3HD differs from the higher cost Olive 4 in that it can only hold 1,500 CDs (as opposed to 6,000).
