Apple recently launched iPod Shuffle with a new feature VoiceOver. It also has a big change, no control buttons except the Shuffle, Play in order and Off. The functionality is quite limited if not use with the default headphone. When you switch on the shuffle with anything plugged into headphone jack it starts playing but there is no way to navigate between the songs and playlists.
I have iPod Nano and iPhone. Sometimes I use them with external speakers using 3.5-mm stereo jack. But iPod Shuffle 3rd Generation can’t be used with other speakers because of lack of control panel. There is same compatibility problem with 3rd party headphones.
