Amazing, small and lightweight but perfectly formed and an essential accessory for any owner of an iPod, iPhone or MP3 player, this ultra portable rechargeable pop-out speaker is perfect for listening to your favorite music when you re on your travels or out with friends and family. With its bottom panel extended out and bright blue power LED indicator, operating this device of 3 in diameter is disarmingly simple. There is only a power switch, an audio cable of about 4 length and a plug which you insert into audio sources such as MP3 players, mobile phones or notebook computers. There are also four mobile phone audio adapters so that you can blast music from compatible phones of brands like Sony Ericsson and Nokia. The speaker also comes with a USB cable for recharging its battery. To pack away the gadget, just push the bottom panel into the capsule. Push the panel again and the base pops out and it enhances the bass sounds.
