This mini stereo speaker for MP3 players, laptops or mobile phones has a unique ﾑbellows' spring feature that means it can be extended up to increase amplification and improve sound quality.

Listening to music through headphones is ideal when you're on the bus or train, but sometimes you want more volume. Now that most of us carry our whole music collections around with us on phones or MP3 players, being able to plug music players into speakers for more amplification is a must.

The Spring Speaker connects to music sources via a 3.5mm audio input cable and charges via USB. Both cables are included and a two and a half hour charge will give around four hours of playback time.
