This mini stereo speaker for MP3 players, laptops or mobile phones is lightweight, portable and has a unique ‘bellows’ spring feature that means it can be opened up to enhance amplification and sound quality.

Listening to music through headphones is great when you’re on the bus or train, but sometimes you want more sound. Now that most of us carry our whole music collections around with us and even CDs are a thing of the past, being able to plug music players into speakers for more amplification is a must.

If you want some speakers that are small enough to carry around with you, but give great sound, then these are the answer. The clever bellows type spring means that there’s an extra sound chamber to amplify the output, which also means that bass response is improved.

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.
