Insten Folding Stereo Speaker
Headphones and ear buds are a great way to listen to music from your MP3 players but sometimes, even while on the move, you just want to share your sounds with your friends. While you can’t carry those huge home speakers when moving around, what you can carry is a 4.40″ x 2.40″ x 2.40″ miniature folding speaker. These are the exact measurements of the Insten Folding Stereo Speaker.
The speaker supports a long list of players: iPod Nano, Video, Photo, Mini, Shuffle, and Classic; Apple iPhone 3Gs; Microsoft Zune; and all audio equipment (MP3, DVD, and CD players, as well as laptops) with a 3.5 mm plug.
Its frequency response of from 150Hz to 18kHz, though not the high fidelity that hard core audiophiles seek, is quite good considering its size. Users claim that its sound compares favorably with a factory-installed sound system of a compact or sub-compact car. This means that is better than the built-in speakers of most laptops. Its output is rated at 1W x 2. The signal cable is 22 cm with an ST gold-plated 2.5 mm plug. The speaker measures 50 mm and is rated at 4 ohms.
The casing is made of aluminum making it a lightweight device weighing less than half a pound. It is available in black and white. Power is supplied either by 4 size AAA batteries, a supplied USB cable, or an AC 6 volt adapter.
