Amazon.com Product Description:
The SRS-A27 desktop speakers will morph your personal CD player or radio into a substantial sound system. They will accomplish this morphing with minimal cost. These speakers are Sony's basic, yet highly sensitive speaker. With their compact size and shape, these speakers are perfect for a dorm room or office. The two watts of power, along with the 57 mm driver units provide quality sound with a wide frequency. To enhance the bass sound, Sony has installed a built-in Mega Bass sound; this boosts the sound quality, especially at low frequencies. With magnetic shielding, you can be confident that the speakers will not harm the quality of other near-by components, like a TV or computer monitor.

You have two options for powering these speakers. Choose either an optional AC adaptor or four AA batteries (not included.) The speakers will play up to thirty hours with Sony alkaline batteries. There is a single, mini-jack input located on one of the speakers. The on/off switch and volume control are also located at the front of one of the speakers, making adjustments easy to accomplish. The two speaker cords are one meter long. Take your Walkman, Discman or computer to a new level with these active, bass-heavy speakers.
