iBall has launched two portable speakers, the iBall Melody Bar and iBall USB Drum, at `890 and `990 respectively. The iBall Melody Bar, with dimensions of 22 x 4.5 x 5 cm, is a USB speaker that has been magnetically shielded so that it can be in close proximity with other digital gadgets. Its removable clips allow one to mount it on any laptop monitor either horizontally or vertically. A tabletop free accessory is also bundled. It supports full stereo sound through two high-performance drivers, a built-in amplifier and an acoustically tuned enclosure. The iBall USB Drum, which resembles a tabla, is a notebook USB speaker with plug-n-play facility. It works as both full USB speaker from the laptop or a stereo speaker with USB power from external sources such as MP3 players and iPhones.
