Coluna wireless Logitech praticamente sem uso. Como novas.
The Z515 is made of a tough black plastic and has two 2-inch drivers mounted on the front of the speaker, but they're hidden behind a solid mesh grille to protect them from the elements. We're not thrilled with the aesthetics of the speakers, and it feels clunky and boring next to the Creative D100's four color options and oval construction. The Z515 feels tough, though, and although the Creative D100 is actually a bit lighter, the Z515's overall footprint is still smaller and actually feels stronger thanks to the extra heft. Logitech also includes a zippered carrying case made of ballistic nylon to shield the device even further.

Aside from the two drivers, the front panel is almost bare, save for two small LEDs for battery power and connection status. A thick plastic foot pops out of the back for free-standing operation, and you can store the wireless USB dongle in a small yellow pocket underneath. The volume and power buttons live just above the foot, and although they're all lined up horizontally, each one is shaped differently, which makes it easy to distinguish them without looking. Finally, two rubber feet sit on the very bottom of the speaker to brace it against a tabletop while in action.

Unlike most portable speakers that can only connect through Bluetooth or an external 3.5mm auxiliary jack, the Z515 also includes a wireless 2.4GHz USB dongle for your laptop that can play wirelessly from around 50 feet away. This way, you don't have to deal with switching between Bluetooth on your computer and the same profile on your phone.
