Clip on laptop speakers.

Plugs into 3.5 mm Jack and also usb,  draws power from laptop, so you don't have to recharge them.

Fairly good sound. Not overly loud. Adjustable in line volume control.

My laptop lid is particularly thin, and I needed to use a little piece of leather in the clip to keep them tight.

I felt they were a little awkward perched on top. I taped to lid .

As always;   smoke-free, pet-free, fast ship
