This is a set of nearfield monitors equipped with Tectonic Audio Labs drivers. The speakers come in a black color and have dual force-canceling passive radiators for efficient audio performance. The audio inputs for this device include a 3.5 mm jack, and it can be connected through Bluetooth or wired connectivity.
The features of these speakers include ultra-compact drivers that are perfect for small form format, balanced mode radiation that ensures an even sound output, and a subwoofer output for added bass. The item is new in the box and is ideal for use with computers, laptops, and other networking devices.
Magnetic grills are available for these speakers in 6 colors for $25.00 a pair. (Do a web search. I can't put an external link in the listing.)
The UPC on the box is 810021186173. For some reason eBay won't let me enter that in the field.
These speakers can be mounted vertically or horizontally. I kept a set for my own use. See the last pic for horizontal mounting in my setup. They sound great!
