SPEAKERS ONLY WITH THE ADAPTER. NO POWER SUPPLY OR CORDS.

YOU WILL ONLY RECEIVE WHAT IS SHOWN IN THE PICTURES

Working really great but upgraded to the 700 surround speakers so no longer needed. Honestly, I think these work better than the 700 for most audio where the 700 pretty much only plays music and small environment sounds, these units play all sound and work extremely well. You will need the power bricks and cords to run these. They are compatible with the 300, 500 and 700 series options

I personally used these on my Bose 500 Bass Module and has not issues at all. Great surround speakers. 

The Bose Surround Wireless Rear Speaker System 300 or 700 in white is a sleek and modern addition to any home audio setup. With its virtually invisible design and wireless connectivity, it offers a seamless and immersive listening experience. The cube-shaped speakers are made of durable plastic and are designed to be placed in the rear of the room for optimal sound performance. Compatible with other Bose products, this unit is a top choice for those looking to enhance their TV, video, or music experience.
