I bought the black one and the chain is gold color. Not sure of the ink bag.

You need a WiFi Internet connection, and a smartphone or tablet for the Echo App. That's it. It is easy to set up, but it may take you a while to figure out all of the little things that the Echo App can do.

BEWARE this is NOT STEREO and it is NOT MONO. This is only one channel. You will not hear part's of songs (recorded in stereo) that are only played through the left channel. Kinda ridiculous. Still it is a decent sounding speaker.

★★★★★ Great bag
Purchased this for my 23 year old daughter in the butterscotch color. Great versatile color. She loves the size -- perfect for day or going out at night. Chain can be double to shorten for nighttime and left long to wear as a crossbody during the day.
