That’s the wired. Here’s the Wireless version for $39.
I have this speaker. The clip on it actually just broke(100% my fault) and this is a great value for a replacement. The speaker gets very loud for it size and took many falls, hits and scratches as I carried it around my job and still worked and sounded perfectly fine. Definitely worth the money.
I have had one of these for about two years. Good sound and a surprising amount of bass from a small unit. Recommended.
That is the non-Bluetooth version.
