Monster Cable BTW218 Tower of Music Wireless Bluetooth Speaker

No bigger than a shoebox, this speaker is easy to bring along to picnics, the beach, and tailgates, where it reproduces and amplifies the music and audio stored on laptops and smartphones better than those devices’ speakers can.

Powerful, Three-Way Sound

No matter where you’re sitting in relation to this speaker, the three-way sound speaker setup ensures you hear high-quality audio. Its dual 2.5” tweeters, front 3” full-range driver, and two 3” side passive radiators send audio in a 270° arc, helping minimize spots where the sound is muffled or warped.

Wireless Audio

Play and control tracks from across the room during a party, stream a podcast from your laptop while relaxing on the deck, or play wistful love songs dedicated to the audio cables that aren’t a part of your life anymore. The speaker’s Bluetooth technology connects it wirelessly with enabled devices, letting you play their audio without needing to hook up any cables.

All-Day Battery Life

A built-in rechargeable battery keeps the Tower going for up to eight hours at a time—long enough to soundtrack an entire party or cookout with battery life to spare.

Bought 2 to wifi together. Didn't link at first but finally did after retrying about 10 times. 1 of my units was definitely not brand new out of the box. It had some scratches and a dirt oil stain on it. Disappointed by that finding.
