Sony's small, but still powerful, XB20 Bluetooth speaker is currently on sale over at eBay, coming in at just $39.99. This speaker is usually around $99.99, so this is a huge price drop, and makes it a great time to pick one up. This is a manufacturer refurbished model, however, so you'll want to keep that in mind.
The Sony XB20 is part of the company's Extra Bass lineup of speakers and does provide some incredible sound for such a small Bluetooth speaker. As you'd expect from the Extra Bass lineup, it does provide some incredibly deep bass from the speaker. It does also provide some great sounding mids and highs as well. The XB20 does offer some great battery life, lasting around 12 hours or so of continuous playback. On top of that, the Sony XB20 can also take a splash or two and even go swimming, as it is waterproof. Sony has also continued to add NFC functionality to its speaker here, making it easier than ever to pair with your smartphone.
eBay does offer up free shipping and there are no taxes on the Sony XB20 Bluetooth Speaker. Making it a great purchase for those looking for a new speaker to add to their collection. This would be a great one to add to the Echo Dot, for some better sounding audio from Alexa.
