Amazon’s Echo Dot is a great voice assistant, and a truly terrible speaker. But for just $20 (with promo code OHRCFK7P), you can drop it into this speaker base, which replaces its puny 3W driver with a stereo pair of booming 10W drivers. Plus, the built-in 5,000mAh battery pack lets you move it all around your house, and even doubles as a smartphone charger.
Note, the black one doesn’t have a ton of Amazon reviews, but you can read some more impressions on the white model’s product page.
