The ultra-affordable Soundcore by Anker P20i True Wireless Earbuds are on sale at Amazon for just $19.99, which means they're half-off the usual price of $39.99. At this price, you can use them as stocking stuffers or grab a few pairs for your family to always have on hand in case someone's earbuds go missing.

Not 48 hours before the writing of this piece was I entertaining a party with one of the very speakers on this list — the Soundcore X600, which is now $149 at Amazon — a $50 saving. It kept a group weekend in the countryside going with some incredible loudness, excellent sound, and top-notch battery life.
