If you’re looking for a compact speaker that won’t flake out on sound or durability, this refurbished Sony SRS-XB100 wireless Bluetooth speaker is worth a closer look. It’s on sale right now for $34.99 at StackSocial (down from its original $59.99 price), and this Grade “A” refurbished unit arrives in like-new condition and ships free across the contiguous U.S. It’s not brand-new —those are going for around $48 on Amazon—but this version comes with barely noticeable wear, if any, and still delivers the same sound and features you’d expect.
Physically, the XB100 is built for portability. It’s just 3 inches wide and stands 3.8 inches tall, weighing under 10 ounces, which is light enough to toss in a backpack, clip onto a bag, or dangle from your wrist using the included lanyard. It’s available in black for this deal (with other colors like blue, orange, and gray also out there) and feels intentionally designed to tag along anywhere. On the audio front, you’re working with a modest two-watt driver and a passive bass radiator that somehow squeezes out clean mono sound with a little low-end punch. Don’t expect deep bass drops, obviously, but it holds its own for podcasts, acoustic tracks, or background music during a hike.
Controls are intuitive and built right into the base—everything from power and volume to Bluetooth pairing and playback. It connects using Bluetooth 5.3 and supports AAC and SBC audio codecs , which is pretty decent at this price point. Android users get a little bonus with Google Fast Pair, which cuts down the setup time to basically nothing. It’s also IP67 rated, so it’s waterproof and dustproof—you can rinse it off after a beach day or bring it poolside without worry. And with an estimated battery life of up to 16 hours, it’s designed to go the distance on one charge, notes this PCMag review .
