The Sony WF-C510s are down to $34.99 on StackSocial, and for anyone just looking for decent sound without the sticker shock, this deal might do the trick. These are refurbished but listed as Grade A, so you’re getting a near-new pair at a discount of over 40%. They come with a compact charging case, a few silicone eartips for fit, and most of the core features you’d expect in 2025, including Bluetooth 5.3, hands-free calling, and fast pairing with Android and Windows devices.

The earbuds use Sony’s DSEE tech, which basically tries to clean up compressed audio, giving you something closer to the original sound. It’s not audiophile-level, but vocals come through clean, and the bass has decent punch. The real benefit is in the battery life: You get 11 hours per charge, plus another full round from the case, which is better than most earbuds at this price. There’s also a 5-minute quick charge option that gets you another hour, which is handy when you’re in a rush.

They’re light (around 4.6 grams each), IPX4 sweat-resistant, and designed to actually fit the human ear thanks to years of Sony data (which makes a difference if you’re using them for long stretches). The Ambient Sound mode is fine—it lets in just enough noise so you’re not startled by a passing cyclist—but don’t expect anything too smart. If you're someone who needs ANC or lives on Zoom, this probably isn’t your pair, but if you want something that sounds good, fits well, and doesn’t require babysitting, this is an affordable option with few real complaints.
