Anker SoundBuds Slim, $22 with code 35SUMMER

Anker’s SoundBuds are our readers’ favorite affordable Bluetooth headphones, and the smallest version is back on sale, if you need another pair to keep in your gym bag or luggage.

The SoundBuds Slim are, as you might have gleaned from the name, far smaller than the originals. Heck, they look like a small set of wired earbuds; you might never guess there were batteries and Bluetooth radios in there. Despite the size, these buds are still rated for seven hours of battery life, and recharge fully in just 90 minutes.
