ZDNET's top-selling products from Prime Day 4

Bose's SoundLink Plus is in the upper-middle of its SoundLink lineup, and to headphone expert Jada Jones, it's the perfect size. "This speaker features four passive radiators, which help it produce a huge bass response, which is exactly what you need for an outdoor soiree. If you're by the pool, the SoundLink Plus can handle accidental drops in water thanks to its IP67 rating, which makes it dust- and waterproof," Jones says.

Our pick for the best Garmin watch you can buy, the Fenix 8 Pro is the latest flagship model that connects seamlessly to Android and iOS smartphones, in addition to golf club sensors, bike sensors, and more. Just about every sport is covered with an updated smartphone experience, so you can customize the watch settings on your phone and sync them over to the watch.

The smartwatch features a vibrant AMOLED display for ultra-readability, and an LED flashlight, which reviewer Matt Miller says "makes the Fenix 8 Pro an essential tool in my collection." This was our top-seller for Prime Day 1, and a top-5 seller for Prime Day 2.
