'ZDNET Recommends': What exactly does it mean? ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing. When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers. ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards.

Amazon's sale ends at 11:59 a.m. PDT, and we've been scoping out all the savings you've been scooping up -- and we're back with ZDNET's top-selling items (so far) from June Prime Day 4.  Also: Prime Day is ending: We hand-picked the 100+ best deals still live from Apple, Garmin, Bose, & more The following are listed in order of units sold through the links clicked from ZDNET stories. (A note: Your privacy is protected -- we only have access to aggregate data from our user base, and we cannot identify individual people's purchases.)  These are the top 10 products (in order) that ZDNET readers purchased so far during Prime Day 4 2026 -- and most of these great buys are still on sale (but not for much longer). Plus, shop our favorite Prime Day deals while they last.  Also: Thousands of readers bought these 15+ tech deals on Amazon Prime Day - most are still live Jada Jones/ZDNET 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.  Kerry Wan/ZDNET The AAWireless Two Plus enables wireless Android Auto and CarPlay connectivity, with a multifunctional button designed for quick pairing and switching between Android and iPhone devices. ZDNET Editor-in-Chief Kerry Wan says the gadget delivers the best wireless Android Auto experience yet.  Also: The wireless Android Auto adapter that I rely on for long commutes is 15% off right now Matthew Miller/ZDNET 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.  Adrian Kingsley-Hughes/ZDNET Prone to pesky bug bites? Heat It could be for you. It plugs into your phone (and it's available for USB-C or Lightning adapters) and delivers a warming zap that's supposed to quell itchiness from bug bites. I had to try one of these after our gadget reviewer Adrian Kingsley-Hughes tested it out, and I can confirm that it works. Also: This USB-C accessory gave my iPhone and Android a surprisingly useful functionality Garmin/ZDNET This Garmin watch gets a whopping 50% discount for Prime Day. It's a premium smartwatch and health and fitness tracker with a 47mm AMOLED display, protected by a sapphire face and a titanium bezel. It gets up to 16 days of battery life when in smartwatch mode. Also: Amazon is selling Garmin watches for up to $500 off - I've tested and recommend these models Jada Jones/ZDNET The AirFly Pro 2 is one of expert Jada Jones' must-have travel essentials, and it's on sale for under $50.  Also: I won't fly anywhere without this tiny Bluetooth dongle - it's 21% off right now Matthew Miller/ZDNET Garmin's Instict 3 Solar offers a smart selection of flagship features, and it's down to $349 during the last few hours of Amazon Prime Day. This matches the price it sold for during Black Friday. Also: Looking for an Apple Watch alternative? I recommend this Garmin  Christian de Looper/ZDNET This Anker speaker brings the boom. This one features party lights, 24 hours of playtime, and a handle for carrying. The Soundcore Boom 2 has an IPX7 rating, meaning it can withstand submersion in up to 3 feet of water for 30 minutes. The good thing is that the Boom 2 floats when dropped in water, so it's easy to retrieve.  Also: Bluetooth speakers aren't created equal - here are the 5 I'd buy for Prime Day before they're gone Jada Jones/ZDNET JBL's Charge 6 speaker is packed with features, including Auracast, USB-C reverse charging, lossless audio via a wired connection, and 28 hours of playtime. The Charge 8 has an IP68 durability rating, making it capable of surviving drops in water for an extended period. It's also 20% off now.
