We present ShoppingComp, a challenging real-world benchmark for rigorously evaluating LLM-powered shopping agents on three core capabilities: precise product retrieval, expert-level report generation, and safety critical decision making. Unlike prior e-commerce benchmarks, ShoppingComp introduces highly complex tasks under the principle of guaranteeing real products and ensuring easy verifiability, adding a novel evaluation dimension for identifying product safety hazards alongside recommendation accuracy and report quality. The benchmark comprises 120 tasks and 1,026 scenarios, curated by 35 experts to reflect authentic shopping needs. Results reveal stark limitations of current LLMs: even state-of-the-art models achieve low performance (e.g., 11.22% for GPT-5, 3.92% for Gemini-2.5-Flash). These findings highlight a substantial gap between research benchmarks and real-world deployment, where LLMs make critical errors such as failure to identify unsafe product usage or falling for promotional misinformation, leading to harmful recommendations. ShoppingComp fills the gap and thus establishes a new standard for advancing reliable and practical agents in e-commerce.

No matter what kind of content you consume, sound quality makes a world of difference, and these wireless systems allow for impeccable quality without pro installation. Most systems include a soundbar as well as satellite speakers and a subwoofer, all of which communicate wirelessly with no delay. We've tested some of the most popular and powerful wireless soundbars and systems on the market and came up with these recommendations for any type of viewer. Still, the Samsung HW-990F reigns as the best overall wireless soundbar, but the competition gets closer all the time. I [Markkus Rovito] have previewed and reviewed products--both in the pro audio and home audio realms--on and off throughout most of the 21st century for outlets including Mix, Maximum Tech, DJ Tech Tools, Bob Vila, and some defunct publications printed on paper called magazines. Between the PopSci staff [Stan Horaczek, Tony Ware, Brandt Ranj], we've tested variations of these wireless surround sound systems firsthand. Beyond our own favorable experiences, these wireless surround sound systems have all proved popular with expert reviewers. Each of these systems offers something a little different from the others, but they all include rear satellite speakers because we wanted to limit this list to systems that actually surround you with speakers.

Breakthroughs, discoveries, and DIY tips sent every weekday. Most computer, TV, and home theater setups are going to involve HDMI somewhere along the line: The High-Definition Multimedia Interface format is now fairly ubiquitous on everything from laptops to cable boxes, and so when a new version of the standard turns up, it's worth paying attention to. Almost eight years after the release of HDMI 2.1, and nearly 12 years after HDMI 2.0 was pushed out into the world, HDMI 2.2 is finalized and ready to go. You'll now start seeing mentions of it in product listings and tech guides, and we'll explain here what's different and what isn't about the new standard. The headline upgrade here is the jump from 48 gigabits per second to 96 gigabits per second for the maximum possible transmission bit rate.

Most of the time, the best TVs for gaming are the best TVs you can buy, period.

While nobody needs a fancy TV to just enjoy a video game, the right set can help you maximize your experience. If you're not sure where to begin, we've laid out some helpful advice for finding something good and researched a few well-reviewed gaming TVs that should suit your needs today. Whether you use it for gaming or not, all good TVs are built on the same foundations.

For video games specifically, you want a TV with minimal input lag and fast motion response, with no blur or other unwanted artifacts behind quick-moving objects.

Although it might seem as though TVs are growing in size, good things still come in small packages. Plenty of manufacturers still support smaller TVs--models that range in size from 32-inches to 43-inches. These TVs can be the perfect fit for smaller living rooms or for bedrooms, guest rooms, and dorm rooms. While 65-inch TVs are more glamorous and 55-inch TVs are the most popular television size, the best 40-inch TVs can deliver great performance and desired features. There are plenty of cheap TVs out there that don't stand up, however.

Finding a suitable TV for your PlayStation or Xbox used to require a careful look at spec sheets. But that's not the case these days as the best TVs for gaming are usually the best TVs you can buy, period.

Apple's cheapest desktop computer has had a price cut and a power upgrade – making it one of the smallest, cheapest and most adaptable Macs yet. The Mac mini starts at £649 ($599/A$999) – £50 less than the 2020 model – and has Apple's latest M2 or M2 Pro chips as used in the MacBook Air and MacBook Pro to great effect. The tiny aluminium box is about the size of a hardback book, measuring just under 20cm each side and less than 4cm thick. It is easy to fit just about anywhere: on a desk, mounted under one, in a TV cabinet, on the back of the monitor, stuck to a wall – wherever you can reach with a power cable. Like a normal desktop PC you simply plug the Mac mini into a screen, keyboard and mouse, all of which can be bought with it at great expense – or you can use your existing gear. I connected an Asus 4K monitor and Logitech Bluetooth mouse and keyboard to the mini to set it up, using them during the length of the review without issue.
