Modern Wi-Fi routers often ship with multiple antennas—sometimes up to eight—because of a technology called MIMO (multiple-input, multiple-output), which allows several data streams to be handled simultaneously rather than one at a time. This shift away from single-antenna designs was driven by the explosion of internet-connected devices in homes and the growing demand for faster, more reliable connections.
Sony has released the WH-1000XM4C, a variant of its popular WH-1000XM4 headphones featuring a new color option and a revised sound profile. The core hardware and noise-cancelling performance remain largely unchanged from the original model, but Sony has tweaked the tuning to offer a different listening experience.
Apple has started taking preorders for its new AirPods 5 earbuds ahead of a September 18th launch, the same day as the Apple Watch Series 12, Ultra 4, and iPhone 18 Pro lineup. The lineup includes a $129 standard model that now includes active noise cancellation, a feature previously reserved for pricier variants, and a $149 upgraded version with wireless charging, longer battery life, and stem-based touch controls for volume.
Anker's Soundcore Liberty 5 Pro earbuds, praised for strong call quality and IP55-rated durability, have dropped to $149.99 at Amazon, Best Buy, and Anker's own store, down from their usual $169.99. The earbuds had held that price steadily since their May debut, even skipping discounts during Prime Day in June.
Apple introduced the AirPods 5 with a wireless charging case at its recent event, pricing them roughly $30 below the ANC-equipped AirPods 4. Hands-on impressions suggest the newer earbuds outperform their predecessor across the board despite the lower cost.
Apple unveiled the AirPods 5, an update to its entry-level earbuds line featuring a redesigned acoustic architecture that delivers 50 percent better noise reduction than the AirPods 4. The lineup keeps the same two-tier pricing structure: $129 without a wireless charging case and $149 with one, both arriving September 18.
Apple has released a new generation of AirPods that improves active noise cancellation but leaves out the camera-equipped design that had been rumored ahead of launch. The earbuds focus on incremental audio and performance upgrades rather than new hardware features like built-in cameras.
Portable power devices often list peak wattage on the box, but real-world performance drops as heat builds up during charging—especially in magnetic wireless chargers, where the induction coils sit in direct contact with the phone. For years manufacturers have relied on passive materials like graphite sheets and heat spreaders to manage that heat, but these can only slow warming, not stop it, once a compact enclosure hits its thermal ceiling.
A report outlines why using Apple CarPlay wirelessly can drain iPhone battery faster than a wired connection, and suggests fixes such as turning off the screen, enabling Low Power Mode, using a wireless charging pad, downloading media offline, and limiting GPS use. It also notes that keeping iOS updated can bring efficiency improvements to CarPlay itself.
Sony's WF-1000XM6 and WF-1000XM5 both retail at $330 but are currently priced $50 apart on Amazon, with the M6 at $298 and the M5 at $248. The newer M6 has a smaller, pill-shaped design and a new QN3e chip that improves sound quality, but its ear tips create fit issues that weaken noise cancellation, while the M5 handles call clarity and background noise suppression better.
Portable CarPlay screens typically cost between $50 and $150, offering a cheaper alternative to buying a new car with built-in infotainment. Buyers should weigh screen size (6 to 11 inches), resolution (ideally at least 1280x720), audio output options like Bluetooth, AUX or FM, and whether the unit supports wireless CarPlay rather than requiring a cable.
A review of wireless Android Auto examines how the cable-free setup pairs automatically once a car starts, freeing up cabin space and removing the hassle of plugging in a phone each trip. However, it notes that going wireless increases battery drain, can cause noticeable heat buildup on longer drives, and depends heavily on both phone hardware and vehicle compatibility, particularly in older cars.
