Belkin showcased a range of recently released Qi2.2 magnetic wireless chargers at IFA 2025, along with other charging accessories and wireless earbuds. Nestled in all of this were two products that immediately caught my eye: the Belkin UltraCharge Magnetic Charger 25W and the SoundForm USB-C Wired Earbuds with ANC.
I want to talk about that second product, because this is something that has been stuck in a tiny space in the back of my mind for years. I rarely actively seek out noise-canceling wired earbuds, and when I do, I’m always disappointed to find they barely exist. At first glance, there’s not much to Belkin’s SoundForm USB-C headphones: they’re white, with flat wires that terminate in somewhat chunky earbuds. The earbuds are water- and- sweat resistant, feature 12mm drivers (for comparison, Apple’s AirPods Pro use 11mm drivers). Belkin claims they have “rich sound and deep bass.”
I got to test them a little bit, and yes, they sound decent—they’re not tinny, not muffled, the sound is reasonably balanced, and they’ve got nice-sounding bass, though it won’t rattle your brain by any means. Also, the SoundForm USB-C Wired Earbuds seemed to avoid the kind of boxy sound that I’ve noticed with some Belkin wireless earbuds. The active noise-cancelling (ANC) is far from competing with that of the AirPods Pro 2, but it does drop the noise around you—it seemed like it had a hard time with a narrow band of mid-range sounds. Maybe that’s intentional, to let you hear when people are talking to you, but it’s a weird effect. The wired earbuds also have a transparency mode, or you can turn these modes off.
The reason Belkin’s new headphones can actually do ANC is that instead of an unpowered 3.5mm headphone jack, they use USB-C. Sure, that limits where you can use them, but it’s a fine trade-off versus ANC wireless earbuds that you have to recharge and whose non-replaceable batteries are doomed to give out.
Of course, USB-C plugs don’t always last forever—the little pieces that secure them in a port can wear out, making their connection loose and finicky—so there’s a chance these may not endure any longer than the tiny batteries in wireless earbuds, especially if you use them a lot. Belkin representative Jen Wei told me that the company doesn’t hear regular complaints from customers about its USB-C plugs doing this, and it’s true that some last longer than others, but it’s something to be aware of. Still, I’m glad to see Belkin trying this. The SoundForm USB-C Wired Earbuds with ANC will be available in October for $34.99.
Belkin isn’t the only one bringing back wired earbuds. Sony also announced its own IER-EX15C earbuds (sorry, “in-ear headphones”) at IFA 2025. No ANC in these, but they also connect via USB-C. They’re $30, but for another $5, Belkin’s SoundForm USB-C Wired Earbuds seem like the better deal to get ANC.
At a glance, the UltraCharge Magnetic Charger 25W is just a MagSafe-style charging puck, but thicker and with a ring-shaped kickstand that you can also use to stabilize your phone. Unlike the UltraCharge 3-in-1 Magnetic Charging Dock that Belkin released last month, product manager Laurelin Stuart-Smith told me at the booth that the standalone puck has a heatsink inside for passive cooling—magnetic charging generates a lot of excess heat, and the 25W power afforded by this charger’s use of the Qi2.2 standard will only make that worse.
The UltraCharge Magnetic Charger 25W will be available in November for $39.95.
There’s one more thing I want to nerd out about from Belkin’s booth: the BoostCharge Retractable Car Charger 75W. Its integrated USB-C cable extends 75cm (roughly 2.5 feet) and offers 60W charging. The device also has two ports (one USB-A and one USB-C) and Belkin says it actively optimizes power delivery when more than one thing is connected.
I’m always very skeptical about retractable cables, or just retractable things in general—I’ve just owned too many cheap ones whose springs give out, rendering them annoying and useless. I’m also always wary of integrated cables for the same USB-C plug wearing out. I can’t speak to how long the USB-C plug on this device will last, but retractable cables can be done well, and at least from the brief time I had tugging on Belkin’s new car charger’s USB-C cable, it felt pleasantly smooth, with none of the odd clunkiness that tells you This Thing Will Break Soon.
The BoostCharge Retractable Car Charger 75W will be available in the US in October for $29.99.

![IBM Crosses One of Computing’s Biggest Barriers With World’s First Sub-1 Nanometer Chip
In a major breakthrough, IBM revealed the world’s first semiconductor chip technology built on a sub-1 nanometer chipmaking process. For comparison, the process uses transistor features smaller than the width of a DNA strand, which measures about 2.5 nanometers across. The chip itself is about the size of a fingernail but holds almost 100 billion transistors, and the company expects it could enter markets as early as the next five years. In a statement released today, IBM said the new chip features nearly twice the density of its 2-nanometer chip, released in 2021. According to an accompanying technical report, the chip also demonstrated up to 70% greater energy efficiency than its predecessor. In designing the chip, researchers developed an “entirely new transistor architecture” called nanostack, which “vertically stacks and staggers transistors” to enable IBM’s 0.7-nanometer chip technology, IBM explained.

Credit: IBM “With our new nanostack architecture, we’re not just making smaller transistors,” Jay Gambetta, director of IBM Research, said in the statement. “We’re reinventing how chips are built to deliver dramatically more power and energy efficiency.”
Smaller and smaller Semiconductor chips enable things like computers, home appliances, communications, and transportation devices. In 1965, Intel co-founder Gordon Moore surmised that transistor capacities evolved at a predictable and consistent rate. Specifically, all things considered, the number of transistors on a semiconductor chip would double about every two years. For a while, the so-called Moore’s Law held rather well—until, that is, things hit a literal wall.
“Moore’s Law was never meant to last forever,” according to a blog post by the Massachusetts Institute of Technology’s (MIT) Computer Science and Artificial Intelligence Lab. “Transistors can only get so small and, eventually, the more permanent laws of physics get in the way.” That is, as companies try to cram more transistors into smaller chips, new advances in transistor technology take longer than two years, so Moore’s Law has been over since at least 2016, Charles Leiserson, a computer scientist at MIT, said in the blog. Accordingly, the issue now is to consider how improvements in chip performance fit into a longer-term picture, Willy Shih, an economist at Harvard Business School, said in an explainer.
Reaching atomic levels In that sense, IBM’s latest chip represents an inventive approach for bypassing the limits of physical scaling. Specifically, two wafers with nanosheet-style transistors are glued together like a sandwich to vertically stack two layers of transistors, and related technical assessments suggested that the wafer stacking was flexible and scalable enough to support real computation, Huiming Bu, vice president of IBM’s silicon technology research team, said in a press briefing on the chip.

The company’s goal is to enter production in the next five years, but there’s still work to be done. For instance, Bu pointed out that the team was still working on pathways to prevent thermal noise or integration into existing systems in the high-performance computing community. “From my perspective, I hope to see it be as successful as the 2-nanometer [chip] and become the industry platform,” Gambetta said during the briefing. “And as we see with AI and classical computing in general, we are only seeing more and more consumption.” #IBM #Crosses #Computings #Biggest #Barriers #Worlds #Sub1 #Nanometer #ChipIBM,Semiconductors,transistors IBM Crosses One of Computing’s Biggest Barriers With World’s First Sub-1 Nanometer Chip
