Anker’s Liberty 5 Pro earbuds get an AI-powered boost to noise reduction and calls

Anker’s Liberty Pro lineup gets AI-powered upgrades: the Liberty 5 Pro and Liberty 5 Pro Max use the Thus AI audio chip to boost noise reduction and voice clarity in noisy environments, with the Pro version at $169.99 and the Pro Max at $229.99; both offer up to 6.5 hours of listening (28 hours with the charging case), the Max adds AI-powered note-taking and the ability to record meetings without a phone via its larger 1.78-inch AMOLED display on the case, and the outside touchscreen lets you adjust ANC or invoke voice commands to control playback.

Open-ear champ for workouts? OpenFit Pro edges out OpenRun, but at a steep price

Testing Shokz OpenFit Pro against the OpenRun, Nico Arboleda finds the OpenFit Pro delivers top-tier audio quality and effective noise reduction for workouts with a secure, comfortable fit, but its $249 price and fiddly controls dampen its appeal for all-day use or very noisy outdoor cycling. The OpenRun remains cheaper and solid, so the “winner” depends on priorities: if audio quality and open-ear design justify the cost, OpenFit Pro; otherwise, a cheaper bone-conduction option may be the smarter pick.

Shokz OpenFit Pro: Open-Ear Noise-Reducing Earbuds Debut at CES 2026

The Shokz OpenFit Pro open-ear buds, priced at $249.95, feature a new noise reduction technology that significantly improves environmental noise dampening through a triple microphone array and adaptive algorithms, making them more effective for moderate noise environments like cafes and at home, though they still fall short of true active noise cancellation. The design remains bulky, and fit can be an issue, but the improved bass and additional features like Dolby Atmos support enhance their appeal for users who want awareness and decent sound quality during everyday activities.

Beta's Electric Aircraft Makes Historic Passenger Flight into NYC

Beta Technologies conducted a demonstration flight of its electric aircraft from the Hamptons to JFK, marking the first of its kind to land at a NYC airport. The flight showcases the potential for quieter, more sustainable air travel, with commercial certification expected in 2027. The company aims to replace noisy helicopters with electric planes for logistics, passenger transport, and military use, addressing rising noise complaints and environmental concerns in NYC.

NASA Develops Quiet Fan to Combat Space Station Noise

NASA has developed a "Quiet Space Fan" to reduce noise on spacecraft, addressing the constant hum from life support systems on the International Space Station. This innovation aims to improve communication, awareness of alarms, and reduce hearing loss risks for astronauts. The fan, initially developed at NASA's Glenn Research Center, is significantly quieter than commercial fans and will be shared with the industry for use in future commercial space stations.

"Silent Swimmers: The Stealthy Advantage of Fish Schools"

Researchers from Johns Hopkins University have discovered that fish swimming in schools not only provides protection from predators but also reduces their noise, making them more stealthy. Using a 3D model based on the common mackerel, the team found that synchronized tail flapping among fish cancels out each other's sound, effectively reducing the acoustic signature of a school of fish. This noise reduction also enhances their swimming performance, allowing them to swim faster while using less energy. The findings shed light on the evolutionary brilliance of fish schooling as a defense mechanism.

"Harnessing Quantum Dark States for Superior Noise Reduction"

Physicists have discovered a method to create highly entangled spin-squeezed states in multilevel atoms by harnessing superradiance inside an optical cavity, leading to the generation of dark states that are immune to superradiance and emit light at a much slower pace. This breakthrough could significantly enhance the precision of atomic clocks and quantum metrology, offering opportunities for quantum-enhanced measurements and potential applications in noise reduction.

"Surprising Health Benefits of Using Earplugs"

Earplugs offer more than just hearing protection, providing benefits such as noise reduction, better sleep, improved focus, and reduced sensory overload. They can help protect against hearing loss, reduce stress, and improve sleep quality, making them a convenient tool for everyday life. However, it's important to use earplugs safely, taking breaks to prevent wax buildup and being mindful of potential risks such as missing important sounds. Alternatives like earmuffs and noise-canceling headphones also offer options for protecting hearing and promoting peace of mind.

"NASA Unveils Supersonic Jet for NYC to London in 3.5 Hours"

NASA and Lockheed Martin have unveiled the X-59, a "quiet" supersonic aircraft designed to reduce the loud sonic booms of traditional supersonic flights to a gentle "thump." The 30-meter-long aircraft, part of NASA's Quesst mission, features a thin, tapered nose to break up shock waves and minimize noise. If successful, this technology could lead to a reconsideration of the ban on supersonic flights over land, potentially cutting travel time in half for commercial flights.

"Boost Your Quality of Life with These Simple Home Improvements"

Home renovations can significantly improve your quality of life beyond just adding value to your property. Enhancing natural light, reducing noise, installing ceiling fans, using a programmable thermostat, adding privacy fencing, relocating the laundry room, covering outdoor spaces, painting, and incorporating storage can all contribute to a more comfortable and enjoyable living environment. These improvements not only enhance the aesthetics of your home but also have a positive impact on mental and physical well-being.

Quantum Computing's Promising Advances: NIST's Toggle Switch, Natural Interaction, and Brain-Like Behavior

Scientists at the National Institute of Standards and Technology (NIST) have developed a "toggle switch" device for quantum computers that adjusts connections between qubits and a readout resonator, addressing challenges such as noise and reprogramming limitations. This device could lead to more flexible and accurate quantum processors, improving the ability to read outputs and reducing noise interference. The toggle switch can be flipped into different states to adjust the strength of connections, allowing qubits to interact and perform calculations, and retrieve results. The programmable toggle switch also enables the microwave pulses to control logic operations and makes the chip programmable. Further research aims to expand the number of qubits and resonators, potentially paving the way for powerful quantum computers capable of solving complex problems.
