New LG TONE Free T90S Earbuds with Dolby Atmos and Pure Graphene Drivers

LG Electronics introduced a new model in the company’s popular TONE Free true wireless earbuds with UV light sterilization in the charging case. The new TONE Free T90S flagship earbuds are a refined design that also offers a heightened listening experience thanks to new pure graphene drivers, ideal to match the Dolby Atmos experience with Dolby Head Tracking technology. The TONE Free T90S' are an even more comfortable Adaptive ANC design that adds all the latest most desirable features.

Always pushing different concepts into every product category, JLab introduced the new Work Buds ($79.99), a true wireless stereo concept that is intended to solve the sub-par microphone clarity problem during calls. The first time this is ever attempted in true wireless earbuds, the San Diego, CA-based added a a lightweight, detachable noise-canceling boom microphone. Revolutionary or simply awkward, now there is an option.

This article looks at the practical test and measurement of bone conduction technology, as used in product development for headsets and in-ear devices. It showcases new possibilities for manufacturers to better evaluate device performance, since no appropriate test equipment and methods were commercially available until now. The approach, complements a Head-and-Torso Simulator (HATS) with an actuator capable of generating structure-borne sound in the artificial ear. This way, a realistic simulation of the human structure-borne voice signal for in-ear headsets is possible.. This article was originally published in audioXpress, January 2023.

audioXpress February 2023 focuses on the small devices in the increasingly larger market of MEMS Microphones and Voice Pickup Sensors. The Market Update on this topic is complemented by Erica Yorga's article on the principles of Nureva's Unified Coverage Map. Ethan Winer offers the first of a primer on modern PC board design, there's a review of the Arylic Audio Up2Stream Amp V4 board, an inside story on how Crestron adopted AES67, and a High-Performance Tube Hybrid Preamp DIY project.

Great voice recognition can only start with great voice pickup. If cost is no object, of course you can build a great solution. Just use high-end voice activity detection, many-microphone beamforming and echo cancellation and you’ll have a premium product for high-end markets. But can you also satisfy mid-range markets with attractive pricing? This article discusses techniques to offer solutions for both markets.

Sony Electronics announced the SRS-NB10, an updated wireless neckband speaker design that allows users to seamlessly take conference calls, listen to music and walk around in total comfort. Designed to rest on the shoulders, the Sony NB10 features a full-range speaker response for a high quality personal sound field in a lightweight design for all-day wearing.

Vesper introduced the VA1200, which the company calls the world’s first analog piezoelectric voice accelerometer (a.k.a. bone conduction sensor). This low-power vibration sensor can be used in true wireless earbud designs to pick up the wearer’s own voice through bone conduction. Using the VA1200 in conjunction with a standard microphone and a sensor fusion solution, the application can achieve superior background and wind noise reduction. Vesper calls this combination OnePlusOne.
