Sennheiser MOMENTUM Sport semi-Open Earbuds Fuse Sports With Premium Sound

Available now, the all-new Sennheiser MOMENTUM Sport earbuds were developed for athletes and sports enthusiasts, and combine state-of-the-art integrated biometric sensors with superior sound quality.​ Unlike many other fitness-oriented products that basically focus on ingress protection and staying in place, the new Sennheiser MOMENTUM Sport earbuds are a premium ANC design that is intended to be both motivational and useful when combined with the leading tracking and training platforms.

Azoteq recently expanded its offering to the TWS market with the release of the IQS323. The IQS323 offers capacitive and inductive sensing as user interface and in-ear-detection, whilst the IQS7222A IC is a multifunctional capacitive, inductive, and Hall-effect sensor with additional temperature sensing for reference tracking. The IQS7222A is offered in a 1.62 x 1.62mm WLCSP and allows you to add a touch-and-swipe interface, wear detection, docking detection and your choice of an inductive waterproof button or the inductive force-sensing features.

Danish measurement microphone specialists GRAS Sound & Vibration, now a part of Axiometrix Solutions, announced two new microphones with SysCheck2 functionality allowing for remote-controlled health check of an entire measurement chain. The new microphones are the GRAS 246AE 1/2" CCP Free-field Standard SysCheck2 Microphone Set, and the GRAS 246AO 1/2" CCP Pressure Standard SysCheck2 Microphone Set, both featuring self-verification.

Azoteq recently released its second-generation four-in-one chip for earbuds. The IQS7222A IC is a multifunctional capacitive, inductive, and Hall-effect sensor with additional temperature sensing for reference tracking.

In the February 2015 issue of audioXpress, Mark Driedger discussed a tube power amplifier controller based on the Arduino open-source microcontroller. In this follow-up article, Mark Driedger explains how to use some of the Arduino’s untapped capabilities to incorporate the bias meter into the amplifier controller with virtually no additional hardware. A temperature sensor and over-temperature shut-down capability are also included. This article was originally published in audioXpress, May 2015.
