Sennheiser Reintroduces HD 25 Headphones with New Redesigned Headband

For more than 30 years, the Sennheiser HD 25 headphones have been the professionals' choice for monitoring, field recording and DJing - as well as the favorite "light" headphones for many music enthusiasts. Now Sennheiser is launching an all-new HD 25 LIGHT model, which for the first time combines the sound signature of the original on-ear with a simpler headband design. By offering the same sought-after sound performance as the iconic classic, the new model provides an attractive entry into the HD 25 world.

For the January 2019 edition of Voice Coil magazine, Mike Klasco and Nora Wong have compiled a special Focus article on New Materials for Earphones and Headphones. For those looking to differentiate their new products, the two Menlo Scientific consultants provide a unique and valuable perspective on multiple possibilities and designs for drivers, materials for assemblies and enclosures, choices for headbands and ear cushions, signal processing, and even cables.

Voice Coil January 2019 is now available. This edition focuses on New Materials for Earphones and Headphones and also includes a valuable listing of Earphone and Headphone Manufacturers and a schedule of headphone-centric events for the year. In Acoustic Patents, James Croft looks at a new patent of a multilayer voice coil plate and flat speaker based on the same, while in this month's Test Bench Vance Dickason features a 1" compression driver from Radian Audio Engineering, and a 1" soft dome tweeter from Eminence. This is much more, now available in print and download.
