Sennheiser Now Shipping First Spectera WMAS Solutions

Officially unveiled to the world in September 2025, Sennheiser has announced that it will commence shipments of its Spectera wideband wireless ecosystem from April 25, 2025. Spectera is based on Wireless Multichannel Audio Systems (WMAS) broad bandwidth technology, offering the ability to densely pack many audio channels within a six to ten megahertz (MHz) radio frequency band, and meeting the regulatory goals around the globe for the use of available spectrum.

The Federal Communication Commission (FCC) approved a change in its regulation that now permits operation of Wireless Multichannel Audio Systems (WMAS) in the United States. WMAS is an advanced wireless microphone technology designed to meet the challenges of highly demanding live performance and studio applications. Sennheiser started development work on WMAS over ten years ago and, in August 2018, the company filed a Petition for Rulemaking with the FCC requesting a modification in the bandwidth limit specified for wireless microphones.

With live performances and touring gradually resuming after the pandemic, it’s time to resume products launches that have been on hold for some time. Sennheiser took lessons learned from its acclaimed Evolution Wireless IEM systems to now launch the new XS Wireless IEM system for musicians seeking to professionalize their shows by switching from floor wedges to wireless IEMs.

Halter Technical, a Los Angeles-based creator of headphones and headsets purposely built for the broadcast and video production industry, announced a new wireless design that takes lessons from the most recent Bluetooth TWS earbuds and hearing aids to create what the company calls the world’s smallest rechargeable miniature wireless in-ear monitor. The Microsone Discreet Audio Monitoring System introduces a new level of flexibility and control on set.
