Backed by over 50 years of research in voice and acoustics, NTT has developed groundbreaking technologies to solve challenges in communication and audio. These innovations, now at the heart of nwm products, were created by NTT engineers who have shaped the future of sound for decades. As digital content continues to expand and our personal sound environments becomes more diverse, we saw potential in creating individualized acoustic spaces in which you can control your sounds to keep them private without compromising sound quality. This vision sparked the development of our current technologies, and our engineers will continue to push the boundaries of sound.
But the real driving force behind this evolution is you, the users and partners we meet through our journey. Your needs, your desires, and your vision inspires us to continue to innovate. Share your story and visions with us.
Let’s create seamless sounds for a seamless world.

The Science Behind the PSZ Technology.
NTT’s PSZ (Personalized Sound Zone) technology achieves the ultimate contradiction of containing your sounds to your ears without blocking your ears.
By applying the principle of sound waves, PSZ minimizes sound leakage by emitting the inverse phase wave of what is being played to essentially nullify the sounds from leaving the proximity of your ears. While traditional audio devices enclose speakers to prevent interference caused by inverse phase waves, PSZ takes the opposite approach, and uses these phase waves to contain your sound around your ears. This innovative approach encapsulates sound within a 360-degree zone around your ears, making it unlike a directional speaker product.
PSZ delivers clear sound without vibrations or pressures on your ears like bone conduction technology, and allows for a completely stress-free listening experience.
A Product Born from Countless Rounds of Trial and Error
Incorporating PSZ technology to earphones began by shrinking the speaker units to their smallest form, then faced the challenge of delivering powerful, yet high quality sounds while keeping sound leakage to a minimum.
Using inverse phase waves to cancel out sounds from leaking was an unprecedented concept and turning it into a product was no easy feat. We faced countless obstacles, from perfecting the placement and size of the sound ports to balancing the internal cavity structure for optimal acoustics. Every element, from phase alignment to hardware design, required extensive simulations and relentless fine-tuning. After hundreds of iterations, our sonority engineers, who are masters of acoustic design, brought this innovation to life.
The Future Shaped by PSZ.
Unlocking New Possibilities for Communication through Technology.
PSZ technology offers a revolutionary listening experience - an Open-Ear design with minimal sound leakage, which allows you to stay connected with the world around you while enjoying your choice of audio. Imagine listening to music on the way to work without risking safety, or engage in an audio-guided art tour without distracting others, or even effortlessly engaging in multinational conversations while traveling. PSZ makes these scenarios possible by enhancing your natural hearing with cutting-edge sound control technology.
Magic Focus Voice
Magic Focus Voice : clearly extracts your voice
Magic Focus Voice : clearly extracts your voice
NTT’s patented Magic Focus Voice (MFV) technology leverages the company’s deep knowledge of voice traits. By analyzing the time it takes for sound to reach two microphones the spatial area is identified, and Beamforming is used to distinguish the speakers’ voice to extract your voice clearly. Additionally, Spectral Filtering is applied to remove the ambient noises to ensure that only your voice is delivered.
Tackling New Challenges in the Age of Remote Work.
Delivering Crystal-Clear Voices, No Matter the Environment.
With remote work now a part of everyday life, joining conference calls from home, cafe, or places outside the office has become the norm. With this shift in workstyle, comes new challenges - background noises and environmental distractions disrupting communication. NTT began development of Magic Focus Voice technology in the early 2010’s and has continuously refined the technology through applications in cars and conference rooms. Years of development focused on solving the challenge of providing a clear sound regardless of the environment. This dedication has led to achieving this advanced technology. Recognizing the importance of clear voice communication in this modern, flexible working environment; NTT sonority applied the Magic Focus Voice technology to earphones to address the unique challenges pertaining to sound when working remote. With Magic Focus Voice technology, your voice is accurately isolated and the background noises are not picked up; ensuring that only your voice is heard when in an online meeting from home, office, or at a cafe for a seamless communication.
