NTT Sonority Corporation (Headquarters: Shinjuku-ku, Tokyo, President & CEO: Hiroshi Sakai, hereinafter referred to as "NTT Sonority") is pleased to announce that it is equipped with NTT technology from the NTT Group's first acoustic brand "nwm", which is based on the concept of "co-being" rather than immersion. We are pleased to announce the release of the open-ear neckband wireless ear speaker "nwm GO" that is perfect for outdoor activities and workouts. Pre-orders will be accepted from Saturday, March 1, 2025, and sales will begin on Tuesday, March 18, 2025. In addition to the official nwm store, it can be purchased at Amazon directly managed stores, Rakuten Ichiba directly managed stores, electronics mass retailers, etc.

■ Active daily life, vivid sound.

From "Ear Spy", a new product "nwm GO" was born to enhance activities.

In response to the changes in online meeting needs and communication created by the Corona disaster, nwm has developed a series of earphones that are equipped with NTT technology and do not block the ears. The feature of the ear spy is that even though it is an earphone, it has a sense of openness and realism like a speaker. In addition, NTT's unique "PSZ (Personalized Sound Zone) technology" suppresses sound leakage without blocking the ears, so the biggest point is that they can coexist while considering their surroundings. After going through wired for business use and completely wireless for multi-use, in 2024 we have announced the "nwm ONE," an overhead type that is unique in the history of open years in terms of design and sound production.

NWM, which continues to propose a new way of living with such ear spirits, has focused on active scenes such as outdoor activities and workouts. Spring is the season when people become more active with the beginning of a new life. There are more opportunities to incorporate leisure activities such as mountain climbing and camping, as well as exercise such as jogging and cycling. In such a scene, earphones are required to be able to enjoy safely and comfortably while listening to the surrounding sounds.

Therefore, nwm is pleased to announce the release of the "nwm GO," an activity model for ear spy optimized for active scenes. Targeting adults who enjoy an active lifestyle, this open-ear neckband wireless ear speaker is particular about wearing comfort, sound quality, and design. While maintaining the sound leakage suppression performance of PSZ technology, the newly developed driver achieves both high-quality sound and powerful audio experience. The neckband design is lightweight and flexible, and it is not easy to slip and get tired. It achieves IP55, which boasts the highest dustproof and waterproof performance among ear spores, does not worry about rain or stuffiness, and has a long battery life with up to 10 hours of playback.

nwm GO helps you communicate smoothly with your peers while staying safe without interfering with your performance or concentration. Make your active daily life sound vivid. As a motivational companion for your hobbies and habits, please enjoy open and satisfying listening.

Don't cover your ears, so you can rest assured.

Equipped with NTT's proprietary "PSZ technology", it can be used anywhere without hesitation.

Because it is an open ear, you can use it with peace of mind even if you wear it outdoors, because you can naturally hear the sound of traffic and the voices of people around you. For example, when talking to a friend or training partner, you don't have to pause the music or take off your earphones each time. NTT's proprietary PSZ technology suppresses sound leakage without blocking your ears, making it comfortable for those around you.

High-quality, powerful, and vivid audio experience.

Move your body, listen to your surroundings, and listen to your satisfaction.

In order to achieve clear and expansive listening even in active scenes, it is equipped with a newly developed driver that has been optimized. Although it is an open ear, it achieves powerful low frequencies and balanced mid and high frequencies. Since it is air conductive, it is easy to hear naturally, so there is no discomfort, and it is also a point that you do not get tired even if you listen for a long time. It also supports Auracast™ and multipoint, expanding the way you can enjoy and use it.

Lightweight and flexible neckband design.

Comfortable and stable because it weighs only 20g.

It has a stable fit that fits around the ears and neck, and does not slip even when moving strenuously, and does not interfere with performance or concentration. The neckband is made of light and soft silicone, and the speaker part is also stress-free because it is an ear-hook type that does not put a burden on the ears. There are no problems such as falling during use or getting caught in the body or surrounding objects, and you can wear it around your neck when not in use, so you don't have to worry about losing it.

Waterproof performance that does not worry about rain or stuffiness.

Up to 10 hours of playback for long activities.

It achieves IP55, which boasts the highest dustproof and waterproof performance in the Ear Spy series, and can be used without hesitation not only in sudden rain outdoors, but also in hard training at the gym. Battery life is up to 10 hours, and the battery lasts for long periods of time. It takes about 1 hour and 15 minutes to fully charge.

NWM's familiar round motif and solid design.

Coloring inspired by nature that is close to everyday life.

The speaker part has a round motif common to the ear spy series, and is finished in a simple and solid design to blend in with fashion. It is available in three colors: fog black (Fog = fog), Glacier white (Glacier = glacier), and soil beige (Soil = soil) inspired by nature.

PSZ Technology

― Confines sound and suppresses sound leakage

NTT's unique "PSZ (Personalized Sound Zone)" technology* balances the ultimate contradiction. The principle is that when a waveform with a 180-degree phase inverted (reverse phase) is superimposed on a certain sound wave (positive phase), the sound disappears. The unique hardware design allows the sound to stay in a certain area near the ear, so it suppresses sound leakage to the surroundings without blocking the ears.

* This technology was developed by NTT Computer & Data Science Laboratories.
