NTT's patented technology-equipped "Mimispi" open-ear earphones up to 30% off! Special prices during nwm official store's "Mimispi SUMMER Campaign" and Amazon Prime Day

NTT Sonority Inc. (Headquarters: Shinjuku-ku, Tokyo; President and Representative Director: Koichi Takami; hereinafter referred to as "NTT Sonority") announced that its "Mimispi" series of open-ear earphones, which do not block the ears and are equipped with NTT's patented technology, will be available at special prices of up to 30% off. These earphones are part of "nwm (Noom)," the NTT group's first acoustic brand with the concept of "Co-being" rather than immersion. The special pricing will be offered during the "Mimispi SUMMER Campaign" held from 10:00 AM on July 7 (Tue.) at the nwm official store, and during the "Amazon Prime Day Early Access Sale" from 0:00 AM on July 7 (Tue.) to 11:59 PM on July 9 (Thu.), and the "Amazon Prime Day" from 0:00 AM on July 10 (Fri.) to 11:59 PM on July 13 (Mon.), both held on Amazon.

As extreme heat becomes more severe, the deterioration of the ear canal environment due to prolonged use of sealed earphones and headphones is drawing attention as a new summer challenge. This summer, the "Mimispi" earphones, which do not block the ears, will be more accessible with special prices on both the official store and Amazon. We propose "Mimispi" as a new listening habit for this summer.

Japan's Summer in the 40°C Era: nwm's "Mimispi" is Ideal for "Ear Warming" Countermeasures

With the progression of global warming, summer temperatures are rising year by year. The Japan Meteorological Agency has even introduced "extreme heat day" as a new forecast term for days exceeding 40°C, highlighting the severity of the heat. Along with this, the risk of "ear warming" – where the ear canal becomes hot and humid due to prolonged use of sealed earphones and headphones – is also increasing with these climate changes. If "ear warming" progresses, it can lead to discomfort and itching, and if symptoms persist, it may even lead to "ear fungus" or otitis externa.

A "Survey on Summer Earphone Usage and Ear Problems 2026" conducted by NTT Sonority in May revealed that approximately 60% (59.4%) of people experienced discomfort while using earphones or headphones in the summer. On the other hand, only 14.9% were conscious of ear care, making ears a blind spot for countermeasures.

Thermographic demonstrations focusing on the difference in shape also showed clear results. After approximately one hour of continuous wear, the ear canal temperature increased by about 0.9°C with canal-type earphones (other companies) that seal the ear, whereas "nwm DOTS," which do not block the ears, showed an increase of only about 0.2°C. In comparison, sealed headphones (other companies) showed an increase of about 1.8°C, while the open-ear type "nwm ONE" showed an increase of only about 0.6°C, resulting in a temperature difference of up to approximately three times around the ears.

"Mimispi," which does not block the ears, has a structure that maintains ventilation in the wearing area, making it difficult to trap heat and moisture. Since ambient sounds can be heard naturally, it is also suitable for outdoor safety during summer.

*Effects vary by individual and are subject to measurement conditions. Consult an ENT doctor if you have symptoms.

【Equipped Technologies】

Equipped with NTT's core sound-manipulating technologies, born from solving communication and connectivity challenges.

PSZ Technology*1

― Encloses sound, suppresses sound leakage

NTT's proprietary "PSZ (Personalized Sound Zone)" technology achieves the ultimate paradox. It utilizes the principle that when a waveform with a phase inverted by 180 degrees is superimposed on a sound wave (positive phase), the sound cancels out. Through proprietary hardware design, sound is contained within a specific area around the ear, suppressing sound leakage to the surroundings even without blocking the ear.

Magic Focus Voice*2

― Extracts only necessary sounds clearly

NTT's patented technology "Magic Focus Voice"*1,2, developed with a deep understanding of voice characteristics. It uses a hybrid processing of two technologies: "beamforming," which recognizes the acoustic space by utilizing the time difference of sound reaching two microphones to identify the speaker, and "spectral filter," which removes noise and extracts only the voice. It cuts out ambient noise and delivers only your "voice."

*1,2 These are technologies developed by NTT Computer & Data Science Laboratories.

*1 Equipped in all products.

*2 Equipped only in nwm ONE and nwm DOTS.
