nwm NTT Sonority Wired On-Ear Speakers (Earbuds) with PSZ Technology MWE001 Dark Brown

Balanced listening comfort: The open-ear speakers don't block the ears, so they allow you to clearly hear ambient sound and even your voice. The 12mm diameter drivers provide a natural listening comfort, similar to listening to background music, allowing a unique and balanced listening experience.
Minimizes sound leakage: Equipped with PSZ (Personalized Sound Zone) technology developed by NTT, Japan's leader in the telecommunications business, the technology minimizes sound leakage to the surroundings by containing sound to the ear, giving you the freedom to use devices in public spaces without the worry of disturbing your surroundings.
Perfect for those who frequently use online communication: The ears are open, so it's easy to speak without blocking the sound of your own voice. The built-in microphone also makes it ideal for remote work and online meetings.
Effortlessly talk to people nearby: Because the device doesn't block the ears, you can talk naturally to people around you even while listening to music. You no longer have to remove your device when paying at the cash register, and be alert of the sounds of approaching cars.
No fatigue from extended use: It's ultra-light, weighing at about 9g (without cables) and the stability of the ear-hook design reduces the stress from prolonged use.
