Comfortable calls with reduced sound leakage. Open-ear headphones for the left ear, perfect for customer service.

The PSZ100-L (PSZ100L) is an open-ear earphone with a hook designed for the left ear, manufactured by YAESU (Standard Horizon). It adopts NTT's patented technology "PSZ (Personalized Sound Zone)." This allows for reduced sound leakage to the surroundings while keeping communication between staff private. It is ideal for business communications in quiet indoor environments such as restaurants, hotels, reception areas, and retail customer service. It helps ensure that customers are less likely to overhear conversations, supporting smooth customer interactions. The open-ear design does not block the ears, allowing users to naturally hear customer voices and surrounding sounds even while wearing the earphones. With a compact and lightweight design, it reduces pressure on the ears, making it comfortable for extended wear. The ear hook type provides a stable fit, making it less likely to shift in dynamic environments. It features a coiled cord designed to prevent disconnection and tangling, making it easy to handle for professional use. This product is the same as the accessories included with the "SRS12 PKG (PSZ-L) BLACK." *For more details, please feel free to contact us.
