Sennheiser RS195-U

Introduction to the Sennheiser RS-195U Headphones

The Sennheiser RS195-U is a wireless hi-fi headphone designed to offer a personalized listening experience, particularly suited for individuals with mild hearing loss. Here is a detailed overview of this innovative product.

Ergonomic Design for Optimal Comfort

The RS195-U features a sleek and elegant design, typical of the Sennheiser brand. Its adjustable headband and large circumaural faux leather ear cushions ensure a perfect fit and prolonged comfort, even after several hours of use. The ear cups fully encompass the ears, providing effective passive sound isolation.

The headphones are relatively lightweight (340g) for a model of this type, contributing to their comfort. Its robust construction with high-quality plastic ensures long-term durability. The closed-back design of the ear cups not only offers better isolation but also limits sound leakage to the outside.

Advanced Wireless Technology for Total Freedom

The RS195-U uses Sennheiser’s proprietary digital wireless audio transmission technology. This technology offers an impressive range of up to 100 meters in open space, allowing users to move freely around their home without signal loss.

Transmission occurs on the 2.4 GHz frequency band, ensuring crystal-clear audio quality without interference. The latency is remarkably low, around 60 milliseconds, preventing any noticeable lag between image and sound when watching movies or TV shows.

Features Tailored to Specific Hearing Needs

One of the standout features of the RS195-U is its ability to adapt to individual hearing needs. The headphones offer seven preset listening profiles, allowing users to adjust the frequency response to compensate for different types of mild hearing loss.

A “Speech” mode enhances dialogue intelligibility by emphasizing vocal frequencies and reducing background noise. The “Music” mode optimizes sound dynamics for more faithful music reproduction. A left/right balance control also allows fine-tuning of the volume for each ear.

Exceptional Sound Quality

Even without activating the hearing aid modes, the RS195-U delivers remarkable sound quality. The 17 mm dynamic drivers provide an extended frequency response from 17 Hz to 22 kHz, ensuring precise reproduction of bass, midrange, and treble.

The headphones stand out for their sound clarity and ability to reproduce subtle details in recordings. The bass is deep and well-defined, without overshadowing the midrange. The treble is smooth and precise, without excessive sibilance.

Versatile Transmitter Base

The TR 195 transmitter base that accompanies the headphones serves as both a charging station and a connection hub. It features analog (3.5 mm mini-jack) and digital (optical) audio inputs, allowing connection to a wide variety of audio sources: TVs, hi-fi systems, computers, etc.

The base also includes controls to adjust the different listening modes and hearing profiles. Its compact and elegant design easily fits into a living room or bedroom.

Generous Battery Life for Extended Listening Sessions

The RS195-U is powered by two rechargeable AAA batteries, provided with the headphones. The advertised battery life is approximately 18 hours, allowing users to enjoy the headphones for several days without needing to recharge.

The charging system is convenient: simply place the headphones on the base for automatic recharging. An intelligent energy management system optimizes battery life.
