Sennheiser PC 2 Chat Mono Headset with Noise-Canceling Mic

The Sennheiser 504194 is a PC 2 Chat mono headset that gives you clear speech and steady listening comfort for every call, lesson, or game session. It is a straightforward tool for anyone who relies on a computer for daily communication, from remote workers and students to casual gamers who need to keep one ear on the room.

Speech comes through cleanly because the headset uses Sennheiser driver technology matched to a 32 Ohm impedance and a sound pressure level of 95 dB. These figures ensure that voices stay loud enough without harsh peaks, which helps when conversations stretch into long meetings or study groups.

The microphone sits on a flexible boom and uses passive noise cancellation to reduce the hum of fans, keyboard clicks, or nearby chatter. With a frequency response of 90 to 15,000 Hz, it captures the full range of human speech so the person on the other end hears you naturally, without the need to raise your voice.

A design that is light and rests on one ear lets you stay aware of your surroundings, which is handy if you need to monitor colleagues, family members, or doorbells while you talk. The foam ear pad and adjustable headband add comfort for people who wear a headset for many hours at a stretch.

Setup is immediate. Two standard 3.5 mm plugs connect to the microphone and headphone jacks on most desktop and laptop PCs, so there is no software to install and no batteries to charge. Just plug in, select the device in your audio settings, and start talking.

Durable construction backed by a two-year international warranty brings peace of mind to users who expect a headset to survive daily transport between home and office or frequent use in shared computer labs.
