How to Reduce Background Noise on Work Calls with a Wired Headset

Quick answer

To reduce background noise on work calls with a wired headset, start by positioning the microphone close to your mouth (about a finger's width away) and slightly off to the side to avoid plosives. Then, choose a headset with a noise-canceling microphone if possible, enable your call app's noise suppression, and minimize room noise at the source. A wired connection avoids Bluetooth compression and dropouts, giving you a stable, clear signal.

Background noise on work calls is more than an annoyance; it can make you sound unprofessional and derail the conversation. Whether you work from a home office, a shared space, or a busy office, a wired headset with a well-positioned microphone is one of the most reliable ways to keep your voice front and center.

This guide walks through practical steps to reduce background noise using a wired headset. You'll learn how to position the mic, adjust software settings, and make simple room changes that add up to clearer work calls. No expensive gear required—just a few habits and the right headset.

Why a wired headset helps with background noise

Wired headsets transmit audio directly through a cable, avoiding the compression and potential dropouts of Bluetooth. That means your voice arrives at the other end with less processing, and any noise-canceling microphone can do its job without fighting a wireless codec. For work calls where clarity matters, a wired connection is often the more dependable choice.

Many wired communication headsets, like the Koss CS195 USB, are designed for office and conference use. The CS195 USB features a lightweight, single-sided design that lets you monitor the outside world while staying connected—useful if you need to hear colleagues or your surroundings. Its microphone is built for speech, so it picks up your voice more accurately than a laptop's built-in mic.

• A wired headset avoids Bluetooth latency and compression, which can muddy voice quality.
• Single-sided designs like the CS195 USB keep one ear open to your environment, which can help you modulate your own volume.

Step 1: Position the microphone correctly

Microphone placement is the single most effective way to reduce background noise. Aim for the mic to sit about a finger's width from your mouth, slightly to the side so you're not breathing directly into it. This position maximizes your voice pickup while minimizing room noise. If the mic is too far away, you'll sound distant and the headset may boost gain to compensate, amplifying background hum.

Check your headset's manual for specific guidance. On the Koss CS195 USB, the boom microphone is adjustable; bend it so the tip points toward the corner of your mouth, not directly in front. Avoid touching the mic while speaking, as that creates handling noise.

• Common mistake: placing the mic directly in front of your mouth, which causes popping on 'p' and 'b' sounds.
• Checkpoint: record a quick test in your call app and listen for clarity—adjust until your voice is loud and clear without hiss.

Step 2: Choose the right headset for your environment

Not all wired headsets are equal when it comes to noise. If you work in a noisy environment, look for a headset with a noise-canceling microphone. The Koss CS195 USB is a communication headset designed for office, language learning, and internet calls; its mic is optimized for speech, though the catalog does not specify active noise cancellation. For very loud rooms, you may need a headset with a more directional mic or a boom that can be positioned very close.

For personal listening and calls, the Koss CL3i earbuds include an in-line OneTouch remote for call and music control. While not a dedicated communication headset, they can work for occasional calls if your device has a compatible jack. However, earbud mics often pick up more ambient noise than a boom mic, so they're best in quieter settings.

• If you take calls all day, invest in a dedicated communication headset with a boom mic.
• For occasional calls, earbuds with an in-line mic can suffice, but expect more background pickup.

Step 3: Adjust software noise suppression

Most call applications—Zoom, Teams, Google Meet—include built-in noise suppression. Turn it on and set it to a moderate level. High suppression can make your voice sound robotic or cut out when you pause, while low suppression lets more background through. Test each setting with a colleague or use the app's test call feature.

In Windows, you can also adjust microphone levels and enable exclusive mode to prevent other apps from grabbing the mic. On macOS, check the input volume in System Settings. Keep your headset selected as the input device; sometimes plugging in a USB headset automatically switches the default, but not always.

• Common mistake: leaving noise suppression off and relying solely on the mic.
• Checkpoint: after changing settings, make a test recording to confirm your voice is natural and background noise is reduced.

Step 4: Reduce noise at the source

Even the best headset can't eliminate all noise if your room is loud. Close windows and doors, turn off fans or air conditioning if possible, and place your desk away from high-traffic areas. Soft furnishings—rugs, curtains, bookshelves—help absorb echo. If you can't move, a simple moving blanket hung behind you can reduce reflections.

For keyboard and mouse clicks, consider a quieter keyboard or a desk mat. If you share space with others, use a sign or a polite signal to indicate you're on a call. These small changes make a big difference in how you sound.

• Common mistake: ignoring HVAC hum, which can be picked up as a low rumble.
• Checkpoint: listen for background noise during a silent moment in your test call—if you hear it, so will your colleagues.

Step 5: Maintain your headset for consistent performance

Over time, ear cushions and microphone windscreens can wear out, affecting both comfort and audio quality. Replace worn cushions to maintain a good seal and consistent microphone distance. For the Koss ESP/950 Electrostatic Headphone, replacement ear cushions are available; keeping them fresh ensures optimal performance. While the ESP/950 is not a communication headset, the principle applies: clean, well-maintained gear performs better.

Check cables for fraying and replace if needed. A damaged cable can introduce static or intermittent connections, which sound like noise to your call participants. Store your headset properly when not in use to prevent damage.

• Inspect ear cushions and mic windscreen every few months.
• Replace damaged cables promptly to avoid crackling or dropouts.

Your step-by-step noise reduction checklist

1. Position the mic: Place the microphone a finger's width from your mouth, slightly to the side. Bend the boom so it points at the corner of your mouth. Checkpoint: record a test and listen for clarity—adjust until your voice is loud and clear without hiss.
2. Pick the right headset: For frequent calls, use a communication headset like the Koss CS195 USB with a boom mic. For occasional calls, earbuds with an in-line mic can work in quiet spaces. Checkpoint: if you're in a noisy room, a boom mic is non-negotiable.
3. Enable software noise suppression: Turn on noise suppression in your call app and set it to a moderate level. Test each setting to avoid robotic voice or cutouts. Checkpoint: make a test call to confirm your voice sounds natural and background noise is reduced.
4. Quiet the room: Close windows and doors, turn off fans, and add soft furnishings to absorb echo. Move your desk away from high-traffic areas. Checkpoint: during a silent moment in a test call, if you hear background noise, so will your colleagues.
5. Maintain your gear: Replace worn ear cushions and damaged cables. Clean the microphone windscreen gently. Checkpoint: inspect your headset monthly and replace parts as needed to keep audio clean.
