Setup Instructions
Follow these steps to connect your Koss SB-45 Communication Stereophones to your device:
- Identify Connectors: The SB-45 features two independent 3.5mm audio jacks. One plug is for the headphones (typically green or with a headphone icon) and the other is for the microphone (typically pink or with a microphone icon).
- Connect Headphones: Insert the 3.5mm headphone jack into the audio output port of your computer or compatible device. This port is usually green or marked with a headphone symbol.
- Connect Microphone: Insert the 3.5mm microphone jack into the microphone input port of your computer or compatible device. This port is usually pink or marked with a microphone symbol.
- Adjust Headband: Place the stereophones on your head and adjust the headband for a comfortable and secure fit. The headband is designed to be durable and adjustable for various head sizes.
- Position Microphone: Adjust the flexible microphone boom so that the microphone is positioned near your mouth for optimal voice pickup. The microphone features Clear Voice Technology (CVT) for noise cancellation.
- System Settings: After connecting, you may need to configure your device's audio settings to select the Koss SB-45 as the default playback and recording device. Refer to your device's operating system manual for specific instructions on audio configuration.

Operating Instructions
Once connected, the Koss SB-45 is ready for use. Here are some operational guidelines:
- Audio Playback: Play audio from your connected device. Adjust the volume using your device's system volume controls. The SB-45 is designed to deliver premium sound across all volume levels.
- Microphone Usage: For voice communication, ensure your application (e.g., gaming chat, video conferencing software) is configured to use the SB-45 microphone. The Clear Voice Technology (CVT) microphone is designed to reduce background noise for clearer communication.
- Comfort Adjustment: The large, closed ear cups are designed for maximum isolation and comfort. If you experience discomfort during long sessions, slightly adjust the ear cups or headband position. The soft, leatherette ear cushions are intended to minimize pressure.
- Folding for Storage: When not in use, the SB-45 can be folded for compact storage. Gently fold the ear cups inwards towards the headband to reduce its size, making it convenient for transport in a briefcase or backpack.
Maintenance
Proper care will extend the life and performance of your Koss SB-45 Stereophones:
- Cleaning Ear Cushions: Gently wipe the leatherette ear cushions with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners. Ensure the cushions are dry before use.
- Cleaning Headband and Frame: Use a soft, dry cloth to wipe the headband and plastic frame. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying.
- Cable Care: Avoid sharp bends, twists, or excessive pulling on the audio cables. Store the cables neatly to prevent tangling and damage.
- Storage: When not in use, store the folded stereophones in a clean, dry place away from extreme temperatures and direct sunlight.
- Avoid Moisture: Do not expose the stereophones to water or excessive moisture. If they become wet, dry them thoroughly before storage or use.

If you encounter issues with your Koss SB-45 Stereophones, try the following solutions:
- No Sound from Headphones:
