Koss Sparkplug
Headphones are made with silicone earpieces that compress for insertion in the ear canal to expand for nose suppression. The Sparkplug's L-shaped design strengthens the wires running from each plug to the gold-plated mini-jack that plugs into an iPod or MP3 player. Although designed for noise suppression, Koss headphones could make hissing and crackling sounds that can be corrected if you follow these steps.
Instructions
1. Try a different set of headphones or earbuds to isolate the problem either to the Koss headphones or your listening device. The noise might not originate with the headphones.
2. Dial down the volume on your portable listening device to determine if the Koss headphones are being overpowered. Distortion will result if the volume on a personal audio device is raised beyond the response level of the headphone speakers.
3. Clean the mini-plug pin by brushing lightly with a file or fine-grit sandpaper and wiping it off with a cloth.
4. Press the mini plug firmly into the audio jack. Static and craqckling will occur if the pin is not pushed in the jack all the way.
5. Press the in-line mute button on the Koss Sparkplugs, then press it again to clear the switch. A loose connection, or misaligned switch parts, can cause headphone noise.
6. Gently adjust the plug in the audio jack to make a secure connection, then twist each of the two audio wires between a thumb and index finger to determine if the wires are stretched, cracked or loose. Any of these factors can cause noise in the earbuds. Twisting the audio wires gently in your fingers can sometimes restore the sound, but this improvement may not last long.
