## Long description

The Koss KPH30i headphones are wired on-ear headphones designed for clear audio during calls and music playback. They feature an open-air circumaural design with a frequency response of 15–25000 Hz and a 1.2 m cable for everyday portability. The grey head-band construction includes a patent-pending suspension system for adjustable, lightweight comfort and a durable cable with reinforced strain relief. An inline microphone and remote enable call handling and basic playback control when connected to compatible mobile devices.
Advantages
The KPH30i delivers balanced sound with smooth bass and clean treble across a wide frequency range, suitable for vocals and general music listening. The 60-ohm driver characteristics are optimized for use with portable players and smartphones. The integrated inline microphone and remote provide call and basic control functionality without adding bulk. The lightweight head-band and suspension system distribute pressure evenly for extended wear, while the reinforced cable termination improves durability for daily use.

How to use
Connect the 3.5 mm plug to the audio output of your smartphone, tablet or portable player. Position the adjustable head-band so the ear pads sit comfortably on the ears and allow the suspension to conform to head shape. Use the inline remote to answer or end calls and to control basic playback where supported by the connected device. Avoid excessive cable strain by routing the cable along your clothing and using the reinforced section near the plug as intended.
Usage recommendations
For optimal sound and microphone performance, use the Koss KPH30i with devices that support inline remote functions. Keep volume at moderate levels to preserve hearing and prevent driver fatigue. Store the headphones in a dry place and avoid sharp bends in the cable to extend lifespan.
