Koss The Plug Wireless Earbuds, Black

The Koss The Plug Wireless are in-ear headphones that utilize a neckband-style design and connect to source devices via Bluetooth 4.2. Their primary feature is the use of memory foam cushions, which are engineered to expand and conform to the user's ear canal. This mechanism creates a secure fit and provides a degree of passive noise isolation from surrounding environmental sounds. The internal audio drivers are configured to reproduce a frequency range of 10 Hz to 20,000 Hz, covering the standard spectrum of audible sound.

Functionality is managed through an in-line remote on the connecting cable, which provides controls for music playback, volume adjustment, and call management. This unit also contains an integrated microphone with a noise-reduction feature intended to improve voice clarity during phone calls. The rechargeable internal battery supplies over six hours of continuous playback on a full charge. The package includes extra ear tips to accommodate different ear sizes and a clip to assist with cable management during use.
