This pair of Koss PLU in-ear bud PLUG KS168990 earphones deliver great sounds to your ears whilst blocking out external sounds.
These black ear buds give you isolation comparable to what you would expect with closed-style headphones. The Koss PLUG features a dynamic element that is positioned just outside the ear that is connected to a tubular port structure, inserted on a soft cushion that expands to fit your ear without the need for lots of different sized ear adaptors. This allows the PLUG to deliver high quality sounds to your ears.
The Koss PLU in-ear bud PLUG KS168990 earphones comes with a 1.2m cable.
