We know you want decent in-ear headphones but not at a price that costs the earth. That’s why Koss Sparkplug headphones are so good. Small, lightweight and designed for portable listening, these headphones manage to effectively isolate sound - so you hear your music and nothing else.

The best features on these headphones are the soft foam cushions – they can easily be pinched and twisted to fit into your ear and will then expand slowly to provide a custom fit inside your ear canal. What all this means is that the Koss Sparkplug in-ear headphones directs sound into the ear canal - improving sound isolation, enhancing deep bass and treble clarity, and eliminating most ambient noise too like car traffic.

In addition, the Sparkplug features a dynamic element for extended frequency response, replacement ear cushions and is finished with a white cord that compliments many MP3 players.
