DJ headphones are enjoying a renaissance at the moment buoyed by the street smarts of the Monster/Beats range and a proliferation of cheap music-creation software on portable devices.

Now anyone can be a bedroom (or bathroom, or train, or elevator, or even club) DJ armed with just an iPhone and a $5 app. The dinky earbuds you get with your device can't even cut it for simply listening to music, so trying to check your new mix with them is just a joke.

Enter the Koss Pro DJ100 headphones, which cater to DJs on a budget while still offering many extra features. For example, the Pro DJ100s include a mono/stereo switch on the right earcup designed to give a full mix from one ear for monitoring purposes, DJ-style.

The headphones feature a foldable design, metallic cups (with plastic hinges), and a padded headband. A leatherette material lines the inside of the cups, but they don't completely engulf your ear the way more expensive cans like the Audio Technica ATH-M50s do. The Pro DJ100s are attached to an 8-foot coiled cord that lacks extra adornments like a microphone and remote for your smartphone, though these are featured in the Pro DJ200 step-up model.
