Koss PortaPro

The first thing you'll notice about the PortaPros is that they look like something from the 1980s. That's because they are--Koss released these exact headphones in 1984 and they became so popular that Koss hasn't changed a thing for 23 years. These headphones retain the same design both internally and externally. The earcups are secured to your head by a thin steel headband that adjusts with two sliders that tighten and loosen the tension. Once you have them in place, the PortaPros are actually very comfortable--they're featherweight and additional cushions on top of the ear pads prevent the headset from slipping. The comfort level is taken a step further with what Koss calls their "Comfort Zone." This feature has three mechanical settings that let you adjust the tension of the earpiece against your head. The downside is that there's no way to lock the headband in place and the sliders like to get caught in your hair as you take them on and off. This also becomes a problem when you want to rest the headphones around your neck--the band immediately tightens up and practically strangles you.koss porta pro
