Koss Sporta Pro 164020 headphone

On-Ear Headphones for Active Use

The Koss Sporta Pro 164020 is a supra-aural headphone built for listeners who move between work and workouts. Its flexible headband switches between over-the-head and behind-the-head wear, so it fits under helmets, hats or hairstyles without pressure. Dynamic Mylar elements deliver a 15Hz-25KHz frequency response with less than .2% THD at 103dB sensitivity. A 3.5mm plug and four-foot oxygen-free copper cord connect directly to phones, laptops or portable players.

Check Compatibility Before Buying

Verify that your source device has a 3.5mm headphone jack or a suitable adapter, because the cable terminates in a straight 3.5mm connector only. The 60-ohm impedance works well with mobile outputs, but very low-voltage devices may not reach full volume. The supra-aural pads rest on the ears rather than around them, so listeners who prefer full circumaural isolation should note the different fit. No inline remote or microphone is included on the cable.

Upgrade from Basic Earbuds or Fixed-Band Portables

This model replaces disposable earbuds or rigid on-ear headphones that cannot adapt to headgear changes during commutes or sport. The behind-the-head option clears the crown for caps, hard hats or ponytails, while the collapsible design reduces bulk in a bag. The jump is worth it when you need Porta Pro-class sound with a headband that survives daily flexing and storage without snapping.
