Polk Audio UltraFit 3000

118 dB, 18 hz - 23 khz, 3.5 mm Performance, comfort and durability. These are the three things an active listener wants in their headphones. And only Polk’s new UltraFit Series of sports headphones combines these elements with world famous Polk high performance audio. We’ve reinvented the headphone to better suit listeners who want the best sound, in the most extreme situations, and don’t want to sacrifice performance (theirs, or their headphone’s). It’s a high bar, but worth the leap. And don’t worry, if you’re wearing UltraFits your headphones will stay right where they are when you make the leap!
