Joggers, snowboarders, and other outdoor enthusiasts will delight in the Sony MDR-J20 headphones, as their contoured clips follow the curve of the ears to ensure a snug fit even when bouncing around. The headphones also feature a flexible ear hanger that reduces stress on the ear, along with an open-air design that lets in ambient sound without sacrificing the quality of the music. The latter function is particularly important when skateboarding or running, as users can listen for traffic noise and other audible threats. It's the audio, however, that matters to most listeners, and the MDR-J20 headphones deliver on that count, too. Each earpiece carries a powerful neodymium magnet that provides great sound at frequencies between 18 Hz and 22 kHz. Don't give in to poorly designed, bulky headphones that slow you down while exercising. The MDR-J20s, which weigh a mere 0.35 ounces, are a perfect fit.
