The MDR-AS50G active-style headphones from Sony combine all the comfort and noise isolation of in-ear headphones with the stability of behind-the-neck sports headphones. Ideal for use during workouts, the headphones have a lightweight and discreet design that provides maximum stability.
Three different sizes of in-ear tips allow you to find the most comfortable and secure fit, which also helps to block out ambient noise and improve bass response. The flexible behind-the-neck band provides added security to ensure that the headphones don't slip off. A unique cord adjuster on the band lets you position the single-sided cable in the best position for sports or workouts.
A detachable extension cable and clothing clip are provided, along with a hard carrying case for travel. Moisture guards allow moisture to pass around the headphones, while neodymium drivers provide terrific sound quality with a wide frequency response.
