The Sennheiser CX 686G SPORTS In-Ear Headphones are designed to be durable and resistant to sweat, which makes them suitable for active on-the-go lifestyles and working out at the gym. The headphones deliver a full range frequency response of 18 to 20,000 Hz into a 20 ohm load. They feature an inline remote control with an omnidirectional microphone for managing media and making calls on most smartphones (including Android, Windows Mobile, and Blackberry). The Para-aramid-reinforced cable offers strength and durability with an oval design that helps reduce both tangles and cable noise. The headphones feature SteriTouch antimicrobial ear adapters in three internchangeable sizes (S/M/L) to provide a sealed in-ear design for improved blocking of outside noise.
