Features
Sound isolating technology -- The E5c's in ear design, using foam or flex sleeves, naturally blocks background noise. This allows lower listening volumes in loud environments. No batteries or extra equipment are needed for sound isolation.
Dual high-energy micro-speakers with extended frequency response and level attenuator -- The E5c's micro-speakers are of Shure's highest-quality construction. Each earphone contains dual micro-speakers, separating high- and low-frequency range; an in-line electronic crossover optimally separates these outputs, while a level attenuator allows comfortable listening levels for any high-output audio source. The E5c earphones provide the richest possible listening experience.
Personal fit kit -- Because every ear is different, E5c's earphones come with a pair of disposable foam sleeves, a pair of triple-flange sleeves, three pairs (small, medium, large) of flex sleeves, and three pairs (small, medium, large) ultra-soft flex sleeves to ensure a personalized fit.
Secure in ear design -- The soft, flexible sleeves in the Fit Kit gently contour the inside of the ear for a comfortable, secure fit.
Memory-fit earphone cables -- Once formed, the E5c's cables retain their shape around the ear, allowing for a more convenient, secure fit. The E5c's cables pass behind the ear -- out of sight and out of the way -- to provide a more comfortable, discreet fit.
Lightweight construction -- Weighing only 1.1 oz (31g), the E5c is lightweight and comfortable for any portable listening application.
Earphones carrying case -- The E5c comes with a stylish, compact carrying case. The case allows for an easy, tangle-free way to store your earphones.
