Styled to compliment today’s popular MP3 players, the KEB7P earbud incorporates a dynamic element that delivers an impressive, full frequency response of 40Hz-20,000Hz. The intra-aural earbud design employs a soft, silicone housing and ear cushion that seals the sound in your ear to clearly reproduce every note of your favorite music. The KEB7P includes a compact, easy-to-store carrying case that will fit any lifestyle. Pocket-sized, it travels anywhere in a briefcase, backpack or purse. A four-foot straight cord features a 3.5 mm L-plug for improved reliability and durability and can be easily stored tangle-free in the carrying case. Built to last, the KEB7P is covered under Koss’ No-Questions-Asked Lifetime Warranty – the only warranty of its kind in the stereophone industry.
