Sennheiser IE 600 Audiophile In-Ear Monitors

Selling my Sennheiser IE 600 wired IEMs. These are premium audiophile earphones that originally retailed for around $900, featuring 7 mm TrueResponse drivers, durable zirconium-alloy housings, detachable MMCX cables and a wide 4 Hz–46.5 kHz frequency response. Please read the condition details carefully: The earphones have an intermittent audio problem. Sometimes one side becomes so quiet that almost no sound comes through. Later, both sides may work perfectly normally, and then the other side may develop the same problem. I haven’t been able to identify the cause or find a reliable fix. This is my second pair; the original set was replaced directly by Sennheiser. I’ll include the replacement documentation shown in the photos. Sennheiser may be willing to help again, or someone familiar with IEM repair may be able to diagnose them. When both sides are working, they sound excellent: detailed and neutral, with fast, accurate bass and very low distortion. Sold strictly as-is because of the intermittent fault. The price reflects the issue. Includes everything shown in the photos. Local pickup in Marina del Rey. Comes with all original accessories.
