Balanced Upgrade Cable for Fostex TH-Series Headphones
The Fostex ET-H3.0N7BL is a premium balanced headphone cable designed specifically for use with the TH900mk2, TH610, and TH909 models. This 3.0-meter cable provides a balanced audio connection for users with headphone amplifiers equipped with balanced XLR outputs, delivering improved channel separation, reduced noise, and enhanced audio fidelity. It’s an ideal upgrade for audiophiles and professionals seeking maximum performance from their Fostex headphones in high-resolution listening environments.

Designed for Balanced XLR Output on High-End Amps
With a male XLR connector at the termination point, the ET-H3.0N7BL is intended for use with balanced headphone amplifiers, DACs, and audio interfaces. Balanced signal paths offer lower noise floors and better dynamic range, especially beneficial in critical listening or studio monitoring setups. This cable gives your TH-series headphones the connection they need to fully benefit from balanced output designs.

Constructed with Ultra-Pure 7N Grade Oxygen-Free Copper
At the core of the ET-H3.0N7BL is 7N grade (99.99999%) oxygen-free copper—an ultra-pure conductor material selected for its ability to reduce signal loss and preserve high-frequency detail. This premium copper ensures transparency, tighter bass, and overall audio clarity, making it ideal for pairing with the TH900mk2’s signature reference sound profile or the TH610’s natural tuning.

Engineered for Secure and Clean Connections
The cable features rhodium-plated 2-pin connectors for a precise fit with Fostex headphones and a gold-plated XLR connector housed in durable aluminum alloy. This design ensures long-term mechanical reliability and minimal contact resistance. The high-quality plating enhances conductivity and protects against corrosion, delivering a consistent and clean signal path over time.

Generous 3-Meter Length Suited for Studio and Home Listening
With a total length of 3.0 meters, this cable provides ample reach for connecting to distant headphone amplifiers or studio gear without straining connectors or sacrificing mobility. It’s particularly useful in setups where equipment is rack-mounted or when listening from a seating position farther from the source gear.

Ideal for Audiophiles and Studio Professionals Seeking Clarity
Whether you’re an audiophile using a high-end balanced DAC or a professional tracking with Fostex headphones in the studio, the ET-H3.0N7BL offers a substantial sonic upgrade over standard unbalanced cables. The combination of ultra-pure copper, balanced XLR connectivity, and premium build materials make this a high-performance cable choice for anyone seeking true-to-source monitoring.
