Synergistic Research, the US-based high-end audio accessory manufacturer, has announced the release of the “HT Carbon,” a sound quality improvement accessory designed for in-line connection with headphone and earphone cables.

Product Overview

The HT Carbon is a sound quality improvement accessory for headphones and earphones that incorporates Synergistic Research’s proprietary UEF (Unified Energy Field) filter technology. By connecting in-line with headphone or earphone cables, it eliminates high-frequency noise that accompanies audio signals.

Synergistic Research has developed UEF technology over many years through their cable and power-related products, earning recognition for high-frequency noise elimination and its resulting audio quality improvements.
