Know before you buy
The ARS100 is specifically engineered for the Acoustune HS1677SS and HS1697Ti headphones. It utilizes the Pentaconn Ear connector system, which is distinct from standard MMCX or 2-pin connectors.
The ARS100 features a hybrid 4-core construction of high-purity OFC and silver-plated OFC. This combination provides a more analytical, refined sound with improved clarity and a brighter, more defined low-frequency response compared to the stock ARC cables.
The Japanese PVC jacket is designed to minimize the 'stethoscope effect,' which is the audible noise caused by the cable rubbing against your clothing or body during movement. It ensures a quieter listening experience while maintaining cable flexibility.
The choice depends entirely on the balanced output port of your digital audio player or DAC/amp. The 2.5mm version (ARS132) is for devices with a 2.5mm balanced jack, while the 4.4mm version (ARS133) is for devices equipped with the larger 4.4mm Pentaconn balanced output.
Yes, Pentaconn Ear connectors are designed to be more stable and reliable than traditional connectors. They provide a secure, high-precision connection that is less prone to rotation or signal instability over time.
