Audio Implements HDS-93 3.5 mm 4-conductor cord with resistor #329

Audio Implements HDS-93 Listening Cord

The Audio Implements HDS-93 is a 3.5 mm 4-conductor cord with resistor #329 built for listening only. It connects smartphones, tablets or any portable device with a 3.5 mm headphone jack to compatible receivers. The cable draws power directly from the host device so no external supply is needed. Its 4-conductor design blends two channels together for balanced stereo output.

Who This Suits and Who Should Look Elsewhere

This cord suits users who need a simple listening cable for the PO-15 receiver or similar channel-combining applications. It works on any channel and merges channels 1 and 2 into a single stereo feed. Buyers who need a microphone connection or a standard TRS cable without channel blending should look elsewhere. The resistor network is fixed and cannot be bypassed for other wiring schemes.

Key Specification — 4-Conductor Design

The single specification that decides fit is the 4-conductor layout with embedded resistor #329 that merges both audio channels. This wiring is required for the PO-15 receiver and similar listening-only setups. If your device expects a standard 3-conductor TRS or a 4-conductor TRRS with separate microphone contact, this cable will not function correctly. Verify the receiver wiring before purchase.
