Hosa YMM-108 — Headset/Mic Breakout Cable 3.5mm TRRS to Dual 3.5mm TRSF
YMM-108 Overview
The Hosa YMM-108 is a headset and microphone breakout cable designed to consolidate separate mic and headphone TRS outputs into a single 3.5mm TRRS connection. Built to the CTIA wiring standard, it ensures compatibility with all-in-one headsets used across broadcast, production, and field recording workflows. Oxygen-Free Copper (OFC) conductors and OFC spiral shielding deliver clean signal transfer with effective EMI and RFI rejection. This cable is a practical solution for engineers and technicians needing to interface dual-output devices with TRRS-input equipment.
Nickel-plated plugs provide rugged durability and efficient signal transfer, making the YMM-108 a reliable choice for repeated use in demanding environments.
