Hosa CMP-305 — 3.5mm TS to 1/4 in TS Mono Interconnect Cable
CMP-305 Overview
The Hosa CMP-305 is a 5-foot mono interconnect cable terminated with a 3.5mm TS connector on one end and a 1/4 in TS connector on the other, purpose-built for connecting mini mono phone jack devices to standard mono phone jack equipment. The cable is commonly deployed as a flash synchronization cable and in a range of professional and production environments requiring reliable mono signal routing. Construction centers on an Oxygen-Free Copper (OFC) conductor paired with an OFC spiral shield for signal integrity and interference rejection. This cable is a practical solution for audio engineers, photographers, and production technicians who need a dependable, low-noise mono interconnect.
The nickel-plated plugs provide rugged durability through repeated connection cycles, while the OFC spiral shield construction contributes to flexibility for use in tight cable runs or mobile setups.
