3.5 mm Audio Adapters & Splitters — compact, durable solutions for splitting and converting headphone and linelevel signals Key benefits Simplifies connections: lets you split one 3.5 mm output into two 3.5 mm inputs or convert between mono and stereo connections without changing cables. Preserves signal quality: metalplated contacts and solid molded construction minimize contact resistance and help prevent audible loss. Durable, corrosionresistant construction: full molded plastic bodies and wearresistant, anticorrosive materials extend product life for regular use. Versatile and compact: small form factor fits standard 3.5 mm ports and is easy to carry in a bag or keep with equipment. What each adapter does (functions and specs) 3.5 mm mono plug to dual 3.5 mm mono jack adapter (double mono): splits one mono 3.5 mm plug into two mono 3.5 mm jacks so a single mono source can feed two mono inputs. 3.5 mm audio splitter: full molded plastic construction with metalplated contacts for secure, lowloss connections when splitting a 3.5 mm line or headphone output. Audio converter: made of environmentally friendly plastic that is wearresistant and anticorrosive, providing longterm durability for repeated insertions and removals. Double mono audio adapter (stereotodual): splits a 3.5 mm male stereo plug to dual 3.5 mm female connectors while maintaining channel separation and minimizing degradation of audio quality. Compatibility and performance Designed for standard 3.5 mm (1/8') headphone and line jacks used on smartphones, tablets, laptops, portable audio players, mixers, recorders and many consumer audio devices. Metalplated contacts improve connectivity and help resist oxidation; molded housings reduce strain on solder joints and cable entries. Practical use scenarios Share audio from a laptop or phone between two sets of headphones for collaborative listening or monitoring. Send a single stereo output to two separate devices (e.g., a recorder and a set of speakers) using the double mono adapter while preserving left/right channel separation. Split a mono linelevel signal so one source feeds two inputs on a small mixer or amplifier for simple routing in live or home studio setups. Basic specifications Connector size: 3.5 mm Types: mono plug to dual mono jack, stereo male to dual female (double mono), molded plastic splitter Material: full molded plastic body; metalplated contacts Properties: environmentally friendly plastic, wearresistant, anticorrosive, durable Note: Check device input/output types (mono vs. stereo) before use to ensure correct routing and expected channel behavior.
