AV Adapter Mozos MA3525 2.5mm to 3.5mm Silver audio adapter

The Mozos MA3525 AV adapter converts a 2.5mm audio connector to a standard 3.5mm jack in a compact silver housing. This passive adapter provides a simple mechanical and electrical interface for connecting headsets, portable audio players, hands-free car kits or other devices with mismatched plug sizes. It supports unbalanced analog audio pass-through where the wiring polarity between devices matches, and its small form factor makes it convenient for travel and everyday carry.

Advantages

The adapter offers a straightforward, plug-and-play solution without the need for powered conversion or configuration. Its metal-finish silver casing adds basic mechanical protection for the connector while remaining lightweight. Because it is passive, there is no additional signal processing, preserving the source audio characteristics when used with compatible equipment. The compact size minimizes space on desks, in bags or in vehicle consoles.

Suitable for

• Connecting headsets with a 2.5mm plug to devices with a 3.5mm jack
• Adapting older mobile phones or two-way radios to modern audio equipment
• Using car audio inputs or portable speakers that accept 3.5mm connections
• Temporary or travel setups where a simple size adapter is required

Key specifications

• Connector types: 2.5mm male to 3.5mm female
• Function: Passive analog audio adapter for signal pass-through
• Housing finish: Silver metalized exterior
• Compatibility: Standard TRS/mono devices where wiring polarity matches
• Form factor: Compact, lightweight

How to use

Insert the 2.5mm plug of the headset or source cable into the adapter’s 2.5mm receptacle and then plug the adapter’s 3.5mm end into the target device’s audio jack. Ensure both devices use compatible wiring for left, right and ground contacts (TRS) to avoid incorrect channel mapping or missing audio. No power, drivers or configuration are required; ensure connections are firmly seated for reliable contact.

Usage recommendations

Use this passive adapter only with devices that share compatible wiring standards. Avoid forcing mismatched plugs and inspect connectors for dirt or damage before use. For critical audio applications or devices requiring microphone wiring or remote control pinouts, verify compatibility since the adapter provides only basic analog pass-through.
