Boxwave 3.5mm 4 Pole Male to 2.5mm Female Audio Adapter

3.5 mm to 2.5 mm audio adapter

This compact coupler converts a single 3.5 mm male plug into a 2.5 mm female socket. It lets you connect headsets, headphones or audio cables that use the smaller 2.5 mm jack to devices equipped with the larger 3.5 mm port. The adapter is designed for portable use and simple plug-and-play operation.

Zinc-alloy construction and straight connectors

The body is made from zinc alloy, giving a solid feel and durable finish for repeated insertion cycles. Both connectors are straight, so the adapter adds minimal bulk and sits flush against the device, reducing strain on the host socket. Its small footprint means it can stay attached to a cable or headset without snagging in a bag or pocket.

Check your device port and plug polarity

Verify that your source device provides a standard 3.5 mm TRRS or TRS output and that the 2.5 mm plug you intend to use matches the required pole configuration. The adapter does not convert microphone or inline-control signals beyond the physical connection, so headsets with proprietary pinouts may not function fully. Ensure the 2.5 mm cable or headset is compatible with the host equipment before ordering.
