Keep using a 2.5 mm headset with a 3.5 mm audio socket
- Reuse existing 2.5 mm headsets: Connect headsets or headphones with a 2.5 mm plug to 3.5 mm audio sockets.
- Stereo sound without compromise: 3-pole pin assignment for clean left/right channel transmission.
- Fast, tool-free use: Insert the 3.5 mm plug directly into the audio socket.
- Broad device compatibility: Works with playback devices with a 3.5 mm socket, e.g. MP3 players.
The adapter links a 2.5 mm jack socket to a 3.5 mm jack plug and enables the use of headsets or headphones with a 2.5 mm plug on devices with a 3.5 mm audio socket. The 3-pole pin assignment supports stereo playback without additional settings.
This is particularly helpful in on-site service deployments and installations when different connection standards meet. In existing infrastructures of companies and public institutions, the adapter quickly provides compatibility between existing headsets and current playback devices.
