Gold plated connectors - to ensure there is a high quality connection.

Excellent standard of manufacture

This adapter is perfect for plugging into a 3.5mm Jack (standard headphone socket like on ipods) to create a 2.5mm (small headphone socket). Therefore this adapter is commonly used to enable headphones with a smaller 2.5mm plug (phone headsets) to be used with a 3.5mm jack (present on ipods, MP3 players etc).
