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

Excellent standard of manufacture

This adapter is perfect for plugging into a 2.5mm Jack (small headphone socket) to create a 6.35mm / 1/4" jack (large headphone socket). Therefore this adapter is commonly used to enable headphones with a larger 6.35mm plug to be used with a 2.5mm jack (present on mobile phones and MP3 players etc)
