Know before you buy
This adapter allows you to connect headphones or devices with a 3.5mm stereo plug into equipment that features a larger 6.3mm (1/4-inch) headphone jack.
Rhodium is known for its excellent conductivity and resistance to corrosion. Using it on the contact points ensures a stable, high-fidelity signal transfer that maintains the clarity of your audio.
The F63-S (R) is designed to be compact, measuring approximately 61mm in length. While it is more robust than standard plastic adapters due to its carbon fiber and metal construction, it remains lightweight enough to not cause strain on your equipment's jack.
No, this adapter is specifically designed for standard stereo (unbalanced) signals. It will not convert a balanced connection to a single-ended one.
Beyond its sleek aesthetic, the carbon fiber finish provides a durable, non-resonant housing that helps protect the internal components and maintain signal integrity.
