A: Yes! Simply select the connector type that matches your devices (2.5mm, 3.5mm, or 4.4mm). The cable extends the connection between your source and headphones.

Q: Does the silver plating really improve sound quality?

A: Silver-plated OFC conductors offer lower resistance and better signal transmission compared to standard copper, resulting in clearer highs and improved detail retrieval for discerning listeners.

Q: Which length should I choose?

A: 0.5m is ideal for portable setups, 1.0m works well for desktop use, and 1.5m provides maximum flexibility for larger workstations or when devices are farther apart.

A: No - the soft PVC jacket and thoughtful 8-core braiding design resist tangling. The included leather tie and cable clip help keep everything organized when not in use.
