Finally, a 4.4mm 5-pole plug with excellent cost performance has arrived.

4.4mm 5-pole plug compatible with SONY WM-1 series, Sennheiser headphone amplifiers, etc. With an opening diameter of approximately 6.4 mm, it is also compatible with thicker cables such as 8-core braid.

Consideration is also given to durability and workability. Good compatibility with lead-free solder that requires high temperatures. We are particular about the shape of the crimping, and have also considered measures to prevent wire breakage, which is a concern when re-cabling.
