Purchased on Amazon in late March 2025. I haven't used them much, mainly just when riding my road bike. MINI is definitely the better fit for the average Japanese head size. Everything other than the main unit, including the case and charging cable, is unused. It's truly amazing, but I've used several of this series, and the sound quality is far superior to previous models. SHOKZ bone conduction headphones, black, with carrying case. - Brand: SHOKZ - Type: Bone conduction headphones - Accessories: Carrying case - Color: Black Thank you for looking.
