【Near Mint Condition】Oyaide HPSC-35 1.5m

I purchased this new at e-earphone in Nihonbashi at the end of last year. I was curious about improving the sound quality of wireless headphones, but my ordinary ears couldn't tell the difference.
I only tried it at home for a few days and have no use for it, so I'm putting it up for sale.

No discounts or returns, thank you.
