For the second time, the product sometimes did not work. (was: This product didn't work.)
I received the replacement on January 11 Japan Time.
However, no sound is output from the left side of the headphones depending on the degree to which the plug is inserted in the substitute.
Considering that defective products are sent twice in a row, it must be said that there is a problem in the design and manufacture of this product.
-- The following is a comment from last December.
I ordered on December 3rd and arrived at a house in Japan today (December 20th).
However, the headphones connected to this product can only be heard from the right side.
If I push the 2.5mm plug strongly, I can hear sound from the left side of the headphones.
I'm very sorry for waiting for the arrival of the product.
