I purchased this intending to use it for web conferences, but it was not compatible with my PC, so I am putting it up for sale. I only took it out of the box and connected it to my PC. I immediately noticed sound leakage, so I did not put it on my ears and did not use it. I carefully put it back in the box, but please understand that it has been stored by a non-professional. Please consider purchasing only if you are okay with this. I purchased it on Amazon for 2,562 yen including tax. I will consider lowering the price in the future.
