I was thinking of removing the listing and installing it after the holidays. It didn't sell, but thank you for the 11 likes (^ ^) The sound quality is not the current model's sharp, high-pitched sound, but rather a very resonant sound. However, you won't understand unless you try it. I wasn't planning on selling this, but I'm selling it because I haven't been using it much. To prevent any swapping, I will strictly adhere to a 3N (no returns, no refunds, no exchanges) transaction policy. If anyone is looking for this, please consider it. Considering the fees and shipping costs, I would appreciate it if you could refrain from asking for a discount.
