I purchased this previously from a certain flea market site. It appears to be a prize from a giveaway campaign held by Brise Audio on their official X (Twitter) account at the time. As I haven't used it much and it's been sitting at home, I'm putting it up for sale. The previous owner informed me that the wire is a rare cable using original wire not available in the existing product lineup. Regarding the sound characteristics, it has a solid low-end feel typical of Brise, while also providing a balanced and delicate sound across all frequencies, carefully reproducing each individual sound. I believe this is a very rare item with limited information available, so I'd like to offer it to the next owner at a price lower than what I paid. However, please understand that this is a used item. The items included are all shown in the photos. Returns, cancellations, and claims from the customer after the sale is finalized are not accepted. (I will keep photos of the item before shipping.) I may also be listing this on other sites, so I may have to cancel the sale depending on the timing. Thank you for your understanding. Please feel free to ask if you have any questions! Thank you. #WiredEarphones #Recable #effectAudio #Beataudio #wagnus #NOBUNAGALabs #final #onso #ELETECH #pwaudio
