This is a set of SONY XBA-N3 and MUC-M12NB1. I am not considering selling them separately. I think this combination of XBA-N3 and KIMBER KABLE is perfect for those starting out with balanced connections. The XBA-N3 is in good condition and produces a great sound. The S size of the triple comfort ear tips that came with the XBA-N3 is missing, so I have included different ear tips. As a bonus, I will include SednaEarfit XELASTEC II (ear tips) with the XBA-N3. These are the semi-transparent ear tips attached to the XBA-N3 body in image 12. These ear tips fit better with body temperature. I forgot the size, but they fit snugly. I will also include a cap to protect the 4.4mm jack as a bonus. The MUC-M12NB1 has a slight connection issue. When connected to a DAP, the balance of sound between the left and right channels may be poor. This can be improved by slightly moving the connection. The symptoms mentioned above will disappear after being connected for a while. They appear as initial symptoms when connecting. I have used them for about 6 years, with about once a month use for the first 2 years, and hardly used them for the rest. I have stored them in a dark place and handled them with care. The box is also available, and most of the accessories are included. I am selling them because I haven't used them much and would like someone else to use them. Spotify is also starting to stream in lossless quality. I hope that the goodness of wired connections will be re-evaluated. Thank you.
