This is the WAGNUS. Zillion Sheep acqua. The ear hook area has yellowed, but I don't feel any major problems with hardening or use. There are no bends or rust on the 2-pin connectors. The 4.4mm plug also shows some age, but there are no bends. Please forgive any oversights. To prevent troubles such as switching items, returns and exchanges are not accepted. Please understand and purchase.
