NICEHCK Traceless (Traceless) In-Ear Earphones with 15.4mm Dynamic Driver, USB-C Wired A clone of the Sennheiser MX500, which inexplicably enjoys persistent popularity in China. The NICEHCK Traceless is one such example. The item for sale this time has a USB Type-C plug. It can be connected to Type-C compatible smartphones, tablets, laptops, etc. without a conversion plug. Please note that it cannot be connected to a 3.5mm jack. Also, although it is a Type-C connection, it does not have a microphone function, so it is only for listening to music. The colors are clear blue (left) + clear red (right). In-ear earphones are often difficult to distinguish between left and right, but even for those with presbyopia, this should make it easy to tell. Unopened, brand new, a set of sponge ear pads is included. I originally used the same product and bought this as a spare in case it broke. It hasn't broken, so I've decided to sell the spare. #InEar #IntraConcha #ChineseEarphones
