It's the Small Cup
With this adapter you can feel free to use your 2.5mm terminated earphones. Although it's not the real balanced output, it's a very convenient way to most of the users.
A hallowed-out housing to pack them all
The outer shell of the TC25B adopts 316 stainless steel, by the way of hallowing out the inside and insulation processing, it's ready to pack the Type C plug, 2.5mm socket, circuit board and other elements in a perfect compact way. The strength of the stainless steel housing is reliable and secure enough for your daily use.
It couldn't be shorter
The TC25B is supposed to be placed at the bottom of the phone, so it's easy to get damaged if the adapter is too long. So we made it possible to reduce the distance between each component so as to make the adapter as short as possible.
2.5mm earphone socket
Support the headphones with 2.5mm interface. It doesn't have the function of balancing output. Sound quality is the same as the TC35B.
