Portable 3, the latest gadget unveiled by AmTRAN Technology Company, is a NFC-enabled portable speaker, which can easily pair with mobile phone to play songs directly with just a tap. Pursuing a fancy industrial design to a limit, Portable 3 hides all the traditional I/O interfaces such as Micro USB and audio-input at its bottom on purpose. Users can slightly press product’s top letting its body move up slowly to reveal the hidden interfaces and hide them again vice versa. Overall, Portable 3 provides a remarkable audio experience with user-friendly interface and modern design for consumers to enjoy streamed music every single second!
