    Introduction

    Aroma Audio is a Hong Kong company that produces iems, dac and amps. For iems, they started out with the Witch Girl series which has a line-up that consists of the Witch Girl S, Witch Girl Pro and Witch Girl 12. Recently, they have launched a brand new series which is called Musical Box. In the Musical Box Series, there are the Early, Twins and Yao. In this review, I will be reviewing the Musical Box Twins.

The connectors have a black housing. The cable has a memory wire section that is enclosed in a opaque black heat shrink tube. It is not very flexible due to the metal inside that helps to form the shape. The chin slider is made up of a transparent tube and the y splitter is made of a soft rubber material with strain relief.
