Sound Analysis

Lows

The C2 has decent sub-bass extension and the rumble is moderately quick. The bass note is being presented moderately without much authority. The decay is rather fast. Bass texture is decently smooth. The mid-bass has moderate quantity and the slam is not hard at all. The bass takes on a conservative approach.

Mids

The midrange is quite laid-back. The details retrieval is decent. The lower mids has a moderate amount of body to it and it is enough to tackle male vocals. The upper mids is not forward and there is a lack of crisp. Female vocals are expressed in a smooth manner. The control on the vocals is decent. The C2 is able to tackle male vocals better than female vocals.

Highs

The treble is extended decently and there is no sibilance and harshness. There is a moderate amount of air and there is lack of sparkle. The treble has a decent control. The definition is rather decent too. The nature ensures a fatigue-free listening.

Soundstage

The C2 has a decent soundstage for both the width and depth. The width is not very wide and it gets congested when tackling busier tracks. Layering and separation is decent.

Conclusion

The C2 is a decent iem with a polite sound. It is able to express the music in a smooth manner with decent details retrieval. In addition, it has an interesting design for the y-splitter acting as a microphone too. The Colarad C2 is good to use during commute and for picking up calls.
