Pros: Zero fatigue, nice mids and bass, looks nice, handmade
Cons: Veiled sound, slight bass bloat
The C-12s are the first IEM from Indian company, Signature Acoustics. The C-12s use a hand-made wooden housing and a great looking wooden Y-split and slider. At around $60 (AUD) they are a budget IEM which is impressive given their hand-made and all wood design, but the sound is just a little way off from being something to get excited about.
Overall, the sound is smooth, laid-back and very easy to listen to, but perhaps just a bit too warm and lacking in the air and extension needed to bring out the best of a wide range of genres. The bass and mids are good with an enjoyable balance and mostly lifelike timbre - they just need a little more air.
