So the first IEM from an Indian manufacturer has good performance and has a few headline features like a lovely brass case, wooden housings and excellent bass.
However, while the sound of the SA C12 is good the IEM market is so competitive these days that there are 100s of other earphones at this price range that are available.
The C12 is priced at Rs. 2,700/- which I believe is a good enough price considering the build, sound quality and accessories provided.
Some of its locally available competitors that I have at hand to compare are the Idance X104 which has even more prominent bass but is a rather slow paced IEM and lacks the wide soundstage that the C12 has. Detail retrieval is around the same, but the C12 is a clearly better rounded IEM.
The other IEM I have is the RHA M450i which is priced at 40 pounds and so is priced very similarly to the C12.
The RHA is a very different IEM to the C12. They are practically Ying and Yang. The RHA has much thinner notes and sounds on the colder side of neutral. The RHA has a very small and intimate soundstage and lacks the impact-full bass that the C12 has.
That said the RHA has almost scarily impressive imaging and instrument separation and has impeccable detail retrieval that matches IEMs priced much higher.
So in conclusion the C12 is a very competent IEM and has an easy to recommend sound as a warm sound generally works well across most genres and has few flaws that could spoil the overall listening experience and kudos to Signature Acoustics for taking the initiative to create India’s first IEM.
