I bought ##Soundmagic es 18##(without mic) for rs 800 around in 2015 and used it for a year . I had done extensive amount of research before buying this product.
After using this earphone for a year I reordered this earphone with the mic variant and am currently using it.
Sound quality of this earphone is amazing for this price range. It has amazing bass which boosts the quality of sound.
The mids and the highs are very good but the lows are average. After burning the earphone(making earphone go through all range of frequencies) when the earphone is new enhances the quality of the sound.Sound reduction is very good.
The build quality is good but not great. After a year of use the ear buds were broken but it was an accident so nevermind. The wires are a bit tangly but manageable. It comes with extra ear buds which is a plus point .
