Summary: This is super cool! Actual Specs: Sensitivity: 104 db/mW Impedance: 32 ohm Max. Power input: 30mW 19-21000 Hz Frequency Range Its super Light weight compared to to other headphones The Lenght width are customisable and fits perfectly. Bass and Treble is good, Volume is also appreciable. The mic also works properly, but the sensitivity of the mic is not very high. So Youll have to hold it close and speak. But overall Id say its pretty good headphone for Rs 1400.
