There is no sound enhancement featue in this price segment.
I upgraded to Nokia 8 sirocco from Blackberry Dtek60.
Blackberry Dtek60 has Waves MaxxaAudio for tuning Bluetooth headphones.
But in nokia 8 sirocco there is stock equaliser.
That is very disappointed me. Even Nokia's old music player which comes with xpress music phones, N series phones is much better than now.
