I am using Bosch Symphony Horns from last 6 months.
I have not faced any problem yet.
in your case,
1. Please check cable, these after market people use low quality cable. which might have detached from horn (happened with me, just one month after installing new horns)
2. no proper power supply. (Ask mechanic to check with OEM horns, just plug them if they are working means new horns are gone).
Honda City does not require relay, as It already got two horns power supply and support.
Honda city OEM horns are very weak,
only good for city ride. for highway you need powerful horns, OEM horns are not good for highway ride
here are few pictures
Bosch Symphony horns are directional and pointed, so they must be facing towards front,
mechanic was doing easy fixing by making them facing sides,
but I did tricks and made him to make it facing front
we used two pins, one is straight, but second one is L shape
because of two pins, the horn vibration is not going to body, those pins are eliminating that vibration.
