## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice Trumpet horn, with mild bass.
*by P***. on 6 March 2025*

Nice Trumpet horn, with some bass.Nice Horn from Hella !!Mind you if you are here for Creta style, they are not like that, rather they have mild bass (which I liked) sort of closer to Skoda style.Horn connector is 2 pin style, mine car was having coupler (connector style, also called Korean coupler) and for connection I have to side branch the wires.OEM Creta or Skoda Horns (will cost you ~2 times) but will have coupler built on them.

### ⭐⭐⭐⭐⭐ Good Product for your ride
*by R***A on 22 April 2025*

Loud horn Justified for the price charged

### ⭐⭐⭐⭐ Best Symphony Horn
*by A***A on 16 December 2024*

The media could not be loaded. Got it installed in my 2017 ALTO K10 which was already equipped with ROOTS dual horn but it sounded like OmniE🤡. So got it replaced and fitted these. Just Plug & Play, Hassle free installation.Consumes decent battery.Value for money at this price point.Performance is top notch & enough loudness for the pedestrians but symphony to ears.Chrome design makes it look sturdy. But it's not waterproof so watch out.
