I bought the Sonilex Wireless Bluetooth Speaker from amazon.in for 63 INR but I don’t liked its build quality and its sound. I most disappointing quality of this speaker is that it has really weak connectivity and can be connected to unknown devices. I was using this speaker in a bus for listening to songs in the bus while going on a trip arranged by my tuition center. Someone in the bus connected his/her phone to the speaker by using some kind of app or something and played some inappropriate sounds and everyone in the bus started laughing on me since that thought that it started playing my hidden list, that moment was really awkward and also my teachers asked me afterwards about the sounds.
The range of this speaker is not good and it looses connection even if it is a few meters away from the connected device. I gives teared sound at some high frequencies and is not clear at times. Hence I will never recommend anyone to use this speaker personally.
