There are a few points to note for the integrity of this pair of speakers, the 1st one is that it is portable , one could bring it anywhere when they go outdoors or even travel to another country.
The next one is that they do not need a power socket to power them, it runs on the device you connect it to.
As you may have noticed the speakers can be extended (look at the right speaker) and compressed (the left one) when compressed it is to allow user to use up lesser storage space in their bag or even pockets.
Quality / Reflection
I’ve actually tested this pair of speakers at a local audio store at causeway point. The sould quality putput is nowhere near compared to a real pair of speakers but that can’t be helped after all it is self-powered from the device you connect to. But these pair of speakers are DEFINITELY light and SMALL.
