These are the smart devices that I have and my quick review after using them for a while. Hopefully if you are considering buying one this may help.


Sonos One
It is probably the best sounding smart speaker you ever need.

Best sounding with room tuning capability
Nice looking
Reasonable loud

It is expensive. RM1199 sold here.
Not smart in Malaysia. Supposed to be able to work with Alexa but only for a few selected countries and of course Malaysia is not one of them.
No Bluetooth
Can't play very high resolution music like dsd

Amazon Echo Show

Expensive for the capabilities especially so so screen resolution
You tube integration cranky
Sound below expectation for the price although ok

Amazon Echo Dot 2nd Gen
