The WAHEY C1 Bluetooth speaker is a portable unit built to work with most any device from a smartphone to the Echo DOT.
Paring it with an Echo DOT or Fire TV stick also works very well.
Pairing to an Echo DOT or Fire Stick is done by using the Alexa App and going to Bluetooth settings.
The sound quality of the C1 is very good with deep Bass with little to no distortion. A quick overview and sound sample is at the bottom of the page.
The WAHEY C1 is a nice portable Bluetooth speaker with a great sound.
It is highly portable along with being water proof able to be used indoors or outside.
It is also has good compatibility and will work with most any Bluetooth device from a iPad to a Fire TV stick.
I am still testing the unit so far with good results and will update if anything changes.
As always be sure to read the reviews on Amazon or elsewhere to be sure a unit is a good fit for you.
