How to connect Bluetooth Speaker to my Laptop?

Hi, I need a Bluetooth Speaker to connect with my laptop, it must be portable, wireless, waterproof and easy to handle.
Assuming your laptop has Bluetooth built in, just turn it on in settings,  follow bluetooth speaker directions for connecting to it  (usually pressing a button to enable devices to connect) then look for that device name in the list of bluetooth devices shown in the laptop bluetooth setings and select it.  It should then show as connected at which point any sound or music produced by the laptop should be heard on the bluetooth speaker.

Ultimate Ears has a nice selection of popular good sounding highly portable bluetooth speakers for reasonable price.

Many good ones out there depending on your need.    There is usually a tradeoff between size/portability and sound quality.   You have to decide what works best in your case there.
