Summary: There are a lot of portable Bluetooth speaker options available and I found the Divoom Bluetune Solo to be an excellent choice at a fantastic price. It comes in several attractive colors and even serves as a microphone.
I have tested a lot of portable Bluetooth speakers over the years, you can view a wrap up of many of them in this Gift Guide post. I don't travel without a portable speaker and think I just found my next traveling companion in the Divoom Bluetune Solo speaker.
You may think of turning the other way after seeing a speaker available for just $49.99, but stick around and check out my gallery and video walkthrough of this speaker. The sound is surprisingly good, the build quality is great, and you can use the Bluetune Solo as both a speaker and a speakerphone.
