Portable speaker

I recommend JBL flip 5 or JBL charge 5. But if you can buy two of the same models because you can link them together and get a stereo left and right sound, it is awesome. The "charge" series are cool because you can charge your phone with them. What I do is plug the Charge 5 into the truck to keep it charged, then run another cord from the Charge 5 into my phone, which keeps both phone and speaker charging.

 

I was looking into this as well. You can only have one ear covered with headphones right? So do guys listen to music / podcasts through those plantronics headsets they wear? I was thinking a regular speaker like the JBL units would be better.
