How much sound does this put out? I have a Boom2 that i love for doing yardwork. Throws the perfect amount of sound and sounds good, but would love something a bit smaller with better battery life.

I have the older version and use it all the time. The sound is surprisingly good and battery life is amazing.
How is it compared to Bose sound link for $49 on Walmart?
The wonderboom is more powerful, has better sound, more play time and USB C. It's a little bit bigger than the Bose but still very portable. Definitely worth $10 more
Don't think it's much different than previous versions. Just USB-C. However I use this thing ALL THE TIME. Easy decision for the $60 upgrade for me. No more micro.

Honestly I don't know there are much differences between 2, 3, and 4. This review about 3 doesn't mention much difference between 2 or 4. I just upgraded because I want USB-C and it's on sale. I'll donate the Wonderboom 2 to get a tax write off and save some additional money to make the upgrade. I use the device so much that the price is worth it to me. I easily use it a few hours a day.

Great price for a new product. $20 lower than I saw during Black Friday.
Going to buy this and then I'll be ready to upgrade my beta-max player.

Does this one sound good? Is "doubling up" still a bit of a pain in the ass?
