I bought the Boom 2 which is still firmly in its box. Should I get this instead or is Boom 2 just fine?

Boom 2 sounds leagues better, buts it's bigger, I had a soundcore boom 3i I didn't like it, my flip 7 which was smaller sounded better. My Charge 6 which is similar in size sounds leagues better. I think boom 3i is a miss from soundcore, boom 2 is amazing tho, I also own that speaker.

How is the Boom 2 compared to the Charge 6?

I would love to find this near me in Pennsylvania. Kinda hard to search for it I guess it's not listed which stores have them on their website...

I would avoid this brand at all costs now. They added a bunch of useless features including an AI assistant in their app. Read the recent reviews on the play store and comments about the app on Reddit.
