It never ceases to amaze me how a few grand worth of farts like this can sound. This normally defies physics 🙂 . Sure, no hi-fi, but does anyone expect something like this? We're going to a party.
great sound
simple party mode and equalizer settings
He wants to let it "breathe" for a while after unpacking before it sounds better.

Worst speaker I've ever heard. The bass is completely artificial and at 70% volume it is impossible to listen to. The sound is completely dull. I'm coming back after 2 hours.

I compared 4 models and this one pleased me the least. The boombox has brilliant sound, but it is unsuitable for indoors and very large to carry. This one is a lot smaller than the boombox, but doesn't sound as good, but is comparable to the Charger 6, which is half the size, 2/3 the price, much more portable. I was expecting leaps and bounds of difference between the 3, but it wasn't as significant as between the Charger and the Boombox 3. There's worth the price, but for the party! Not home..: -)
volume and clarity of sound up to about 50% of power. Then the quality drops for me.
Definitely for outdoor use.
Still quite portable.
at volumes above 50% power, the ball loses bass and goes high.
It's not a backpacking speaker anymore.

On a scale of extremes, I'd give it a 4
IP rating
Even if it can connect to older speakers, it must be the source one, on the contrary I couldn't connect them

It's still a lot of money for a portable bt speaker, but with a large battery capacity, durability and enough sound for a large room or garden, it's an acceptable price/performance/quality ratio.
Price (currently on sale)
Great endurance (supposedly 24h)
Replaceable battery
Beautiful clear sound
Resilience
Renowned quality
The power rating is 100w, but it's not rms (60w)
He doesn't have a radio
