Just find some reviews on the web ?

My preference as a consumer, is that the batteries for the thing be
removable, *and* be a standard type. (Unlike with digital cameras,
where there are custom battery packs for each one.) If the battery
type was a standard, you could pack a spare set.
For the product on the left, I tried to find out the battery type,
and so far, it hasn't been mentioned as a "D" cell or anything.
It may be a fixed internal battery.
I would also listen to them in person. When it came time to purchase
computer speakers, one of the local computer stores had a relatively
large display area with speakers set up. And nothing there was worth
a penny - just crap. I would not want to buy and return, over and over
again, speakers sets until you get a good one. My favorite speakers
turned out to be a pair of speakers from a local "clearance" computer
store, that were only $20, but beat anything the other store had to offer
up to the $100 level. You can't really go by what other people are
hearing. If I'd relied on reviews, for the sound quality, I'd have
bought the wrong product.

Looking through some Newegg entries, you can find "tasteless" without
looking too hard. Fortunately, there are no reviews for this one.
If you took this to your work site, nobody is going to steal it
