That decision is, indeed, up to Bose.
But should they choose to continue making a headphones that have a 1-in-N-million chance of exploding, this should be clearly indicated on every pair they sell.
So that their competitors who choose to invest in safety would be able to reap the fruit if their labor in the free market.
Also nobody has died so...
You are aware that wired headphones exist, right?
Also, quite a leap from "Bose shouldn't make headphones that explode while being used, like QC-35 II" to "if we ask for that, this will make all headphones heavy enough to cause neck problems and cost North of $600".
Self-exploding headphones were not a problem we had for most of the time headphones existed. There's no reason to introduce it, nor accept it.
>Also nobody has died so...
Oh, so someone has to die instead of merely being injured for you to care? That's hardly compassionate, but understandable.
How about we settle for the middle ground of the following being included with each pair:
"BOSE Quite Comfort QC 35 II. You might experience bodily injury during normal operation of this product. Also nobody has died, so..."
Lithium-ion are the best we have right now, and they "explode" (catch fire I think is more accurate) when damaged.
Do I want better battery chemistries that are more robust? Of course.
Am I going to hold this against Bose or any other battery-powered device manufacturer until we do? No.
