My only complaint is the thin wires on the headband which might be a disaster waiting to happen

Pro is more plastic and SRH840 seems more solid (though I don't like the exposed wires)

Seriously, like you would NOT want a child picking these up because they might rip the wire that connects the arch to the speaker on either side

The wires can become lodged in these pinch points, and the wires can be damaged.

One major drawback that I don't like is the exposed wires

But the exposed wiring makes me a bit nervous

Also worrisome is the exposed thin wire above both ear cups
