I don't know anymore. It's hard to get any tech devices these days unless they're made locally. Ever since the pandemic scare, many items are scarce so, one has to buy what's available, instead of what one needs or wants.  However, when there is an abundance of choice, I chose the most sturdy metallic headphones I can find. even if they lack some features, since I know that they'll last longer than the plastic items being sold everywhere. I've broken so many of them that I realize that I need hardened headphones. Headphones that can take punishment.
