headphones interact more directly with your ears than speakers, so headphones that interact in a way that is accurate for one person might interact with another person in a way that is less accurate. And different people value different aspects of sound when they're determining what is a reference headphone for them.
Obviously you need a road bike, a gravel bike, a hard tail 29er, a full suspension 27.5 mid fat, and a fat bike, for you, each of the kids, and your wife.
Find a local bike shop, look at their hardtails. Ask the shop for recommendations. They'll carry 3-4 brands. You'll want the relationship with the shop unless you want to tinker with the bike yourself.
