1st Gen AirPods
I like the hooks, because I feel like I won't lose them
Feels more durable, and less fragile (in a good way)
I feel more comfortable with them being out of their case
I am comfortable with them being randomly in my pocket
Because they feel more durable, I may not need to carry the case with me
Active Noise Cancellation
Much smaller case (comfortably fits in my pocket)
Still feels like they can pop out of your ear
Because the stem is smaller than the AirPods, it feels less fragile
I used to own the first generation 2016 model.
Small pill shape means I can carry it around with me everywhere.
No tangled wires.
Easy switching between devices.
I don't mind the battery life, though some people seem to have problems with it.
The Apple headsets have always fit me fine. They don't come out when I'm running on the treadmill, or on the elliptical.
I sometimes only get one headset to connect.
