Here is my biased review of earphones vs Earbuds. Please comment which you prefer.
1. Wearing earphones clearly reveals to people that you are doing something, ie listening to music. With Earbuds, this is less noticeable and people may try and talk to you and you would miss out.
2. Earphones do not need to be charged and overall consume little energy. Sure the headphone jack is oldschool so maybe the connection could be updated. Earbuds need an extra carry case or the battery is lost.
3. Earphones are easily wound up and there may be other ways to solve the messy wire problem. Earbuds need an extra carry case and it is a burden to carry around.
4. Earphones do not emit any radiation whereas earbuds use Bluetooth and this is microwave radiation (frequencies 2.4 GHz to 2.4835 GHz) which may heat up the eardrums and surrounding organic tissue and cause micro hotspots to occur when the microwaves reflect and produce standing waves. These micro hotspots are not likely to mutate dna and more likely to just destroy a few cells here and there.
I prefer earphones as they don't have the input lag like Bluetooth one's have, but the issue is when the phone's battery is low and you can't use earphones while charging the device.
