There are a few different magnetic products you can use to treat a headache.
Firstly there is the Magnetic Necklace which will help a headache and pains in the neck and shoulders. They will work even better along with a nice pair of magnetic earrings to give that extra boost because the magnets in the earrings are quite small but still have a good impact.
A Magnetic Pillow is useful for using while you sleep or sitting on a comfortable chair. There are other advantages to using magnetic pillows as they can be used to treat many areas of the body other than the head. You can use a magnetic pillow to sit on for hip pain, or behind your back for back pain. But you would not want to go shopping with one would you?
A Magnetic Headband is great for wearing around the house or while participating in some form of sporting activity such as tennis or jogging. It is not always practical to put on a Headband and wear it everywhere you go, such as to the Super Market a Preschool trip to pick up the kids. Sometimes you may want some pain relief while you are at work, or visiting someone that isn't as "out of place" as a headband.
Magnetic Earrings will help with a headache but are more focused on relieving stress and suppressing food intake for weight loss. The earrings are good to wear out, they look nice and will do a good job at treating your headache, but as I said before a necklace would give you that little bit more boost for your headache.
Plain Magnets are similar to magnetic earrings only they are just bare magnets with no clasps or decoration. The benefits of these are they are similar to earrings, but the magnets are much stronger and are held in place by using the magnetic force on each side of your lobe. The Plain Magnets would be OK to wear at home, but they don't look that attractive when worn outside of the house.
Magnetic necklaces are attractive and relatively inexpensive to buy, as long as you buy good quality from a trusted supplier.
