Both of them have upsides and downsides. Neckband headsets are easy and convenient to use. You can carry them around your neck while traveling or doing any workouts. There is no chance of losing them as they are connected via a wire. They have bigger batteries with long battery life and good noise cancellation features too. On the other hand, earbuds will give you a tangle-free experience. However, they should be handled with care. You can easily lose them. Overall, I am keeping neckband headphones a few steps ahead.
