Active noise cancelling headphones are not for everyone and some people prefer an alternative. That is why we have been experimenting with small, portable white noise machines over the past couple of months and finally settled on the Hafei.
It is small enough to carry around and is powered via USB (not battery operated). But the sound quality and volume is still more than enough, with ten sound options and a timer function to switch off automatically.
