Is this fake? I mean I can hear the same wobble even using a single earpiece, rather than both. That's not how binaural beats should work.
OP: Try again with a different device (tablet, laptop, etc) and/or make sure you aren't running some kind of filter or bass-booster.
Everyone else: cheap headphones are best! Fancy ones only muddy up the signal and create interference.
