Ever notice that when your earbud cable moves, you can hear it rustle in your ears? This cable noise is called microphonics, and there's a simple trick you can use to avoid it.
This is an old tip, but we've never featured it on Lifehacker. A lot of the noise depends on the quality of your cable, but to cut down on the noise, wrap the cable around the back of your ear, as shown above. You should get less of that rustling and thumping. CNET also notes that you can use a shirt clip to cut down on that noise, if you have one.
