There's a lot to consider when you're buying a new pair of headphones. But the most important is the design. This doesn't just dictate how they look, but the features on offer, how they feel when you wear them and how you'll use them day-to-day. We've selected both over-ear headphones and earbuds here, though we have separate guides to just the best wireless headphones of the on-head style, or the best wireless earbuds, if you want to narrow it down. In-ear headphones, also called earbuds or earphones, are usually the cheapest and easiest way to pump audio into your ears. They rest in or just outside the ear canal, creating a tight seal to keep air out and sound in. These are the most discreet designs you'll find, making them excellent for portability and the prime choice for athletes. Over-ear headphones generally provide fantastic richness and depth of sound, which allows listeners to pick apart the instruments and sounds much easier. Additionally, over-ear, or circumaural headphones, go around the ear and offer a generous amount of padding. Instead of enveloping your ears, on-ear headphones create a light, breathable seal around your ear. The noise isolation is less effective than in-ear or over-ear options. Some headphones don't go anywhere near your ears at all. Bone-conducting headphones send vibrations through your cheekbones and jaw up towards your inner ear, leaving your ears free. These headphones make great running headphones and swimming headphones. With wireless on-ear headphones and over-ear headphones, you simply lose the wire connecting them to your device – otherwise, they look pretty much the same as your regular pair of wired cans, and give you the noise-isolating prowess of over-ears without the need for cumbersome wires to connect to your device. True wireless earbuds have no cord whatsoever. For some, this means true freedom; for others, untethered true wireless means constant danger of losing their expensive audio kit down the drain – or terrible connections. The latter, at least, has changed now – thanks to advances in Bluetooth technology like aptX HD, the best true wireless earbuds have never sounded better.

We also have other guides for getting the most out of your headphones, including how to care for them – be sure to check out our how to clean your wireless earbuds walkthrough to make sure they're spick and span.
