This type combines advantages of earbuds and in-ear headphones – depending on the environment and requirements of the user, they provide passive noise reduction for quality mode (conversation or active music listening) or they give control over the sound environment around user in comfort mode (stand by or background voice/music listening).
If you’ve been on an airplane in the last few years, you’ve probably seen the Bose QuietComfort noise-cancelling headphones before: they’re a favorite of regular travelers because they’re so good at keeping outside noise out. They’re comfortable, they sound incredible, and the noise cancellation is so impressive that you feel like you’re in your own personal bubble. These headphones are not cheap, but they’re definitely worth the money.
I will get to these today. Just imagine the sound you hear is a line stretching left to right, with bass at the left and treble to the right. Now the line is tilted toward the right so the bass is higher (stronger) and the treble lower (weaker). That’s an example of getting darker. It’s not a perfect analogy, since any complex combination of sounds or balance is possible, but in general when something sounds darker you’ll have less influence of the treble.
Magnetostriction headphones, sometimes sold under the label Bonephones, work by vibrating against the side of head, transmitting sound via bone conduction. This is particularly helpful in situations where the ears must be unobstructed, or for people who are deaf for reasons that don't affect the nervous apparatus of hearing. Magnetostriction headphones though, are limited in their fidelity compared to conventional headphones that rely on the normal workings of the ear. Additionally, in the early 1990s, a French company called Plasmasonics tried to market a plasma-ionisation headphone. There are no known functioning examples left.
However, most people won’t be able to hear the difference if they’re older than 24, have some form of noise-induced hearing loss, or are in the presence of outside noise. For this reason, we recommend wireless Bluetooth headphones for those commuting, or in noisy situations. If you’re listening primarily at home at the computer—get a set of wired headphones.
Active noise-cancelling headphones use a microphone, amplifier, and speaker to pick up, amplify, and play ambient noise in phase-reversed form; this to some extent cancels out unwanted noise from the environment without affecting the desired sound source, which is not picked up and reversed by the microphone. They require a power source, usually a battery, to drive their circuitry. Active noise cancelling headphones can attenuate ambient noise by 20 dB or more, but the active circuitry is mainly effective on constant sounds and at lower frequencies, rather than sharp sounds and voices. Some noise cancelling headphones are designed mainly to reduce low-frequency engine and travel noise in aircraft, trains, and automobiles, and are less effective in environments with other types of noise.
If you won’t compromise on sound quality—and you’re willing to pay for it—the Bang & Olufsen Beoplay E6 may be for you. It doesn’t come cheap, but the Beoplay E6 is one of the best portable wireless models we’ve ever tested. In addition to sound quality, it has design perks including magnets that clip the earpieces together (and automatically turn the headphones off) for easy transport, a braided cable for added durability, and water resistance, according to the manufacturer.
In-ear headphones are like earbuds but are an upgrade to them. These headphones fit into the wearer's ear canal and stay in place with the use of foam or rubber tips. These tips are available in custom sizes so they can fit each individual wearer. When a proper fit's achieved, in-ear headphones reduce outside noise and deliver sound quality at about the same level as over-ear and on-ear headphones.
