Headphones vs Earphones

Hey everyone, John here. This may seem like an obvious topic, but there are a lot of differences between headphones and earphones… some of which are not as obvious as you may think.

Headphones

Sennheiser HD820

Starting with the shape and size. Headphones, as the name suggests, fit on your head, and have a headband that sits on top of your head. At either side of the headband, you have the speaker housings or earcups. The earcups hold the speaker drivers, and are designed in one of two ways: on-ear and over-ear. On-ear headphones have the earcups sitting on the ear and tend to be smaller in size, making them ideal for portable use. Over-ear headphones are larger and have the earcups completely surround the ear. Because of this, they tend to be used mainly indoors or where there isn’t much movement needed.

Earphones

Earphones are a lot smaller, and sit in the ear or in the ear canal. There are three main types of earphones:

Earpods / Earbuds

The older earphone design, or newer earpods, rest in the ear without going into the ear canal. This fit means that you are less likely to create a good seal between the earphone and your ear, resulting in an open sound that can tend to be a bit bass light. This fit also means that they will not isolate sound very well, meaning you are more likely to hear what is going on around you and people nearby will be able to listen to your music. Not ideal for public transport, but liked by sports users as it can be useful to hear your surroundings.

In Ear Earphones

In-ear isolating earphones have a deeper fit and will go into the ear canal, they also have eartips installed. This not only helps to keep the earphones in place, they also help create a good seal which improves isolation and sound quality, especially bass performance. In-ear earphones are the most common fit, and there are two ways of wearing them depending on the design. Cable straight down, and cable over the ear. The cable-over-the-ear design tends to provide a more secure fit and deeper insertion into the ear canal. This way, you will benefit from better isolation. Still, a lot of people prefer the cable-straight-down design as they are easier to use.

A quick note on bass performance. It is very important to make sure that you achieve a good seal when using in-ear isolating earphones. If you do not do this, the main effect to the sound will be a loss of bass… and nobody wants that. When this happens, the sound can come across very tinny and flat, so make sure you try all of the supplied eartips to ensure you’re getting the best sound possible from your new earphones.

Custom In Ears

Lastly, you have custom in-ears. These earphones are customised to fit your ear specifically. This is the best way of achieving a perfect seal, which hugely improves isolation and sound quality. This is done by having a mould of your ear taken, and then used to make an earphone that perfectly fits the shape of your ear. This is a more expensive option and is currently only offered by a small number of manufacturers.

Sound

There is also a big difference between how headphones and earphones sound. I wouldn’t say that one is better than the other. The overall experience is different and people will favour one over the other.

Headphones tend to deliver a more natural listening experience. What I mean by this is that with the speakers being away from the ears, sound is delivered in a more natural way. With our ears playing a part in capturing the sound, similar to how we hear day to day. Headphones can also deliver a bigger or wider sound due to the size of the drivers used and them being away from our ears.

With the speakers being so close to the ear, or even inside the ear canal, the experience from earphones is very different and can take a while for some people to get used to. Due to the fit being so close to the ear, and much smaller speakers being used, earphones are capable of delivering a very high amount of clarity and detail. Sometimes this can be overwhelming, especially for those who have never used earphones before. The close fit also means that sound can come across narrower and feel like it is coming from inside the head when compared to a headphone.

Conclusion

Ultimately, it comes down to taste and how you want to listen to your music. Both headphones and earphones can be used in a large number of situations, and whether you prefer using headphones or earphones – there will be a model out there for you.

Noise Cancelling vs Sound Isolation

It’s easy to confuse the benefits of noise cancelling with sound isolating headphones. This is easily done as essentially they are both doing something similar but in very different ways. Because of this  you want to make sure you choose the right headphones for your situation – this article will clear things up for you.

Noise Cancelling

Noise cancelling headphones can reduce the amount of low frequency hum or ambient sounds reaching your ear drums. This can make it possible to listen to your music without having to raise the volume excessively or even help you get some good sleep on a long journey – they don’t cancel out all noise. They are useful for people who travel a lot, especially by plane as the engine noise can become a nuisance. These headphones use active noise control to cancel out low frequency noise so they will need power; usually using batteries or USB power.

Depending on the model of headphone, if the power runs out one of three things will happen:

  • The noise cancelling function will stop running but you will still get sound from the headphones.
  • The sound will completely cut off, you will need to change batteries/recharge to use the headphones.
  • The noise cancelling will stop running and if the speakers have high impedance (require more power) then the sound you get will be faint.

A good example here is the Sennheiser PXC550, they are a Bluetooth wireless headphone that feature active noise cancelling, these do however stop playing when the battery runs out.

Sound Isolation

Sound isolation is a term used for headphones that block out external noise and reduce the amount of sound leaking for others to hear passively (without power), this is achieved by their build quality and materials used. Most closed back headphones or in-ear isolating earphones do this, but some will do it better than others. Lots of things can improve isolation such as leather ear pads, a good in-ear seal, heavy clamping force (tight fit on the head), acoustic treatment (dampening) in the ear cups and even the shape and material of the driver housing.

A prime example being the Bowers & Wilkins P7 Wireless, these have no noise cancelling but for everyday use they block out enough outside noise, and when the battery runs out you can plug the audio cable in and continue listening

Summary

Noise cancelling is great in theory, and for long journeys on planes it can be very effective, however it does have its drawbacks. In solving one problem, it creates another, and this is noise and lack of dynamic range in some senses. The other thing to note about noise cancelling is it is only effective against constant background noise, and does not help with sudden loud noises.

So it has its uses, but for most people, especially those wanting the best sound, noise isolating headphones are the only logical choice. The company will have put time into tuning the housing to reduce resonance, along with experimenting with different pad materials, to bring you the best sound and isolate unwanted noise.
