A Guide To Sennheiser Headphones


A leading brand in the headphone space, Sennheiser have been producing cans for decades. From high-end studio sets to affordable earbuds, they produce a vast range to suit a variety of needs.

With such a broad assortment and different styles available, it can be a little confusing to decide which pair would work best for you. So, to help you out, we’ll go through the major differences between headphone styles in addition to an overview of some great Sennheiser models we offer.

In-Ear, On-Ear, or Over-Ear?


Sennheiser-IE-100-Pro-In-Ear-MonitorsLike it sounds, these are a headphone design that fit straight into your ear. By far the lightest and most portable, these buds are often aimed at people on the move, whether that’s performing live with in-ear monitors or working out with sweat-resistant headphones. Their light profile makes any audio-on-the-go task a breeze.

With their size comes a compromise; they aren’t as capable of pushing as much air through as their on-ear and over-ear cousins. This means they lack the sonic detail that larger headphones provide, so if you’re looking for a high-grade audiophile experience these aren’t it. But it’s a small price to pay for exceptionally portable design.






Sennheiser-HD-25Another accurate name, on-ear headphones sit on top of your ear, rather than covering it all. This means they’re lighter in weight, less bulky than over-ear designs, and deliver more punch and open sounds than in-ear buds.

Their skinnier profile makes for great travelling headphones or live performances where you don’t want the isolation that over-ear designs can bring. As they don’t cover the whole ear, they’ll tend to let in more outside noise, letting you be more aware of your surroundings.

That said, there are models which are noise cancelling and isolating, but, usually, in order to achieve this, they have a tighter clamp to create a seal on your ears – potentially leading to some discomfort. In general, they’re less desirable for noise cancellation purely because they don’t block the whole ear or seal the ear canal.




Sennheiser-HD-400-PRO-Studio-Reference-HeadphonesSmall, bigger, biggest. Over-ear headphones are by far the biggest and most cumbersome of the cans, but they come with a larger feature set and extended performance capabilities. They’re built to cover your whole ear, which naturally isolates your audio more, even without noise cancellation.

Generally, these are the headphones you’ll get the best quality audio from thanks to the larger space that provides a more open sound and a more powerful array of drivers. These will gift a wider range of frequencies in combination with an extended sound stage, which is why in most professional settings, you’ll see over-ear style headphones.

Comfort is always a matter of personal preference, but over-ear designs frequently have the most padding for a soft feel and less fatigue during prolonged use. However, they’re more prone to feeling hot because of the reduced airflow around your ears.

Their size can make them ill-suited to any activity that requires movement, which is generally why they’re associated with stationary studio uses or DJ sets.


Open back or closed back?

The style of headphone isn’t the only thing to consider when making your purchase, it’s also important to acknowledge what kind of back they’ve got. Fortunately, like in-ear, on-ear, or over-ear names, it’s pretty easy to decipher what closed or open back might mean.

Open Back

Sennheiser-HD-650-Audiophile-Open-Dynamic-HeadphonesWhilst the name is self-explanatory, the way in which open back headphones affect sound is a little more complicated. Open back designs eschew a rear cover so that air can pass freely through the speaker driver, meaning there’s no seal over your ears. Consequently, sound can escape and enter the headphones, which leads to a clearer performance, with greater dynamics thanks to the absence of pressure build-up in the cups.

The drawback is that they aren’t great outside of quiet, controlled environments because outside noise will interfere with your sound – and people will be able to hear what you’re listening to. This means they’re ideal for studio settings where the low-noise background allows you to maximise their benefits to master your music.




Closed Back

Sennheiser-HD-25-Light-HeadphonesOn the other hand, closed back headphones seal the cup and your ear. This is far more effective at noise isolation, allowing you to block out unwanted background noise.

The potential compromise is more pressure build-up and a less dynamic sound. That said, you’ll be able to use them almost anywhere without interruption, particularly with sets that feature passive isolation.






Which one is right for you?

Now that we’ve got a basic grip of the different styles, we’ll look at some of the Sennheiser sets we offer and what they bring to you, whether that’s for casual listening or high-end production!
