Open Back Headphones Vs IEMs

IEMs (in-ear monitors) are high-quality earbuds that sit in your ear and block out background noise. Over-ear headphones are bulkier, but they can deliver better sound quality and are usually more comfortable to wear for longer periods. To evaluate the two more effectively, we will have to consider some factors, such as sound quality, sound isolation, price, additional hardware, and comfort. 


The fundamental advantage of open-back headphones is their ability to provide a large soundstage, which helps with the stereo image. This means that when you use open-back headphones, sounds become clearer and easier to locate.

Because we’re comparing tiny drivers against massive full-sized headphones drivers, IEMs can’t beat open-back headphones. 


Many gamers and audiophiles know that open-back headphones are pricey. By comparison, nice IEMs that are affordable and sound substantially better than anything in their price range, such as the KZ ZS10 Pro, may be found.

Sound Isolation

Using open-back headphones to listen to music in a noisy environment can be a nightmare. This also works the other way around, because open-back headphones leak sound readily, so if you play at excessive volumes, you may bother those near you.

In such cases, opting for a pair of IEMs solves both difficulties because they naturally isolate sound and do not bleed at all. This is a significant victory for IEM.


Because open-back headphones are larger and thicker, you need to ensure that the clamping force, ear cup size, and cushioning are sufficient. However, with IEMs, none of these factors matter.

What Are Open Back And Closed-Back Headphones?

Open Back Headphones

Headphones with open-back earcups allow air to flow through the back of the earcups (facing outwards). The driver’s sound can travel in two directions: directly into your ear and out into the surrounding area. 


  • Enhanced airflow
  • Image in stereo
  • Ear fatigue is reduced
  • clear sound delivery


  • Expensive
  • Leaking sound into the environment
  • isolating noise
  • There are fewer models available.

Closed-Back Headphones

Closed-back headphones have an airtight seal around the back of the earcups (facing outwards). The sound is encased and sealed inside each headphone. Unless you’re listening with the volume turned up loud, no sound will escape the Headphone.


  • Isolation from the surrounding noise
  • Low-end extension
  • A completely immersive listening experience
  • There is very little sound leaking


  • It is less breathable.
  • The impact of proximity
  • Image in Stereo

How Do Open Back Headphones Work?

Open Back Or Closed-Back Headphones For Music Production

Music production, mastering, mixing, and other basic audio engineering that requires headphones need an acoustic delivery. The best option, in this case, is to go for open-back headphones. This is because of its unfettered sound processing and capacity to generate acoustic sound, which means the sound is as natural as possible.


1. Are IEMs better than earbuds? Do they work the same or different?

IEMs essentially operate as earplugs once a suitable seal is formed, greatly reducing ambient noise. However, earbuds lie on the outer ear and do not seal off the ear canal, allowing a lot of ambient noise through. IEMs are worn directly within the ear canal and provide substantially better noise isolation.

Also, note that IEMs are made up of a pair of driver chambers topped with silicon or foam ear tips that fit directly into your ear canals. On the other hand, earphones are the classic earbud-shaped items that sit at the entrance of your outer ears.

2. Where are IEMs mostly used?

  •  Audio professionals use them for live monitoring and studio production. IEMs enable musicians to hear themselves as well as their unique mix while shutting out competing vocals and noises.
  • Performers also use them on stage.
  • Audiophiles and music enthusiasts use them as a handy method to listen to music.

3. Is a DAC worth it for IEMs?

In most cases, the answer will be no. A DAC won’t help you much unless you have jittering or hissing in your audio. It is typically preferable to spend the additional money you would have spent on a DAC on nicer headphones.


In the end, it all comes down to your desired preference. Open-back IEMs are cheaper and do not require extra hardware to use. But, if you are someone who loves doesn’t love putting things in your ear, the open back headphone can be your best option. However, when choosing open-back headphones, you need to know that they can be expensive, but they will surely deliver the best experience.
