A headphone with 50 to 75 ohms or slightly more is considered low impedance. Here we review the six best low impedance headphones, including Philips SHP 9500, Beyerdynamic DT 770 PROand Audio Technica M50X, that deliver amazing sound quality audio.
Impedance is among the basic specification included in each quality pair of headphones and in each audio source. It’s the process of transmission and resistance that headphones & earphones have to electric current transmitted by amplifiers. It’s measured in ohms that often range between 8 and 600 ohms depending on headphones models.
Generally, most people who want to buy new headphones don’t focus on the output impedance. But, it’s at this point they make a huge mistake without even realizing it. Yes, impedance may seem insignificant at first; however, it influences your overall audio experience. Simply put, the impact that impedance has on headphones is tremendous.
Low impedance headphones are a suitable choice for newcomers into audio leisure. As a starter, you don’t need headphone amplifiers or DAC/Amp to use these models as you can operate them directly with your smartphone, DAP, computer, or Mac. What makes low impedance headphones excellent is the fact of being independent of any source. However, they are not the better choice if you want to upgrade your gears and need to buy some units like DAC/Amps in the future.
So, if you are want the best low impedance headphones for one reason or the other, keep reading our article. We will be looking at the six top-rated models in the market.

Factors To Consider When Choosing The Best Low Impedance Headphones
Typically, the headphones convert the electric signal into an audio one, and the effectiveness of this process determines the sensitivity of the headphones. When using a certain power source, you will know how loud the headphones are by checking their sensitivity. It’s normally measured in Decibels of sound pressure level per milliwatt (dB SPL/Mw).
Higher sensitivity ensures better device performance with minimal use of a power source. At the same time, lower sensitivity ones need more power to provide better audio quality.
People normally have a different preference regarding specific frequencies, which is among the most decisive ones. It shows how an audio component is tuned across the frequency spectrum; bass, midrange, or treble.
When people grow old, they become less sensitive to higher register since this frequency weakens first in hearing loss. That is why older and middle-aged listeners prefer bright headphones because their emphasis is on the frequency to help them hear properly.
Since impedance isn’t a static value, it might change over frequency. In the technical specification, impedance rating is measured at 1 kHz. The impedance is usually higher at lower frequencies, sometimes extremely higher, thus affecting the frequency response. The model also influences frequency response amplifies to some extent.
When the amplifier’s output impedance is high, it will turn the model impedance curve into frequency response changes that you can hear. However, the effect is more significant for headphones with low impedance.
Models with lower impedance have a high load on their output stage, which means the output circuit needs to work extra hard to generate more distortion. Therefore, the greatest low impedance models perform better regarding volume, although they are not perfect in distortion.
This is the amount of control an amplifier has over the driver, often described as the amplifier’s ability to control driver motion when the signal stops. Damping factor is very common in low-frequency reproduction. The low damping can cause loose, boomy, and indistinct bass, whereas high damping makes bass sound cleaner and tighter, though subjectively less warm.
You measure the damping factor ratio between the amplifier’s impedance and the driver’s impedance, expressed in 2:1 format. The first number is your model impedance, and the second one is the source output impedance.
Price will always be a constant factor to consider as well when purchasing various products. However, it’s always affected by materials, brand, type, style, etc. Your financial ability also influences your decision. Several models are out there with different prices, so it’s up to you to pick the suitable one worth the value. Each one of them has special features that make it outstanding as well as its pricing.
Frequently Asked Questions
Why Should I Go With Low Impedance Headphones?
Nowadays, most headphones come with exceptionally low impedance levels to work perfectly on your home receivers or your smartphone. Yes, the high impedance models can be the right choice for home-based usage but remember it doesn’t work well with your smartphones.
What Impact Will Impedance Have On Sound Quality?
Funny enough, the lower impedance headphones will not sound good when you connect them to high-quality audio receivers or any studio-grade sound equipment. Since the audio output sources have a lot of electrical juice running across them and some of that electricity will be transferred over, i.e., pumping anywhere north between 100 to 600 ohms or more, which could blow the doors of low impedance units.
It’s the same way high impedance models headphones would sound terrible connected to a smartphone with lower power output. So, common impedance models sound as bad when connected to higher output ones. Always keep in mind there will be a huge impact on sound quality depending on the kind of impedance you’re dealing with.
It’s also common for impedance mismatches to cause audio soundstages to be enhanced on some sources and not others. If you want the bass response to be all over, the mids will be washed out and completely impossible to hear.
Is There A Sweet Spot Of Ohms A Headphones Model Should Hit?
Yes, most of the time but not always. If you listen to music casually regularly on your smartphone, computer, or tablet, the suitable headphones should rate between 8 and 32 ohms. The low impedance models will work wonders on the underpowered audio device. As a result, you hear the music clearly in a way that’s difficult to do with higher impedance units.
But, if you will listen to music through high-rated equipment, you need a higher impedance headphone that will stand such kind of power without flinching. If you have a great sound system or a producer, these models will be suitable. You will realize how things are supposed to sound once you get your audio source and headphones in perfect harmony.
Headphones with low impedance are great since they are not usually dependent on the source. However, inappropriate impedance won’t cause you any major problems. But, it’s advisable to check its compatibility with the audio system in your house. Remember, a too low or high impedance of your headphones might spoil the audio experience.
In our list, SENNHEISER HD 660 S- HiRes Audiophile Open Back headphones emerged the best with an impedance of 150 ohms. Its transducers are hand-selected for precise 1dB left to right matching tolerance for exceptional accuracy and presentation of stereo spatial features.
