While researching for good quality headphones, you must have observed that many headphones require an amp to work at their full potential. Typically, these are premium headphones that are used by audiophiles or professionals in the music industry such as a music composer or sound designer. That doesn’t mean all good headphones require an amp

If you use a good quality headphone that doesn’t have a high impedance and good sound sensitivity, you can plug them into any portable sound source (smartphones, mp3 player, laptop) and still have a great music listening experience. To understand why that is the case, let us discuss a few details about headphone amps and why people use them. After that, we will review some of the best headphones available today that don’t require an amp.

What is a headphone amp and why is it necessary to use them?

An audio amplifier is an electronic device that boosts the electrical signal (current, power, and voltage) coming from a power source to a level that is sufficient to drive loudspeakers. A headphone amplifier commonly called an amp is just a mini audio amplifier that is more power-efficient and designed to drive headphones.

Smartphones, mp3 players, laptops, and other such portable sound sources can only supply a limited amount of power to any electronic device that is connected to it. Normally, it is sufficient enough to drive earphones and most headphones. However, some headphones are designed to consume more power than normal as they are built with better specifications. These types of headphones require a headphone amp as portable sound sources cannot meet their power requirements. 

Generally, there are 2 main headphone specifications that decide whether it requires an amp:

1. Impedance – When an electrical current is applied to any object, it experiences a resistance. The degree to which the flow of electrical current experiences a resistance when applied to an electronic device or material is known as its impedance. It is measured in ohms (Ω).

Typically, headphones that have an impedance of less than 35 ohms don’t require an amp to function. However, using a suitable headphone amp can make some of them sound a little better. Headphones that have an impedance between 35-100 ohms can still function when connected to a portable sound source. However, an amp can breathe a new life into the music quality produced by them. 

For any headphones with above 100 ohms, you need to use an amp.

2. Sound sensitivity – The Sound Pressure Level (SPL) a.k.a sensitivity of a headphone determines how loud it will be when a certain level of current is applied to it. It is measured in decibel level (dB). The typical SPL of most headphones is between 95-100 dB. Any headphone with an SPL below 90 dB requires a suitable headphone amp to function properly.

Another thing to note is that wireless headphones don’t require external headphone amps as they have built-in digital-to-analog converters (DAC) with amps inside them. Some wireless headphone models also support wired connection but they may not sound well if the firmware of the product is not properly optimized.

Here is a summary table of the 6 best headphones that don’t need an amp.

#5 Audio-Technica ATH-M50x

Audio-Technica ATH-M50x
StyleWired Over-ear closed back
Weight10 oz
Frequency Response15Hz-28kHz
Sensitivity99 dB
Impedance38 ohms

The Audio-Technica ATH-M50x is a product that is great for personal listening, as well as tracking and mixing. So, it’s popular among casual music lovers and audiophiles alike. At first glance, the impedance rating may confuse you but these work perfectly fine when connected to any smartphone or other portable sound source. But, connecting them to a headphone amp can lead to sound improvements in the low-end range. Still, they sound much better than any normal headphones with a low impedance.

This product can be described as having an impactful sound signature with powerful mids and extra weight to the bass. They are great for DJs due to being tuned for EDM. 

The build quality and comfort are not as great as V-MODA headphone models but considering the price of the product, there is nothing to complain about. Although it doesn’t support ANC, the noise isolation capability of the headphone is quite good.


  • Detachable cable system
  • Ideal for listening to EDM


  • Average build quality

#6 Beyerdynamic DT770 Pro 32-Ohm

Beyerdynamic DT770 Pro 32-Ohm
StyleWired Over-ear closed back
Weight9.52 oz
Frequency Response5Hz-35kHz
Sensitivity96 dB
Impedance32 ohms

The Beyerdynamic DT770 Pro 32-Ohm is another version of the popular Beyerdynamic DT770 Pro that is specifically designed to be used in smartphones and laptops. It sports a similar design as the 2 other models of the product with 80 ohms and 250 ohms. The differences in sound quality between the 32-ohm version and the other two versions are prominent but only apparent when using them for studio usage like mixing. The biggest difference is in the pads and cables used.

For casual listeners, they sound great since these pairs have the same tonal quality as their 2 different counterparts. The bass extends quite deep on the low-end but very precise. Plus, it never bleeds into the upper ranges. The mids are rendered with a good amount of clarity and detail but the vocals can sound a little withdrawn. The high-end is crisp and clean.

They are comfortable to wear for long music listening sessions as well. The noise isolation is top-notch due to the old-school design and leather pads.


  • Almost as good as the more pricer models of the product
  • Good noise isolation


  • The build quality is average
  • The sound signature is not neutral

The Beyerdynamic DT770 Pro 32 ohm is good for people who want a product with good noise isolation, good bass response, and specifically created for use with smartphones. The product is basically a remake of a legendary headphone that is much more costly and proven to deliver exceptional sound quality.


Headphone amps can greatly improve the sound quality of headphones that are designed to be used with an amp. However, they are not suitable for use with every type of headphone. In fact, if you pair a headphone with low impedance with a sufficiently powerful amp, it can degrade the sound quality or even damage the product. 

Another thing to note is that most premium headphones that are designed to work with an amp are created to deliver an accurate representation of the soundstage. So, they are great for professionals who mix and master music. However, casual listeners can find them irritating as they bring out every flaw in the music which can negatively affect the music listening experience. 

Not to mention, studio-grade headphones generally have a neutral and flat sound signature which some people may not like if they prefer a V-shaped, bass-heavy, warm, or bright sound signature. So, if you cannot afford a headphone amp at the moment, there is nothing to feel sad about as you are not missing out. There are a lot of other factors that determine the quality of a headphone aside from their impedance rating and SPL. 

The V-MODA Crossfade M-100 is the best choice for people who want to have a blast listening to music without connecting their headphones to an external amp. The best part is that if you ever consider pairing them up with an amp, they will only sound better. 

For people who prefer wireless headphones and don’t mind paying a little extra for comfort and features, the Bose QuietComfort 35 II Wireless is a good choice.
