How to increase clamping force on headphones? Quick Ways

I currently have an excellent pair of headphones. They sound great, and I love them; the one thing that frustrates me sometimes is the HD650 clamping force which becomes loose. They seem to fall on my ears, and even pushing the cups makes them sound noticeably better. Everybody faces this issue, aren’t you? So, How to increase clamping force on headphones?

There isn’t much you can do to increase clamp force since the material in the headband and its shape is such that it can undergo more plastic deformation outward and more elastic deformation inward.

If you’re desperate, I’d suggest carefully stressing the two sides together. Hence, they’re under noticeable tension but parallel to each other, holding them there for a day or two with a band or something similar. In this article, I will tell you what clamping force is, the causes of clamping force in headphones, and how to increase the clamping force on headphones:

What is the clamping force of the Headphones?

Its force is magic to remove the plugin from the charging port. It is important to note that we have to use mild pressure when using the Magic Clamp. The Headphones will stay in place until we are ready to remove them. If we use too much pressure to remove the Headphones, they may break. 

How to make over-ear headphones tighter?

Headphones are designed to fit the most comprehensive percentage of the general population. However, every person is different, and some wearers may feel the headphones’ headband is initially too loose. Like when I used Sennheiser momentum 3 clamping force became pretty less, and I had to increase that manually. 

The only thing I’ve thought that could work would be to try and bend them a bit by putting them in between two boxes, slightly bent inwards, and leave them like that for a while, but I’m afraid that the headband might break doing that.

A common trick to make the headphones’ headband tighter is to place the headphones over something (like a stack of books) slightly smaller than the headphones currently are and then wrap the headphones with a cord or elastic band to squeeze them inwards to make them tighter.

The object between the headphones is to ensure that the headphones are not squeezed too tightly as you don’t want the headband to crack. The headphones may need to be left in this position for a day or two, or the process may need to be repeated a few times until the desired headband tightness is reached.

What causes clamping force in headphones?

The clamping force is due to the permanent deformation of the headphone drivers after they have been physically stressed a few times. That’s why it is so hard to take earphones on and off. 

The drivers would deform and make the earphones stiffer. Many factors affect the headphones clamping force, such as the shape of the driver, headband material, the way the headphone is worn, the shape of the ear, and the form the ear rests in the ear pad. For the most part, the smaller the size of the headphone driver, the higher the clamping force. 

How to increase clamping force on headphones?

The easiest way to increase clamping force is to apply some clamping force while they are on your head. It will increase the diameter at the point of contact between your head and the headphones, increasing the clamping force. The other way is to stretch them a bit before use. Again, it will increase the diameter at the point of contact between the headphones and the head.

Ear cup material and driver diameter determine the clamping force of a headphone. Also, the curvature of the ear cups affects the headband size, the ear cups’ design, and the clamping force. Moreover, the smoothness of the headphones’ surface also plays a role.

Clamping force is an important consideration when it comes to headphones. Too much clamping force can cause the headphones to become unusable, while too little can lead to damage and audio leakage. 

There are a few ways to increase clamping force on headphones, but finding the right one will require some experimentation.

  1. Use a pair of headphones that are balanced, not unbalanced. Balanced headphones can have clamping forces as low as 50g and offer a broader range of sound quality.
  2. Use a pair of headphones that are low-frequency-sensitive, not high-frequency-sensitive. A pair of headphones with a low-frequency response will provide better bass output than those with an overly high-frequency response. 

Weight Factor and Clamping Force

Many methods can increase the clamping force on headphones, but one of the best ways is to use a weight. It will help to increase the clamping force on the headphones and make it easier to hold onto them. 

The weighted headphones are an excellent way to increase the clamping force on headphones because you can use the weight to make it easier to hold onto them and not worry about losing your grip.


I hope you learn a lot in this article about increasing the clamping force of headphones. The clamping force of most headphones is such that it hurts the ears after a few minutes of wearing them. Excessive clamping force is uncomfortable and can also lead to unwanted health problems.
