We all have headphones, the is a great way to listen to the music without disturbing others. With this, we have to take care of them so if suddenly your headphones don’t sound good, you should check the speakers so how to tell if headphones speakers are blown or not?
If the headphone speakers are blown then you will feel no bass. As the drivers are out then there will be puff instead of booms. When the speakers are blown there will be no bass but you can still listen to music.
How Do Speakers Blow Out?
When a speaker blows out then it will produce a little bit of sound or no sound at all. If it is fully damaged then you will get no sound from the speaker. In case if it is partially damaged then it will produce crackling, fuzzy sound and no bass.
So the question is how do speakers blow out? This is because of two reasons
- They are operated beyond their maximum level
- When more power is applied than it can handle
When you operated the speaker close to its maximum level or at the maximum level then there are large chances of blowing out. The cone of speaker move back and forth if it is operated on its maximum level then this stretches the material and this causes the speaker’s components to tear, lose or fall apart.
The second thing that can cause a speaker to blow out is the power. If ore is applied to the speakers by the amplifier than the speaker will heat up. This can melt the glue that holds the speaker components together and when the glue melts your speaker can easily tear apart. The most important thing about the speaker is the voice coil. Voice coil is the reason you can hear a sound. If the speaker heats up then there are chances that it can damage the voice coil and if it is damaged then you will hear no sound.
How To Tell If Headphone Speakers Are Blown?
Headphones speakers can easily blow. So the question is how do you tell if it is blown. If you bought a new pair of headphones then before testing its speakers you should listen to music test it at low and high music. This is the best way to tell how loud can your headphone speaker get.
In a case when you turn up the music too much and you can’t hear the music correctly because there is too much distortion. Turn up the bass of the headphones. If they sound good and you can feel the bass then your headphones are in good condition. If not and there is no bass then there is really a large chance that your headphone speakers are blown.
Another thing I want to mention is that if you can’t hear the sound nor the bass from headphones then there are chances that the built-in amplifier in headphones is not powerful enough. It is better to change the headphones.
The Headphone Wire
Sometimes there will be no sound or the bass on one side of the headphone. Right channel will work but left will not or vice versa. This can be because of blown speakers but this can be because of a number of factors. One is the amplifier and the second one is the wire.
Yes, wire. We forget that headphones work with wire if they are not Bluetooth. Wires can be really messy. Headphones wires are not durable they can break easily and also for both speakers of headphones wires are completely independent.

There is a very small number of cases when the speakers get blown. This can be due to low quality or due to physical push on the driver. So if the speakers are not giving you the best output what should you do. How to test speakers for damage?
If your speakers are not giving any kind of sound the best to test if they are damaged or not is through the multimeter. With steps, I will show you how to test your speakers
Find out what is the impedance of your speaker. Usually, speaker impedance is 4,6 and 8.
Turn on the multimeter and move its knob to resistance mode.
Connect the two wires of the multimeter to the speaker. If the multimeter shows some value other than zero then your speakers are ok. If not then your speakers are damaged.
Let’s say you have 8-ohm speaker then through multimeter test you get 6.9 ohms. This is less than 8 but ok.
