Why the bass doesn´t sound?

The bass in the skullcandy cruhers does not sound, i don´t know the reason, i think it might be the aux cord

Those are the photos of the main circuit. I see it fine

Is this a good question?

Hi,

Just to clarify. Do you hear sound in both left and right headphones or only one? If only one, which one L or R? Or are you saying that treble sounds are OK in both L+R but not bass? If it is the bass, that is determined by the circuitry in the headphones. The cord only determines whether the sound is to be played in the left or right headphone.

The treble is fine in both right and left, but the bass is not working at any side, I checked the circuitry in the left side, where the main circuit is, and i think everything is fine, it looks solid

Hi,

Have you checked that the AA battery in the headphones is OK? Try a new one. It powers the amp for the 'bass'

If the battery is OK or a new one makes no difference, can you post some close up pictures of the main circuit? Adding images to an existing question

Since it appears that both speakers are working as such, the circuitry that 'enhances' the bass is obviously the problem. Unfortunately with electronics even though it looks OK doesn't mean that it is.

I've replaced the battery with a new one, and the bass still doesn't sound

Hi,

Looking at the lower picture, there are connections for (from R to L) speaker L +ve, L-ve, R +ve, R -ve then I think it is Batt -ve and Batt +ve.

I suspect that the two wires (red and red/green) on the Batt +ve and Batt -ve go to the other headphone cup where I think that the AA battery may be located. The specs say that it needs a AA battery to drive the bass.

You may have to open the other speaker cup and replace the battery.

Hi,

As you have replaced the battery and verified that it is in the correct way, check the following:

With a DMM (Digital MultiMeter - Voltmeter function) check that you have 1.5V DC across the Batt +ve and Batt -ve connections on the circuit board. If not ensure that the battery holder terminals in the other speaker cup have enough tension on the battery for a good connection and that they are bright and shiny. Here is a link that shows how to increase the terminal tension.

If there is still no battery reading across the battery connections on the circuit board then you have to remove the battery and using the DMM (Digital MultiMeter - Ohmmeter function) check for continuity of each of the wires from the battery holder terminals to the circuit board. If one of the wires is open then you will have to remove the battery holder and inspect the connections underneath.

If all the above checks prove OK and you can read 1.5V DC at the circuit board then there is a problem on the board. Unfortunately, without a circuit diagram it will be difficult to ascertain which component is faulty .
