Tienes unos auriculares que no te funcionan, no te preocupes, en este video tutorial te muestro como puedes localizar la avería y repararlos.
Comenzamos con la medirición de resistencia de los auriculares en el conector jack haciendo uso de un polímetro. La resistencia suele dar entre 30 y 40 ohmios, el que de algo mas o algo menos no es indicativo de avería, sí lo sería el que el mida 0 ohmios o infinito, como ha pasado en los audífonos del vídeo.

Una vez localizada la avería en una unión de cables, procedemos a su reparación.
El procedimiento que se propone se compone de cinco pasos:
1.- Localización de la avería con la medición de un polímetro
2.- Pelado y preparación de cables para su correcto soldado
3.- Soldadura de los cables
4.- Aislamiento mediante tubo termoretráctil y silicona caliente, haciendo uso de una pistola de silicona caliente
5.- Pegado de una almohadilla y montaje final

Hello, friends! I’m Leandro Garcia
I'm going to show you how you can repair

0:00:05.080,0:00:09.649
your headphones. We are going to see within each of them

0:00:09.649,0:00:13.549
we are going to check its resistance with a multimeter

0:00:13.549,0:00:17.650
we are going to solder the wires

0:00:17.650,0:00:21.199
and finally we are going to isolate it

0:00:21.199,0:00:23.779
we are going to do it in five steps

0:00:23.779,0:00:27.329
we are going to use these tools.

0:00:27.329,0:00:32.620
Let's do it

0:00:32.620,0:00:37.550
We start checking the resistance of the
speakers, it must be about

0:00:37.550,0:00:40.220
30 or 40 ohms

0:00:40.220,0:00:44.460
we see that one of them does not have
continuity

0:00:44.460,0:00:48.270
we may think that the breakdown is
inside because the wire

0:00:48.270,0:00:49.340
might have been unsoldered

0:00:49.340,0:00:53.640
We open the headphone

0:00:54.940,0:00:56.520
and we check that the wires are ok

0:00:56.530,0:01:00.899
therefore, we
assume that the breakdown is not

0:01:00.899,0:01:04.460
inside the headphone.

0:01:04.460,0:01:07.380
we see that we have a bad connection


0:01:07.380,0:01:11.340
It will be here where the breakdown is

0:01:11.340,0:01:16.680
Second step. We are going to get the wire right,

0:01:16.680,0:01:23.000
In order to do that, we cut

0:01:23.000,0:01:29.320
and peel the connector’s end,
We notice that there are three wires

0:01:29.320,0:01:32.100
We peel the wire on the headphone edge

0:01:32.100,0:01:38.640
we can see that there are two wires

0:01:38.640,0:01:42.640
The other headphone’s wire

0:01:46.400,0:01:58.680
as the cable is enameled, we must
remove it with a cutter

0:02:03.160,0:02:04.400
with a lighter

0:02:04.400,0:02:06.560
we burn it to remove

0:02:06.560,0:02:08.099
the residue

0:02:08.099,0:02:10.549
that remains

0:02:10.549,0:02:15.319
we have just ready the wires coming from the
headphones,

0:02:15.319,0:02:19.499
We get them together in the earths

0:02:19.499,0:02:24.269
and we must weld it with the wire from the
connector, taking into account the

0:02:24.269,0:02:29.369
green and red colours and the earth.

0:02:29.369,0:02:31.099
let´s go to step three

0:02:31.099,0:02:34.649
Welding the wires. We prepare the
wires

0:02:34.649,0:02:36.519
tinning the ends

0:02:36.519,0:02:42.829
We try not to leave any
drop in the wire

0:02:42.829,0:02:47.699
We do the same with the other end of
the wire from the connector

0:02:47.699,0:02:54.839
but this time we are going to let a drop of tin


0:02:54.839,0:02:59.749
we are going to use heat shrink tubing to
get a perfect isolation

0:02:59.749,0:03:07.109
for both individual wires, as
for the group

0:03:07.109,0:03:08.419
we put the

0:03:08.419,0:03:12.619
thick heat shrink tubing first

0:03:12.619,0:03:16.499
and then each individual tube

0:03:16.499,0:03:18.399
let´s weld

0:03:18.399,0:03:22.879
we see that we have to match
each colour

0:03:22.879,0:03:26.829
and the earth with the earth

0:03:26.829,0:03:29.519
we must apply very little heat

0:03:29.519,0:03:34.019
so that the resin containing
in the tin does not disappear

0:03:34.019,0:03:39.329
and we heat it with a lighter

0:03:39.329,0:03:43.309
before continuing with the process we are going
to ensure that we have the

0:03:43.309,0:03:48.229
required resistance of about 30 or 40 ohms

0:03:48.229,0:03:51.739
indeed we have it in both
headphones

0:03:51.739,0:03:52.979
Therefore

0:03:52.979,0:03:55.659
in the fourth step, we are going to isolate

0:03:55.659,0:04:04.729
the connection completely. We use a silicone gun to do it.

0:04:04.729,0:04:11.059
both on one side as on the other side

0:04:11.059,0:04:15.579
We place the heat shrink tubing

0:04:15.579,0:04:18.289
we apply heat
