Brainwavz M2 Strain Reliefs :(

post #1 of 16
Thread Starter 

Hello,

 

So the strain reliefs of my left headphone on my few weeks old Brainwavz M2 are starting to come off and these are from the latest batch after the pre-order that is supposed to have better glue. I tried using some PVA glue but that doesn't really stick it together that well.


Anyone have any solutions on what I can do? It's starting to peel off more and more now (especially because I use the ear gliders as well I think?) Help would be really nice biggrin.gif

Here is a way to glue the strain relief back and make it hard to come off again: Just above the rubber strain relief, notice there is a thinner aluminum section for about 2~3mm. Takes the strain relief off, make you clean off any previous glue mark and residue. Now apply some super glue on the aluminum stem that is originally covered by the strain relief as well as a bit on the thinner aluminum section, push the strain relief all the way up till it covers the whole thinner section of the aluminum stem (you might want to try it before applying the glue just to be sure). Wait 24 hrs for the super glue to reach maximum strength before use.

 

Here is a picture of what it will look like:

How do you remove the strain relief? If I rip it off it'd in two pieces.



Thanks for the great guide and picture by the way, I might try it. Is PVA glue (one you use for art and craft and etc) strong enough to be classified as "super glue"?

What do you mean by 'two pieces'?

 

PVA glue isn't strong enough, what you need is something like this.

I used UHU glue so that i dont have to worry about making a mess with a superglue. Not that strong though. Superglue is your best bet but just be careful not to leave any residue.

UHU actually also makes super glue as well. It has an easier to handle consistency and come with ultra small package called UHU Mini. That's the glue I used on mine.

no need to wait 24 hours, depending on what you use, the glue could have finished curing from a minute or so to five minutes max, yes...their is a difference between curing and drying but that doesn't apply for CA (super glue)

Even with cyanoacrylate there is a chance of breaking (happened to me once; it's somewhat brittle), so in case it won't be strong enough, you could also try epoxy. 

 

I have a different issue with my M2 strain reliefs: the left one makes an annoying noise when I'm walking or simply moving. This is caused by the cable knocking against the strain reliefs from inside. It gets really loud so I can't do sports with them. There isno such problem with the left one though. Does anyone have a solution other than removing it completely?

You probably could pull both out and shorten it. It does quite seem slightly long. But taking them out all together isn't such a good idea especially since the housing is made of metal.

This is an issue that I have as well. It's not a problem while listening when sitting, but can become quite noticable while walking or otherwise moving around a lot with them in. As in your case, this only occurs with one side of the earphones, though I can't recall off the top of my head whether it was the right or left side. These strain reliefs are the only downside to an otherwise superbly constructed earphone.

nearly half of the length of the strain relief is over a metal "stalk" so not much to shorten there...

Yeah, I think it would have been a much better idea to mold them together with the cable. I tried scotch-taping the strain relief unto the cable, but that was no great solution. Maybe I'll put glue in, but I'mafraid this will eliminate the strain relief's function entirely.

if it were molded on, they would be of no benefit

Why not? Imho if the fade-out ending would be a little thinner, they would keep their function and cause no noise (?).
