Broken Headband on Bluetooth Headphones | Repair Instead of Replace

I purchased a medium of the road Bluedio headset that I have been using in both Bluetooth and wired modes. It’s pretty decent and they fit my head well. Unfortunately, my Magilla Guerrilla handling of it I snapped the headband. I didn’t think I was being rough with it but I do have a track record of such things. The break was on the left side near the slide out adjustment and although the set was still wearable, it felt like one ear cushion loose enough that it would slap the side of my head at every turn.

I had three choices, buy new headphones, deal with it and get used to the gentle paddling of my left ear or lastly, fix it and see if I can return it to an acceptable, usable condition. The paddling was completely unacceptable to live with and the the headphones would no longer fit snugly to my head so this option was ruled out. The option to buy something new was also out. My budget had already been allocated and I am not interested in getting new hardware when these were still electronically functional. Why wouldn’t I at least attempt a repair?

The padded headband was well stitched together in such a way that the stitching was easy to delicately remove. This exposed the poly-carbonate (I am assuming) structuring beneath.

Looking at it, the fix wouldn’t be difficult at all to do it, with the right combination of adhesive chemicals: Loctite 444 Ethyl cyanoacrylate liquid adhesive along with Loctite SF 7452 cure-speed accelerator for the aforementioned adhesive.

The nice thing about the accelerator (a trick I learned at work), you can add adhesive and immediately follow it with the accelerator to layer on material and consequently, greatly increase the strength. This was a technique demonstrated when I fixed my broken Porter-Cable Drill some time ago.

Just a few minutes of gluing and applying the celebrator, had extended the life of this headphone set. Would a normal upgrade to something new and better? Probably but that is just not how I roll. I can’t bring myself to toss out something that is easily repaired. I have yet to sew the padded headband back together but I am no longer getting paddled by the ear pad and when I do handstands, they don’t fall off of my head.

This is not an advertisement for Henkel but fixing toys or equipment is easily accessible to just about anyone as long as you have these two chemicals. It opens up a whole new world of fixing possibilities. I have seen YouTube content creators struggle with gluing broken bits together, clamping them for hours at a time when the job can be done in a fraction of the time. Sure, these are not the cheapest of products but they are extremely effective and drastically reduces the likelihood of your project ending in frustration.

  1. Hola! muy bueno el dato de utilizar Loctite como pegamento para la diadema del auricular. Me dedico a reparar cosas de audio y me trajeron el mismo modelo de auricular, pero roto en ambos lados y no encontraba la manera de repararlo. intente con otros pegamentos, pero el movimiento al abrir la diadema hace que vuelvan a romperse. tendre que buscar algún reemplazante al loctite ya que en mi pais (argentina) no se consigue a un precio razonable.
    saludos!!!!

    1. The trick is to layer it on and harden it a few times. I actually had to fix it a second time because I didn’t put on enough glue the first time. I wish you a successful fix!
