Introdução

I have been a heavy user of a Jabra Speak 510 (model PH5002W) for almost 10 years, and a couple of days ago it simply stopped working. I browsed through the internet looking for how-to-fix-it videos, but could not find a single one with the same symptoms (apparently, something as simple as a broken cable that needs to replaced).

    • I then decided to assume the risk and fix it myself. Before doing that, I purchased the smallest pack I could find of USB connectors to use in the repair, and I ended up with 5 connectors (which was good, as I would see a little down the road).

    Hi All there are specific USB connector that we need to buy or any USB connector would do for this one

    • I took a leap of faith when I CUT the cable (ugh! No way back now!). I then started to peel the cable and strip the tiny-and-extremely-delicate wires that were inside it (4 wires and a cable mesh, together with some fabric stripes).

    • With a soldering iron, I spread some soldering tin at the end of each wire (as well as over the cable mesh), and then did the same with the terminals of the USB connector.

    • I then welded each wire to the appropriate terminal (as I thought, and this is the plot twist!), according to Googled images of USB connectors, that indicated the sequence of wires as Ground/Data+/Data-/VCC (+5V). In all diagrams Google spit back on me, that sequence was represented by black/green/gray/red.

    • I closed the connector, plugged it into the USB port on my laptop, opened a track and... nothing. Instead of throwing music through the Jabra speaker, the laptop was playing the track through its own speakers, COMPLETELY ignoring my precious Jabra Speak(!!!!).

    • A few seconds later, a message appeared, stating that the USB device was not recognized by Windows and therefore was [logically] disconnected. Tried again. Nothing. Again. Nothing...

    • On my way to despair (very close to it, quite frankly), I teared the original Jabra connector (the one that was cut loose as part of my baptism of fire in this process), and found out that the color sequence was a little different...

    • ... instead of black/green/gray/red, Jabra decided to use black/grey/green/red -- which means I switched green and gray (data+ and data-), and apparently that's why the device was not recognized by Windows.

    • I pick another connector (only three left, after that!), peeled the wires again, welded them into the terminals in the new sequence (black/green/gray/red), plugged my Jabra Speak into the USB port of my laptop, open a track and... voilà! Coltrane almost brought tears to my eyes (this time for a mix of emotional and technical reasons).

    Is the correct sequence - black/green/gray/red?

    In step 8 you mentioned "... instead of black/green/gray/red, Jabra decided to use black/grey/green/red -- which means I switched green and gray (data+ and data-), and apparently that's why the device was not recognized by Windows."

    I am getting ready to repair my Jabra 510 and want to do correctly.

    Thansk!

    Hi mmitsch,

    if jabra did not issue a new release of its speaker, that should be the winning sequence. I can also take a better picture of the final color sequence and post it here (the one I took is too dark).

    • Questions, after this [more than repairing] learning process: Why on Earth Jabra uses a different color sequence (not just different colors, but simply the same colors but on a different sequence, other than the standard) for their wiring? I don't know the answer to this.

    • Why am I spending another 45 minutes writing this text? That's easy...

    • I just want to share this experience with those who love Jabra speakers but hate the way some providers (like Jabra, if I am not mistaken) try to confuse those who dare to repair their products at home, instead of taking them to a [very] expensive repair shop or even dumping such products in a garbage can. Hope you like it.

    Hi, Very thankful to you on your post, it helped me a lot to rebirth to my Jabra.
    My one, USB is not working. Now its working for charging connected with bluetooth.

    Hi Nagalla,

    Great! Good to know it was useful! In my opinion, cabling is definitely an opportunity for improvement for this great product.

    Cheers!

    I would never trust any cable colours: when you cut a cable, you have two ends, use one attached to the broken connector to measure how colours are connected to the connector and do the same with the new connector. You were lucky they at least kept the red and black as usual, with reverse power polarity, Jabra would end in smoke.

    I have the same problem, I was about to do the same. I was hesitating to open the Jabra and replace the complete cable with a more sturdy one. Inspired by your nicely dramatised repair story, I will do the same (if I find a good quality USB connector in our workshop).

    Hi Robert! Thanks for your kind feedback! Just to provide a bit of further encouragement, my Jabra still works perfectly, after this fix. Hope your case will be the same! Cheers!
