  1. Got delivered today through Amazon , tried pairing twice by turning the detector on and then headphones , and off and on a 2nd time . Then the 3rd time turned on the detector , then the headphones - paired with the + works good . Now to go out & play . And the price was ok also , https://www.amazon.com/gp/product/B01A0EAYDI/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Thanks Chase
  2. " I'm kind of surprised by this statement because you know your way around a soldering iron and circuit board like nobody's business. Wish I had that skill. I'm all thumbs and love to burn up electronic components if I try to dive in myself, but the throway nature of surface mount micro-electronics makes DIY repair hard these days. " Chase Goldman What I am referring to age wise , is programing / computer controlled , vs. circuit board work - thats just mechanical working with my hand/eye coordination . Or put another way - I could be a brain surgeon , I can work on brains / but cannot work with brains 😉 Or , my hands & eyes are coordinated , but the brain - hand coordination is problematic Thanks for the links .
  3. I do realize that there is issues , faults all over the place . Generally , maybe partially because of age I get frustrated with over complication , it seems to me most that are younger grew up with all the extra bs and are just use to it / don't know the difference . I've been in one business or another for over 50 yrs. and see an endless gouging [ started at the top and everyone below has to gouge to keep going ] that is just getting older faster than I am ;( Probably pissed some , my way of thinking is you can only piss yourself off , either that what you want or ?
  4. Sure would like to find some of those , every one I've check has been sold out , or other issues and costing excessive . Also most of the comments leave lots of doubt , lack of enough to confirmation , that makes it a toss up ?
  5. This is not Minelabs issue - kinda ? Well they picked the headphones . Might have to find another supplier / manufacture of metal detectors , someone who will not leave customers in a deep dark hole ? Especially when they jackup the price by 2-3 times ? Anybody else a little or more unhappy .
  6. I looked those up , only replies were from Amazon , and none available . I did not have the option of getting into them for a couple weeks , so not real hopeful .
  7. I do my own repairs , but typically I'm last in line ;( Got deeper into the headphones today , and realized I was out of flux for doing ic chips . Got the main IC off the board after taking a closer look & seeing corrosion on the edges . Took some bad pictures , will take some more after I resupply and clean up more . After removing the IC with hot-air station , and turning the chip over you can see [ bad picture ] corrosion - yellow on a couple edges .
  8. Well the battery & charging system works ok , but does not turn on yet . Now have to get to costumers repairs , mine are last in line . Will update on progress .
  9. I can access most of the electrical parts , including the battery , the plastic / case is what I would not have access to . I suspect the battery is ok , it probably just shut down when min. voltage was reached . But I am waiting for the Deoxit carrier drys off , then test . I will report what comes of it .
  10. I do not commonly do photos / videos , and was eager to remove salt and did not take before cleaning pic.s . Very heavy salt / corrosion inside of micro-USB plug and on the circuit board where the electrical / surface mount connections are made . Also same on larger board at some of the wire sold points . So soaking with alcohol & scrubbing with nylon brush , Q-tips & a carved down toothpick - to get inside of the micro-USB socket , at least half dozen times , then used Deoxit Gold with same scrubbing about 3 times , looks like new with magnification . Will test in a day or 2 , need to leave Deoxit on all surfaces & wait to let dry - before plugging in . The lithium battery has a BMS - Battery Management System board on one edge of battery , which if working as it should , would have shut down battery after low battery voltage is reached , so latter plug in to charge back up & test . The short created by the salt turned the unit on / kinda , & drained the battery . Hope this helps others when they fall into water , in this case salt water moving from boat to dock , heading to the beach . #1 , 2 , 3 , 4 with boards removed & cleaned . #5 , 6 with boards installed . #7 speaker back in , four holes for screws holding speaker in place . #8 showing foam pad in place , look for little tabs on the inside edge - these clip the ear-pads in place . #9 mostly back together , took all screws that I could see in the headband trying to get apart - as it turns out - did not have to remove any screws that you can see in both the ear pieces or the headband .
  11. Ok got them apart , they unscrew . 1st have to pull the ear pads off by squeezing the pad with a couple fingers and also try to get under the plastic edge with another finger nail . Under that is a flat foam pad just lying there , under the foam pad are four phillips screws , now apart enough to start repair . Most of the damage was in the micro-USB , and the switches , so soaking a bunch with alcohol , Q-tips & rubbing with wooden toothpick . I will wait and clean again tomorrow , then treat with one of the top contact cleaners Deoxit Gold . I'l try to get some pictures & post .
  12. Again my main interest is taking apart - I have repaired lots of electronics , but this may snap together / apart ? Or may be glued , so crack apart , would like to know in advance to either snap or crack 😉 ? Now home and want to expose the boards & connections , figuring that the only long term fix is to scrub with alcohol .
  13. I'm still left with a couple questions . Anyone open the headphones ? And I would feel guilty , but is dropping in water / accidents under warrantee , about 5 months old ? Found the same old junk on FL beaches , money & jewelry , no treasure yet 😉
