Blue Tooth Headphones Fell In Water , Repair Take Apart ?


Recommended Posts

Dropped the headphones in salt water ;(

Has anyone taken these apart ?

Want to try to clean , also I assume [ always dangerous ] that this is not covered under warrantee ?

Remember that when you dry them put them in a bag and fill with rice. The rice will draw out more water over a couple of days than the air will. Let them dry for several days and they should be good.

For more reasons than I want to get into , but for long life ?

I do circuit board repair , and do not accept rinsing with distilled water or especially the rice thing as a fix / repair , but can be parts to a complete repair .

Not that either do not have some beneficial aspects , but are very limited / incomplete in trying to solve any water issues 

Fresh water has many kinds of components in it - depending on the source , and most all leave corrosive effects  .

In electronic manufacturing - they use deionized water for cleaning , mostly to replace some other chemicals .

In repair isopropanol alcohol is most common .

Then in this case - salt-water is where I might start using as clean of water available !  - but on a boat away from any of the above , so being able to open the case and rinse off and scrub with drinking water is the best that can be done at this time ?

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 😉

Call ML for the absolute answer to that question (but I think you already know the answer).  The warranty is against design and production defects if used in accordance with the specs.  The BT headphones are not designed to be exposed to or submerged in water according to page 61 of the user manual:

”Do not expose the headphones to liquid, moisture or humidity, as the headphones are not waterproof.”

You can attempt to plead your case with the repair center, but the words are pretty clear.  You took a risk, gambled and lost.  There are a number of water resistant  BT APTX LL earbuds out there that cost much less than the ML phones (~$30).  Clone (non ML branded) or similar equivalent BT headphones cost between $40 and $60.  Quest makes a rain resistant over the ear low latency BT set at about $90.  Frankly, if you are regularly entering the water to detect, you should probably get the appropriately certified waterproof phones because even the water resistant phones mentioned above likely can’t survive an accidental dunking. 

Attempt to repair them yourself or just take your medicine and buy a new or used replacement pair, if the repair center does not take mercy on your situation.  

Internal salt water damage to electronics is pretty obvious to a repair technician, so being coy about the actual failure situation will likely not get you anywhere.

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 .

They should snap  together like several other brands that I have repaired before. To keep from scratching them I had to use a small blade dull knife to open. I heat them up a little to make the pieces more flexible.

I HAVE NEVER OPENED THIS BRAND BEFORE, so be careful.

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 .

      Has anyone tried them with a metal detector?
      I came across an article which displayed some Bose audio sunglasses.  The concept was not something I had really considered but when you read about them they are built for athletes that need to be aware of their surroundings to avoid accidents.  We detect in areas where we need to avoid accidents and critters also so hearing outside of headphones is beneficial.  This would also have the potential of eliminating hot and or uncomfortable headphones for me in the desert.  I don't think they could work well at the beach with crashing waves.
      Maybe we can begin a review of these Bose and other audio sunglasses here.  Of course there would need to be some with LL and other technical specifications to work with our equipment but it could also be a new product idea for one of these companies.

      Last week,  I attempted to power on the ML 80 headphones I use with the Equinox 800.  I purchased these new in March 2019.  They would not power on.  I charged them:  the 3 red LEDs flash for about 10 minutes and then turn off, as if headphones were charged.  But, the headphones still will not power on.
      I attempted to contact my dealer and ML, but neither have yet responded.  Does anybody have any novel ideas to try, or troubleshooting, remedies?  I would greatly appreciate the help!
       
      Thanks,

      Over the years we've touched on the difference between High Impedance vs. Low Impedance headphones.  Historically, the headphones designed for detecting have been High Impedance, and all were equipped with 1/4 inch headphone plug.   Everyone developed a preference for their brand because of the way they fit and sound.  These days more detectors are set up for the 1/8 inch headphone plugs and a few detecting headphones have offered that choice.  The technology is clearly moving away from all wired headphones in favor of wireless.  The market is really directed at music and communication devices, not detecting.  I'm just curious how the impedance issue affects the newer technology.  The latency of wireless is a completely separate discussion, but may be necessary to understand the importance of Impedance.  
      I have always used in ear monitors rather than over the ear headphones.  It's just more practical in the desert environment of sunny Yuma.  The majority of "ear buds" for lack of a better term are low impedance designed for listening to music on low powered handheld players.  The high impedance ear monitors are available but quite expensive.  The GPZ tends to overpower el cheapo ear buds and produces a really unpleasant sound. 
      My question is twofold: what was our understanding of the importance of Impedance in the old days with wired headphones and how/if that has changed with wireless.

      We detectorists are accustomed to dealing with nature (wind noise) and human nature (traffic noise) while detecting.  In a significant section of the USA, some of us get an added bonus (err, annoyance?) a few times in our lives.  I assume most of you aren't aware of this 17 year occurrence of cicadas known as Brood X.  Here from Wikipedia are the states most impacted:
      The brood's next major emergence will take place during 2021 in these 15 states: Delaware, Georgia, Illinois, Indiana, Kentucky, Maryland, Michigan, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and Washington, D.C.[5][3][6]
      I don't remember 1970's emergence and in 1987 I was in California and Saskatchewan the entire time they were performing.  But I experienced the 2004 emergence.  It's pretty impressive.  Cicadas are present at least in the Eastern USA every year.  They typically compete with crickets in terms of volume and audio frequency (to my untrained ears, anyway).  However, the Brood X is like sitting in the front rows of a rock concert compared to the comfort or your living room listening to music.  Unlike crickets, they don't reserve their singing to merely the evening hours, either.  Here's an excerpt from NYTimes regarding their audio volume:
      Sounds up to 90 decibels could be measured standing directly under a tree filled with cicadas. A motorcycle, by comparison, can put out sounds up to 95 decibels, which can damage hearing after about 50 minutes of continuous exposure, according to the federal Centers for Disease Control and Prevention.
      You don't need to be under a tree to experience the impact, either.
      BTW, the 17 year emergence cycle is an example of nature understanding mathematics.  17 is a prime number (divisible by only 1 and itself if restricting to whole numbers).  The reason, though, with two competing hypotheses, is still being investigated.

      I was one of the first to get an 800 in the United States.  I got on Bill's waiting list several months before the release.  Since then I've had to replace the control unit because of a broken switch.  Everything has worked well and I've found lots of good targets.  Along the way I bought a pair of Avantree headphones and they work fine but I prefer the Minelabs.
      Today I put them on the USB charger.  I've had to fiddle with several different power cords the last few months but eventually I get the red charging lights to come on and that was the same today.  When I picked them and the charged 800 up the charging lights were out per normal.  When I got to the beach to connect I couldn't get the 'on' tones for the headphones.  They were completely dead.  I've since fiddled with them and tried multiple cables that had charged them before but I can't get the 3 little red charging lights to come on.  I've cleaned the mini leads with alcohol and jiggled everything but no go.
      Is it dead?  haha
      I'll use the Avantree until I can get another pair of the originals.  They don't need to be new.
