If I'm understanding this thread correctly, the problem that needs to be addressed is the "natural" reproduction of the audio signal input into the headphones.  It seems most headphones produced for the listening consumer market color the sound by favoring bass frequencies.  What detectorists are looking for is essentially the same thing an audio engineer/producer is looking for - accurate reproduction of the input signal. An audio engineer would never mix down an album using "boom box" speakers. They would insist on a quality studio monitor with a frequency response that didn't favor any particular frequency and reproduced all frequencies as given. 

If I was unhappy with the audio quality I was finding in consumer headphones, I would start looking at headphones specifically made for mixing accurately reproduced audio, as opposed to headphones made for casual listening.

They will cost more... 😉

I have found suitable phones and bought 6 of them. Maz Super Red's are the best since the old Gray Ghost NDT . perfect for Minelab machines.

What would be nice is if the companies use standard bluetooth so any bluetooth headphone and pinpointer for that matter would work with bluetooth compatible detectors.

Agree  but it would have to be low latency bluetooth such as APTX LL which lowers the perceived audio delay down to less than 40 ms or so. 

Most "regular" Bluetooth protocols such as SBC, AAC, and even non LL APTX have latencies from 60 to 250 ms which is readily noticeable (and intolerable) on a normal coil sweep swing. 

This severely limits the selection of compatible 3rd-party bluetooth headphones available for purchase.  It is apparent that there is not a huge demand for low latency wireless headphones so APTX LL does not appear to be a widely adopted BT protocol in the consumer market.  That fact and manufacturer profit driven motivations tend to drive detector companies to hawk their own custom proprietary low latency wireless solutions limiting the selection of cross compatible wireles audio systems to the relatively expensive Quest, Garrett Z Lynk, ML Pro Sonic, and Nokta wireless systems that lock you into specific wireless receivers or headphones.

I'm a newbie and have a Minelab 600 withy wired headphones. After being almost strangled by the wire(huge windstorm) I am looking to upgrade to BLUETOOTH headphones. I am an ex commercial fisherman and all this info is mind boggling. Trying to decide what headphones would be the best( surf/sand detecting). The if on the m80 Minelab isn't good.

Any help would be a blessing. Thanks in advance.  I live in Central Florida. Joe B...aka...Ancient Mariner

Any bluetooth headphones that use the low latency APTX-LL codec should work.  Low latency ensures that you hear the target response consistent with the position of the coil over the target.  Most non-low-latency Bluetooth phones introduce a signiificant delay such that by the time you hear the target signal your coil has moved inches beyond the actual target position during your swing.

Here are a couple phone models on Amazon that are known to work with Equinox and that are considerably cheaper than the ML branded accessory phones.

Thanks for the information as you and many others on here always give us newbies great information and good products.

I am still hoping to get out before the freeze here in the Mid-West.

I somewhat agree.  When I must use headphones I currently use Sennhauser 280 pro (I think that's the one) for my Etrac and they'll also fit the Goldmonster with the adaptor that comes standard with the phones.  They'll fit both 1/4 and 1/8" plug.  I also use the long corded, noise canceling, audiophile phones for my drum practice. Phones are about $100 if I remember right, and have been using the one pair for at least 11 yrs now.  Never had a pair of Minelab equipted Koss phones I liked?

 If you want the best that fit your hearing needs you have to make them yourself.  These are wired, waterproof headphones for the Minelab Excalibur. Everyone knows how bad the ML waterproof headphones are....So after several years of experimenting and testing I was able to find a combo that allowed me to hear deep targets no one else could. I ended up using Unlimited audio 50mm piezo's that gave me the higher pitch, 2400HZ that fit my hearing then add a unique horn design to amplify the audio for all metal hunting only. Being they work great for me on the excalibur I tried them on the Fisher "AQ" Limited and no doubt they are pushing the limits of unheard deep targets of the "AQ". 

I did test several speakers / earphone elements and these were the more popular used in Aftermarket metal detecting Head phones.

Audiosears higher tone..used in several of the bigger name HP's..Sunrays Pro, Black Widows, then a few of the GG models and if I remember correct there is one set that is made in the UK that uses them also.

Then the bass sound of the old Rat Phones...using Kobitones...Many swore by the Rat Phones years ago but now no longer available. 

I was able to make all of the speakers I tested water proof using a proven method.

About this time last year I decided to purchase a quality set of headphones to use as a backup pair for my wireless detectors, In talking to several vendors it seems the Gray Ghost line changed the type of speakers they had been using, I recall that the ownership had also changed about the same time. I ended up speaking with the owner & maker of Killer B's. He stated that he specifically used audio communication type speakers that had little bass. This was to give the tones a clean & crisp report. I understand Sun Ray uses like speakers. I purchased a pair of the Killer B's and have been very pleased with the sound. The overall comfort & quality are also very good. I use them now as my primary headphones on the Vista X, running thru a Garrett Z Link set up. The Garrett MS 3's also sound very good. I plan to purchase a set of their MS 2"s to serve as replacement back ups. Not sure how either would sound on a Minelab machine but to me they are great sounding on the Vista X, Anfibio & AT Max.

Hi... my primary arrangement of earphones are DetectorPro Black Widow Headphones which are my undisputed top choices, and the earphones I would get first among all others... or on the other hand the earphones I would get on the off chance that I could just have one sets.

I was simply going to get a second pair of the Black Widow Headphones yet chose to get my next top choice... DetectorPro Gray Ghost NDT Headphones, which are the top choices of my companions Rob, Ken and James and are utilized by the majority of the relic/common war relic trackers I know.

The first Gray Ghost are awesome earphones... the Gray Ghost NDT Headphones are the equivalent however with discrete/autonomous volume controls which I need.

Not sure if it's been mentioned in this thread before now, but I recently went through this trying to find a suitable pair of wireless headphones for my Vanquish.

I found one pair of (neckband-earbud style) that were the least expensive "quality" ones with APTX LL capability so the latency wasn't crazy, which actually pair properly with the Vanquish, and show the BT+ (indicating the Low Latency is working).

The least expensive over the ear ones that matched the same capabilities were significantly more expensive (like double the price).

The pair I ended up with were the Sennheiser CX 350BT headphones:

https://www.amazon.com/Sennheiser-CX-350BT-Bluetooth-Headphone/dp/B083W76T8W

These have battery life for approx 10 hours of use. And they support pairing to both the detector and my phone at the same time (so I can use the detector, but still hear calls coming in).

And as said above, they work in true APTX-LL mode, getting the low latency. 

Audio quality seems good, and can detect faint fluty tones from the Vanquish.

(and they had the added advantage of being available locally in NZ)

Hope that's useful to someone.

Cheers!

EDIT:

Also to note, the in-ear buds have the advantage of being super tiny, so they pack up to be small and super portable, AND they can be used with a wide brimmed hat to keep the sun off, which is harder to do with the over the ear kind. (which in NZ is a big deal because the UV here will COOK YOU lol)

      I mentioned these headphones but it's embedded in another thread. I think them worthy of a post of their own with the right tag.
      They're not waterproof or even water resistant, but I'd still use them at the beach. I don't like earbuds, and the one set I tried failed after 3 days.
      I've been looking for something that is on ear or bone conducting, this headphone was released in December 2020. Don't know why I didn't find them earlier:
      Creative SoundBlaster Jam V2.
      Specs:
      Aptx-LL (B+ on the Equinox) 
      Bluetooth 5, Aptx-HD as well
      Can connect to 2 devices, and be used direct wired via USB-C cable
      22 hour purported battery life
      On ear 2" Neodymium drivers
      3.5 ounces
      Noise cancelling (but you can hear ambient sounds like your pinpointer)
      USB-C charging
      Spare pair of ear pads and charging cable.
       
      These headphones are outrageously light, can easily accommodate any head size (they will expand as you use them), and they are loud and have bass boost. After using them for a day they sounded almost as good as my BT-80 over ear headphones which I compare everything to. They paired within 2 minutes to the Equinox. Once paired, put them on, push the large button and hold until you hear a tone. Turn the Equinox on and bam. 
      The only cons I can think of are that the band is a bit uncomfortable (no padding) unless you wear a hat, and they can come off with a lot of stooping. Wrap the band with sticky tape. I wrapped mine with ACU because I like camo. 😀
      They're $39 on Amazon.

      Acabo de ver estos auriculares en aliexpres. No estoy seguro de lo que valen, pero lo comparto por si le interesa un compañero. La verdad es que se ven bien
      Translation from Google Translate: 
      I just saw these headphones in aliexpress. I'm not sure what they're worth, but I'll share it in case you're interested in a partner. The truth is that they look good

      Question:
        Does anyone else have a problem with the ws5 headphones battery going dead while they're turned off? They are updated to 5.21...twice !! 
        Could it be the headphones have a problem or is it the battery? It's certainly not normal.  Thanks!

      Morning all,  
      I have been looking for something that will essentially work like a WM08 (the Equinox wireless receiver) but on the GPX 6000.  Something that can then simply have any type of earphone, earbud, on ear or over ear headphones attached to it.  
      I specifically wish to plug some Philips Sports earbuds into a Receiver.  They sit out of the ear to allow some ambient sound in so you are aware of surroundings.  And don't sit inside your ear like a proper ear bud that can get all sweaty and yuck.  I've used the Philips before and they are perfect for me.  

       
      The supplied Minelab GPX 6000 headphones work great - but I'm not keen on headphones as they are hot and they make it difficult to wear a broad brimmed hat.  I do recognise there are other hat options.   
       
      The non Bluetooth options:
      The Quest kit is great (  http://phasetechnical.com.au/product/quest-wirefree-mate-kit/  )  and  although I know they work really well, they definitely only pair with each other and I do not want to attach a Transmit unit to the GPX 6000 - possibility of EMI, an extra thing to get knocked off, an extra thing to charge and the functionality of a Bluetooth LL Transmitter is already in the GPX so why not use it!! 🤪   
      The Minelab Pro Sonic is too expensive and would need a Transmitter attached to the detector. 
      The Garrett Z-Link - would also need a Transmitter attached to the detector.  
       
      Bluetooth APTX Low Latency options:
      I have ordered the Avantree AS70 as it said they were due for release at the start of June.  But since ordering (4 days ago) that has been changed to the end of July  😤    https://avantree.com/au/as70-bluetooth-adapter-for-headphones   They are the latest version of the Clipper Pro previously mentioned on DP as having worked well.  The Clipper Pro seems completely unavailable now. 
      I like the look of the AS70 and Clipper Pro as they have a good clip that will attach to a shirt, collar, harness or whatever. 
      There are these  https://avantree.com/au/lock-bluetooth-transmitter-receiver-set    but they are a pair and I wonder if the Receive unit will work directly with the GPX or will it only pair with the Transmit unit (it does say auto pairing with each other in the write up).
      Chase Goldman had previously mentioned these as working well:
      TaoTronics 65ft Bluetooth Transmitter/Receive https://www.amazon.com/dp/B076BMT9BY
      TROND Bluetooth V5.0 https://www.amazon.com/dp/B01B4W40VC/       Newer version here     https://www.amazon.com/TROND-Bluetooth-Transmitter-Indicator-Simultaneously-dp-B01K8ANDCI/dp/B01K8ANDCI/ref=dp_ob_title_ce
      I notice the TaoTronics is currently unavailable on Amazon.
      At this stage I may get one of the newer Trond units as that will at least be a back up for my upcoming big trip and may end up being my main unit if the Avantree does not turn up in time.  
      There are a few others mentioned on this site  http://www.aptx.com/  but some look el-cheapo, some are no longer made (the site is not kept up to date in that regard), none of them have a clip to attach to clothing and I am unsure if any of them actually pair with a Vanguish/Equinox/GPX6.  
      Anything that pairs and works well in Low Latency with the Equinox/Vanquish should work well with the GPX 6000.  Would be even happier if my Equinox WM08 just hooked up (shame on you Minelab 😜)
      So my questions, finally!  
      What other brands have worked for people?
      Is the audio quality good?  Manufacturing quality good?  Somewhat weatherproof?
      Is the Low Latency good?   
      Have they paired easily with no issues? 
      What sort of time frame are the batteries lasting for most people?     
      Hoping you good people can share some 1st hand experiences - good or bad - and this can be a one stop resource for others searching for a similar device.  
       
      Cheers, N.E.  👍

      Has anyone tried one of these to waterproof their WM08 module?
