Knomad Posted July 5 Share Posted July 5 I assume the MS-3 headphones use just an ordinary transmitter and receiver, because they don't require Pairing like Bluetooth. So it is likely they are much like some TV headphone systems that are FM systems with limited power. Not to Bash Garrett, Well maybe a little, but I think if the frequency is the same I may be able to find headphones that don't drop out as easy or as much at a Dollar Store.! Listening Garrett -- a $4000 PI Detector with a headphone system that drops out if you are close to the coil, or more than a few feet away.! Really..!!

Steve Herschbach Posted July 5 Share Posted July 5 Speed: 17 millisecond delay (6 times faster than Bluetooth) Operating Frequency: 2.4 GHz band frequency hopping https://fcc.report/FCC-ID/DBDZLYNKMS3000/ Good luck finding them at Dollar Store. My theory is it’s something to do with Axiom being PI since I’ve never heard of drop out issues with any of the VLF models. I've not experienced a single drop out with the Vortex I am currently using with the MS-3. 1 Link to comment Share on other sites More sharing options...

Steve Herschbach Posted July 5 Share Posted July 5 Did not matter too much which side I had the power button on, I still had drop outs. Wide sweeps like I have seem to make it happen more than short sweeps. My fix was use the WR-1 receiver with my Sun-Ray Pro Gold plugged into it, helps a lot but it does not completely eliminate the issue. I do get much crisper audio also with the Sun Ray and dual volume controls, can use my ear buds also for hot weather, just a better way to go. https://www.detectorprospector.com/topic/20746-axiom-wireless-headphone-report-with-options/ 2 Link to comment Share on other sites More sharing options...

Yeah that was a very weak point of the Axiom, being 2.4Ghz WiFi rather than BT drop outs should not occur thus like you Steve I think it had something to do with the Axiom in particular. Of interest perhaps quality game ear buds use 2.4 also for the lower latency and quality of audio over BT. Link to comment Share on other sites More sharing options...
Geotech Posted July 5 Share Posted July 5 Garrett isn't using WiFi, it's a proprietary method that uses the same ISM band as Bluetooth. All of these chips have a TX power output level and the higher the setting, the farther they reach but the more battery power they burn. It's likely Garrett selected a TX power setting that's too low, and it's very possible that PI vs VLF is contributing. We had the same problem when proto-testing the White's V3, on a wide right-hand sweep the audio would drop. We bumped up the TX power setting and solved the problem. The TX power setting applies to the wireless chip in the detector, not the headphones, so even if you could find compatible aftermarket headphones (almost certainly not) it wouldn't solve the problem. 4 Link to comment Share on other sites More sharing options...
phrunt Posted July 5 Share Posted July 5 The Quest wirefree also uses 2.4gHz and is very good and reliable with signal. Link to comment Share on other sites More sharing options...
Knomad Posted July 6 Author Share Posted July 6 Steve, that information tells me the basic problem, like much these days the radio system is Over Engineered and under built.! And as I said at the first release of info for the Axiom, not putting Bluetooth built in is a basic error in marketing, and now we know what they went with is a basic error in engineering.! NO detector should only use Proprietary headphone systems, the Nox 800 had both, why not a detector 4 times the price.! This is a basic Freedom issue to me and others, I want the freedom to use any headphone or other device, and without the separate cost and extra separate charging. I do use a separate Bluetooth transmitter with my other detectors, BUT that is because they never had any king of wireless built in. BTW there are Bluetooth transmitters available on Amazon cheap with plenty fast enough latency at a fraction of the cost of Garrett's, Or Quest. As for Quest, I have tried two of their units and they lasted less than a year, and cost about $140 if I recall, compared to the Amazon sourced ones that have yet to fail after years of use.

Knomad Posted July 6 Author Share Posted July 6 CARL, Any chance a software upgrade could increase that power setting you mention.? Link to comment Share on other sites More sharing options...
