Useful Background Information On Low Latency Wireless Audio Accessories For Metal Detectors

Chase Goldman · February 27, 2023

This topic often confuses people and because the details are hidden within specific detector threads people are not aware of nitty gritty details that can help you select the right 3rd party accessories to pair with the wireless audio capability of your detector.

First post will provide a link to a great article that provides some background information on BT Audio and explains and tries to clarify some of the terminology that gets thrown around which tends confuse people when they are looking for compatible low latency wireless hardware that will work with their detector:

APTX-LL Headphones, Earbuds, and Receiver/Transmitters that work with APTX-LL compatible detectors (ML Vanquish; ML Nox 600/800; Nokta Legend). Note that the Receiver/Transmitters can be plugged into the headphone jacks of many detectors that lack APTX-LL transmitters (including the new ML Xterra Pro; Nox 700/900 and Manticore detectors that use Bluetooth LE with no third party wireless headphones available) so you can use these BT APTX-LL headphones and earbuds with them.

Earbuds (note that "true wireless" APTX-LL earbuds and APTX-LL wireless bone conduction phones appear to be unobtanium right now):

Legacy Buds style slightly Aukey B80 Phones are available here:

These are expensive but high quality:

These are reasonably priced and have good audio, I have the silver ones but only green are still available for purchase though they are currently out of stock:

Finally, in budget category there is the following - I have not actually verified that these will pair up in APTX-LL mode with the Nox 800 but they should work based on the explicit APTX-LL specifications listed. I also have no idea on actual sound quality. But at $20 plus a 40% off coupon. It's hard to go wrong with these (pick up a second pair for backup) if they pair up in LL mode AND have half way decent fidelity.

My personal favorite are the following - but they are more bulky because they have a loudspeaker to create a personal sound space near you head without the earbuds, but you can also shift to earbud mode if desired. They have AMAZING audio quality and stereo separation in both loudspeaker mode and bud mode. Note that they are not water resistant and need to be protected from direct water impingement. But that's the beauty of wireless, if its raining, you can hide these under your rain gear easily and they will still work well.
