AptX Low Latency Bluetooth Wireless Headphones for Minelab Equinox 600 800

Description

I have a  pair of used Quest Wire-Free headphones for the Equinox 600 or 800 I no longer need. These are APTX Low Latency that have very little lag time. They work and sound very good. They are missing a rubber plug that covers the charging port as shown in one of the pictures. If you have any questions please feel free to ask, thank you.
The customized, professional grade high sensitive speaker drivers deliver all the details of the signal from the detector.  The high responsive performance helps you find more with no compromise.
> Qualcomm atpX Low Latency technology(HE model) or Texas Instruments 2.4G signal connect to your detector through digital technology.  It offers non-distortion pure audio signal with a minimum delay. You will hear and find the true location.
