I have a brand-new, still-in-box set of wireless Bluetooth aptX BT80 headphones for sale, made by ZZSY. These phones are identical to the Minelab Bluetooth headphones that come with the Equinox 800, EXCEPT this version does not include the aptX low-latency codec; they instead have the regular aptX codec (i.e. faster than regular Bluetooth, but not as fast as the aptX low-latency codec). I removed them from the box only to ensure proper functioning/pairing. $39 shipped/PayPal.
