I have both of my FBS detectors set up with Bluetooth wireless APTX Low Latency transmitters and APTX Low Latency headphones and earbuds. I purchased the transmitters on Amazon for $22.09 (iTeknic) and both the earbuds (MacaW T1000 Pro) ($23.00) and (1Mii) $34.99 long range Bluetooth APTX Low Latency wireless headphones. One (about $3.00, 8 inch 3.5mm or 1/8 inch male to male right angle cable and a ( about $2.00) 6.35mm or 1/4 inch male to 3.5mm or 1/8 inch female headphone stereo audio connector. I put a strip of velcro on the side of my battery compartment, closest to the 1/4 headphone jack and the other strip of velcro on the back of the transmitter. That way I can take the transmitter off of the detector to charge it. I have been using this setup for about 4 months and they work great! No more cords! I can detect for at least 8 hours on the charge. It also works with my Equinox Bluetooth headphones. You must get the APTX Low Latecncy transmitter, earbuds, and headphones or you will have lag time in your signal response when going over a target.
