My brother uses the Deteknit Headphones they come with the 1/4 or 1/8 inch plug. He uses these for his Etrac and wishes he would have got the ones with the 1/4 plug because the adapter for the 1/8 plug is always coming loose. They claim 6 hours of run time before charging. This whole setup with headphones transmitter and receiver is only $89.95. My guess the headphones would have to be very inexpensive to be included in this wireless system. My brother says no signal delay and likes this setup, but could have included better headphones and more run time before a charge. These are made either in Egypt or Turkey? The Garrett Z Linc comes with only the transmitter and receiver and require the buyer to use their own headphones, I think this is a plus. Run time before charging 30 hours, which is a lot more time than 6 hours. They advertise a faster response time between the transmitter and receiver. Made in the USA. People who use these swear its the greatest thing since the hand held pin pointer. Just my observation. By the way will be using the Garrett Z Linc this season, if the ground ever thaws out.
