Fantastic Headset/Boomset from Heil Sound. Traded Joe,WD4FGB, for this headset during an IOTA event back in 2013 on Sapelo Island. I love the switch on the side. Certainly was helpful at times. I originally intended to use this with my KX3 but ended up not really ever using it. I did have to put in a special request to Elecraft to work on a firmware update to bring the audio levels up on the KX3 in order to work with the HC6 element (Howard, customer service, and Elecraft team are AWESOME and fixed the issue). Condition is good. Some minor wear on pad covers (you can tell that they have some minor wear with fabric pilling here and there). Joe's callsign is on the metal band still (Sharpie lasts forever). Metal band is still very stiff (from minor use...so it may need to be opened up a bit so it doesn't become a head "vice" after 15mins). No noticeable issues anywhere else on the product. Since this was a trade...I don't have any boxes, adapters, etc. Price: $134 USD (with free shipping via USPS) Terms: Paypal only. Ship to CONUS only. No warranties implied (sold as-is). Contact: k4mtx @ yahoo . com Specs: Contains a fancy switch that allows you to change the phase and move the signal acoustically. Pretty cool actually. More details can be found here: https://www.heilsound.com/amateur/products/headsets/pro-set-elite Savings: Approx. $50 USD plus shipping.

I am fairly certain that its in Sharpie...but you may be able to find something to remove it.
