I ordered a pair of chefphones CP3 TT headphones for my Minelab E-trac months ago as it looked like an awesome set to use which had great reviews. Sadly due to the postal strike, the headphones never arrived (until yesterday!) and I no longer own an E-trac and my Fisher CZ21 does not have interchangeable headphones, so I cannot use these. Therefore I am selling them brand new, never been used for R850 including postage.
Here is the description of the headphones from the chefphones website:

After the development of the Chefphones CP1 with its quality mellow tones and the CP2 with their sharp clear signal response, we turned our attention again to listening to what fellow Detectorists were saying about the other well known headphones on the market and just how we could better them and solve some of the problems that people were having time and time again.
And now they are ready the CP3 TT metal detecting headphones. Made to the our same high regard for detail, the CP3 has employed speaker elements especially imported from the USA for use in the CP3.
Tested on all the leading makes of metal detector the new TT has proven itself to be the real chameleon of the headphone world adjusting its impedance and output to the needs of the particular detector being used.
While being superb with all makes and models, the TT come into its own when used with the multi tone machines, delivering the sound that the detector manufacturer intended you to hear.
The CP3 comes with a detachable and easily replaceable 4.5m coiled cable. Mode/kill switch, making them usable with most makes and models of detector.
And not forgetting the Chefphone lifetime guarantee (excludes lead). If you intend using the CP3 with the CTX 3030 please specify at checkout.
