After recieving the new Deteknix HD Deus headphones this morning from Nenad (Phasetech), I was very eager to get out and give them a good workout, especially after hearing the glowing reviews that these are receiving from abroad. Needless to say they were right. Great build quality, extremely comfortable and lightweight, loose enough to not leave you with a headache after an hour, but firm enough to not have them slipping off your head every time you bend over (hello Koss). Click the WS4 puck in place and away you go, simple as that.
The audio is spot on for me, and that was my main concern with any aftermarket headphones on offer for the Deus, including this one. Many full muff headphones for the Deus tend to lose that crisp clear audio that the WS4 backphones are renowned for, including my Chefphones from the UK which tend to sound quite "muffled".
Whilst the Deteknix headphones are full muff units, noise isolation apparently wasn't one of its better features going by the overseas reviews/comparisons. As far as I am concerned that is a good thing. They do offer a good balance of noise isolation whilst still having some connect with the outside world, the audio is plenty loud enough to hear over any ambient noise, plus you can talk to your detecting buddy without having to remove them all the time. I do prefer to know what is going on around me when detecting, hence not really a big fan of using headphones that act more like safety ear muffs.
The ear cushions are nice and soft vs the firm plasticky feel of some - after a while I pretty much forgot I was even wearing them they are that comfy. Also included is a 3.5mm or 1/8" jack port with a rubber O-ring sealed plug to keep out moisture, hence you can connect directly to the Deus remote should the WS4 go flat - the cable is also included.
In keeping with the XP line of thinking where all Deus parts are replaceable, these headphones also offer fully replaceable parts - a great move by Deteknix.
Lastly the headphones come with a nice drawstring storage bag to help against further soiling or scratches. As for how rugged these headphones are, time will tell I guess, will leave that for an update down the track after some more detecting hours.
These are so new to the OZ market that they have yet to appear on the Phasetech website, so if interested, get in contact with Nenad and I'm sure he will look after you.
