I always enjoy these threads and all input on the topic. Some good info to be garnered.
When it's purely audio that you're relying on to hear anything that the detector tells you, then you definitely wan't it to be the best volume and clarity it can be.
There will always be a few pro's and con's on both sides, but personally I'll always lean towards the headphones given the option, particularly with a machine like the SDC where you want as much volume as you can squeeze from it -without causing lasting hearing damage of course- while still maintaining clarity inside the threshold frequencies. The Sennheisers do that very well for me at my hearing range. I only tried these purely out of interest from many discussions with Heatho prior (there are old threads on the topic from that time) and they did the job nicely. The HD280's just brighten the threshold frequency enough for me while detecting, not to mention you forget you're wearing them due to the lightweight, comfortable fit. The Sennheisers have been my go-to studio drumming headphones for many years now.
The old Koss headphones simply don't cut the mustard in terms of audio quality and isolation compared to many of these aftermarket models.
Back in the day I just ran the little supplied speaker on the 5000 as even then I knew the supplied Koss headphones weren't great. Had I have known then what I know now I would have instantly gone to better headphones or even a good aftermarket booster/speaker combo. Ah well, live and learn as they say.
The biggest pro to headphone use is that they pretty much eliminate those outside noise variables like wind and scraping the coil through leaves and sticks etc. Though it's nice to have the option of a speaker if needed, particularly on those mid to high 30 degree days. It's those times that I enjoy taking off the headphones and just running the speaker module on the Zed when I'm recovering a target. Definitely a nice bit of relief
Later in the year, and purely as another experiment for the Zed and SDC, I will be trying out a set of Shure SE846 in-ear monitors that I use for live stage music. These retail around the $1000 mark and are definitely not for everyday use around the goldfields. (Just found myself having a good chuckle at that sentence!) But, what they do allow and where they will shine is in their capability to adjust fully to all frequencies in 100% complete isolation. Being able to set quickly to high, mid and low ends of the spectrum will be a real treat, albeit a purely scientific one. FOR SCIENCE! :lol:
At the end of the day, we will miss gold with speakers, we will miss gold with headphones and we will miss gold with even the best coils/detectors, but if anything gives you even the slightest advantage over those that have gone before or simply makes the user experience easier or more enjoyable/tolerable (particularly in those nasty, high EMI areas) then it's surely got to be worth a try? :Y:
Kindest regards,

Just to clarify- I have no affiliation or sponsorship with Sennheiser. Not sure that needed pointing out, but worth a mention. I will definitely backup a good product when needed. :Y:
