Hi all
I know this is a very old thread though hoping since the last post there may be some extra info on the topic.
I have had very good results with my SDC2300 since starting detecting this year, usually just using the built-in speaker. However, like others have said here, when determining whether a perceived very faint signal is legit or not, can be hard when the speaker is pointing away from me, or is moving to and fro as well. I have used the new headphones it comes with and a high-quality set of Etymotic HF5 ear bud speakers. Even though they make the signal stable from machine movement, the cables are a pain in the ar5e when moving around in long grass/bushes etc. Don't know how many times I've snagged the cable in something (including harness/backpack) and pulled them out of my ears. Therefore I don't use them much, except when I'm really trying to decide if a faint signal is real or not. (I have had a few cases whether after a minute or so (switching back and forward from setting 3-4&5) I could have tossed a coin on whether the faintest of signals was legit or not... only to err on caution and ended up digging up a deep 2-4 gramer.
Depending on the ground/location I'm at, I usually have the Sensitivity between 3-4 setting (4-5 can make too much of a warbling pitch noise which can hide faint signals) and the Threshold about half way (5-7).
Now, I am really considering buying the PRO-SONIC Universal Wireless Audio System that comes with the SDC2300 adapter cable

I've read some mixed reviews though starting to think, even though they are reasonably expense, they may be as good as anything when you consider the ease of use, technical specs and fit-for-purpose.
Does anyone have any experience with these on the SDC2300 or other detectors, or just some further advice about them?
Cheers,
Crocket
