why would Studio Headphones be restricted via gsp

[123-butcher01]

Hi sold my

beyerdynamic DT 770 PRO Studio Headphones sent them through GSP now they've been pulled at litchfield under Dangerous Goods Review and classed as Undeliverable

any idea why, i think i listed them in the right category (if i have listed correctly  i'd have thought ebay would have stopped me listing using the GSP.).  I'm presuming it's something to do with electronics !

and is that the last i'm going to see of them and the money, once i have to refund them.

(i'd already sold them once and the buyer never paid, though they'd have been pulled then as they would also have been sent via GSP).

Thanks

"s that the last i'm going to see of them and the money, once i have to refund them."

Unfortunately sellers should know how services they use work.

Things are changing fast but, previously [and possibly even now] you would get to keep the money and Global would refund the buyer.

plpmr thanks for your input
''Unfortunately sellers should know how services they use work.''
I think i have the ''general gist'' of how it works as in once it's left there it's down to them, but it hasn't left there or been broken by them supposedly it dangerous goods which i can't see why and i can only see that someone's going to say i shouldn't have sent it to them in the 1st place, although i can't find anything anywhere to say it shouldn't have been in fact now i've looked it does say that ebay would flag it when listing (which is what i suggested in my post)if there was a problem with using the GSP
So i can't see them refunding the buyer and i keep the money. (but i hope you are right)
