Came across this piece from the store stock.
Used once for a few minutes but since we didn't do a lot of headphone/portable gear it comes to you as basically a new unit.
Couldn't find the original packaging - but the Resonessence Lab website has all the info you'll need.
If you need further assurances there are reviews aplenty - do your due diligence!
