I’m not super sure, but 1 year is typically the standard wqarranty period from what I’ve seen. My $2 earbuds from Officeworks, and most anko stuff from Kmart has a year warranty. Some stuff goes up to 2

I’d probably go in anyway and see what they can do for you. JB tend to be pretty alright from my experience. Probably largely to do with them putting like a 90% markup on almost everything they sell unless you get a price beat or try to haggle
