I purchased headphones from https://www.ozbargain.com.au/node/422297 late last year (so still within 12 months warranty)
For the last month or so they've been increasingly choppy in the audio. It seems to happen even when the phone is less than a meter away from the headphones.
I reached out to C.O.W. but got no response. Looks like they don't operate anymore.
I reached out to eBay - they refuse to do anything (not surprising). Their solution was to just wait forever until the seller responded or (presumably) my warranty expired. I get that they aren't the seller but they're making a decent amount of money given they take zero responsiblity or offer any support.
I contacted Sony who agreed there was a fault, but didn't recognise C.O.W. as a legitimate reseller.
Per the first comment in the post, someone said they'd had an issue with exactly this. I took the response from smoo7h at face value and, to be honest, didn't really think it would be an issue for an australian company to get a return anyway for warranty.
The question I guess now is there anything I can do? PITA to lose $228 when 3 companies were involved and none are inclined to help.
Grey import - Sony Australia would be in serious breach of contract with their distributors if they were to step in.
The only avenue you can pursue with a grey import is with the seller themselves. In many cases, the sellers aren't in Australia so that may be futile. Worse still is if the seller is insolvent.
You may be able to squeeze something out of eBay if they have some kind of buyer protection.
