Hello, for the last year I've been using Sony's WF-1000XM4 Earphones, and during warranty period had almost no complaints to product. But last month or two - coin flipped. Earphones started overheating, for no reason. Due to overheat battery lifetime decreased several times. If usually I had 5-8 hours of playback time, but now - right earphone ~40min, left ~ 60-70min (time may very).

Factory resetting or any troubleshooting process didn't help.

I've tried to contact Sony Ukrainian call centre, or service centre, but didn't get any constructive response. Every proof I shared was ignored. Every link I've sent was denied.

Sadly seems that on Sony Ukraine's opinion warranty period = product life span

Service centre says they would not help because headphones are out of warranty, although this problem is not on my hands, just a defective batch.

Don't know why, but still have last hope for some miracle, such as out of warranty replacement, or something like that.

Anyone got any ideas what should I do, to save earphones and money spent?

@TheGOAT The outcome was... interesting. @dietervonkhan was kind enough to send me anonymised screen-caps of his e-mail exchange with Sony specifically mentioning the replacements that they sent to him - Sony CRO denied that this had ever happened! They also said that they didn't give him a free repair service, despite the e-mails saying that they had.

They flat-out refused to replace the WF-1000XM4 buds - it was very clear they weren't going to budge on that. However, eventually they agreed to send me, as an "exceptional gesture of goodwill", a £100 discount code for the Sony online store. So I bought a pair of the new WF-C710N buds to replace the f**ked WF-1000XM4, and they'll be the last Sony product I ever purchase.

The lesson to learn here is to keep pushing, I guess! Eventually they'll roll over, at least partially, and offer you something just to shut up and go away 🤣
