Sony WF 1000XM4 Left Earbud draining 10 times faster than right

[Thommy]

Like the title states, my left earbud randomly started draining extremely fast.

I suspect the 2.0.1 firmware.

I bought these in Denmark on February 17 last year and now they are essentially worthless as I can only use the left earbud for about 40 minutes.

 

I have since moved countries to Japan, so I don't know what to do about warranty now 😞

I have a attached pictures showing the battery drain using both over about 1 hour.

Sony please respond.

In the end I sent them to the Sony service centre at my expense. Their repair estimate is £34. They say they have sent for the parts and I am now waiting for the repair to be done. It has a 90 day guarantee. We'll see what happens.

I found vides about replacing the battery, had a go myself but I messed it up so left earbud is now dead. At least I tried. I will get new Sennheser earbuds. Sony is dead to me. Forever.

I'm unlikely to ever buy any more, but hoping for a £34 repair these will be kept alive for a while longer.

I have exactly the same issue.

I've complained with Sony Italy and since i'm out of guarantee (for 3 months), i've got to take my earphones to a repair center, at my own expense, without even knowing how much it will cost.

Absolutely useless response from Sony, neither acknowledging this is a recurrent issue, nor taking accountability whatsoever.

I find it outrageous that a EUR 280 pair of earphones -top of the line- are designed to become obsolete just after the guarantee expires. Great sustainability standards.

Well done Sony. You lost another customer.

I know this is a common issue, and I hope more people take the time to share and complain. If not, Sony gets away with screwing us.

This doesn't work

[PaulGUden]

I bought mine from Amazon.es. Had them repaired in the UK for £34 - unnecessary but not extortionate in the end. Back in Spain now and they're fine (so far).

Where did you get this done, Paul?

[PaulGUden]

Hi, it was the Sony Central Service at Pencoed Technology Park in Pencoed. If you contact them they send you a service request form to fill out and post with the ear buds. That cost me £7.95 with Royal Mail tracking etc. Seems to be working as new for the time being.

Hey all, they most likely will need a repair, try to contact the support team of japan to help you.

It is a shame that SONY is robbing the customers.
