Sony WI-C100

Should last longer than 6 weeks ... Update 6 : 09/09/25 – Purchased 4 Feb 24, they have great sound, excellent battery life and are small enough to wear comfortably while sleeping, but after just 6 weeks one ear stopped working. Took it back to the store 6 Apr 24, they replaced them but again 5 weeks later one ear stopped working. Very disappointed in the reliability of this product. We have enjoyed many Sony products that have lasted more than 10yrs like our 43" Sony TV bought in 2006, STILL WORKING GREAT!

Modern gear ... not impressed at all.

*** update 17/5/24 *** After calling Sony support about the problem she was talked through the "Initialize the headset" procedure that restores the factory settings ... and unbelievably both channels started working again. It will be interesting to see how long this reset works for, however I'm curious as to why a reset would restore a missing channel and whether Sony will produce a firmware upgrade with a permanent fix.

Raised the rating 1 star, we have saved the user guide which shows the Initialize procedure if it happens again.

*** update 27/5/24 *** Sound dropped out again, just 10 days later. Tried the initialization procedure TWICE but this time it hasn't fixed it. Hopefully another call to Sony will either replace them or refund.

Dropped rating to 1 star.

*** update 1/8/24 *** despite repeated contact with Sony support after providing a copy of the Big-W receipt, because the Description for the product only says "Sony Wireless InEar" and does not quote the model "WI-C100", Sony REFUSED to replace it, basically saying the receipt could be anything. So we sent through the Big-W webpage link for the product that shows the Big-W SKU in the description but that still wasn't sufficient to prove we bought "WI-C100" ear phones.

Eventually (24/7/24) I took them back to another Big-W store and they replaced it no questions asked, good support from Big-W customer service. So far the new set has been working fine but we'll see how long it lasts.

We're pretty disappointed with Sony support's attitude ...

*** update 16/12/24 *** and again, L ear stopped producing sound. Full factory reset/initialise has failed to correct, will try to get them swapped out at Big W again, just have to find a store with stock.

*** update 03/01/2025 *** swapped over again at Big W today, a month left on the warranty. We've been trying to find an alternative with similar battery life and a small enough earpiece but that's been challenging. One set she has liked for years is comfortable and has great sound, but when the battery is low a full-volume "BATTERY LOW" wakes her up from her deep sleep, something the Sonys don't do. The search continues ....

Looking at the global Sony website for this product we are not the only ones reporting back that 1 side stops working. Clearly some kind of manufacturing/design fault, but us consumers are expected to suck it up. This page suggests that the listing is monitored by Sony and of course not a peep from them.

*** update 09/09/2025 *** Following my update 3/1/25 mentioning that Sony monitors the review, lo and behold a few days later they disappeared!

So after a few weeks of having to do the initialise over and over, we finally gave up and tossed them. Had originally rated them 5* for value for money but dropped to 1* because now they've now landfill and it feels like tossing $40 down the toilet, plus the cost of a replacement.
