Sony True Wireless Earbuds with Charging Case, Silver, WF1000XM4/S

Sound quality is great, fit is great, battery is trash. I don't use these that often (every 1-3 months) but the last time I did the battery on the right earphone went from 35% to 0% in about 5 seconds. After repeated charging the right earphone is essentially unusable. Since Sony doesn't seem to have any way to contact them (other than via phone?), I'm leaving this review as per their request.

These worked well but did not have the promised best sound. After not using them for some time for fear they would be lost as they never fit properly, even with the earpads provided, I decided to give them another try. After fully charging them with the provided cords the, the left ear dropped the charge within minutes (100% to 0% in under 5minutes). Went online and read that it might be a firmware issue. Tried updating to the latest but was unable to do it in one try because of the draining battery. When I was able to finish the update, the battery went from 60% left and 75% right to 0% both. Even after resetting the battery now drains not in 5 minutes but on the left, almost immediately, on the right I may get 10 minutes out of it. Very saddened by this as they are expensive and seem to work poorly, much more so than the cheaper Monsters I wound up buying to replace these.

I purchased the Sony WF-1000XM4 earbuds about a year ago, and I am already experiencing severe battery degradation. Specifically, the left earbud drains rapidly, even with active noise canceling (ANC) and sound enhancements disabled, battery last for less than 40 min from full charge. It is disappointing because the audio quality is excellent, but the device is becoming unusable. To make matters worse, the warranty support has been completely unresponsive.

This is my 5th year using them and don't plan on changing them, they are awesome!

They felt too heavy and uncomfortable to wear. And they stopped working after an year. Never expected this from Sony.

Do a search online and you will see that this model has a horrible batter life problem. I can go from 90% battery to shut down in 15 minutes. Sony knows of this issue but didn't do anything about it because the issue would arise after the warranty expired.

I purchased both the Sony WF-1000XM4 and Sony WH-1000XM4, only to encounter significant issues with each. One device has a persistent battery problem after a firmware update, while the other unexpectedly emits a high-pitched whistle directly into my ear. It's disheartening to witness such drawbacks from a renowned company like Sony, which has now plummeted to the bottom of my preference list. Regrettably, I've lost faith in Sony, and as a result, I won't be considering any of their products in the future. My trust in the brand has been eroded.

This is my second pair in two years that experienced a battery drain an issue with one of the earbuds. This pair was the warranty replacement for the first that failed within the warranty period. Unfortunately the replacements don't come with a one year warranty. The battery drain issue is well documented and there is no known fix for the issue.

I'm not happy with product. They were very good to start but I'm having severe battery drain issues and the case no longer charges to a full charge which means the headphones won't receive full power. With the cost of these I'm very disappointed in the quality.

Battery degradation is a serious problem. These headphones sound amazing, the battery life and features worked well for a year. Battery life has suddenly dropped to the point of being unusable. Sony will recommend turning features off and initializing if that doesn't work. The batteries are replaceable, which surprised me. Still, these are far to expensive to only last 18 months before needing new batteries.
