Don't Buy Sony WF-1000XM4 Earbuds Before You See This
Critical warnings about battery degradation, fit issues, and better alternatives you need to know.
Before You Buy...
Before you spend $280 on Sony WF-1000XM4 earbuds, there's something you need to know. Thousands of owners have discovered battery failure and fit problems too late, and the manufacturer downplays these issues. Read this before you buy.
The Sony WF-1000XM4 earbuds are widely praised for their industry-leading noise cancellation and superb sound quality. However, many buyers don't realize that these earbuds come with significant hidden pitfalls: rapid battery degradation that can render them unusable within a year, foam eartips that wear out quickly, and a lack of essential features like multipoint Bluetooth (added later via firmware but initially missing). In this guide, we'll reveal what Sony doesn't tell you, warn you about the real costs, and show you better alternatives on Amazon that solve these issues—helping you make an informed choice and avoid a costly mistake.
🔍What They Don't Tell You
Sony markets the WF-1000XM4 as premium earbuds with best-in-class ANC, but they don't highlight that the battery life can plummet to under an hour after just 12-18 months of normal use. This is a widely reported issue on Reddit and Amazon reviews, yet Sony's warranty only covers 1 year. Additionally, the included foam eartips are comfortable but degrade and lose their seal within a few months, forcing you to buy replacements ($15-$20 every 3-4 months). Unlike some competitors, these earbuds do not support true multipoint Bluetooth out of the box (though a 2022 firmware update added it to select models). These are critical issues that directly affect your long-term satisfaction and wallet.
⚠️Critical Warnings
⚠️Severe Battery Degradation Within 12-18 Months
IMPORTANTMany users report that the battery life of the WF-1000XM4 drops from 8 hours to under 1 hour after about a year of use. This is due to a known battery defect that Sony has acknowledged but has not offered a free replacement program. If you're out of warranty, you'll have to pay $100+ for out-of-warranty service, or buy new earbuds.
Affects: Most buyers
⚠️Foam Eartips Wear Out Quickly and Need Frequent Replacement
IMPORTANTThe included foam eartips are comfortable but lose their shape and seal within 2-3 months. This compromises noise cancellation and sound quality. Replacement foam tips cost $15-$20 per set, adding significant long-term cost.
Affects: Most buyers
⚠️Limited Multipoint Bluetooth (Initially Missing)
IMPORTANTWhen launched, the WF-1000XM4 lacked multipoint Bluetooth, meaning you can't connect to two devices simultaneously (e.g., phone and laptop). A later firmware update added multipoint, but only for select devices and with inconsistent performance. Some users still experience connection drops.
Affects: Most buyers
⚠️Fit Issues for Small Ears
IMPORTANTThe WF-1000XM4 are larger and heavier than many competitors. Users with small ears often find them uncomfortable or unable to get a secure fit, leading to the earbuds falling out during exercise.
Affects: Most buyers
⚠️No Official Water Resistance Rating for Earbuds (Only IPX4 for Case)
IMPORTANTWhile the case is IPX4 (splash-resistant), the earbuds themselves have no official water resistance rating. This is unusual for premium earbuds at this price. Sweat or rain can damage them.
Affects: Most buyers

- ❌Buying without comparing to newer models like WF-1000XM5

🌟Better Amazon Alternatives
Instead of dealing with the issues above, consider these better alternatives available on Amazon:
📝Bottom Line
The Sony WF-1000XM4 are excellent earbuds – when they work. But the battery degradation issue is a real dealbreaker for long-term ownership, and the foam eartips add ongoing costs. If you're still considering them, be prepared for potential battery replacement or invest in an extended warranty. For most people, however, the alternatives above offer a better, worry-free experience. The WF-1000XM5 fixes many issues if you want to stay with Sony. Apple users will love the AirPods Pro 2, Android users should look at Galaxy Buds2 Pro for value, and Jabra Elite 7 Pro are a solid budget option. Bottom line: don't buy the XM4 without understanding the risks – choose one of our safer alternatives.
