The WF-1000XM6 comes with four sizes of eartips (SS, S, M, L), but fit is a common concern. Here's what you're getting and what to expect.
What's in the box:
Sony uses their hybrid "Noise Isolation Eartips" from the XM4 era (2021). They're polyurethane foam with a softer outer coating—meant to combine foam-like isolation with better durability.
The fit issue:
Fit is the most common complaint about these earbuds. The tips aren't quite foam and aren't quite silicone. They're stiffer than expected, and some people find them uncomfortable after an hour or two.
Getting a good seal can be frustrating. The Sony app includes a fit test that plays tones and detects sound leakage. Many users fail it multiple times before finding the right size and insertion angle.
What reviewers say:
Multiple professional reviews mention fit as a weak point. The consensus: the earbuds sound incredible IF you get a proper seal, but achieving that seal requires more effort than competitors.
Apple's AirPods Pro 3 tips get praised for comfort. Bose uses shallower tips that don't insert as deep. Both are generally easier to fit than Sony's approach.
What you can do:
Aftermarket tips work great with the WF-1000XM6:
- Comply memory foam tips (comfort-focused)
- SpinFit silicone tips (secure fit)
- Dekoni Audio tips (premium option)
Many users who disliked the stock tips love the earbuds after switching.
Design improvement:
The earbuds are 11% smaller than the XM5, which helps some people. But the tip design is unchanged, so expect similar fit challenges as previous generations.
Budget an extra $15-20 for aftermarket tips if comfort is a priority. Compare prices on the WF-1000XM6.
