That "poor seal" warning in the app? One of the most common complaints about the Sony WF-1000XM6. And one of the most fixable.

Here's the thing: the seal between your ear tips and ear canal is everything. Bad seal = weak bass, pathetic noise cancellation, and that unsettling feeling that your earbuds might fall out. Good seal = what you paid $330 for.

Start with the obvious stuff

Try different tip sizes. Seriously. Most people grab the medium tips that come pre-installed and never try anything else. But your ears might need small or large. Or—here's the kicker—different sizes for each ear. Most people have slightly asymmetric ear canals.

Improve how you insert them. Pull your earlobe down and back with one hand while inserting the earbud with the other. This opens up your ear canal and lets the tip seat deeper. Then let go of your ear and give the bud a slight twist to lock it in place.

Clean your tips. Earwax and skin oils accumulate on silicone and break down the seal over time. Wipe them down weekly.

When silicone tips just don't cut it

Some ear canals just don't play nice with silicone. If you've tried all the included sizes and still get the warning, foam tips are your answer.

Comply Foam or AirFoams Pro are the go-to options. Memory foam compresses when you insert it, then slowly expands to fill the unique shape of your ear canal. For a lot of people, this is the magic solution.

One more thing

Sometimes the app is just being overly sensitive. If your noise cancellation actually sounds great and bass is full and punchy, the seal might be fine despite what the app says. Trust your ears.
