## Product: Sony WF-1000XM5 Earbuds
**Brand:** Sony

Ear tip size seems like a small thing, but it makes a huge difference with the [WF-1000XM5](https://shopsavvy.com/products/Ygp0PNY1Re4FHR7s3Ulb). Wrong size = weak bass, poor ANC, and earbuds that won't stay put. Right size = everything works as advertised.

## What Sizes Come in the Box

Sony includes four sizes:
- **XS** (Extra Small)
- **S** (Small)
- **M** (Medium) - this is what's already on the earbuds
- **L** (Large)

Most people land somewhere between Small and Large. The pre-installed Medium works for many, but don't assume it's right for you.

## The Fit Test Is Actually Useful

I know, running a "fit test" sounds like overkill. But this one is worth doing. It takes 10 seconds and can dramatically improve your experience.

Open the Sony app, go to System, find "Optimal ear tip," and run it. The app plays a sound and measures how well each earbud seals your ear. If it says you have a poor seal, trust it. Your ANC and bass are genuinely suffering.

The test checks each ear separately, which is helpful because (fun fact) your ears are probably slightly different sizes.

## How to Tell Your Tips Are Wrong

**Too small (most common issue):**
- Bass sounds weak and thin
- Noise cancellation doesn't seem that impressive
- Earbuds shift around or fall out
- You hear way more ambient noise than you expected

**Too big:**
- Earbuds feel uncomfortable or tight
- Your ears get tired quickly
- Hard to push the earbuds all the way in

## Finding Your Size

Start with the Medium tips that come installed. If the fit test says your seal is poor, go up to Large. If Medium feels too tight, try Small.

Here's something people don't realize: you might need different sizes for each ear. Using Large on one side and Medium on the other is totally normal. Use whatever combo works.

## Third-Party Tips Are Worth Considering

The stock Sony tips are fine, but some people get better results with aftermarket options:

**Memory foam tips (Comply, etc.)**: These squish down when you insert them, then expand to fill your ear canal. Great seal, really comfortable, but they wear out faster.

**Premium silicone (SpinFit, AZLA)**: Different shapes that might fit your ears better than Sony's design.

If the stock tips just aren't working for you no matter what size you try, a  set of aftermarket tips can make a big difference.

## Keep Them Clean

Dirty ear tips can actually affect the fit test accuracy. Clean them occasionally (soap and water is fine), and make sure they're fully dry before putting them back on.
