Sony WI-XB400 Wireless Headphones 2020 Updated Review

About Sony WI-XB400 Wireless

The Sony WI-XB400 EXTRA BASS Wireless in-ear headphones are decent budget earbuds for everyday use. Although they’re marketed towards fans of bass-heavy genres, their overall sound profile remains relatively well-balanced, without any hint of booziness.

They provide a fairly stable fit that shouldn’t fall out during exercise, and they have a good battery life that should last all day. Unfortunately, they’re not compatible with Sony’s Headphones Connect app for customization and their noise isolation is rather disappointing. Nonetheless, they’re a good choice for those looking for a basic pair of wireless headphones with an extra kick of bass.


Before we take a deep dive into our review, let’s take a look at what comes with the WI-XB400. Here’s what’s in the box:

  • Earbuds
  • Soft fabric carrying bag
  • USB-C charging cable
  • 3 extra sets of ear tips

These earbuds have a wired Bluetooth design. This means that there’s no wire connecting the earbuds to your phone or iPod, but there is a short cord connecting the earbuds to each other. This cord serves two purposes: first, it supports the battery packs, allowing for longer life than truly wireless earbuds.

Secondly, it allows you to easily take one or both earbuds out and let them hang. This is a useful feature when you’re going through a checkout line and you want to take an earbud out to make the transaction.

The earbuds themselves are on the large size. This accommodates beefy 12mm drive units, which we’ll talk about in a minute. However, it makes them too fat for people with smaller ear canals. Using the smaller ear tips can help alleviate this, but at the end of the day, we’re talking about an unusually wide set of earbuds.


  • Light and portable.
  • Good battery life.


  • No app for customization.
  • High latency.

Sony WI-XB400 Wireless Audio Quality, Performance and Battery Life

Sony WI-XB400 Wireless Audio Quality, Performance and Battery Life

The real reason to invest in these headphones is for their sound quality. Specifically, the superior bass response. The problem with bass quality is that it’s inherently limited by the size of your speaker driver. The smaller the speaker, the less bass it can produce. That’s why even the best compact earbuds oftentimes sound like a knockoff pair of Chinese headphones when it comes to bass quality.

As a result, we were excited to get our hands on a pair of earbuds with a 12mm driver. Wow! The bass is superb, much better than other, compact earbuds. Of course, you’ll need to temper you’re expectations. We’re still talking about a set of earbuds, not speakers with room for a proper sub-woofer. Still, the bass is excellent for a pair of earbuds.

The XB400 makes this easy. It charges via a USB-C cord, which plugs into the right-side battery pod and fully charges both battery pods in about 3 hours. When fully charged, it offers 15 hours of listening time under normal conditions.

These earbuds also won’t leave you high and dry if you suddenly find yourself with a dead battery; they offer a 10-minute quick charge feature that gives you an hour of listening time after just a few minutes of charging.

What Are Some Alternatives?

Of course, just because you want a quality pair of Bluetooth earbuds doesn’t mean that the Sony WI-XB400 is the right pair for you. Maybe you want to ditch the behind-the-neck design for a truly wireless experience. Or maybe bass response is less important to you than a small, comfortable fit?

We’ve reviewed many sets of earbuds over the years. Here are a few recent entries we think might be up your alley:

  • The TronSmart Spunky Pro. These wireless earbuds offer the best bass quality you’re likely to find in a set of buds this small. If small size is a winning feature for you, it’s hard to go wrong with the Spunky Pro. That said, with the drive unit taking up as much space as it does, the small battery will limit you to a maximum 3 ½ hours of music.
  • The Axloie Magic. These tiny earbuds are another solid choice for anyone whose ear canals run on the smaller side. They’re designed for a secure fit, and feature easy, one-touch operation for phone calls and cycling through your playlist. While the battery life is limited, they come with a portable charge pack that offers a total 130 hours of playtime. On the downside, the sound quality isn’t the best.
  • The Axloie Attitude XP9. Like the Magic, these earbuds include a charge pack that provides enough juice for 130 hours of playtime. That’s a lot of power, but what makes these beefy buds impressive is their underwater performance. They’re rated to keep on working down to 33 feet of depth. That’s enough for swimming or diving, although you’ll experience the same humdrum sound quality as the Magic.

Final Points

Final Points

They’re certainly not a disappointment, and that’s saying a lot when you consider how much effort Sony puts into building anticipation for their gear. That said, whether or not they’re worth the price depends on what you’re trying to do.

On the one hand, WI-XB400 is fantastic in the sound department. For jogging, hiking, or everyday around-the-house wear, it’s hard to beat the powerful, driving bass you’ll hear from these buds. They’re also reasonably comfortable, and they offer enough battery life to wear them all day without the need to carry any accessories.
