It doesn’t matter if you’re someone who enjoys running, weight-lifting, or just delights in a casual stroll down the elliptical, because surely, you’ve already heard about Jaybird and their earbuds. The product that kickstarted Jaybird’s wireless in-ear buds innovation was the Bluebuds X from the year 2012; and after six years, we now have the Jaybird X4.

For years, Jaybird has continuously been the leading company for Bluetooth fitness earbuds. And one of their most notable products is the Jaybird X4 which surely blew their competitors away.

Last year, the company released their true wireless Run which was good too; so today, we’re going to check out the X4 and see if it’s really just as good or better than the other devices from Jaybird. Let’s take a look at what’s included in the package for these earbuds.

The Product

Jaybird X4 Review

When it comes to the X4, it all starts with the design. The company did not recreate the wheel with this device since they saw what worked for their X3 and simply made improvements. The X4’s design isn’t all revolutionary, yet goes a long way in establishing the company as a major player in the market of Bluetooth earphones.

The improvements and enhancements come from the gel-like ear tips that are really comfortable. They also included a Speed Cinch cord control system which is really very useful and convenient. Honestly, it makes us wonder why this specific element didn’t exist years ago.

As for the X4’s overall design, it was carried over from the previous device; thus, having a slim profile for the earbuds, a flat cord, as well as an ultra-light remote. Here, the most noticeable design change would be on the speaker tips. Instead of the regular aluminum finish, the company made use of the durable aluminum material yet included a nice flair of color.

The company also ditched the traditional Jaybird ear fins that come with a honeycombed inlay. Instead, the X4 took the flexible ear tips from the Freedom 2 which adds more comfort to your listening experience. These are made from a flexible gel material which is also utilized for the ear tips, leaving both parts easy to contort and perfectly take the shape of your ear.

The company also included their proprietary Comply Ultra foam tips, though personally, we prefer the silicone ones since they feel more comfortable especially during prolonged use. However, the foam tips are just as good, so it’s really just a matter of preference.

The fit of the X4 has also been greatly improved and this is all thanks to the inclusion of the redesigned wing and tip options. Another excellent improvement would be the cord management system which is more convenient for keeping things neat and organized.

The device also comes with wings plus foam and silicone tip options that come in different sizes.  As for the Tic Pods like in almost all wireless earbuds, come in a nice compact carrying / charging case which appears just like a pill bottle. It also has a short strap made of silicone to secure the case to your key strap or belt loop.

The case isn’t really as small as the usual cases for earbuds, but it sure fits perfectly in pockets, and we’re talking about pockets of women’s skinny jeans so the case is still considered small.

Using the Product

Every X model from Jaybird has undeniably excelled in performance and sound quality. With that, the company continues the momentum with their X4 earphones. It promotes a finely-balanced soundstage that can handle mids and lows adequately.

The sound quality didn’t change all that much but we can definitely say that the sounds it produces are outstanding. Audio coming from the X4 was great from the day we tried out the device. It offered an adequate mix of clarity and bass for everything that we listened to.

If you’re planning to fine-tune your audio experience, you’ll find a couple of EQ settings that are fully customizable in the Jaybird My Sound app.

The company claims that the X4 can go for 8 hours of continuous playback and we did experience that; but surprisingly, there were certain instances when our listening experience went even close to ten hours which is pretty amazing since it exceeded our expectations. With that, it only means that you’ll be able to get a whole week of working out before having to refuel your earphones.

We also tried using the X4 for a couple of calls and the results were good. The person on the other line was able to hear just as clearly as we did; both ends were loud and we didn’t need to bother raising the volume which is very convenient especially when you’re out.

Connection strength was pretty average but we didn’t have any issues; we didn’t even experience any skips despite running or walking around. Also, it was a true waterproof device since it performed well even while running under the rain.

The sounds were just as perfect as it was when we used them during a normal sunny day, and it still offered loud and crisp sounds that were perfect.

As for the control module, it features three buttons that all worked perfectly fine. We didn’t have any issues reaching these while running, especially when we needed to skip between tracks or adjust the volume.

Overall, we give the Jaybird X4 two thumbs-up for its excellent performance, durability, and audio quality.

Conclusion

In the X4, Jaybird solved some of the biggest issues that people complained about in the company’s previous models. With that, we really appreciate Jaybird for listening to their customers’ feedback. In fact, there’s a lot of improvement in these earbuds.

One great thing is its waterproof feature since it can now be submerged into water for several minutes. As expected from Jaybird, the sound quality got better too. In fact, it’s superior and we were able to customize our audio via the Jaybird app, so everything was just perfect.

There are a lot of options in the market but if you want the best headset for workout and adventures with excellent quality and sounds, then the X4 from Jaybird is the best choice for you. In terms of sound and functionality, this definitely meets everyone’s needs.
