For many people, a pair of headphones are an essential part of their workout. Between music, audiobooks, podcasts, and even videos, exercisers have no shortage of things to keep them engaged with their routine and get into the groove. However, not all pairs of headphones out there are suitable for hitting the gym.

Wired headphones often get in the way of intense workout routines, meaning that wireless options can be incredibly appealing. However, that's not enough to make an excellent pair of workout headphones. A comfortable fit and sound quality are just some of the qualifications that you should consider when looking for the latest addition to your workout gear.

Jaybird's X4 headphones are the latest iteration in the company's X line of products, and this model has seen some upgrades from the X3 version that came before it. But are these worth the new investment? Our Jaybird X4 review has all the details you need for an informed purchase.

The Jaybird X4 headphones are the latest iteration of Jaybird's X series: a line of wireless, in-ear headphones meant for athletic and workout use. They operate through Bluetooth and can connect to up to two devices at once, as well as multiple platforms. While some of the changes in comparison to the X3 model from the same series, these little tweaks can actually make a substantial difference.

?How It Compares

Putting Jaybird's X4 headphones against the previous X3 model doesn't show too many changes overall. However, the available upgrades are undoubtedly worthwhile, such as the waterproofing, the easily adjustable strap, and just the overall build make the X4s a worthy upgrade for anyone that loves their X3s.

As mentioned, though, the X4s are not the cheapest pair of sports headphones on the market. Yes, you are paying for the quality, but there are plenty of other options out there, such as OnePlus Bullets Wireless headphones, which rival these earbuds at a lower cost for anyone wanting a cheaper investment.

And even though most people don't go looking for sports earphones expecting the highest possible level of sound quality, the V-Moda Forza Metallo Wireless headphones have much more precise sounds without the need to tweak the EQ if you're an audiophile that wants nothing less than the best.

So now that we've reached the end of our Jaybird X4 review, what's our final verdict?

Overall, these headphones are an excellent option for anyone looking for the right pair of earphones for working out. The sound quality is a step up from some cheaper options, especially once you adjust the EQ settings, and the extended battery life, adjustable strap, and customizable earpieces and fins ensure you have a comfortable fit, no longer how long your exercise routine may be.

The wireless range is wide enough so that you can place your audio source out of the way if necessary, and the IPX7 waterproofing makes these suitable for those who take their workout outside. Anyone looking for audiophile quality headphones or a pair ideal for making calls with others might not feel satisfied, but that's not why Jaybird has made the X4s.

At the end of the day, Jaybird's X4 headphones make for a worthy upgrade to their predecessors that are reliable to use, convenient to carry around with you, and suitable for a multitude of workout conditions—and there's not much more you can ask for from a pair of sports earphones.

Our Jaybird X4 review awards these sports headphones 4.5/5 stars.
