The Jaybird X4 Wireless are excellent wireless sports in-ears that can also be used casually. They block a fair amount of noise and just leak a little. They’re sturdy enough for most sports and small enough to carry in your pocket. With the MySound app, you can tailor your sound to your taste, and they have good battery life. They are somewhat similar to the X3, with the X3 marginally outperforming it in terms of tone, but they have a similar design.
The Jaybird X4 resembles the Jaybird X3 in appearance. The in-line remote is identical, but the honeycomb pattern on the earbud tips and the stability fins are missing. They have a sporty appearance, but far fewer color options than the X3, which was still less vibrant than the previous X2.

Compared to the X3 and Anker SoundCore Liberty Air, the X4 is more comfortable. The new earbud-like tips don’t go as far into your ear canal as the Freedom 2 and Skullcandy Jib, and they’re a little more secure than most in-ears. Unfortunately, like most in-ears, they aren’t easy for everybody and can become tiring after long periods of listening. On the plus side, they come with two conform foam tips, which most people prefer.
The X4’s in-line remote is almost identical to the X3. The buttons are readily available, and the feedback is positive. You get a basic play/pause button that also answers/ends calls, as well as a volume control with track skipping. Since the in-line remote is rated IPX7, it could be more sweatproof and waterproof than the X3, which is a welcome addition given rumours that the X3 remote stopped charging after a few uses. The remote is also marginally superior to the Tarah, which does not feel as clicky but has the same basic 3-button configuration.
Since the Jaybird X4 are wireless in-ear headphones, they are highly portable. They can comfortably fit into most pockets and bags, enabling you to carry them with you at all times. They also have a small pouch that doesn’t add too much weight.
Like the X3, the X4 comes with a small pouch. It will shield the headphones from minor water damage and scratches. Unfortunately, it lacks the small solid case found on the X2, but it does make them more compact.
The build quality is similar to that of the X3. The cable is flat, and the headphones seem to be sturdy enough to withstand a few drops. They’re also IPX7-rated, but we don’t have a way to measure that in our current test bench. Unfortunately, the cord control clips have been replaced by a cinch, which some people seem to dislike.
The Jaybird X4 are lightweight headphones that can be used for a variety of activities. You’ll have no trouble running and practising with them. They have four tip options, two of which are comply foam tips and three of which are stability fins, so you can find the most comfortable and stable fit. Since they’re wireless, they’re less likely to get tangled up in something and pull the earbuds out of your ears. Despite the fact that the stability fins appear to be slightly different, they are exactly the same.
The output in isolation is about average. They reached almost 6dB of isolation in the bass range, where the rumble of aeroplane and bus engines can be heard, which is mediocre. They minimise outside noise by more than 19dB in the mid-range, which is very good for blocking out speech. They isolate around 38dB in the treble range, which is occupied by sharp S and T sounds and machine fan noise. The X4 performs worse in the bass and treble ranges than the original Jaybird X3, owing to its more earbud-like nature. The Jabra Elite Active 45e are sports headphones that allow you to run while remaining conscious of your surroundings.
With a 1.7-hour charging time, the Jaybird X4 has a battery life of around 7 hours, which is a little longer than normal for most wireless in-ears models. They don’t have an auto-off feature, so be sure to turn them off if you’re not going to use them again until later in the day. If you intend to use them for your entire work shift, the battery life will be insufficient, but most casual listeners would find it sufficient. Furthermore, the proprietary charging dongle is restrictive, and you must keep it with you at all times to charge your headphones. You should also look into the Tarah Pro, which has a much longer 13-hour battery life and removes the need to bring the cradle around with you.
The Jaybird X4 will connect to two devices at once, which is ideal if you regularly move between your phone and machine. Their pairing process is also fairly simple, requiring just a few seconds of holding the play button on the in-line remote.
They have a higher latency than the X3, which is noticeable when watching videos or playing games. 211 milliseconds is longer than most Bluetooth headphones. The X2 has lower latency than both of these models.
Pros and Cons
The Jaybird X4 are a great pair of sports headphones. You can find the most secure and safe match for your activities by experimenting with various tips and stability fins. The in-line remote hasn’t changed much since the X3 model, and it still has a clear control scheme. You won’t have to worry about a wire getting in the way of your workout because it’s wireless. And in their carrying pouch, they are small enough to fit in your pockets.
For mixed-use, this is above average. The Jaybird X4 are sports headphones that can also be used on a daily basis. They have a great sound quality and are more relaxed than the previous X3. Unfortunately, they are in-ear headphones, which might not be appropriate for all. They block a good deal of ambient noise but only leak a little. They are also wireless, so you won’t have to worry about a wire getting in the way every day. Because of its long battery life, they can last you most of the day.
