Other carried over features from the X3 to the X4 that shouldnâ€™t go unnoticed are the ultra light remote and impressive battery life. The remote is light, useful and has a ton of controls that work with both iOS and Android, including summoning Siri and Google Assistant. Itâ€™s made easy by the super tactile buttons that are almost too satisfying to press.
The battery life is still the same eight-hour battery life the X line is known for and thatâ€™s more than enough. For someone who goes on light jogs throughout the week, the battery lasted me a week a half on a single charge.Â Also, a quick ten-minute charge will get you one hour of continuous playback in case youâ€™re in need of a quick top off.
Jaybird didnâ€™t improve any of the internal drivers and thatâ€™s fine because it didnâ€™t have to. The Jaybird X3 sounded absolutely fantastic and the X4 sound just as great. Jaybird says itâ€™s still the same driver set-up with the 6mm driver with cone-shape housing.
This provides a full sound that tends to emphasize the lower end a little more. On thumpy songs, you can really feel the bass, but itâ€™s not exaggerated like something youâ€™d find with Beats. The highs and mids also do a great job of instrument separation. On something like The Eaglesâ€™ â€œHotel California,â€ I really took away the acoustic guitar riffs.
The X4 sound great out of the box, though if you want to change it up to something with more bass, you can do so through the Jaybird MySound app. I kept the sound profile on the standard Flat sound since thatâ€™s what the earphones come with, but you have the option to adjust it if you feel compelled. Through the app you can adjust highs, mids and lows.
Though there are many other options on the market, if you want to get the best workoutÂ Bluetooth earphones, Jaybirdâ€™s X4 are it. From sound to functionality, the X4 check off every box. I didnâ€™t find myself wanting something that sounds better or had better battery life.
I would not recommend buying the X4 if you have the X3 unless waterproofing is a feature you desperately need. But if you are looking for your first pair of workout earbuds and are unsure about which ones you should buy, save yourself the hassle and go with the X4.
The Jaybird X4 retail for $129.99, which is in the same price range as most premium Bluetooth earphones go for, so youâ€™re not paying excess for a great pair of earphones that will be great companions the next time you go on an outdoor activity.
