The JBL Free X are decent truly wireless in-ears. They are virtually identical to the JBL Free in nearly every respect. They have a compact earbud design that should be comfortable for most but may not fit everyone equally well. They have a decent, well-balanced sound and are suitable for most music genres. They also have great isolation and do a decent job at blocking out noise. Unfortunately, like many truly wireless earbuds, their battery is mediocre, and they have a disappointing integrated microphone. They also have worse latency than most Bluetooth headphones, which won't be great for watching video content and gaming.
Decent for most use cases. They have a balanced sound for critical listening, a stable yet comfortable fit for sports, isolate noise fairly well for commuting, wonโt leak too much sound at the office, and are overall comfortable and portable truly wireless in-ears. On the downside, however, they don't have volume controls, which isn't very practical. They also have very high latency, which makes them less-than-ideal for watching TV or movies and have an inadequate microphone for multi-player gaming.
Decent for neutral listening. The JBL Free X have great bass, a well-balanced mid-range, and excellent treble. They sound relatively neutral and well-balanced overall. However, their high-mid and low-treble ranges are a bit recessed, which may make some instruments and vocals sound slightly distant. In addition, since they're closed-back in-ears, they donโt have the same soundstage as open-back, over-ear headphones for neutral listening. That said, their audio reproduction is quite good, and they sound balanced enough to please most listeners.
Decent for commute and travel. The JBL Free X have very good isolation and do a decent job at blocking out most noises. They donโt isolate as well as headphones with active noise cancelling in the bass range, but their performance will likely be acceptable for most, especially those who can get a good seal. Theyโre very portable and have a simple, easy-to-use control scheme, but lack volume controls, which means youโll have to pull out your phone whenever you want to adjust the volume.
Great for sports. The JBL Free X have a stable yet comfortable in-ear fit. They're lightweight and portable with an easy-to-use control scheme. Unfortunately, they have no volume controls and their unique design is not as stable as other truly wireless headphones. They also donโt have an IP rating, so they may not be as sweatproof as other sports in-ears, like the Jabra Elite Active 65t.
Decent for office use. The JBL Free X isolate speech quite well, which makes them suitable to use in a lively office. They also have excellent leakage performance, so you shouldnโt bother your colleagues if you raise your listening volume a bit. Although their battery does not last very long continuously, if you take short breaks to charge them in their case, they could last you all day. They donโt support multi-device pairing, though, so youโll have to manually switch between your work computer and your smartphone throughout the day.
Poor for gaming. The JBL Free X have a disappointing microphone and way too much latency to be suitable for gaming. They also do not have a companion app, which means they arenโt as customizable as most gaming headsets.
The JBL Free X are decent truly wireless in-ear headphones that are virtually identical to the JBL Free. What sets them apart from other truly wireless in-ears is their unique design, which is highly portable but may not fit everybody. If you like their truly wireless design but want something with a more stable fit or better battery life, check out our recommendations for the best truly wireless earbuds, the best wireless Bluetooth earbuds and in-ears, as well as the best wireless Bluetooth earbuds for running and working out.
The JBL FreeX Truly Wireless are overall better truly wireless in-ears than the Bose SoundSport Free Truly Wireless. The JBL have a less bulky design and a more portable charging case. They also isolate significantly more noise than the open-backed Bose, which makes the JBL a better choice for commuters or office workers. However, the Bose are better for critical listeners, since they sound better, are slightly more comfortable and have a longer battery life.
The JBL FreeX Truly Wireless are slightly better wireless in-ears than the Beats BeatsX Wireless. The JBL are more comfortable, well-built, and sound a bit better. However, the Beats have a much better battery since they’re not truly wireless, charge very quickly, pair more quickly with Apple devices, and isolate more noise. If you prefer the fit and durable design of the JBL, they’re a better choice, but the Beats are worth considering if you need the extra battery life and prefer a more stable fit.
The JBL FreeX Truly Wireless are better truly wireless in-ears than the Apple AirPods (1st generation) Truly Wireless in general. The JBL sound better, isolate more noise, have an easier-to-use physical control scheme, and have a more stable fit for sports. However, the Apple are much more comfortable than the JBL, have a significantly better battery, and are easier to use with Apple devices. The JBL are a better choice for most use cases, but if you’re a fan of the Apple ecosystem, the AirPods could be worth looking into.
The JBL FreeX Truly Wireless are better headphones than the EarFun Free Truly Wireless. The JBL are more comfortable, better-built, have a better-balanced sound profile, and their fit isolates better against ambient noise. On the other hand, the EarFun are Bluetooth 5.0 and have a USB-C port, but that's about it.
The JBL LIVE 300TWS Truly Wireless and the JBL FreeX Truly Wireless are both decent truly wireless in-ears that perform similarly. The biggest differences between the two are that the 300TWS have touch-sensitive controls that work better overall, a more stable fit thanks to their stability fins, and slightly longer battery life off a single charge. They also have access to a dedicated companion app that works great and adds quite a few customization options, while the FreeX don't have an app.
The JBL Free X Truly Wireless and the Samsung Gear IconX Truly Wireless are both decent truly wireless in-ears. They’re both well-designed and have similar isolation and microphone performance. The JBL sound slightly better out-of-the-box, but the Samsung can be customized via EQ presets in the Samsung Gear app. The Samsung also have a better battery, a more stable fit, and volume control. They’re both decent choices for most use cases, but the Samsung may be more advantageous for those who prefer more feature-packed headphones.
The JBL Free X have the same compact earbud design as the JBL Free. The earbuds are quite thick but relatively narrow. They feel fairly dense and durable, but less high-end than some of the more premium truly wireless models weโve tested, like the Sennheiser Momentum True Wireless. The JBL Free X have a more rugged look and donโt feel as polished as the Apple AirPods (1st generation) Truly Wireless. On the upside, they come with a good circular charging case that isnโt too bulky and even has a transparent cover so you can see if the earbuds are done charging without opening it.
The JBL Free X are comfortable in-ear headphones. Theyโre very lightweight and come with various tip sizes and earbud sleeves to help you find a good fit. Though the JBL Free X arenโt quite as comfortable as the earbud-style Bose SoundSport Free, the difference is negligible and theyโre more comfortable than other truly wireless in-ears like the Jabra Elite Sport. However, they have a unique shape that may not fit everyone, especially those with smaller ears.
The JBL Free X have two physical buttons on each earbud. Pressing the button on the right earbud will play or pause your music, answer calls, and trigger your deviceโs voice assistant. The button on the left earbud is for track switching: press once to skip to the next track or press twice to go back to last track. This very simple control scheme is easy-to-use and the buttons are good and clicky. Unfortunately, like the JBL Free, the Free X have no volume controls. Youโll have to reach for your audio device whenever you want to raise or lower the volume of what youโre listening to, which is a bit disappointing.
Like most truly wireless in-ears, the JBL Free X are very breathable headphones. This makes them a good option for working out since they wonโt make your ears sweat as much as over-ear headphones. The JBL Free X barely cause any changes in temperature, even after long periods of use. They do trap a little heat in the ear canal due to their in-ear design, especially if you add the rubber sleeves to the earbuds, but the difference is still fairly negligible and won't make you sweat more than usual.
The JBL Free X are very portable and will fit in almost any pocket. Their unique earbud design makes them a bit smaller than most truly wireless headphones, making them one of the most portable headphones we've tested. The case would also easily fit in larger pockets.
The JBL Free X have the same plastic hard charging case as the JBL Free. This case should protect the earbuds if you accidentally drop them, but it may open on impact, causing the earbuds to fall out and get damaged. The case is a bit bulky, but should fit a bit better in your pockets than some of the other truly wireless charging cases, like the Bose SoundSport Freeโs case.
The JBL Free X have the same good build quality as the JBL Free. The earbuds feel dense and durable enough to survive a few accidental drops and the case is sturdy. Although theyโre sturdy, they donโt look or feel as high-end as some of the other truly wireless headsets we've reviewed.
The JBL Free X are good earbuds for sports, thanks to their stable in-ear design. They come with multiple silicone tips and earbud sleeves to help you achieve a good, secure fit. Once in your ears, they don't move around much, but the unique shape of the earbuds may not fit as well for everyone, especially those with smaller ears. They should be good enough for running and working out for most people, but you may find yourself adjusting the fit of these earbuds a bit more often than other truly wireless in-ears. If youโre looking for headphones to wear mostly while running and working out, then you might want to consider models with ear-hooks instead, like the JBL Endurance Peak.
The JBL Free X have excellent frequency response consistency. Assuming the user can achieve a proper fit and an air-tight seal using the assortment of tips that come with the headphones, they should be able to get consistent bass and treble delivery every time they use the headphones. However, if the user cannot achieve a proper air-tight seal, they could experience a drop in bass.
The JBL Free X have outstanding bass. Low-Frequency Extension (LFE) is at 10Hz, which indicates deep and extended bass. Low-bass, responsible for thump and rumble, is slightly overemphasized by about 2dB, but otherwise, the response throughout the range is flat and well-balanced. This means the Free X have deep and punchy bass that isnโt overpowering. Itโs well-suited for all music genres, even though the lower frequencies are slightly emphasized.
The mid-range performance is excellent. The response in low-mid and high-mid follows our target curve well, but mid-mid is slightly underemphasized. The 2dB dip around 700Hz nudges the vocals and lead instruments towards the back of the mix, giving a bit of emphasis to the bass frequencies. Overall, the mid-range of the JBL Free X is quite well-balanced and produces clear and accurate vocals and instruments.
The JBL Free X have excellent treble. The response is relatively even throughout the entire range and is quite well-balanced. However, the wide and shallow dip around 5kHz will have a subtle but negative effect on the detail and presence of vocals and lead instruments. In addition, the dips and peaks between 6kHz and 10kHz will make sibilants, like S and T sounds, a bit uneven.
The imaging is excellent. The weighted group delay is at 0.16, which is very good. The group delay graph also shows that the group delay response never crosses the audibility threshold, suggesting tight bass and transparent treble reproduction. Additionally, the left and right drivers of our test unit were well-matched in amplitude, frequency, and phase response, which is important for the accurate placement and localization of objects (voices, instruments, video game effects) in the stereo image. However, these results are only valid for our unit, and yours may perform differently.
The JBL Free X have a bad soundstage. Creating a large and speaker-like soundstage is partially dependent on having a speaker-like pinna activation, and in-ear headphones bypass the pinna (the outer ear) and don't interact with it. Therefore, their soundstage will be perceived as small and located inside the listener's head. The JBL Free also have a closed-back design, which means that their soundstage won't feel as open as open-back earbuds like the Apple AirPods (1st generation) Truly Wireless.
The JBL Free X have decent noise isolation. They achieved about 10dB of isolation in the bass range, responsible for the rumble of airplane and bus engines, which is good for passive isolation. They isolate by about 21dB in the mid-range, important for blocking out speech, which is very good. They also do a good job at isolating sharp sounds like sibilants (S or T sounds), achieving about 35dB of reduction in the treble range. The JBL Free X didnโt isolate as well as the JBL Free in our tests, but this may be because the large earbuds can be difficult to fit in our dummy head and the scores obtained are within the tolerances of our testing.
The leakage performance is excellent. Most of the leakage is concentrated in a narrow band in the mid-treble range, from about 5KHz to 10KHz. This makes their leakage very thin and sharp sounding. The overall level of their leakage is also very low. With the music at 100dB SPL, the leakage averages around 24dB SPL, and peaks at around 37db SPL, which is far below the noise floor of the average office.
The JBL Free X have an integrated Bluetooth microphone with poor recording quality. LFE (low-frequency extension) is at 470Hz and HFE (high-frequency extension) is around 3KHz, which means that speech recorded or transmitted with this microphone will sound thin, lacking a bit of detail and noticeably muffled. However, it will still be relatively easy to comprehend, since speech intelligibility is mostly dependent on the 500Hz-4kHz range. If you want truly wireless earbuds with a better mic, then check out the Jabra Evolve 65t. They use a proprietary dongle to achieve better mic performance and are quite a bit more expensive than the JBL Free X , so they may not be worth it for everyone.
The JBL Free Xโs microphone has mediocre noise handling. In our SpNR test, this mic achieved a speech-to-noise ratio of approximately 13dB, indicating it is best suited for quiet environments and will struggle to separate speech from ambient noise in moderately loud or loud situations.
The JBL Free X have a mediocre battery. They provide 3.4 hours of continuous playback and their case provides 5 additional charges, which results in an estimated total of 20 hours of battery life if you place them in their charging case when not in use. Their battery should last you a full day of use if you take breaks to charge them, but they won't be ideal for long periods of continuous use. If you want a truly wireless design with a better battery, then consider the Apple AirPods (1st generation) Truly Wireless.
The JBL Free X do not support the JBL My Headphones app, like the JBL Everest Elite 700 do.
The JBL Free X connect to other devices via Bluetooth. They do not support NFC or multi-device pairing but they do auto-connect to the last paired device when you take them out of their charging case.
The JBL Free X have terrible latency and perform significantly worse than most Bluetooth headphones. With 336ms of latency, they are not suitable for watching movies or gaming.
The JBL Free X are truly wireless earbuds that donโt have an audio cable or a wired connection. If you want decent-sounding and stable in-ears with a wired connection, take a look at the TIN Audio T2 or the 1More Triple Driver In-Ear.
The JBL Free X have a charging case that delivers up to 17 hours of extra battery life. However, the case has no inputs and no distinguishing special features like Qi wireless charging on the Altec Lansing True Evo.
