The JBL T450BT are average mixed-usage on-ears, with a decent sound. They are lightweight and stable enough for running and they have an easy-to-use control scheme and a somewhat portable design. Unfortunately, their build quality is flimsy and not as durable as some of the other on-ears we've tested, like the Skullcandy Grind. They do not have a headphone jack or wired mode, which might be a deal breaker for some listeners.
The JBL T450BT have a lightweight on-ear design that feels a bit cheap but looks decent enough for most. They have a somewhat similar design to the Sony MDR-ZX110NC but with a thicker, more durable headband and better hinges. They're also a bit more comfortable, although they are fairly tight on the head, which will not be ideal to wear for long listening sessions. On the upside, the tight fit does make them stable enough for jogging and exercising, even if they are not sports headphones. They also have a decent but cramped control scheme and no headphone jack, which may be a deal breaker for some, but it's not a big issue for most wireless headphone users.
The JBL T450BT have a simple and understated on-ear design that looks a bit cheap but feels better built than some similarly designed headphones. They look somewhat similar to the Sony MDR-ZX110NC and the AmazonBasics Lightweight On-Ear. They have small on-ear cups, a low profile headband that's not padded, and no headphone jack. They also come in a couple of color schemes to better suit your taste and preferences. They should look good enough for most but will feel a bit cheap overall, especially when compared to other on-ears in their price range like the Skullcandy Grind and JBL E45BT.
The JBL T450BT are lightweight on-ears that are slightly tight on the head. They're decently comfortable, but the lack of padding on the headband, the slightly cheap ear cup pads, and the somewhat tight fit, means they won't be the best headphones to wear for really long listening sessions. Also, the on-ear design might not be for everyone.
The JBL T450BT come with a decent control scheme. They provide a 3-button set up on the right ear cup for track-sipping, volume control, and call/music management. They also have a power button that enables the pairing mode if you press and hold when turning them on. Unfortunately, though the buttons are decently clicky they are hard to differentiate by feel alone. They're also cramped on the bottom of the ear cup which will cause a couple missed inputs occasionally.
These headphones are fairly breathable on-ears. They do not cover your ears entirely, like most over-ear designs, so they do not obstruct as much airflow. They will be breathable enough for sports.
The JBL T450BT are above-average portable on-ear headphones. They conveniently fold up into a much more compact format and can easily be carried around in a bag and will fit in some larger jacket pockets. They are more compact than the E55BT but they are not as small as some other on-ear models we've tested like the Koss PortaPro and will still feel a little cumbersome to carry around on your person.
The T450BT do not come with a case or pouch.
The build quality of the T450BT is mediocre-at-best. The all-plastic design looks a bit cheap and does not feel very durable. The headband might snap under moderate physical stress, but at least the plastic used in their build quality feels a little denser and sturdier than some of the other similarly designed headphones like the Sony MDR-ZX110NC or the AmazonBasics Lightweight On-Ear. The ear cups feel decently dense and overall the lightweight design should be able to handle a couple of accidental drops but will break a lot easier than other better-made on-ears we've reviewed at the around the same price like the Skullcandy Grind or Sound Intone CX 05.
The JBL T450BT are quite stable on the head. They're lightweight and tight enough that they do not move much during casual listening sessions. They also and have no cables that can get tangled up or hooked on to anything. They're even stable enough for running but will not be the ideal option for sports since the headband will occasionally shift when tilting your head far enough or lying down like when doing crunches or a bench press.
These headphones have no headphone jack and do not come with an audio cable. However, they do come with a micro USB charging cable.
The JBL T450BT is a decent sounding pair of closed-back over-ear headphones. They have a deep, powerful, and punchy bass, a clear and flawless mid-range, and a decently-balanced treble. However, their bass is a bit heavy and boomy, and prone to inconsistencies with certain types of glasses, and their treble lacks a bit of detail and may sound too sharp on S and T sounds. Overall, they are a decent choice for most musical genres, including vocal-centric and especially bass-heavy ones.
The bass is quite good. LFE (low-frequency extension) is at 10Hz, which is excellent. Also, low-bass, which is responsible for the thump and rumble common to bass-heavy tracks is within 0.2dB of our neutral target. However, mid-bass, responsible for the body of bass guitars and the punch of kick drums, and high-bass, responsible for warm, are overemphasized by more than 4dB. This makes the bass of the JBL a little bit heavy and muddy.
The mid-range is excellent. The response throughout the range is virtually flat and very even. This results in a clear and well-balanced reproduction of the fundamental and lower harmonics of vocals and lead instruments.
The treble range of the T450BT is decent. The response throughout the range is decently balanced and even, which is good. However, the 5dB dip around 5KHz negatively affects the detail and articulation of vocals and lead instruments. Also, the peak around 10KHz, overemphasizes the sibilances, which could make the S and T sound a bit piercing on certain tracks. This will be mostly noticeable on vocals and cymbals.
The frequency response consistency is decent. Their delivery in the bass range is quite consistent and within 3dB across most people. However, it is possible that wearing glasses could break the seal between the headphones and your ears and cause up to 6dB of drop in the bass range, which is will be noticeable. On the other hand, they have a very consistent treble delivery across multiple re-seats, which is good.
The JBL T450BT have great imaging. Their weighted group delay is 0.3, which is quite good. The graph also shows that the entire group delay is below our audibility threshold. This ensures a tight bass and a transparent treble reproduction. Additionally, the L/R 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 games effects) in the stereo image.
The soundstage of the T450BT is sub-par. Due to their on-ear design, the JBL don't interact with the pinna and don't activate its resonances. That's why the PRTF response is basically a flat line. This, and their closed-back design, results in a soundstage that is perceived as small and located inside the listener's head.
The JBL T450BT have an average harmonic distortion performance. The amount of THD produce in the bass and mid ranges is a bit elevated, but on the plus side, there is not a big rise in THD at 100dB SPL, compared to 90dB SPL.
The JBL T450BT do not isolate well in noisy conditions. They are not noise-canceling headphones and have fairly small on-ear cups that do block a lot of ambient noise so you will hear what is going on in your environment even when playing music. This means they won't be the best option for commute and travel but on the upside, since they do not leak much you can play your music at higher volumes to mask some of the noise that will seep into the ear cups.
The JBL T450BT have a sub-par noise isolation. These on-ear headphones, don't have ANC (active noise cancellation) and therefore do not provide any isolation in the bass range. This means that they won't block the low rumbling sound of an airplane or bus engine. In the mid-range, important for blocking out speech, they provide about 8dB of isolation, which is average. In the treble range, occupied by sharp sounds like S and Ts, they reduce outside noise by more than 24dB, which is decent.
The leakage performance is very good. The significant portion of the leakage is spread across the mid and treble ranges, which is a relatively broad range. However, the overall level of the leakage is quite low. With the music at 100dB SPL, the leakage at 1 foot away averages at 36dB SPL and peaks at 43dB SPL, which is noticeably below the noise floor of an average office.
The JBL T450BT have a mediocre-at-best microphone. In quiet environments, speech recorded or transmitted with this mic will sound relatively thin, noticeably muffled, and lacking in detail. In noisy situations, it will struggle to separate speech from ambient noise, even in moderately loud environments, like a busy street.
The recording quality of the T450BT's integrated mic is mediocre-at-best. The LFE (low-frequency extension) of 339Hz indicates a recorded/transmitted speech that sounds thin. The HFE (high-frequency extension) of 3.3KHz results in a speech that's noticeably muffled and lacking in detail. Also, the response between the LFE and HFE points of this microphone wasn't very even or flat with our test signal, which suggests a relatively unnatural sound.
The microphone of the JBL T450BT is mediocre at noise handling. It achieved a speech-to-noise ratio of 12dB in our SpNR test, meaning they are best suited for quiet environments and may struggle to fully separate speech from ambient noise even in moderately loud places.
The JBL T45BT have a decent 12-hour battery life but no power saving features and no passive playback so once they are out of battery, you cannot use the headphones. They also do not come with an app. They should have enough battery life to last you a full workday of heavy use, but their lack of an auto-off timer means they will continue to drain when paired to your phone even when inactive. They also have no app support so you can't customize their sound quality, which is a little disappointing but somewhat expected, since most budget JBL headsets do not support the JBL headphones app.
These headphones have about 12.5 hours of battery life and will last you a full workday of heavy and casual use. Unfortunately, they take fairly long to charge at 2.8 hours and they do not have any power saving features or passive playback so they won't be the best option for a long trip without access to a power source. They also do not continue to play while charging. For slightly more continuous playing time, take a look at the Sony WH-CH400, or if you want headphones that can be used passively too, look at the Sony WH-XB700.
These headphones do not support the JBL Headphones app.
The JBL T450BT are Bluetooth only headphones with no wired option. They have a decent wireless range and a lower than average latency performance for a Bluetooth headset. Unfortunately, they still have a bit too much latency to be the best option for watching movies or gaming, and since they do not come with an audio cable, you won't be able to reduce latency by using them wired or have mic and audio support by plugging them into your console controllers. They also do not support NFC or multi-device pairing.
These headphones do not support NFC or multi-device pairing. On the upside, their hold-to-pair procedure is fairly easy to use.
The JBL T450BT are Bluetooth only headphones with no headphone jack or audio cable.
The JBL T450BT do not have a base/dock. If you want a versatile headset with a base that you can also use wired check out the Arctis 7 by SteelSeries.
These headphones have a decent wireless range. They reached up to 31ft when we left the Bluetooth source in another room and had a line of sight range of about 95ft. It should be decent enough for most use cases especially if you keep your device on you but they will not be the best option to use with a fixed Bluetooth source like a PC or TV (see our recommendations for the best on-ear wireless headphones).
These headphones have better than average latency performance for most Bluetooth headphones. Unfortunately, they still have a bit too much delay at 140ms to be the best option for watching movies or playing video games on your phone.
The JBL T450BT are average mixed usage on-ears with a decent sound but a budget design. They look and feel a bit cheap due to their mostly plastic build quality that's not as good as some of the other on-ear headsets within their price range. They're also not the most comfortable headphones to wear for long listening sessions but on the upside, their tight fit makes them stable enough for some sports and they sound balanced enough to please most listeners. Unfortunately, they are a bit too bright on some tracks and since they have no headphone jack you can't use them passively when the battery dies or wired with your console controllers. See our recommendations for the best on-ear headphones, the best headphones for running and the best wireless headphones.
The JBL E45BT are better headphones than the JBL T450BT. The E45BT have a more premium-looking design that's more durable than the T450BT. They also sound better and have a headphone jack, so you can use them wired if their battery dies or with your console controllers. The E45 also have a better battery life and can pair with 2 devices simultaneously, unlike the more budget T450BT. On the other hand, the T450BT are a bit more lightweight, portable, and stable for sports than the E45BT.
If you prefer a compact on-ear design than the JBL T450BT could be a decent choice, however, the JBL E55BT are much better in most aspects but are bulkier over-ears. The E55BT are more premium and durable than the T450BT. They sound better, have a longer battery life, and can pair with two devices at once. They also have a headphone jack so you can use them wired when their battery dies or with your console's controller. The T450BT, on the other hand, are a bit more lightweight, portable, and stable for sports than the E55BT.
The JBL T450BT are better on-ear headphones than the Sony WH-CH500. They have a similar cheap feeling but they sound better and leak less, so you can raise the volume in loud commutes. They have more than half the latency of the Sonys and are more stable for sports, making them a bit more versatile. However, the Sony WH-CH500 have a slightly better microphone and a longer battery life. They also support NFC for quicker and easier pairing, and they have an amazing wireless range.
The JBL T450BT Wireless are better sounding headphones than the Sony WH-XB700 unless you’re looking for a thumpy, bass-heavy sound profile, in which case you should go with the Sonys. Both headphones are built quite similarly, but the WH-XB700 come with an audio cable for you to use the headphones passively, which you can’t do with the JBLs. You get a longer battery life with the Sonys, and their wireless range is noticeably better. They also have a companion app that allows a bit of customization and they support the aptX codec, but their latency is a bit higher than the T450BT’s.
The JBL T450BT Wireless are better mixed-usage headphones than the Sony WH-CH400, but the Sony have better sound quality. Other than that, the JBLs are more stable, better-built, leak less and have about half the latency of the CH400. On the other hand, the Sony headphones have more battery life, better wireless range, and they support NFC. If sound quality is your most important criteria, then the Sonys will be the better choice.
The Skullcandy Grind are much better on-ear headphones than the JBL T450BT. The Grind have a great build quality for their price, they're also a lot more comfortable than the T450BT. The Grind also have longer battery life, a slightly better-balanced sound quality, and a headphone jack so you can use them wired with most devices, unlike the JBLs. On the other hand, the JBLs have a more compact and portable design that folds and can even fit into some larger jacket pockets. They're also lighter and leak a little less at high volumes.
The JBL T450BT are slightly better headphones and offer a better value for your money when compared to the Koss Porta Pro Wireless. The Porta Pro Wireless have a more comfortable, portable, and breathable design than the JBLs. They also have a well-balanced and open sound that does not sound as sharp as the T450BT. They also have a slightly longer battery life, although not by much. On the other hand, the JBL T450BT have better noise isolation and leak a little less thanks to their closed design. They also have an easier to use control scheme and a slightly sturdier build quality, although not by much since they are mostly plastic.
Average for mixed usage. The JBL T450BT are Bluetooth-only headphones with a decently balanced sound and a lightweight on-ear design that's stable enough for running and working out. However, their build quality is very plasticky and looks a bit cheap. They do not block a lot of noise passively so they won't be the best option for commute and travel, and they do not have a headphone jack so you cannot use them passively when the battery dies or wired with your console controllers. This also means they won't be the best option for watching videos since there's no way to reduce latency.
Decent for critical listening. The JBL T450BT have decently well-balanced sound with a good bass and mid-range but a slightly over-emphasized treble that may sound a bit too sharp on already bright tracks. Unfortunately, they are not the most consistent headphones so on some users they will have less bass especially if you wear glasses. They also have a small soundstage due to their closed back, on-ear design which will not be ideal for more critical listeners.
Mediocre for commuting. They have a straightforward control scheme and a decent battery life. They're also decently portable and compact which makes them a bit easier to carry around on your person. Unfortunately, they do not isolate well in loud environments, which isn't ideal for commuting or traveling.
Above-average for sports. Their tight fit and wireless design mean they won't easily fall off your head even when running. The JBL T450BT also have a decent control scheme but won't be the ideal headphones for sports since they still move around a bit when on your head depending on the exercise. On the upside, they should be stable enough for running and jogging.
Average for office use. They do not isolate well in loud, noisy environments so they won't be the ideal choice for a lively office. On the upside, they do not leak too much so you can play your music a little louder than average without distracting the people around you.
Below average for home theater use. They have a bit less latency than typical Bluetooth headsets but it's still a bit too much for watching videos and movies. They're also Bluetooth-only headphones that do not come with an audio cable to reduce latency or to use wired with your tablet and home theater setup.
Below-average for gaming. They have a mediocre microphone, and slightly too much latency to be suitable for gaming. They have no customizable options and they're not as comfortable to wear for really long gaming sessions. They're also Bluetooth-only headphones that will not work with your consoles.
