The Fitbit Flyer are good sports headphones that are also decent for most use cases. They have a fairly straightforward wireless design that feels well-built and durable. They're also stable enough for running, and come with a variety of tips and stability accessories to help you find a good fit. Unfortunately, they have a slightly overpowering bass and they lack a good app for added customization options.

The Fitbit Flyer have a typical wireless design that looks somewhat like the Jaybird X3 but feels a bit more premium. They're decently durable and stable sports headphones with a common in-ear fit but also include two sets of stability accessories for a secure fit when running and working out. They have a simple and efficient control scheme, and they're very breathable headphones since they do not cover your ears. They're also portable and compact enough to carry on your person at all times. However, if you're not a big fan of in-ears then they won't be ideal for you and their buttons can feel a bit mushy, but at least they have good auditory feedback.


The Fitbit Flyer have a simple and straightforward design that looks good and feels high-end. They feel a lot more premium than the Plantronics BackBeat Fit but do not benefit from the extra stability of an ear-hook design. They look somewhat like the Jaybird X3 but with slightly bigger earbuds, and fortunately, they do not stick out of your ears like the Bose SoundSport Wireless. They come in two color schemes, Nightfall Blue and Lunar Gray. The latter is a bit more flashy but still looks great for outdoor use. The special stability wings make them stand out from the other similarly designed wireless in-ears, but overall they do not feel very different from those models, especially when using the normal stability fins.

7.0 Comfort
Weight : 0.05 lbs
Clamping Force
0 lbs

The Fitbit Flyer have a typical in-ear fit that's decently comfortable but won't be for everyone. They come with 3 sets of gel tips of varying sizes and a couple of different stability wings and fins. The fit isn't altered much by the additional stability accessories though, so if you're not a big fan of in-ear designs you will have some of the same issues with these headphones.

7.2 Controls
OS Compatibility
Ease of use : Good
Feedback : Okay
Call/Music Control : Yes
Volume Control : Yes
Microphone Control : No
Channel Mixing
Noise Canceling Control : N/A
Additional Buttons : Bass Effect

These headphones have a decent control scheme that's easy to use but not as responsive. They provide call/music, track skipping, and volume controls. The buttons are well spaced out and intuitive but feel a bit mushy. On the upside, they give you a lot of auditory feedback and you can even change the language or switch to just tones. They also have a special EQ mode called power boost that you can enable by pressing the volume up and down buttons at the same time.

8.9 Breathability
Avg.Temp.Difference : 1.1 C

The Fitbit Flyer are very breathable headphones. They do not cover the ears so they won't make you sweat more than usual. The stability wings cause a slightly higher temperature difference since they have more points of contact with the notch of your ear than the fins but it's a very noticeable difference and shouldn't change much to your work out routine.

8.6 Portability
L : 2.1 "
W : 1.3 "
H : 2.2 "
Volume : 6 Cu. Inches
Transmitter required : N/A

Like most wireless in-ears, these headphones are very portable. They're compact and will easily fit into your pockets or bags. The carrying pouch also doesn't add much bulk, so they won't be much of a hassle to have on you at all times.

6.0 Case
Type : Pouch
L : N/A
W : N/A
H : N/A
Volume : N/A

The Fitbit Flyer come with a carrying pouch that will protect the headphones from scratches and minor water exposure. It's also fairly easy to carry on you at all times and will store all the accessories that come in the box. The pouch is very similar to the Jaybird X3 but its a bit easier to open without all the accessories tumbling out.

7.5 Build Quality

The Fitbit Flyer have a good build quality that feels decently high-end. The cable is flat and rubberized and feels durable enough to last you a while. The earbuds and the in-line remote also look well-made with a polished design and dense plastic that won't get damaged if you accidentally drop the headphones once or twice. They're also sweat proof and which makes them decently durable headphones, however, since the earbuds are not detachable if the cable snaps or the remote breaks you will have to get a new pair.

8.0 Stability

The Fitbit Flyer are stable sports headphones. They come with both stability fins and a wing design that some may prefer. In our test, the fins were a bit more stable than the wings but as long as you can get a secure fit they will be stable enough for exercising and working out.

Their bass is well-extended, consistent, and deep, but it is uneven and quite overpowering to the point of negatively affecting its punchiness. Their mid-range however, is very well-balanced but ever so slightly recessed on vocals and lead instruments. The treble range is about average and lacks some detail and sharpness on vocals, lead instruments and cymbals. Additionally, and like most other in-ears, they don't have a large and out-of-head soundstage. It should be noted that these headphones were measured with the Power Boost option enabled.

Sound Profile
6.6 Peaks/Dips
2.25 db
1.91 db
8.9 Frequency Response Consistency
Avg. Std. Deviation
0.23 dB

The frequency response consistency of the Fitbit Flyer is excellent. If the user is able to achieve a proper fit and an air-tight seal using the assortment of tips that come with the headphones, then they should be able to get consistent bass and treble delivery every time they use the headphones.

7.4 Imaging
Weighted Group Delay
Weighted Amplitude Mismatch
Weighted Frequency Mismatch
Weighted Phase Mismatch

The imaging performance of the Flyer is about average. The weighted group delay is 1.37, which is quite high, and among the worst we have measured so far. The GD graph shows that the problem area is in the lower bass, especially around 40Hz, which corresponds to the 40Hz dip in the frequency response. This suggests that the bass of the Flyer won't be very fast and tight, which will negatively affect its punchiness. On the plus side, the L/R drivers of our test unit were decently matched, which helps with the accurate placement and localization of objects (voice, instruments, footsteps) in the stereo image. The phase mismatch in the treble range although audible, won't have a significant negative effect on localization.

0.6 Soundstage
PRTF Accuracy (Std. Dev.)
PRTF Size (Avg.)
PRTF Distance
Acoustic Space Excitation

The soundstage of the Fitbit Flyer, like most other in-ears, is poor. This is because creating an out-of-head and speaker-like soundstage is largely dependent on activating the resonances of the pinna (outer ear). The design of in-ears and earbuds is in such a way that fully bypasses the pinna and doesn't interact with it. Also, because these headphones have a closed-back enclosure, their soundstage won't be perceived to be as open as that of open-back earbuds like the Apple AirPods or the Bose SoundSport Free.

7.2 Weighted Harmonic Distortion
WHD @ 90
WHD @ 100


The Fitibit Flyer block a decent amount of noise and barely leak. The in-ear fit creates a good seal that prevents a lot of high-frequency noise from seeping into your audio. However, since they are not active noise canceling they have a much tougher time isolating you from the low-frequency rumbles of an engine but should be good enough for commuting. Luckily since they barely leak even at high volumes you can mask some of the ambient noise by just playing your music at higher levels. 

7.0 Noise Isolation
Isolation Audio
Overall Attenuation
-19.76 dB
-4.29 dB
-19.65 dB
-36.83 dB

The isolation performance of the Flyer is decent. In the bass range, where the rumble of airplane and bus engines sit, they achieve 4dB of isolation, which is inadequate. In the mid-range, important for blocking out speech, they reduce outside noise by almost 20dB, which is great. They also have a a very good performance in the treble range, which is important for cutting out sharp sounds such as S and Ts.

9.8 Leakage
Leakage Audio
Overall Leakage @ 1ft
22.03 dB

The leakage performance of the Flyer is excellent. These in-ears do not leak in the bass and mid ranges at all, and the entirety of the leakage is in the treble range. The overall level of the leakage is also extremely low, making the leakage of these headphones practically non-existent.



Detachable Boom

The in-line microphone of the Fitbit Fliyer is mediocre. In quiet environments, speech recorded/transmitted with it would sound relatively full, but noticeably muffled and lacking in detail, which could make speech a tad difficult to understand at times. In noisy environments, they will struggle to separate speech from ambient noise in even in moderately loud situations like a busy street.

6.2 Recording Quality
Recorded Speech
226.27 Hz
FR Std. Dev.
4.03 dB
2560.0 Hz
Weighted THD
23.42 dB

The recording quality of the Fitbit Flyer's mic is about average. The LFE (low-frequency extension) of 226Hz, is decent, indicating that speech recorded or transmitted with it would sound relatively full. The HFE (high-frequency extension) of 2.6KHz however, is mediocre and results in a speech that lacks detail and presence. This would have a small but noticeable negative effect on the intelligibility of speech.

6.3 Noise Handling
Speech + Pink Noise :
Speech + Subway Noise :
15.31 dB

Below-average noise handling. In our SpNR test, the in-line microphone of the Fitbit Flyer achieved a speech-to-noise ratio of 15dB, suggesting their microphone is best suited for quiet environments, and may struggle to separate speech from background noise in moderate and loud situations.


Active Features

The Fitbit Flyer have a mediocre battery life of 6.5 hours but are not compatible with the Fitbit app for more customization options. They also benefit from a quick charge feature that will give 1 hour of playback from a 15-minute charge. Unfortunately, they do not have a lot of power saving features and remain connected to your device which drains the battery.

These headphones have a mediocre-at-best battery performance. They lasted about 6.5 hours of continuous playtime at moderate volume, which should be okay for most listeners as long as you remember to turn them off. Unfortunately, they do not have an auto-off timer when inactive (unless you disconnect your Bluetooth source) and you can't use them while they are charging. On the upside, a quick 15-minute charge gives you an hours worth of playback.

They are not compatible with the Fitibit app as they have no sensors or trackers, and the app does not offer customization options like an equalizer.



The Fitbit Flyer are wireless Bluetooth in-ears that have simultaneous multi-device pairing but no NFC support. They are fairly easy to pair with Bluetooth devices and have a good wireless range. However, like most Bluetooth headphones with no low-latency codecs, they won't be ideal for watching a lot of video content due to the relatively high latency.

These headphones have multi-device pairing but no NFC support. On the upside, their hold-to-pair procedure is fairly easy to use and pairs easily with most Bluetooth devices.

These headphones have quite a bit of latency at 220ms. This makes them poorly suited for watching videos and gaming and is a bit on the higher side for Bluetooth headphones.

Compared to other Headphones

The Fitbit Flyer are good sports headphones that have a fairly common wireless in-ear design. They're decently premium-looking headphones and feel durable enough to last you a while. They also come with a variety of tips and stability accessories that make them stand out when compared to competing models. However, they have a fairly weak battery performance with no power saving features, and they do not have a very customizable sound unlike some of the models below. 

Bose SoundSport Wireless

The Bose SoundSport Wireless are slightly better headphones than the Fitbit Flyer. The Bose have a more comfortable earbud fit that most will prefer over the in-ear fit of the Fitbit Flyer. They also have a better-balanced sound quality and a better battery performance overall, thanks to their auto-off feature. The Fitbit Flyer, on the other hand, have a more isolating in-ear fit that's more suitable for noisy environments. They also leak a lot less so you can play your music at higher volumes without distracting the people around you. On the upside, both headphones are stable enough for sports and most physical activities.

Jaybird X3 Wireless

The Jaybird X3 are better wireless in-ears than the Fitbit Flyer. The X3 have a better isolating in-ear fit and come with a couple more tip options than the Flyers. They also have a better default sound that you can customize via the Jaybird app and a longer battery life. On the other hand, the Fitbit Flyer have a more premium look and feel, and come with a few more stability fin options, which may be more comfortable for some ears. They also have a much easier to charge design that does not require a proprietary charging clip like the Jaybird X3, which can be very limiting.

Apple AirPods 1 Truly Wireless 2017

If you prefer the compact format of a truly wireless design, then the Apple AirPods will be a better choice. However, if you want a typical wireless in-ear for sports, go for the Fitbit Flyer instead. The Apple AirPods have an excellent 25-hour battery life, thanks to their compact and portable charging case. They also have an earbud design that most will find more comfortable than the FitBit Flyer. On the other hand, the Flyers have a more isolating in-ear fit, which makes them more suitable for noisy environments and commutes. They're also more stable thanks to their multiple tips and stability fins sizes, and they have a lot more bass and will sound more exciting than the AirPods.

Bose SoundSport Free Truly Wireless

If you prefer the compact format of a truly wireless design, then the Bose SoundSport Free will be a better choice; however, if you want a typical wireless in-ear for sports go for the Fitbit Flyer instead. The Bose have a better sound quality than the Fitbit Flyer. They're also a bit more comfortable to wear thanks to their earbud design. The Bose are also a bit more portable, thanks to their truly wireless design, although their case is rather bulky. On the other hand, the Flyers have a more isolating in-ear fit, which makes them more suitable for noisy environments and commutes. They're also more stable thanks to their multiple tips and stability fins sizes. They also have a longer battery life on a single charge.

Sony WI-SP600N Wireless

The Sony WI-SP600N have about the same performance as the Fitbit Flyer, but they're more customizable. The Sony have a better companion app, which gives them a lot more options and features you can tweak to better your listening experience. They're also noise cancelling so they do a bit better for commuting. On the other hand, the Fitbit Flyer are a bit more stable for the gym with a smaller and easier to use in-line remote. They also have a longer battery life and offer slightly better value for your money if you do not mind not having an EQ.

6.8 Mixed Usage

Decent for mixed usage. The Fitbit flyer are best used for sports, but they're portable and isolate enough for more casual uses like commuting and traveling. They also barely leak, so they're a good option for noise sensitive environments like being at the office. However, they have quite a bit of latency which will not be suitable for watching movies or gaming.

6.3 Neutral Listening

Average for neutral listening. They have a lot of bass which unfortunately sounds a bit boomy and overpowers some of the instruments and vocals in the mid-range. Their treble range is also somewhat recessed but has a few spikes that makes sharp sounds a bit piercing, especially, on already bright tracks. They won't be the best headphones for more neutral listeners and have a small soundstage due to their in-ear closed back design. However they should sound good enough for most.

7.3 Commute/Travel

Above-average for commuting. They isolate decently well against ambient noise, they're portable and have an easy-to-use control scheme. They should be suitable for most commuters but would be better if they had a longer battery life with better power saving features.

7.9 Sports/Fitness

The Fitbit Flyer are good sports headphones. They have a breathable in-ear fit, with multiple stability fins and wings that make them stable enough for working out and running. They're also wireless, they have a simple and efficient control scheme, and they're compact enough to fit into most pockets which make them easy to have on you at all times.

6.7 Office

Average for office use. They block a decent amount of noise and barely leak, so you will rarely distract your colleagues even if you like to listen to your music at higher volumes.

4.9 Wireless Gaming

Below-average for gaming. They have an average-at-best microphone, but way too much latency to be suitable for gaming. They're also not as customizable as most gaming headsets since they have no app support
