The Sony WH-CH400 are good sounding on-ear headphones. These are wireless-only and can’t be used with an audio cable. They feel quite cheaply-made with very thin plastic and poor padding. They aren’t very comfortable and won’t create a good seal to block out ambient noise, meaning they won’t be great for commuting or to use at the office. On the upside, their battery life is long enough to last you a full workday without a problem, but they take a bit of time to fully charge. They also have amazing wireless range and support NFC for quicker and easier pairing.

The Sony WH-CH400 are flimsy on-ear headphones that aren’t very well-built. They are made out of thin plastic that feels cheap and that could easily break. On the upside, the cups are fairly dense and decently comfortable for on-ear headphones, but not everyone will like the fit. However, there’s minimal padding on the cups and none on the headband, which can get uncomfortable rather quickly for some. They have a nice and easy-to-use control scheme with physical buttons, but they won’t be the easiest to carry around as they don’t fold.


The WH-CH400 are flimsy looking on-ear headphones that can stand out by their bright mono-chromatic colors (red, blue, and grey) but also come in a more low-profile black design. The cups are very small with poor padding, and the headband of the headphones is thin but quite wide. The headphones rest on your ears without covering them. They look plasticky and feel like cheaply-made headphones.

6.5 Comfort
Weight : 0.23 lbs
Clamping Force
0.6 lbs

The Sony WH-CH400 aren’t very comfortable, like most on-ears we’ve tested so far. The padding on the ear cups seems fairly thick but the driver is hidden in it and in reality, there is barely any padding between your ears and the driver itself. The cups sit at an angle on your ears which may feel weird for some. The headband is made out of plastic and doesn’t have any padding on it, which isn’t comfortable during long listening sessions. On the upside, the headphones are very lightweight and aren’t too tight.

The CH400 have a pretty straightforward control scheme with common functionalities. You get a volume rocker that also serves as a track skipper, and the power button acts as a play/pause button on top of being used for call management as well. You can enter their pairing mode by holding the power button, but you’ll need to hold it for 7 seconds, which is quite long. You don’t have any voice prompts, but you can trigger your device’s voice assistant for voice-enabled commands.

6.9 Breathability
Avg.Temp.Difference : 4.2 C

Since the Sony WH-CH400 headphones don’t entirely cover your ears, they’ll be more breathable than most closed-back over-ears. They still trap a bit of heat under the ear cups, but this shouldn’t be an issue during casual listening sessions. You might sweat a bit more than usual if you work out with these, but it won’t be as drastic as some over-ear headphones.

Transmitter required : N/A

While the Sony WH-CH400 headphones have a smaller footprint than most over-ear headphones, they aren’t very portable due to the fact they can’t be folded in a more compact format and their cups don’t swivel, which would have made them easier to slide in a bag. The headband is quite flexible, but it might break if you try to squeeze them in a more portable format.

5.5 Build Quality

These headphones do not feel very durable and well-built. The whole build is made from thin plastic that feels cheap and easily breakable. On the upside, the cups are decently dense and the headband is flexible, but the plastic used is cheap and the one-piece design doesn’t help with durability, especially that you can’t fold them. Putting the headband under a bit of stress feels like it could snap easily.

6.5 Stability

The Sony WH-CH400 aren’t the most stable as they simply rest on your ears. They aren’t very tight, so a bit of head movement makes them sway around easily. They won’t be ideal for sports as they could easily fall off your head, but on the upside, since they are wireless, you don’t have any wires in your way that could get stuck on something and yank the headphones off your head. This shouldn’t be an issue during casual listening sessions and they could be used for a casual jog.

The Sony WH-CH400 are good sounding on-ear closed-back headphones. Their bass is accurate and punchy, their mid-range is well-balanced and even, while the treble is very good. However, their bass might feel light on thump and rumble and is very inconsistent across different users. Their treble is also lacking in detail on one driver and is slightly too sharp on the other. Overall, these headphones will be versatile enough for a wide variety of music genres.

8.6 Bass
Std. Err.
2.03 dB
Low-Frequency Extension
25.94 Hz
-1.92 dB
1.85 dB
0.01 dB

The WH-CH400 have great bass performance. Their LFE (low-frequency extension) is down to 26Hz, which is very good. However, their low-bass is slightly lacking, which results in a bass that may be a bit light on thump and rumble common to bass-heavy genres like EDM and dubstep. There’s also a small 2dB bump in mid-bass, responsible for the punch of bass guitars and kick of drums. Since the high-bass is accurate and follows our curve well, this will result in a fairly good bass, but it may feel a bit light on thump.

However, their bass delivery varies significantly across users, and is sensitive to the quality of fit, seal, and whether you wear glasses. The response here represents the average bass response and your experience may vary.

8.4 Mid
Std. Err.
2.07 dB
0.91 dB
1.37 dB
-1.85 dB

This mid range of the WH-CH400 is very good. The response throughout the range is fairly even and well-balanced, which results in an accurate reproduction of vocals and instrumentals. However, there’s a small bump around 500Hz, which could bring them forward in the mix. However, the effect is fairly subtle and will barely be noticeable.

8.2 Treble
Std. Err.
3.27 dB
0.21 dB
0.86 dB
-0.36 dB

The treble performance is also great. The response is flat and even throughout the response, with a small dip around 6kHz, which will have a negative effect on vocals, leads, and cymbals, but will be barely noticeable. There also seems to be a small mismatch in our unit drivers in the treble range, resulting in the right driver to sound a bit sharper.

5.5 Frequency Response Consistency
Avg. Std. Deviation
2.22 dB

The frequency response consistency of the Sony WH-CH400 is pretty bad in the bass range, but they perform quite consistently in the treble range between reseats. In the bass range, the graph shows major variations at 20Hz, reaching more than 20dB of difference between our human test subjects. This will be very noticeable and means that people’s listening experiences will differ greatly from one another.

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

These headphones have very good stereo imaging. Weighted group delay is at 0.35, which is good. The GD graph also shows that except for the area around 70Hz, which could sound a tad loose, the response is below the audibility threshold. This suggests a bass that is tight for the most part, and a treble that is transparent. In terms of driver matching, our test unit was very well-matched, which is important for accurate localization and placement of objects (voice, instruments, video game effects) in the stereo image, but there is a slight frequency mismatch between the L/R drivers. However, these results are only valid for our unit and yours may not perform the same way.

5.1 Soundstage
PRTF Accuracy (Std. Dev.)
3.75 dB
PRTF Size (Avg.)
1.68 dB
PRTF Distance
7.46 dB
Acoustic Space Excitation
Correlated Crosstalk
0.0 dB

The soundstage of the WH-CH400 is poor. These on-ear headphones PRTF graph shows a small amount of pinna interaction, with mediocre accuracy. This results in a soundstage that is perceived to be small and unnatural. There is also no deep notch around the 10kHz region and with their closed-back design, the soundstage will be perceived inside the listener’s head rather than in front.

6.4 Total Harmonic Distortion
Weighted THD @ 90
Weighted THD @ 100

The harmonic distortion performance of these headphones is okay. The level of THD throughout the range is fairly elevated, and the high peak around 5kHz will make these frequencies harsh and impure, which can get fatiguing after a while.



The WH-CH400 have a poor noise isolation performance. They only block noise passively, and unfortunately, the small on-ear cups don’t prevent noise from easily seeping into your audio. This means you may struggle to hear your music in loud environments, making them a bad option for traveling and commuting. They also leak quite a bit at higher volumes, so they may be slightly distracting to the people around you in quieter settings.

3.4 Noise Isolation
Isolation Audio
Overall Attenuation
-7.04 dB
0.75 dB
-6.57 dB
-16.01 dB
21.2 dB

The noise isolation performance of these headphones is bad. Their on-ear design doesn’t isolate against the deep rumble of a plane or bus engine, which means they won’t be suitable for commuting. In the mid-range, important for blocking out speech, they achieve about 7dB of isolation, which is fairly negligible. In the treble range, important for blocking out S and T sounds and A/C noise, they block out about 16dB of ambient noise, which is sub-par.

6.9 Leakage
Leakage Audio
Overall Leakage @ 1ft
40.54 dB

The Sony WH-CH400 have an acceptable leakage performance. The significant portion of their leakage is spread from 1kHz to 10kHz, which is a relatively broad range and will mostly consist of the high-mid and the whole treble ranges. The overall level of the leakage is not very loud either. With the music at 100dB SPL, the leakage at 1 foot away will average around 41dB SPL and peaks at 54dB SPL, which is about the same as the noise floor of most offices.



Detachable Boom

The WH-CH400 have an okay integrated microphone. In quiet environments, speech recorded or transmitted with this mic will sound noticeably thin, as well as muffled and lacking in detail. However, it'll still be relatively easy to understand in quiet environments. In noisy environments, the mic struggles to separate ambient noise from actual speech and won’t fare well in situations like a busy street or a subway station.

6.7 Recording Quality
Recorded Speech
236.29 Hz
FR Std. Dev.
2.84 dB
3368.2 Hz
Weighted THD
37.98 dB

The recording quality of the integrated microphone is passable. LFE (low-frequency extension) is at 236Hz, which means transmitted/recorded speech with this mic will sound slightly thin. The HFE (high-frequency extension) of 3.4kHz indicates speech that lacks detail and is noticeably muffled. This will have a negative effect on the intelligibility of speech, but it should still be understandable in quiet environments.

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

The integrated mic is mediocre at noise-handling. In our SpNR test, it achieved a speech-to-noise ratio of 15dB, indicating the mic is best suited for quiet environments and will struggle to separate speech from ambient noise in moderate and loud situations.


Active Features

The Sony WH-CH400 have a good battery life with over 16 hours of continuous playback, but they do take a bit of time to charge fully. They also only automatically turn off after 5 minutes after being disconnected from your source. Unfortunately, you can’t use these headphones passively as they don’t come with an audio cable, so you’ll need to recharge them if the battery is dead.

Passive Playback

The Sony WH-CH400 will allow you to listen to audio content for more than 16 continuous hours on a single charge, which should be more than enough for a normal workday. Unfortunately, they take more than 3 hours to charge fully, which is quite longer than most Bluetooth headphones. They will automatically turn off if they are disconnected from their source, but won’t do so if you’re still connected to your phone, for example. They also can't be used while charging, which is especially disappointing considering they can't be used passively with an audio cable either.

These wireless-only headphones are Bluetooth compatible and support NFC for easier pairing. However, the fact that they can’t be used wired over their USB charging cable is disappointing, since you can't use them with an audio cable either. They also have very high latency, so they won’t be suitable for watching video content and gaming. On the upside, they have an amazing wireless range and practically maxed out our testing facility.

10 Wireless Range
Obstructed Range

The Sony CH400 headphones have remarkable wireless range. They pretty much maxed out our testing facility in our line of sight range test and had an amazing 70ft of range when the source was obstructed by walls. You should be able to walk around an office or a small apartment with these headphones without them cutting off completely. However, wireless range is dependent on your device’s signal strength and many other factors, so your results may differ.

0 Latency
Default Latency
292 ms
aptX Latency
aptX(LL) Latency

Their latency is very high. Even if some apps and devices offer some sort of delay compensation, they won’t be ideal for watching video content and playing games. Most people should see a noticeable delay between audio and video content.

Compared to other Headphones

The Sony WH-CH400 are okay on-ear headphones that set themselves apart by their good audio reproduction. Unfortunately, their build quality is quite cheap and they feel quite fragile. See our suggestions for the best on-ear headphones and the best on-ear wireless headphones.

JBL T450BT Wireless

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.

Sony WH-CH500 Wireless

The Sony WH-CH400 are slightly better headphones than the Sony WH-CH500 Wireless. While the CH500 model feels better made, there’s a big difference in sound quality that favors the CH400. They also have better wireless range, but they don’t have the same great 20-hour battery life as the CH500. They also offer better value overall since they are cheaper.

Skullcandy Grind Wireless

The Skullcandy Grind Wireless are more comfortable on-ear headphones that can also be used wired. They’ll be more versatile than the Sony WH-CH400 and they are noticeably more durable too. These headphones will sound fairly similar, but the Grind will have a more accurate bass for most, with a slight V-shaped sound profile. They also take about half the time to charge, which is nice. However, the Grind don’t support NFC like the CH400 do, but you can use them wired, and also get an in-line microphone, which the Sonys are lacking.

Mpow H5 Wireless

The Mpow H5 Wireless are better headphones than the Sony WH-CH400. These over-ears offer great value thanks to their ANC feature. They are more comfortable than the Sony on-ears and will also have a decent sound quality, on top of being noticeably better-built. Their design is more stable due to larger cups, and their latency is fairly low for Bluetooth headphones. On the other hand, the WH-CH400 support NFC for quicker and easier pairing, and they have better sound quality as well. However, you can’t use them wired like you can do with the Mpow H5, which may be a deal-breaker for some.


6.2 Mixed Usage
Passable for mixed usage. The Sony CH400 have a good audio reproduction that is versatile for a wide variety of music genres but their on-ear fit won’t be ideal for other use cases. They won’t block out enough ambient noise to be suitable for commuting and they’ll be too leaky for the office. They won’t be stable enough for sports, but they won’t trap as much heat as over-ears. Their latency is also too high for watching TV wirelessly and they won’t be suitable for gaming, on top of having a microphone that won’t be good enough for online games.
7.2 Critical Listening
Decent for critical listening. Their bass is accurate and punchy, their mid-range is well-balanced and even, and the treble is very good. However, their bass might feel light on thump and rumble and is very inconsistent across different users. Their treble is also lacking in detail on one driver and is slightly too sharp on the other. Overall, these headphones will be versatile enough for a wide variety of music genres.
6.0 Commute/Travel
Mediocre for commuting. They aren’t that portable since you can’t fold them, and most importantly they don’t block ambient noise. This means noise will easily seep into your audio and will negatively affect your listening experience. They also won’t be the most comfortable option for long rides and flights.
6.7 Sports/Fitness
Passable for sports. The Sony CH400 aren’t the most stable headphones for most sports, but they’ll be fine for a casual jog. However, they don’t fold into a more compact format and they aren’t that easy to carry around. They won’t trap as much heat inside the ears as some over-ear headphones, but they still won’t be the most breathable option. On the upside, they are wireless, so you won’t have a cable in your way if you work out with these.
6.3 Office
Passable for the office. The Sony CH400 won’t isolate much ambient noise like ambient chatter and A/C systems, but you’ll have enough battery life to go through a normal workday without a problem. However, they aren’t the most comfortable on-ear headphones we’ve tested so far and you might feel discomfort quite quickly due to the poor cup and headband padding. On the upside, their range is pretty impressive, and you’ll be able to walk around the office without hearing too many audio cuts.
5.0 TV
Poor for watching TV. They won’t be comfortable for a long movie or binge-watching TV shows and their latency is too high to watch video content. You’ll see a noticeable delay between the audio and video content, which quickly gets frustrating, especially since you can’t use them wired without any latency issues. They also won’t be a good option if you’re looking for headphones that will block out household noise.
4.6 Gaming
Bad for gaming. These won’t be suitable for playing video games as their latency is very high and their microphone won’t rival a gaming headset's boom microphone. They also aren’t customizable and won’t be comfortable for long gaming sessions. These headphones should not be used for this use.
