The Sony WI-C310 are decent mixed-usage in-ear headphones. They are very lightweight, their neckband design is flexible and portable, and they’ll be stable enough for running. They have a decent sound profile but might be better-suited for bass-heavy genres. The bud cables are very long, creating big loops when wearing the headphones, which may be a bit cumbersome. On the upside, they have a good 17-hour battery life and isolate well against work environment noises, but won’t be the ideal choice for public transit. They are decent all-around headphones and offer good value, but don’t necessarily stand out from other similar in-ears.

Our Verdict

7.1 Mixed Usage

Decent for mixed usage. The Sony WI-C310 have a passable sound profile that will be better-suited for bass-heavy genres. Their fit isolates a bit of ambient noise and should be okay for blocking out the ambient chatter in your work environment, but won’t fare well in public transit. On the other hand, they are a good option for sports thanks to their portable and breathable design. These headphones have about 17 hours of battery life, meaning they’ll be great to use at the office during a full work day. Unfortunately, their Bluetooth latency could be too high for some when watching video content or gaming.

7.3 Neutral Sound

Decent for neutral listening. While they have a decent audio profile, the WI-C310 in-ear fit might not be optimal for neutral listeners. Their bass is quite powerful and a bit boomy while vocals and lead instruments can feel a bit nudged to the back of mix. Their treble is good but a bit uneven in very high frequencies. Unfortunately, they don’t have a dedicated companion app with an EQ to customize their sound to your liking.

See our Neutral Sound recommendations
7.5 Commute/Travel

Decent for commuting. The Sony WIC310 are very portable, can easily rest around your neck, and have a long battery life for the longest trips or rides. They have a decent isolation performance, but they don’t do well against deep engine rumbles. On the upside, you might be able to mask more ambient noise by raising your volume since they don’t leak too much.

See our Commute/Travel recommendations
8.0 Sports/Fitness

Good for sports. These headphones are very portable and easy to carry around to the gym. Their bud design is very small and doesn’t trap heat inside your ear, which is great since you won’t sweat more than usual wearing them. They are also stable enough for working out, but since the cables are very long, they create big loops and it’s easy to pull the headphones out of your ears.

See our Sports/Fitness recommendations
6.8 Office

Decent for the office. The small buds are fairly comfortable to wear for a while, but the in-ear fit might not be for everyone. Their isolation performance against work environment noises such as ambient chatter and A/C systems is very good. Also, they have a long 17-hour battery life, so they should last you for a couple of work days before needing charging. However, they don’t automatically turn off, so if you get up from your desk and leave them there, be sure to turn them off.

See our Office recommendations
5.4 Wireless Gaming

Poor for gaming. The latency of the headphones won’t be suitable for video games and their in-line microphone recording quality won’t be comparable to that of gaming headset boom microphones. Also, they can’t be customized and don’t have a feature-packed app like some headsets do.

Test Results

Style

The Sony WI-C310 are fairly simple around-the-neck headphones with a soft and flexible neckband design. The cables are flat and fairly long, which creates a big loop when putting them in your ears. They have a rubberized cover, the buds are very small, and they don’t protrude much out of your ears. They come in different colors such as white, black, blue, and gold. If you don't mind about the color of your headphones, take a look at the near-identical WI-C200.

The WI-C310 are fairly comfortable for in-ears. They don't go too deeply in your ear canal and don’t apply pressure inside your ear since the buds are very small. The headphones feel lightweight, but some may be annoyed by their long cables that can be bothersome. They come with three tip sizes to help you find the most comfortable fit. However, the in-ear fit might not be the most comfortable to wear for a while.

The WI-C310 have a pretty straightforward in-line remote with a 3-button scheme. You can play/pause your music, and take calls with the center button and double-tap it to trigger your device’s voice assistant. You also have volume controls, and holding them will either skip tracks or go to the previous one. You have audio cues when skipping tracks and when reaching maximum and minimum volume. You also get a clear voice prompt during the pairing procedure. Unfortunately, the buttons are a bit mushy, which makes tactile feedback a bit underwhelming.

Like most in-ear headphones, the WI-C310 are very breathable and won’t trap much heat inside your ears. This means you shouldn’t feel a big difference in temperature and won’t sweat more when working out with these.

Thanks to the flexible neckband design, the WI-C310 can easily be folded into a more compact format and will fit in most pockets or a bag. They are quite easy to carry around your neck as well. These headphones don’t take much space but, unfortunately, don’t come with a case to protect them when you’re on the move.

Build Quality

The Sony WI-C310 don’t feel like very durable headphones. The two modules feel like they’re made from thin plastic and are fairly fragile. While the cables are rubberized and flat, they feel thin and look like they could easily be pulled from the bud housing or the modules. On the upside, the buds are magnetic, which helps with cable management when they’re dangling around your neck.

7.0
Design
Stability

The Sony WIC310 are stable enough for a light run or workout. However, a very small tug on the cable is enough to make the buds fall out of your ears. While their wireless design means you don’t have a wire in the way, the earbud cables are still very long, creating big loops when wearing them, so be careful not to get them hooked on something.

The bass performance of the Sony WI-C310 is great. Their LFE (low-frequency extension) is down to 10Hz, which is excellent. There’s a small 1.5dB underemphasis in the low-bass range, which means they may lack a bit of thump and rumble common to bass-heavy genres, but this will barely be audible. The response then gets overemphasized in the high-bass, by about 2.5dB, which adds a bit of boominess and muddiness to the sound. If you prefer a more bass-heavy sound, check out the very similar Sony WI-XB400.

The mid-range response of the WI-C310 is also great. The vocals and lead instruments will be accurately reproduced. However, the small dip in mid-mid will slightly nudge them to the back of the mix, but this shouldn’t be too audible for most.

The Sony WI-C310 have very good treble performance. The response until 7kHz is well-balanced and even, but there’s a dip around 8kHz, followed by a sharp bump at 10kHz. This means that some frequencies will lack detail and brightness, while some other sibilants (S and Ts) will sound overly sharp and piercing. However, not everybody hears the treble frequencies the same way, so your experience may vary.

The stereo imaging is excellent. Their weighted group delay is at 0.14, which is very low. The group delay graph also shows that the entire response is well below the audibility threshold. This ensures a tight bass and a transparent treble reproduction. Also, the L/R drivers of our test unit were well-matched in frequency, amplitude, and phase response. This is important for the accurate placement and localization of objects (voices, instruments, video game effects) in the stereo image. Note that these results are only valid for our unit and yours may perform differently.

The soundstage 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 2 2019, Google Pixel Buds, or the Bose SoundSport Free.

The Sony WIC310 have a mediocre noise isolation performance. Their fit doesn’t block much lower frequencies like the rumbling of a bus engine, which means they won’t be ideal for commuting with an isolation performance of only 3dB. On the upside, they isolate by about 17dB in the mid-range, responsible for blocking out ambient chatter. In the treble range, responsible for sharp S and Ts and A/C fan noise, they achieved isolation of 42dB, which is excellent.

The leakage performance is great. The Sony WIC310 don't leak in the bass and mid ranges, which results in a thin-sounding leakage. The significant portion of their leakage is between 2kHz and 6kHz, which is a relatively narrow range. However, the overall level of the leakage is quiet. With the music at 100dB SPL, the leakage at 1 foot away averages at about 29dB and peaks at 46dB SPL, which is above the noise floor of an average office.

The in-line mic has a sub-par recording quality. The LFE of 523Hz results in a recorded or transmitted speech that is very thin. The HFE of 3.5kHz suggests a speech that lacks detail and presence. However, the intelligibility of speech on this microphone will still be understandable in quiet environments.

The in-line microphone of the WI-C310 is okay at noise handling. In our SpNR test, it achieved a speech-to-noise ratio of about 17dB, indicating it is best-suited for quiet and moderate environments. However, the mic will struggle to separate speech from ambient noise in loud situations.

However, they can take a bit of time to charge with just under three hours. Unfortunately, they don’t have any power saving features, so be sure to turn them off when you’re not using them.

These headphones are Bluetooth 5.0 compatible, so you might even get better results than what we’ve measured if your source supports it as well. However, they can’t be connected to multiple devices simultaneously and don’t support NFC, which is quite rare for Sony headphones.

With 215 ms of latency, the Sony WI-C310 might not be the best option to watch video content as some will notice a delay between audio and video. However, some apps and devices offer some sort of compensation, so you might not notice it as much.

Compared to other headphones

Comparison picture

The Sony WI-C310 are pretty basic around-the-neck headphones that don’t particularly stand out from the competition. They perform decently in the majority of our tests, without excelling at anything. Unfortunately, they don’t feel like premium headphones and the materials used feel a bit cheap. See our recommendations for the best headphones, the best earbuds, and the best neckband headphones.

Sony WI-XB400 EXTRA BASS Wireless
SEE PRICE
B&H

The Sony WI-C310 Wireless are a bit better than the Sony WI-XB400 EXTRA BASS Wireless in mixed usage. They perform similarly in most aspects, but the C310 have a more neutral sound, since they don't have the extra emphasis in the bass. Also, the C310 have better noise isolation, especially in the treble range, but the quality of the microphone is significantly worse.

Sony WI-C200 Wireless
SEE PRICE
B&H

The Sony WI-C310 Wireless and Sony WI-C200 are pretty much the same headphones. The main difference between the two models is that the WI-C310 have flat cables, while the WI-C200 have thin cables. The C310 are available in more colors and have slightly better isolation performance.

Sony WI-C400 Wireless

B&H

The Sony WI-C310 are better neckband headphones than the Sony WI-C400 Wireless. Their flexible neckband is easy to fold into a more compact format that will fit in most pockets. Their sound profile is significantly better and they take less time to charge. On the other hand, the C400 have NFC pairing and a Bluetooth sync button, but the WI-C310 are Bluetooth 5.0 and have noticeably better wireless range.

JBL Live 200BT Wireless

The Sony WI-C310 and the JBL Live 200BT Wireless are two similar performing headphones. The main difference between the two would be that the Sonys have a flexible band while the JBLs have a solid plastic band that can’t be folded and won’t fit in pockets. However, the Sony offer more battery life than the Live 200BT and are Bluetooth 5.0. On the other hand, the Sonys can’t connect to two devices simultaneously like the JBL Live 200BT can.

Jabra Elite 45e Wireless
SEE PRICE
Newegg.com

The Sony WI-C310 are better headphones than the Jabra Elite 45e Wireless, mainly because of their better audio quality. The Jabra have a very detail-lacking sound and an overemphasized bass, making them sound dark. On the other hand, the Elite 45e have a more comfortable earbud design, are noticeably better built, and come with stability fins that are great for physical activity. The Elite 45e also have a companion app with an EQ, which the Sonys are lacking. If you can EQ the Elite 45e to a sound you like, then they are the better choice.
