The Sony SP600N are decent wireless in-ears for most use cases but a better choice for sports and working out. They have a good build quality, an easy-to-use and decently stable design, and they're portable enough to easily carry around on your person. They isolate sufficiently well in noisy conditions to be suitable for commuting, despite their comparatively weak active noise cancellation, and they do not leak much. Unfortunately, they have a relatively short battery life, and their sound quality is a bit too bass heavy which won't be ideal for every listener.
The Sony WI-SP600N have a decent wireless in-ear design that looks and feels high-end. They have thick and rubberized audio cables that feel durable. The earbuds are fairly dense, look well made and feel sturdy enough to handle a couple of accidental drops without getting damaged. They have a fairly typical in-ear fit, which won't be as comfortable for everyone, but on the upside, they do come with four tip sizes and two stability fins to help you find the right fit. The stability fins also make them somewhat stable for running, but the lack of good cable management and the slightly bulky in-line remote makes them a bit less stable for more intense workout routines. On the upside, the in-line remote is easy-to-use, well-built and provides good functionality.
The Sony WI-SP600N have a fairly typical wireless in-ear design that will work for most and looks fairly premium. They have a thick, rubberized audio cable and dense earbuds. The buds are slightly larger than average but not as bulky as the WI-SP500. Unfortunately, they also have a fairly big in-line remote, which may be a bit bothersome for certain listeners, but should be okay for most. On the upside, the remote looks and feels well-built and the SP600's design overall is decently high-end and durable. They also come in a couple of flashier color schemes like pink and yellow which some may prefer.
The Sony WI-SP600N have a common in-ear fit but come with four tip options, which makes them slightly more comfortable than average. They're lightweight and also come with stability fins so once you get the right fit for your ears they should be decently comfortable. However, the fairly large remote does pull a bit on the left earbud depending on the activity, and if you're not a big fan of in-ear designs, then you will get some of the same issues with these headphones. They will be comfortable enough for most but may not be the ideal headphones to wear for really long listening sessions. If you prefer a more earbud fit than typical in-ears, then check out the slightly lower-end model of the line up the WI-SP500.
These headphones have a good control scheme that's fairly easy-to-use and provides good functionality and feedback. They have a simple volume rocker, a multi-function music, and call management button, as well as an ANC button, on the side of the in-line remote, to enable/disable the noise cancellation feature as well as activate the ambient sound mode. They also have a seperate power button to turn the headphones on and initiate the pairing procedure. The controls all have decent feedback and are fairly easy-to-use once you get accustomed to the layout.
The Sony SP600N are very breathable headphones. Like most in-ear designs, they won't make you sweat more than usual during physical activity, and your ear will remain relatively cool throughout. The stability fins and in-ear fit does trap a small amount of heat within the notch of your ear, but it's a not a very noticeable difference and shouldn't change much to your workout routine.
Like most wireless in-ears, the WI-SP600N are very portable. They're compact and will easily fit into your pockets or bags. Unfortunately, they do not come with a carrying pouch or case, like most wireless in-ears at this price range, which is a little disappointing.
These headphones do not come with case or pouch.
The Sony WI-SP600N have a good build quality that feels decently high-end. The cable is thick, rubberized and feels durable. The earbuds and the in-line remote also feel 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 IPX4 water resistant which makes them a decent option for sports although they may not be as sweatproof as some of the other wireless in-ears we've reviewed like the Anker SoundCore Spirit X.
The WI-SP600N are stable enough for running and working out. They come with 2 sets of stability fins and have a fairly typical in-ear design that goes deeply into the ear canal so they won't fall easily out of your ears. The slightly larger than average in-line remote does tug a little on the left earbud and may cause it to slip out occasionally, but it does not happen that often especially if you get the right fit for your ears with the provided tip and stability fin options. They should be stable enough for most sports but won't be as stable as ear-hook designs for more intense workout routines.
They have a deep, powerful, and consistent bass, an even and well-balanced mid-range, but a lacking treble. Also, their bass is quite heavy and boomy, their mid-range is a bit recessed, and their treble is uneven and low on detail. This causes the vocals and lead instruments to be pushed a bit towards the back of the mix. Overall, these are a decent choice for fans of heavy bass, but won't be ideal for vocal-centric genres.
The Sony SP600N have excellent frequency response consistency. Assuming 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.
The imaging is great. The weighted group delay is at 0.18, which is very good. The GD graph also shows that the entire group delay response is below the audibility threshold, suggesting a tight bass reproduction and a transparent treble. 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 is poor. Since 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, their soundstage will be perceived to be small and located inside the listener's head. Their closed-back design also means that their soundstage won't feel as open as open-back earbuds like the AirPods and the SoundSport Free.
The Sony SP600N block enough noise to be a decent option for commute and travel in moderately noisy environments. They're also noise canceling headphones, but unfortunately, their noise canceling feature is not very strong. It cancels a bit of the low-frequency rumbling sounds of an engine on public transit, but it's not as good as other in-ears and earbuds with noise canceling, like the Bose QC20. On the upside, their in-ear fit does a good enough job passively and should be okay for moderately loud conditions. Also, since they barely leak you can play your music at higher volumes to mask the rest of the noise that might seep into your audio without bothering those around you.
The isolation performance of the SP600N is decent. In the bass range, where the rumble of airplane and bus engines sit, they achieve about 9dB of isolation with their ANC enabled, which is about average. In the mid-range, which is important for blocking out speech, they achieve a very good 21dB of isolation. In the treble range, where sharp and S and T sounds sit, they isolate by more than 32dB, which is also good. Unfortunately, their ANC system hurts the passive isolation of the headphones in the upper treble range, this is similar to what we observed with the WF-1000X and WF-SP700N, but won't be very noticeable.
The leakage performance is great. These headphones don't leak in the bass and mid-range, meaning their leakage will be quite thin sounding. The significant portion of their leakage is spread in a narrow band around 4KHz. The overall level of their leakage is quite low too. With the music at 100dB SPL, their leakage at 1 foot away averages at 31dB SPL and peaks at 55dB SPL, which is just above the noise floor of an average office.
The microphone of the Sony SP600N is mediocre-at-best. In quiet environments, speech recorded or transmitted with this mic will sound relatively thin, noticeably muffled, and lacking in detail. It may also be prone to pops and rumbling noises. 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 SP600N's microphone is sub-par. The bump around 90Hz makes these headphones prone to pops and rumbling noises, and the dip around 150Hz means speech recorded/transmitted with this mic may sound a little bit thin. The HFE (high-frequency extension) of 2.5KHz results a speech that is muffled and lacks detail.
The noise handling of the microphone is mediocre. In our SpNR test, it achieved a speech-to-noise ratio of 10dB. This means they are best suited for quiet environments, as it may struggle to fully separate speech from ambient noise even in moderately loud places.
The Sony SP600N have good customization options but a mediocre battery life of 5.6 hours. They support the Sony|Headphones connect app which gives you access to an EQ so you can customize their sound profile. The app also provides an in-app player and noise canceling options, but it's not as feature packed as when connected to the Sony WH-1000XM2. Unfortunately, their battery life is a little short and won't be ideal for heavy users. On the upside, you can squeeze a lot more battery life if you don't use the noise canceling feature.
The Sony SP600N headphones have a mediocre-at-best battery performance. They lasted about 5.6 hours of continuous playtime at moderate volume with ANC enabled. It 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, they charge fairly quickly at 1.4 hours and provide more than an hour's worth of playback from a quick 10-15 minutes charge.
The Sony WI-SP600N support the Sony | Headphones connect app which gives you a decent amount of customization options. You can EQ their sound with a graphic and preset equalizer. You can skip and rewind tracks directly within the app with the in-app player and you get some noise canceling options but they're not as in-depth as when paired to the WH-1000XM2. You also do not get room effects and multiple high-quality audio codecs but overall the app is well designed, feels useful and adds a level of customization that felt missing on the WI-SP500.
The Sony WI-SP600N are Bluetooth-only headphones with no audio cable or base/dock. They have a good wireless range and support NFC for easy pairing with mobile devices but cannot connect to multiple devices at once. They also have poor latency so they won't be suitable for watching videos or gaming.
The Sony WI-SP600N do not have multi-device pairing but do support NFC. Their hold-to-pair procedure is also not too difficult to use or not as frustrating as some Bluetooth headphones we've tested.
These headphones have quite a bit of latency at 174ms. This makes them poorly suited for watching videos and gaming and is a bit on the higher side for Bluetooth headphones.
These headphones have no wired option. If you want a good sounding wired in-ear, check the 1More Triple Driver In-Ear.
The WI-SP600N are decent mixed usage sports headphones. They have a good build quality and a compact design that's easy to carry around on your person. They're also stable enough for running and working out, although better cable management and a smaller in-line remote would have made them even more stable for sports. Unfortunately, they have a relatively short battery life that won't last as long as some of the models compared below. Their sound quality is also a bit too bass heavy but on the upside, you can customize their sound profile with their companion app which makes them a bit more versatile than the WI-SP500. See our recommendations for the best noise cancelling earbuds, the best wireless earbuds for iPhone and the best noise cancelling headphones under $100.
The Bose SoundSport Wireless are a slightly better wireless headset than the Sony WI-SP600N. The Bose have an earbud fit, which makes them a bit more comfortable for most listeners than the Sonys. They also have a longer battery life and a better-balanced sound that caters well to most music genres. They're also a tad more stable for the gym. The Sonys, on the other hand, have a better isolation performance which makes them a bit more suitable for other uses, like commute and travel. They also have a slightly more premium and durable design with better controls. You can also EQ the Sonys via their app, which you can't with the Bose.
The Sony WI-SP600N are a better wireless in-ear than the Sony WI-SP500. The SP600 have a more consistent sound and fit than the SP500 model, they also block more noise thanks to thief in-ear design and noise cancellation, so they're a bit more suitable for commuting and traveling as well as sports. Their fit a bit more stable thanks to the wing/stability fins, and overall they're easier to use with a more traditional inline remote. On the other hand, the SP500 have slightly longer battery life. They also have a unique earbud design that's a bit more comfortable when you get the right fit. They also have a unique look and feel that some may prefer over the SP600's design.
The Jaybird X3 are a better sports headphone than the Sony WI-SP600N. They're a bit more compact and easier to carry around since they come with a pouch. They also block a bit more noise passively with their in-ear fit than the active noise cancelling SP600N. They have a slightly better default sound, but north headphones can be EQed. On the other hand, the Sonys have a durable and premium looking design. They also noise canceling so they handle low-frequency noise a little better than the Jaybird, even if the Jaybirds' passive isolation is a bit better overall. The Sonys also have NFC, which makes pairing them with mobile phones a little easier.
If neutral sound is your most important criteria, then the AKG N200 Wireless are the better option against the Sony WI-SP600N. They also have better wireless range and noticeably lower latency. On the other hand, the Sonys are noise-canceling and will be a better choice for commuting if you need to block out ambient noise. They also have a companion app with a 5-band EQ to customize their sound to your liking.
The AUKEY Latitude are better headphones than the Sony WI-SP600N. They have better sound quality, wireless range, and can connect to two devices. Even if they don’t have an ANC feature like the Sonys, the AUKEY Latitude still have better isolation performance. On the other hand, they don’t have a compatible app with an EQ like the Sonys, which also have slightly better build quality but are more expensive.
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.
Decent for mixed usage. The Sony WI-SP6000N have a good build quality and easy to use controls. They also isolate well in noisy conditions despite having comparatively weak noise cancellation. They're also stable and portable enough for sports. Unfortunately, the slightly bulky in-line remote does reduce their stability. They also have a relatively short battery life when using the noise canceling feature. Their sound quality is also a bit too bass heavy but on the upside, they support the Sony | Headphones Connect app, unlike the SP500, so you can somewhat EQ their sound profile to better cater to what you're listening to.
Average for neutral listening. They pack a lot of bass, which some listeners may like, but unfortunately, it also tends to drown instruments and vocals in the mid-range. This gives them a boomy sound quality that is further emphasized by the slightly recessed mid and treble ranges. They won't sound as clear or detailed on most tracks, and they have a few peaks in the higher frequencies that will sound a bit sharp on some S and T sounds. On the upside, since they have a decent EQ with their app, you can somewhat tweak their sound profile to better match what you are listening to. Overall they should sound good enough for most users, but won't be the ideal option for more neutral listeners, due to their overly bass-heavy default audio reproduction and sub-par soundstage.
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. Also, the noise cancellation feature is not as strong but since they block a good amount of noise passively it shouldn't be much of an issue.
Good for sports. The SP600N have a stable and compact wireless in-ear design that you can easily carry around on your person and should be stable enough for running and working out. They also have a good control scheme that's easy to use but the lack of proper cable management and the slightly bulky in-line remote means they won't be as stable as some of the other sports headphones we've tested.
Average for office use. The Sony SP600N 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 than average volumes.
Below-average for gaming. They have a bit too much latency to be suitable for gaming. They're also not as customizable as most gaming headsets and are not compatible with most consoles via Bluetooth. They also have a mediocre-at-best mic for gaming.
