The xFyro xS2 are decent mixed usage truly wireless in-ears with a few flaws. They are decently comfortable, but the in-ear fit might not be for everyone. They’re very portable and have a good isolation performance, making them versatile for commute and everyday casual use. They also have a nice case that feels premium, but unfortunately, it doesn’t really protect the headphones and acts more as a power bank. Their sound quality is average-at-best and our unit had a frequency response mismatch. Additionally, you must connect the right earbud first or you’ll have inverted audio channels, which is frustrating. On the upside, they have great wireless range and are stable enough for running if you can find a good fit with the provided tip options.

Our Verdict

7.0 Mixed Usage

Decent mixed usage headphones. They won’t have a great audio reproduction necessary for critical listening, but their portable design and good isolation performance make them an above-average choice for commuting and to use at the office. They are also stable enough for light sports activities, and their in-ear design won’t trap heat. However, they have higher-than-average Bluetooth latency and will not be suitable for gaming and watching TV.

6.5 Neutral Sound

Average for neutral listening. These headphones have a mediocre sound quality with a lack of low bass and overemphasized high-bass and low-mid. Resulting in a boomy and cluttered mix, especially on vocals and lead instruments. Their treble range is also uneven, and some leads lack detail while some sibilances are overemphasized. Our unit also had a frequency response mismatch between the two drivers.

7.7 Commute/Travel

Above-average for commuting and traveling. They have good isolation performance, and they practically don’t leak so you’ll be able to raise your listening volume at high levels without bothering people surrounding you. They might be comfortable enough for short bus trips, but the in-ear fit might not be ideal for long flights.

See our Commute/Travel recommendations
7.8 Sports/Fitness

Good for sports. Their small and portable design makes them suitable for this use case. They are also truly wireless which gets rid of the risk to have a cable in your way or getting stuck on something. Like most in-ears, they are breathable and are stable enough for light physical activity. Those training in crowded gyms will appreciate their decent seal and isolation performance.

6.9 Office

Decent for the office. They isolate a good amount of noise and block ambient chatter well. They also barely leak so you’ll be able to enjoy your music at high volumes without disturbing surrounding colleagues. On the downside, the in-ear fit might not comfortable enough for a full work day and their short battery life will require you to charge them during the day.

5.0 Wireless Gaming

Bad for gaming. The xFyro xS2 have mediocre sound quality and have a sub-par microphone for online gaming. Also, their latency is too high to be suitable for gaming. They are also not compatible with consoles, and their battery life will be to short for long gaming sessions.

Style

The xFyro xS2 are truly wireless in-ears that have a low-profile look, but a slightly bulky earbud design. They protrude quite a bit out of the ear while wearing them. They have a decent finish and don’t feel too cheap. Their included aluminum case also has a nice style and high-end finish. These headphones come in three different color variants: black, blue and red.

The xS2 feel like typical in-ears, and the fit might not be as comfortable for everyone. They enter your ear canal deeply which could be bothersome for some, but come with three different ear tip options to help you find the most comfortable fit. They are very lightweight headphones, and you don’t feel them too much when plugged into your ears. However, their control scheme forces you to push the earbud even further in your ear to register an action, which is uncomfortable.

The control scheme of the xS2 is disappointing. While the buttons on both earbuds are clicky and offer good feedback, they aren’t easy to use. Every functionality needs you to push the earbud further inside your ear, which hurts. They also don’t have any volume control and only offer call/music management and track skipping (forward and backward).

Like most in-ears, the xFyro xS2 are very breathable since they don’t trap heat under an ear cup. You shouldn’t notice the difference in temperature and shouldn’t sweat more while using them during physical activity, which is nice.

Like most in-ears, these headphones are very portable due to their very small design. They can easily fit in a pocket or bag and are easy to keep on you at all times. They also come with a case, which adds slight bulk, but it will still fit in pockets.

The xFyro xS2 come with a decent solid case. However, the casing doesn’t really protect the headphones as the top of the buds is exposed. Also, only magnetic force is holding the headphones in place, meaning that quick motion or impacts will make the headphones fall out of their receptacle. On the upside, the case also acts as an 850mAh rechargeable power bank, in which you can plug a USB cable to charge other devices.

Design
Build Quality

The xFyro xS2 are decently-built headphones. The buds are made out of dense plastic and feel solid enough to survive a few impacts. The aluminum case is also very well-made and feels heavy and solid. They are also rated IP67 for great dust and water resistance. They can technically be submerged by water for 30 minutes at a depth of 3 feet but note that Bluetooth may not work as well underwater. They can be used in the shower or if it’s raining according to the manufacturer, but we do not have a test in our current test bench to measure this accurately.

Design
Stability

These headphones are fairly stable if you can find the right tip size for you. You’ll be able to jog with them or wear them at the gym, but they won’t be ideal for more intense physical activity. They are very lightweight, and their truly wireless design eliminates the risk of a cable getting stuck on something and yanking the headphones out of your ears. However, they do not have stability fins in order to help them to stay in place for more intense sports.

The frequency response consistency is excellent. If the user can 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.

Decent bass range performance. LFE is at 63Hz, which is below average. Low-bass, which is responsible for low-end thump and rumble, is lacking by about 3dB. While mid-bass is fairly close to our target curve, high-bass is overemphasized by over 5dB, making the bass sound muddy and boomy.

The xS2’s mid-range performance is good. The range is fairly even and flat, but there’s an 8dB tilt favoring lower frequencies, making vocals and lead instruments sound thick and cluttered.

The treble performance is decent. The range is slightly uneven, and most of it is underemphasized. This results in lead instruments lacking detail and brightness. Also, the mid-treble is a bit uneven and over our target curve by about 2dB, which emphasizes some sibilances while others will lack presence.

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 amplitude and phase response, but they were not in frequency response. This won't have a negative effect on the accurate placement and localization of objects (voices, instruments, video games effects) in the stereo image, but it will create unevenness and holes in the stereo field. These results are only valid for our unit, and yours may differ.

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, Google Pixel Buds, or the Bose SoundSport Free.

Their isolation performance is good (see our recommendations for the best noise cancelling earbuds). Despite lacking active noise cancelation, they passively isolate a good amount of ambient noise. They achieve about 13dB of isolation in the bass range, where engine rumbles sit, which is above-average. In the mid and treble ranges, they reduce the outside noise by 20dB and 41dB respectively, both values being very good.

The leakage performance is excellent. The xFyro xS2 basically do not leak, so there's no need to worry about disturbing people around with your music, even if you listen at very loud volumes. With the music at 100dB SPL, the leakage at 1 foot away averages at 21dB SPL and peaks at 33dB SPL, which is roughly as loud as a very calm room.

The xS2’s microphone has a sub-par recording quality. The LFE (low-frequency extension) of 273Hz means speech recorded or transmitted will sound noticeably thin. The HFE (high-frequency extension) of 2.4KHz is poor and results in speech that is muffled and lacking in detail. It also negatively affects the intelligibility of speech but will still be understandable in very quiet environments.

The integrated mic is sub-par at noise-handling. In our SpNR test, they achieved a speech-to-noise ratio of 10dB, indicating they are best suited for quiet environments and will struggle to separate speech from ambient noise in moderate and loud situations.

These headphones offer just above 3 hours of continuous playback on one charge. This is disappointing when compared to the 5 hours that were advertised by xFyro, especially since they take an hour and a half to charge fully. However, the case acts as a power bank for the headphones, and you can also charge other devices with it. You can expect a total of 30 hours of battery life according to the specs sheet. They also have a quick charge feature that gives you 75% of battery life in only 30 minutes of charging, but we can’t measure this accurately with our current test bench. Also, they go in a standby mode after being idle for a few minutes and can last up to 300 hours according to xFyro.

These headphones do not have multi-device pairing or NFC support. Their pairing procedure is also a bit complicated as you always need to power up the right earbud first, which connects to your device and then connect the left earbud to the right one. If you connect the left one first, channels will be inverted. However, you can connect each earbud to two different devices but can’t connect them as a pair to two devices.

Like most Bluetooth headphones without any lower latency codec, these headphones have too much latency to be used for watching video content or gaming. Also, they even have higher-than-average latency and what you will hear won’t match what you see on your screen.

Compared to other Headphones

The xFyro xS2 are decent mixed usage closed-back in-ears with a few flaws. While they are decently comfortable for in-ears and look good, these headphones are quite disappointing when compared to other headphones in a similar price range. Their sound quality is mediocre, and their battery life is short. On the upside, they have good isolation performance and amazing wireless range. See our recommendations for the best earbuds, the best earbuds with a mic, and the best wireless earbuds.

Apple AirPods 1 Truly Wireless 2017
SEE PRICE
Amazon.com

The XFYRO xS2 are more versatile headphones than the Apple AirPods. They have better isolation due to their closed-back design, which makes them a better choice for commuting and to use at the office. They also barely leak, have great wireless range, and aren’t exclusive to Apple products. On the other hand, the AirPods have significantly better build quality and have one of the best cases we’ve tested so far. They also have better battery life, but they lack a lot of bass.

Jabra Elite 65t Truly Wireless

The Jabra Elite 65t are better headphones than the XFYRO xS2. They are better-built and also have better audio reproduction, longer battery life, and also have a companion app with customization options. They also have a better control scheme and can connect to two devices simultaneously. On the other hand, the XFYRO xS2 have amazing wireless range and their case acts as a powerbank for other devices as well. They are also slightly more comfortable.

JBL Free Truly Wireless 2018

Amazon.com

The JBL Free are better headphones than the XFYRO xS2. They outperform the XFYRO in pretty much every category. They are more comfortable, are better built, and they have great audio reproduction. Both headphones have short battery life, but the XFYRO have better wireless range and you can also use their case to charge up other devices, which can be useful.

Altec Lansing True Evo Truly Wireless
SEE PRICE
Amazon.com

The XFYRO xS2 are better truly wireless headphones than the Altec Lansing True Evo. They are a bit more versatile thanks to their better isolation performance, which can be useful while commuting and at the office. They also have better wireless range and take less time to charge, for about the same battery life. On the other hand, the True Evo feel better-built, and some may prefer a design with stability fins for sports.

Jaybird Run Truly Wireless
SEE PRICE
Amazon.com

The Jaybird Run are better headphones than the XFYRO xS2. They have a more comfortable and better-built design. They also have a sound profile that follows our neutral target curve better and they also have a companion app that lets you EQ them to your preference. Their stability fins are also very useful for more intense sports and the headphones won’t come out of your ears. However, the XFYRO have better wireless range and better isolation performance, which make them a decent option for commuting.
