The Anker SoundCore Spirit X are good sports headphones, versatile enough for most use cases. They have an above-average build quality that feels a lot more high-end than their price would suggest. They also have a decent sound with a lot bass, a comfortable and stable in-ear fit for the gym, and a better control scheme than the similarly designed Anker Soundbuds Curve. Unfortunately, like the Curve, they won't be the best choice for loud, noisy environments, watching movies or gaming.

Our Verdict

7.0 Mixed Usage

Decent for mixed usage. The Anker SoundCore Spirit X are versatile enough for most use cases, except home theater and gaming, since they are Bluetooth only headphones with fairly high latency. On the upside, they're a great option for sports thanks to their stable, compact and wireless ear-hook design. They also have a long 12hr battery life and a decent build quality, that feels a lot more premium than their price range. However, they do not feel as durable as some of the more expensive wireless in-ears we've tested since they have thin cables. Their sound quality also has a bit too much bass for more critical listeners but should be good enough for most listeners.

7.2 Neutral Sound

Decent for neutral listening. The Anker Spirit X have a slightly bass heavy sound that will overpower some instruments and vocals in the midrange, however, the rest of their audio reproduction is fairly well balanced. Their mid-range is relatively flat, so instruments will not sound too forward or recessed, although they will be a bit cluttered due to the emphasized bass range. They don't sound as sharp as some of the other in-ears we've tested and fans of bass will enjoy the added thump and rumble these headphones produce, especially while working out at the gym. Unfortunately, they have small closed earbuds that cannot create a bid spacious soundstage. This means they won't be the best headphones for more neutral listeners but should sound good enough for most, especially if you like a little bass.

See our Neutral Sound recommendations
7.1 Commute/Travel

Decent headphones for commuting or traveling. They have mediocre isolation that isn't very good at reducing the rumble of a bus/train/plane engine, but will reduce the chatter around you. They have a decent sound that is best suited for bass-heavy genres. They have excellent breathability, and there should be no issues wearing them for longer commutes.

See our Commute/Travel recommendations
8.0 Sports/Fitness

Good headphones for sports and fitness use. The Anker Spirit X have an ear-hook design that is great for sports. Even during intense movements, they shouldn't fall off, but the seal isn't perfect so the sound changes a bit as they move, which isn't great for jogging. They are comfortable for longer workouts, and they breathe well. They are very compact headphones that are easy to carry around, but they are a bit larger than true in-ear due to the ear-hooks. They produce a decent sound that is better suited for bass-heavy genres.

See our Sports/Fitness recommendations
6.6 Office

Decent headphones for office use. The Anker Spirit X have mediocre isolation but a very good leakage performance. You can listen to your music at higher volumes, without bothering your coworkers and they are a comfortable in-ear fit and a long battery life that will easily last a typical workday.

See our Office recommendations
5.5 Wireless Gaming

Sub-par headphones for gaming. The Anker Spirit X are comfortable and can be worn for long gaming sessions without getting too hot. They produce decent sound and the bass is a bit exaggerated which can be good for some games. They can only be used wireless, and they have too much latency. They have a mediocre in-line mic that works for gaming, but won't provide the best vocals. They cannot be used with any gaming consoles without a special adapter.

Style

The Anker Spirit X have a decent-looking, sporty aesthetic that looks and feels more premium than their price range would suggest. They have thick and flexible ear-hooks, and a more polished earbud design than the Anker Curve. They also have a better in-line remote. Unfortunately, like the Curve, they also have thin cables that do not seem as durable as some of the more expensive wireless sports headphones we've tested like the Fitbit flyer. This somewhat cheapens their design, and they also do not come in as many color schemes as most sport-oriented headphones. On the upside, their understated look will work for most.

The Anker Spirit X, like the Curve, are quite comfortable for in-ear headphones. The tips do not enter the ear canal as deeply as most in-ears, which makes them more comfortable and removes a bit of the soreness and pain some listeners experience during long listening sessions with in-ear headphones. Unfortunately, since they do not enter the ear canal as deeply, they tend to slide out of your ears sometimes and may need to be adjusted somewhat often, which may get a bit annoying. It's not a big issue, but it's more common when doing physical activity. Overall though, these headphones will be comfortable enough for most listeners.

The Anker SoundCore Spirit X have a slightly better control scheme than the Anker Curve. The buttons are more responsive with clicky feedback and they're better spaced out on the in-line remote. They also have a simple 3 button setup with no additional features. It's an easy-to-use and efficient control scheme that provides all the essential functions; call/music, track skipping, and volume controls.

Breathability
Avg.Temp.Difference 1.1 C

The Anker SoundCore Spirit X, like the Beats Powerbeats3 Wireless, the Altec Lansing True Evo and most in-ear headphones, are very breathable. They have an ear-hook design which does have more points of contact with your ear than typical in-ear models. However, the temperature difference is negligible and won't make you sweat more than you have to during more intense physical exercises since they do not cover your outer ear like over-ear and on-ear designs.

The Anker SoundCore Spirit X are easy to carry around on your person and come with a good compact case. Like most wireless in-ear headphones, they're portable, lightweight and you can fold them to fit into your pocket, bag, or purse. They're slightly larger than straightforward, wired in-ear designs (since they have ear-hooks), but they're still very portable and come with a decent case.

These headphones come with a decent hard case that will protect them from minor impacts, scratches, and falls. However, the case shell is not as hard as some of the other hard cases we've tested but on the upside, it's compact and can fit into a pocket.

Design
Build Quality

The Anker SoundBuds Spirit X have the same build quality as the Anker Curve. They have a slightly more polished earbud design and a better in-line remote but thin and non-replaceable cables. The earbuds and ear-hooks are fairly dense and relatively sturdy, making them better built than most sports-oriented headphones in their price range like the Senso ActivBuds S-250 or the Mee Audio X6 Plus. They're also more water resistant, but we have yet to implement a reliable and comparable test for water resistance without permanently damaging some headphones. For waterproof headphones with a thicker and shorter cable, take a look at the JBL Endurance Dive.

Design
Stability

Unlike the SoundCore Liberty Air, the Soundcore Spirit X have a stable ear-hook design that's great for sports. They also have a couple of stability fins included in the box that helps with the fit, which makes them even more stable. However, the earbuds do slip out of your ear canal from time to time especially during more intense activity. They won't fall from your ears but the change in the seal when they move around alters their sound, which is not ideal when running or working out.

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.

The bass is great. Their LFE (low-frequency extension) is at 10Hz, which is excellent. Low-bass, responsible for the thump and rumble in bass-heavy genres like EDM, Hip-hop and film scores, is overemphasized by more than 5dB. This results in quite a bit of thump and rumble, which fans of bass may like. Mid-bass is also hyped, but only by 3dB. High-bass, responsible for warmth is over our neutral target by less than 1dB, which is an improvement over the SoundBuds Curve. Overall, the bass is thumpy and heavy without sounding muddy and cluttered.

The Anker SoundCore Spirit X have an excellent mid-range performance. The overall response is quite even and flat but recessed by about 2dB. This nudges the vocals and lead instruments towards the back of the mix, by giving bass and treble a bit more emphasis.

The treble performance is good. Low-treble is even and within 0.65dB of our target. Mid-treble is also quite well-balanced, but a little uneven between 8Khz and 10KHz. This could make some of the sibilance (S and T sounds) slightly lacking, and some other sibilances a tad too sharp. Overall though, their treble response is quite well-balanced, which is important for a good reproduction of vocals, leads, and cymbals.

The imaging performance is excellent. The weighted group delay is at 0.17, which is very low. The GD graph also shows that the entire group delay response is below the audibility threshold. This ensures a tight bass and a transparent treble reproduction. Additionally, the L/R drivers of our test unit were very well-matched, which is important for the accurate placement and localization of objects (instruments, voice, footsteps), in the stereo image.

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.

The Anker SoundCore Spirit X have a mediocre isolation performance. In the bass range, where the rumble of bus and airplane engines sit, they achieve about 2dB of isolation, which is barely noticeable. In the mid-range, important for cutting out speech, they isolate by more than 14dB, which is above-average. In the treble range, occupied by sharp S and T sounds, they isolate by about 24dB, which is also above-average. If you want sports-oriented wireless headphones that provide a bit more isolation than the Spirit X then check out the Jaybird Freedom 2 or Jaybird Tarah.

Overall Leakage @ 1ft

The leakage performance of the Spirit X is great. Like most other closed-back in-ear, these headphones don't leak in the bass and mid-ranges. The significant portion of their leakage is in the treble range and between 4KHz and 7KHz, which is quite a narrow range. The overall level of the leakage is not loud either. With the music 100dB SPL the leakage at 1 foot away averages at 34dB SPL and peaks at around 60dB SPL, which is just above the noise floor of an average office.

The microphone has a mediocre recording quality. The LFE (low-frequency extension) of 285Hz means speech recorded/transmitted with it will sound noticeably thin. The HFE (high-frequency extension) of 3.1KHz is poor and results in speech that is muffled and lacking in detail. It also negatively affects the intelligibility of speech.

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

These headphones have an interesting feature. When you start playing music immediately after pairing, the music fades in instead of immediately going to full volume.

The Anker Spirit X have very high latency and are unsuitable for watching videos. The latency is slightly worse than the Anker Curve. They also do not support the aptX codec.

Compared to other headphones

Comparison picture

The Anker SoundCore Spirit X are decently versatile wireless sports headphones and one of the best cheap earbuds we've tested. They have a stable and sweatproof ear-hook design with additional stability fins.  They also have a long 12hr battery life and an above-average sound quality that packs a lot of bass. They're lightweight and portable and surprisingly well-designed for their budget price. They're one of the best wireless earbuds for running we've tested. Unfortunately, although they are stable, the earbuds tips do tend to slip out of your ear canals from time to time, which can be a bit annoying. They also have relatively thin cables that do not look as durable as the rest of the design, and they are not as customizable as some of the other headphones compared below. See our recommendations for the best wireless earbuds under $50 and the best cheap wireless earbuds.

Anker SoundBuds Curve Wireless
Unavailable
B&H

The Anker SoundBuds Curve and the Anker Soundcore Spirit X are practically the same headphones, with very slight differences. The Spirit X are slightly better due to their higher sweat and water resistance, and their in-line remote offers better tactile feedback. You also get a cinch for easier cable management. If you have a Bluetooth 5.0 source, you might get better wireless range and connection stability with the Spirit X. On the other hand, the Curve have lower latency, support the aptX codec, and are even more affordable. These two headphones are great budget options, but if you don’t really care for the additional sweat resistance, the Curve will satisfy most users.

Anker SoundBuds Curve Upgraded 2019
SEE PRICE
Newegg.com

The Anker SoundBuds Curve Upgraded 2019 Headphones are marginally better headphones than the Anker SoundCore Spirit X Wireless. They look and feel almost identical and have very similar sound profiles, but the Curve 2019 have a much longer battery life and their treble range is slightly more accurate.

Anker SoundBuds Sport Wireless
Unavailable
B&H

The Anker Soundcore Spirit X are better in-ears overall when compared to the Anker SoundBuds Sport. The Spirit X have better sound quality, a more stable and durable design for sports, and they're a lot more sweatproof than the Anker Sports. The Spirit X also have a better control scheme and a much longer battery life that lasts more than twice as long as the SoundBuds Sport. On the other hand, the Sports are a bit more portable and have a better noise-isolating in-ear fit, so they're more suitable for noisy environments and commuting.

Beats Powerbeats3 Wireless
SEE PRICE
B&H

For the money, the Anker Soundcore Spirit X might be a better choice for most consumers. The Beats Powerbeats3 Wireless are better headphones than the Anker Spirit X since they have a slightly more neutral sound signature and feel more solid due to thicker cables. On the other hand, the Ankers are more comfortable and come with a nice solid case. Unfortunately, they don’t have the great wireless range of the Powerbeats3, but if you keep your phone on you during your workouts, this shouldn’t be an issue.

Anker SoundCore Liberty Air Truly Wireless
SEE PRICE
B&H

The Anker SoundCore Liberty Air are more versatile than the Anker Soundcore Spirit X. The truly wireless design of the Liberty Air gets rid of the cable and has a more portable design. Fans of bass may prefer the sound profile of the Spirit X, but the Liberty Air has better overall sound quality. The fit of the Liberty Air is also better for isolating ambient noise than the Spirit X. However, the Spirit X have a longer battery life, and their ear-hook design is very stable for sports. You also get a nice in-line remote with volume controls and are rated IPX7, while the Liberty Air is rated IPX5 for sweat and water resistance.

Jaybird X2 Wireless
SEE PRICE
Newegg.com

The Jaybird X2 are a better sports headphone and headset overall than the Anker Soundcore Spirit X. The X2 have a more isolating in-ear fit that's better for noisy environments and commuting. They also have a slightly more portable design since they do not have ear-hooks like the Ankers. The Ankers, on the other hand, are a bit more stable thanks to those ear hooks. They also have a longer battery life and a more comfortable in-ear fit than the Jaybird X2.

Jaybird Tarah Pro Wireless
SEE PRICE
B&H

The Jaybird Tarah Pro are better headphones than the Anker Soundcore Spirit X. They are better-made and you can also customize their sound to your liking thanks to their companion app. Their amazing wireless range is also better, and you get better default sound quality, even before EQ’ing them. On the other hand, the Spirit X are very comfortable in-ears and come with plenty of fit options. They also come with a nice hard case and have good sound quality for their price point, which might offer better value for most users.

JBL Endurance Dive Wireless
SEE PRICE
B&H

The Anker SoundCore Spirit X Wireless are slightly better sports headphones than the JBL Endurance Dive and offer better value thanks to their affordable price. They are more comfortable and their physical controls are easier to use than the touch-sensitive area of the Dive. They fit nicely inside the ears and are very stable for sports. Their sound quality is also a bit more accurate, and they have almost double the amount of battery life of the Endurance Dive. On the other hand, the JBL’s fit isolates against a good amount of ambient noise, which makes them a better option for commuting. Their cable is also thicker and rubberized, which makes them more durable than the Spirit X. They also have a noticeably better wireless range and have onboard storage for when you want to use them for swimming or working out without a phone.
