KZ ZSN PRO X vs Soundcore Anker P20i
Quick Verdict
The KZ ZSN PRO X is for wired listeners who want a budget hybrid dual-driver IEM with a detachable cable and passive isolation. It has no Bluetooth, no microphone, and no app. The Soundcore Anker P20i is for users who want true wireless convenience, punchy bass, long battery life, and app customization. Both score 78 overall, so the choice depends on wired versus wireless and whether you need call features. Buy the KZ for music, gaming, or monitoring with a 3.5mm source. Buy the P20i for daily wireless use, calls, and portable listening.

Sound Quality
Both models earn 24 out of 30 in sound quality, so on paper they are evenly matched in this category. The KZ ZSN PRO X uses a hybrid design with one dynamic driver and one balanced armature. This configuration typically lets the dynamic driver handle low frequencies while the balanced armature covers higher frequencies, but the listing does not specify the crossover details. The Soundcore Anker P20i relies on a single 10mm dynamic driver that the listing describes as oversized and emphasizes for punchy bass.
The KZ's balanced armature may offer a different character in the treble range, but the provided materials do not state exact frequency response curves. The P20i does not publish codec support, so it is unclear whether higher resolution Bluetooth audio is possible. The wired KZ avoids Bluetooth compression entirely, which can matter to listeners who prefer an analog signal. The P20i's 10mm driver is the only driver, so its sound will depend heavily on tuning and the app EQ.
Both score the same for sound quality, but they target different listening styles. The KZ is suited to users who want a hybrid driver arrangement and do not mind a wired connection. The P20i is suited to users who want a bass-forward wireless sound with the ability to adjust via EQ. Neither listing provides enough technical measurements to declare one clearly superior.
Comfort and Fit
The KZ ZSN PRO X scores 14 out of 20 for comfort and fit, while the Soundcore Anker P20i scores 15 out of 20. The KZ listing includes three pairs of earbud tips in small, medium, and large, which helps with seal and comfort. It also uses zinc alloy faceplates and resin cavities, which may add weight, but the listing does not publish the actual weight. The P20i listing does not publish weight or tip size options, so we cannot compare fit accessories directly.
The KZ is a wired in-ear monitor, so the cable runs over or around the ear depending on how the user wears it. The detachable 2-pin cable can be replaced if it fails, but no carrying case is included, so storage may be less convenient. The P20i is a true wireless earbud, meaning there is no cable to pull or tangle, which often improves daily comfort for casual use. Its compact charging case with lanyard adds portability, but the listing does not specify the earbud shape or included tip sizes.
The one-point difference suggests the P20i has a slight edge in comfort and fit, likely due to the freedom of a true wireless design. However, without published weights or tip options for the P20i, the comparison remains incomplete. Buyers who prioritize a secure seal with multiple tip sizes may prefer the KZ's included three sizes. Buyers who want no cable at all will likely lean toward the P20i.
Noise Control and Features
The KZ ZSN PRO X scores 10 out of 15 in this category, while the Soundcore Anker P20i scores 12 out of 15. The KZ offers passive noise isolation rated up to 26 dB with a proper seal, but it has no active noise cancelling. The P20i listing does not publish any noise cancelling specification, so we cannot confirm whether it has active noise control. This absence of information means the KZ's passive isolation figure is the only concrete noise-related spec.
Feature-wise, the P20i is clearly ahead. It has touch controls that can be customized through the soundcore app, 22 EQ presets, and Find My Earbuds. The P20i also includes AI call clarity with two microphones, which supports voice calls. The KZ on this variant has no inline microphone, no inline remote, and no companion app, so its feature set is limited to passive listening.
The P20i's app support and touch controls add convenience that the KZ cannot match. However, the KZ's passive isolation rating of up to 26 dB is a specific claim that may appeal to users who want to block external sound without batteries or electronics. The P20i's lack of a published noise cancelling spec is a notable gap for those who care about isolation. Overall, the P20i wins this category on features, but the noise control comparison is uneven because one model provides no noise spec.
Battery, Bluetooth and Connectivity
The scoring here is interesting because the KZ ZSN PRO X earns 15 out of 15, while the Soundcore Anker P20i earns 13 out of 15. The KZ is a passive wired earbud, so it has no battery and no need to recharge. Its connectivity is a 3.5mm analog jack with a detachable 2-pin cable. This means it works with any device that has a headphone jack, but it has no Bluetooth and no wireless codecs.
The P20i offers Bluetooth 5.3, which is current and stable, but the listing does not publish supported codecs. Its battery life is 10 hours from the earbuds and 30 hours total with the charging case. A 10-minute quick charge provides 2 hours of playback. This is a practical advantage for wireless use, but the battery will eventually degrade and need recharging, unlike the KZ.
The KZ's perfect score in this category reflects that a wired earbud has no battery anxiety and no pairing issues. However, that comes at the cost of being tethered to a source device with a 3.5mm jack. The P20i offers the convenience of wireless freedom and a long total battery life, but it depends on Bluetooth connectivity and charging. Buyers who need all-day wired reliability may prefer the KZ; those who want portable wireless use may prefer the P20i.
Build, Design and Portability
The KZ ZSN PRO X scores 7 out of 10 for build and portability, while the Soundcore Anker P20i scores 6 out of 10. The KZ uses zinc alloy faceplates and resin cavities, which give it a distinctive look and likely a more premium feel than all-plastic earbuds. The detachable 2-pin cable has groove protection, which the listing says helps with longevity. However, the KZ does not include a carrying case, so transporting it may require separate storage.
The P20i comes with a compact charging case that has an attached lanyard, making it easy to carry on a bag or wrist. The listing does not specify the case material or the earbud materials. The P20i is described as water-resistant, but the rating is not specified, which means we cannot compare it to an IP standard. The KZ has no water resistance rating published at all.
Both models have unknown weights, so portability cannot be fully judged by weight. The KZ's wired design means the cable must be managed, while the P20i's true wireless design is inherently more portable with the case. The one-point difference in favor of the KZ may reflect the build quality of the metal and resin construction plus the detachable cable. The P20i's unspecified water resistance and materials keep its build score slightly lower.
Call Quality and Daily Use
The KZ ZSN PRO X on this variant has no microphone and no inline remote, so it is not designed for phone calls or voice assistants. This is a significant limitation for daily use if you take calls or need to pause music without reaching for your device. The P20i includes AI call clarity with two microphones, which suggests better voice pickup during calls, although the listing does not provide detailed call quality specs.
For daily listening, the KZ requires a wired connection to a phone, laptop, or audio player with a 3.5mm jack. Many modern phones have removed this jack, so an adapter may be needed, but the listing does not include one. The P20i works wirelessly via Bluetooth 5.3, so it pairs with phones, tablets, and computers without a dongle. Its touch controls and app allow playback control, EQ changes, and finding lost earbuds.
The P20i is clearly more convenient for daily mixed use, including calls and portable listening. The KZ is better suited to stationary or wired listening sessions where a microphone is not required. Users who need a single pair of earbuds for calls, music, and commuting will likely prefer the P20i. Users who want a dedicated wired IEM for music or gaming may accept the KZ's lack of call features.
Who Should Buy It
Buy the KZ ZSN PRO X if you want a budget wired in-ear monitor with a hybrid dual-driver design. The listing describes one dynamic driver and one balanced armature, a detachable 2-pin cable, and up to 26 dB of passive noise isolation. This set of features appeals to wired-listening enthusiasts, gamers, and musicians who already have a 3.5mm source and do not need a microphone.
Buy the Soundcore Anker P20i if you want budget true wireless earbuds with punchy bass, long battery life, and app customization. The listing highlights the 10mm drivers, 30 hours of total battery with quick charge, Bluetooth 5.3, and 22 EQ presets in the soundcore app. It also offers AI call clarity and a compact charging case with lanyard.
Both models score 78 overall, so the choice depends on wired versus wireless and the importance of calls and app features. Neither model is a clear upgrade over the other; they serve different needs. If you are unsure, consider your daily source device and whether you can tolerate a cable.
The Deciding Question
The core question is whether you need wireless freedom with call and app features, or a wired analog connection with a hybrid driver and passive isolation. Both models score the same overall, so the answer rests entirely on your use case.
If you use a phone without a headphone jack and want to take calls, the Soundcore Anker P20i is the practical choice. If you use a dedicated audio player, laptop, or audio interface with 3.5mm and want a detachable cable for longevity, the KZ ZSN PRO X fits better.
There is no objectively better product here; each model has clear strengths and missing features. The P20i has unknown noise cancelling and codec details, while the KZ has no microphone and no Bluetooth. Decide based on what you cannot live without.
Who Should Buy Which
Choose the KZ ZSN PRO X for wired music listening, gaming, or stage monitoring where a detachable cable and hybrid driver matter. Its lack of microphone and Bluetooth is not a problem if you use an external mic or a dedicated wired setup.
Choose the Soundcore Anker P20i for everyday wireless use, commuting, or taking calls. Its battery life, quick charge, app EQ, and Find My Earbuds add convenience that the KZ cannot offer.
If you want both wired and wireless, these two are not interchangeable and you may need to consider a different product that includes both options. For budget buyers, choosing between them means accepting one set of tradeoffs.
