Soundcore P31i by Anker Translation Earbuds Review

Overview

The Soundcore P31i by Anker arrives as a budget-tier truly wireless earbud that refuses to act like one. Featuring adaptive active noise cancellation rated up to 52 dB, Hi-Res Audio Wireless certification with LDAC support, real-time AI translation across 100+ languages, and a total battery life of up to 50 hours, the P31i packs a specification sheet that would have been unthinkable at this tier just a couple of years ago.

Soundcore has built a reputation for delivering capable audio products that borrow features from premium alternatives and trim just enough to hit an accessible price point. The P31i continues that tradition, offering pared-down versions of capabilities typically found in more expensive earbuds from Apple, Sony, and Bose. Whether you need daily commuters, workout companions, or a backup pair you won’t be devastated to lose, the P31i aims to be the earbuds you reach for without hesitation.

After synthesizing multiple expert reviews and the available product data, here is a comprehensive look at what the Soundcore P31i brings to the table—and where it makes inevitable compromises.

Design and Build

The P31i uses a familiar stem-style design that Soundcore has stuck with across its product lineup. It is lightweight, simple, and practical. Nothing here reinvents the wheel, but nothing feels cheap either. The matte finish, particularly on the white version, looks clean and does not scream budget. EarbudsArena rated the design a 7 out of 10, noting that while minimal, it works well in practice.

Fit is an important consideration with any in-ear bud. The P31i sits slightly deeper in the ear than some users might expect. One reviewer found themselves going back and forth between medium and large ear tips—medium felt easier to wear for extended sessions, but large provided a better seal and noticeably improved sound quality. Getting the right tip matters more than usual here, as it directly affects both audio quality and ANC effectiveness.

The earbuds are available in Black, White, Blue, and Pink color options, giving buyers some aesthetic variety. The IP55 water and dust resistance rating means they can handle sweat and light rain without issue. NoFussDeal reported testing the IP55 rating with 12.5 liters per minute of water spray for three minutes, and the earbuds survived without problems. This makes them suitable for workouts and outdoor use, though they are not designed for submersion.

The charging case uses USB-C for power. Notably, there is no wireless charging support—a reasonable omission at this tier but worth noting if you have grown accustomed to dropping your earbuds on a Qi pad overnight.

Sound Quality

Audio performance is where the P31i generates the most discussion. The earbuds use dynamic drivers and support the LDAC codec, carrying Hi-Res Audio Wireless certification. LDAC allows for higher bitrate Bluetooth streaming, which can make a noticeable difference with high-quality source material. This feature remains rare in the budget segment and gives the P31i a genuine audio advantage over many competitors that only support SBC and AAC.

RTINGS.com measured the sound profile and found a warm signature with emphasized bass—about 4 dB above target—and slightly underemphasized treble at about 3 dB below target. This tuning favors genres like pop, electronic, and hip-hop, where bass presence is welcome. The warm signature means these are not reference monitors, but they are tuned for enjoyment rather than analytical listening.

The consensus across reviewers is that the P31i delivers crisp highs, full mids, and bass that shows up without overwhelming the rest of the mix. One reviewer who owns Sennheiser HD660s and Grado SR80s—serious home listening gear—called them the best true wireless earbuds they had ever used and said they would pay significantly more for them without hesitation. A musician with 30 years of gigging experience found them quite enjoyable for on-the-go listening, specifically noting their ability to reproduce subtle details like background guitar tracks and syncopated percussion.

However, not everyone was immediately impressed. EarbudsArena gave sound quality a middling score, calling it average out of the box but noting that it grows on you quickly once you spend time with the app’s EQ tools. The sound quality transformation through the app is significant enough that multiple reviewers reported the experience jumping from good to amazing after customization.

Adaptive ANC Performance

Active noise cancellation is one of the P31i’s headline features. The earbuds offer adaptive ANC that can reduce noise by up to 52 dB, with technology that detects your surroundings and automatically selects the appropriate noise-cancelling level. NoFussDeal measured the ambient noise reduction at approximately 28 dB in their testing, with transparency mode switching in 0.3 seconds. The difference between the maximum figure and the measured figure likely reflects the distinction between peak reduction in ideal conditions versus typical real-world performance.

Real-world ANC performance drew mixed but generally positive feedback. Reviewers tested the adaptive cancellation in various challenging environments: public transit, busy offices, next to a lawn tractor, and even in bed next to a snoring partner with active construction outside. One side sleeper reported wearing the P31i from 10:30 PM to nearly 10 AM with ANC engaged, hearing nothing—a genuine stress test that most product listings do not cover.

When compared directly to premium alternatives, the P31i lands at roughly 90% as effective as AirPods Pro, according to one reviewer’s blunt assessment. Office chatter fades and HVAC hums disappear, but Apple’s deeper iOS integration gives AirPods an ecosystem advantage that Soundcore cannot fully replicate. The Soundcore app provides adjustable ANC settings, allowing users to fine-tune the experience rather than relying solely on the adaptive mode.

ZDNET’s review was more critical, suggesting that buyers should look elsewhere for effective ANC. This represents the more negative end of the spectrum, and it is worth noting that ANC expectations are highly subjective. What one reviewer finds adequate, another may find lacking. The adaptive system does adjust automatically, which means performance varies depending on your specific environment and the type of noise you are trying to block.

AI Translation Feature

One of the P31i’s most distinctive features is its real-time AI translation capability. The earbuds can translate speech across over 100 languages, with AI providing instant translation designed to keep conversations smooth and natural. NoFussDeal reported a processing latency of approximately 0.5 seconds, which is fast enough for practical conversation without awkward pauses.

The translation feature works through the Soundcore app, meaning your phone needs to be connected and the app active during use. This is not a standalone feature built into the earbuds themselves—it relies on cloud processing through your connected device. For travelers, this could be a genuinely useful tool for navigating foreign-language environments, though it is worth managing expectations. AI translation, while impressive, is not perfect and may struggle with idioms, accents, and rapid speech.

ZDNET noted that the earbuds are packed with AI features, with translation being a standout. The feature’s inclusion at this tier is notable, as translation capabilities have typically been reserved for more expensive smart earbuds or dedicated translation devices.

Call Quality and Microphones

The P31i is equipped with six AI-enhanced microphones that work with a noise reduction algorithm to separate your voice from background noise. A dedicated wind-noise reduction algorithm is designed to keep calls clear even in outdoor conditions.

RTINGS.com recommended the P31i in their Earbuds For Phone Calls and Earbuds With A Mic categories, suggesting the call quality is competitive within its segment. The six-microphone array is more than what many budget earbuds offer, and the AI processing aims to maintain voice clarity in challenging acoustic environments. While the available sources do not provide detailed call quality measurements, the inclusion in RTINGS’ call-quality recommendation lists speaks to adequate real-world performance.

Battery Life and Charging

Battery life is where the P31i genuinely excels and arguably leads its class. The earbuds deliver up to 10 hours of playtime on a single charge, extending to 50 hours total with the charging case. Even with ANC active, you get 8 hours per charge and 40 hours total. These numbers put many premium alternatives to shame and eliminate the daily charging anxiety that plagues most truly wireless earbuds.

Fast charging is equally impressive. A 10-minute charge provides approximately 3 to 3.5 hours of listening time, depending on the source. This means a quick top-up while getting ready to head out can provide enough power for a substantial listening session. The convenience of this feature cannot be overstated for anyone who has ever grabbed their earbuds on the way out the door only to find them dead.

Real-world battery performance has drawn enthusiastic feedback. One reviewer reported using the P31i for three weeks of daily, multi-hour use and only draining the battery to 40% before plugging in for the first time. That kind of endurance means you can genuinely forget about charging for extended periods—a quality that is increasingly rare in the truly wireless space.

App and Features

The Soundcore app is central to the P31i experience. It provides access to firmware updates, HearID personalized sound profiling, EQ modes, Spatial Audio, and adjustable ANC settings. The app also enables the AI translation feature and offers customizable controls.

The HearID system is a particular standout. It runs an A/B preference test—playing variations of the same song and asking which sounds better—to build a personalized sound profile tailored to your hearing. Multiple reviewers reported that sound quality jumped significantly after completing this test. Pre-built profiles like Acoustic and Electronic provide starting points, and full manual EQ tweaking is available for users who want deeper control.

However, the app experience is not universally praised. ZDNET noted that the app could be a little more intuitive, and one reviewer found the auto-EQ test a bit underwhelming, needing to manually dial in settings to unlock the earbuds’ full potential. The tools are there, but getting the best results may require some patience and experimentation rather than relying entirely on automatic tuning.

The app also supports OTA firmware updates, which means Soundcore can add features and fix issues over time. Bluetooth 6.1 with multipoint connection allows pairing with multiple devices simultaneously—a feature that is becoming increasingly expected and is welcome at this tier.

Expert Comparisons

RTINGS.com placed the P31i in numerous recommendation categories, including Budget and Cheap earbuds, Noise Cancelling Earbuds, In-Ears, Earbuds For Phone Calls, Earbuds For Bass, and notably, AirPods Alternatives. The warm sound profile with emphasized bass makes it particularly suitable for bass-forward music genres.

The comparison to AirPods Pro came up repeatedly across sources. The P31i delivers roughly 90% of the ANC effectiveness of Apple’s premium offering, according to one reviewer. ZDNET’s reviewer explicitly framed the P31i as a practical replacement for lost AirPods Pro, noting that they serve as an accessible alternative to replacing individual AirPods Pro earbuds. While the ecosystem integration cannot match Apple’s deep iOS ties, the standalone feature set is remarkably competitive.

The inclusion of LDAC support is particularly noteworthy. This high-resolution codec is typically found in more expensive earbuds, and its presence here gives the P31i an audio quality advantage over many competitors in its segment. The 40 kHz frequency extension noted by NoFussDeal further supports the Hi-Res certification claim.

What Customers Are Saying

With a 4.4 out of 5 star rating across nearly 9,000 ratings on Amazon, the P31i has generated substantial positive feedback from buyers. While detailed customer review text was not available for analysis, the high rating volume and score suggest broad satisfaction across a large user base.

The aggregate rating aligns with expert reviewer sentiment. The P31i earned a 5.0 from cprice.co, a 4.6 from NoFussDeal, a 3.5 out of 5 from ZDNET, and a 7.0 out of 10 from EarbudsArena. This spread reflects the product’s nature: it impresses users who adjust expectations for its tier, while some reviewers find specific aspects lacking compared to premium alternatives.

The strongest praise centers on sound quality after app customization, battery life, and the surprising effectiveness of adaptive ANC for the price. The most common criticisms relate to average out-of-the-box sound that requires app tuning, the lack of wireless charging, and ANC performance that, while good for the tier, does not match premium alternatives.

Verdict

The Soundcore P31i by Anker is a compelling package that redefines expectations for budget truly wireless earbuds. It takes features that were exclusive to premium models—adaptive ANC, LDAC support, AI translation, spatial audio—and packages them in a practical, comfortable design with genuinely outstanding battery life.

The compromises are real but predictable for the tier. Out-of-the-box sound is merely average until you spend time with the app’s EQ tools. ANC is effective but not class-leading. The app could be more polished. There is no wireless charging. These are trade-offs that informed buyers should expect and accept.

What makes the P31i special is how much it gets right. Once you have dialed in the EQ to your preferences, the sound quality can genuinely surprise—even impressing audiophiles who own dedicated home listening gear. The battery life eliminates charging anxiety for days at a time. The adaptive ANC handles most real-world environments adequately. And the AI translation feature, while not perfect, adds genuine utility for travelers that no other earbud at this tier offers.

For anyone seeking a capable daily driver without the premium price tag, or a backup pair that you will not be devastated to lose, the P31i is easy to recommend. It earns its place in RTINGS’ recommendation lists across multiple categories, and the near-9,000 Amazon ratings averaging 4.4 stars suggest the broader market agrees. Pricing varies, so check the product page for current availability and cost.
