Overview

The Kiisda M31 96GB 4-Inch Touchscreen MP3 Player is essentially a stripped-down Android device built around one purpose: letting you enjoy music, podcasts, and streaming apps without needing your phone nearby. It ships with a 64GB microSD card already inserted, bringing total usable storage to 96GB right out of the box. The 4-inch screen gives it enough real estate for video and app navigation, and Wi-Fi support means you can pull up Spotify or Audible without a cellular plan. For the price, the package is surprisingly complete — case, earphones, and charging cable included. It occupies a clear niche for people who want a dedicated media device without the complexity or cost of a smartphone.

Features & Benefits

Where this MP3 player earns its keep is in the breadth of what it can actually do. The dual-band Wi-Fi — covering both 2.4GHz and 5GHz — gives you a stable connection for app downloads and streaming, which matters when you are trying to sync a Spotify playlist over a congested network. Bluetooth handles wireless audio output to headphones, speakers, or your car stereo without any fuss. The screen handles video playback across a wide range of formats, including MKV and MP4, so you won't need to re-encode files before transferring them. FM radio is a quiet but practical addition for times when streaming isn't an option. Storage is expandable up to 1TB, and the player supports lossless audio formats like FLAC and WAV — useful if you keep high-quality local files.

Best For

This portable media player makes the most sense for a few specific types of buyers. Parents who want to give kids a device for entertainment without handing over a smartphone will find it practical — it's capable enough to hold their attention without the full distraction of a phone. Gym and outdoor users who prefer not to carry their phone during a workout will appreciate having music and podcasts on something light and dedicated. Audiobook fans who rely on Audible or podcast apps daily can use it as a standalone listening device over Wi-Fi. It also works well for travelers who want offline playback on long trips. That said, buyers expecting a true smartphone replacement will likely be disappointed — its strengths are focused, not broad.

User Feedback

With a 3.9 out of 5 rating across 58 reviews, the Kiisda M31 tells a familiar story for budget Android devices: buyers who go in with realistic expectations come away reasonably satisfied, while those expecting flagship-level polish tend to be let down. The most consistent praise centers on accessory value — the included earphones, silicone case, and SD card are appreciated as genuinely useful additions. On the downside, some owners report that app compatibility can be inconsistent, with Google Play access not always working as expected. The Android interface can also feel sluggish under heavier use, which is worth knowing upfront. Sound quality through the wired earphones gets a modest thumbs-up from most, though the built-in speaker is described as functional rather than impressive.

Pros

  • Ships with a 64GB SD card already installed, giving you 96GB of usable storage right out of the box.
  • Dual-band Wi-Fi support means stable streaming and app downloads even on busier networks.
  • Bluetooth connectivity works with wireless headphones, speakers, and car stereos without extra setup.
  • Supports a wide range of audio formats including FLAC and WAV, which matters for local library listeners.
  • Video playback handles MKV, MP4, and other common formats without requiring file conversion.
  • The included accessories — earphones, silicone case, and charging cable — add real day-one value.
  • Storage is expandable up to 1TB via microSD, giving the device a long practical lifespan.
  • FM radio provides a no-internet fallback for listening when streaming is not available.
  • A focused, phone-free device helps gym users and commuters stay present without smartphone distractions.
  • At its price point, the overall feature set is hard to match for casual listeners and light media users.

Cons

  • App compatibility is hit-or-miss; Google Play access has been unreliable for some buyers.
  • The Android interface can feel noticeably sluggish when running streaming apps or switching between tasks.
  • The built-in speaker delivers acceptable volume but lacks any real depth or clarity for music.
  • With only 3GB of RAM, demanding apps may stutter or crash under heavier use.
  • No cellular connectivity means this player is fully dependent on available Wi-Fi for streaming.
  • The HiFi branding on the speaker is a marketing label and should not set high audio expectations.
  • A relatively small owner base of 58 reviews makes it harder to assess long-term reliability confidently.
  • Sound quality through the included earphones is adequate but unlikely to satisfy more discerning listeners.
  • The Android version is not disclosed clearly, which raises questions about app support and future updates.
  • At 8.8 ounces, it is not the lightest option for users who want something pocket-friendly during workouts.

Ratings

The Kiisda M31 96GB 4-Inch Touchscreen MP3 Player has been scored across key performance categories by our AI rating system, which analyzed verified global buyer reviews while actively filtering out incentivized, bot-generated, and spam feedback. The scores below reflect a balanced picture — genuine strengths are recognized, and recurring frustrations are not softened or buried. If you are weighing this device against alternatives, these ratings give you an honest, data-driven starting point.

Value for Money
83%
For buyers who just want a capable media device without paying smartphone prices, the overall package is hard to argue with. Getting 96GB of usable storage, Bluetooth, dual-band Wi-Fi, and a bundle of accessories at this price tier earns consistent appreciation from reviewers who set realistic expectations going in.
Those who compare it to entry-level Android phones in a similar price range sometimes feel the performance does not justify even the modest outlay. If you stretch your budget slightly, competing devices offer a noticeably smoother experience that makes the value equation less clear-cut.
App Compatibility
58%
42%
The pre-loaded app store does cover popular choices like Spotify and Audible, and for buyers who stick to those mainstream apps, day-to-day usability is workable. Some technically confident users have successfully sideloaded additional apps, expanding the device's reach beyond the default storefront.
Google Play availability is genuinely inconsistent — a meaningful number of buyers find it missing or unreliable, which is a real problem if your preferred apps are not in the built-in store. This is arguably the single biggest practical limitation and one that surprises buyers who assumed full Android app access was guaranteed.
Performance & Speed
54%
46%
For simple tasks like playing local music files, browsing a playlist, or listening to an audiobook, the 8-core processor handles the workload without obvious struggle. Users who treat this as a single-purpose playback device rather than a multitasking hub tend to report fewer complaints about speed.
With only 3GB of RAM, the Android interface starts to drag noticeably when switching between streaming apps or running anything moderately demanding. Buyers accustomed to a current-generation phone will find the lag frustrating rather than tolerable, and it is a consistent thread throughout critical reviews.
Audio Quality
67%
33%
Through a decent pair of wired headphones or Bluetooth earbuds, the Kiisda M31 delivers a listenable experience that covers most casual needs — commuting, light exercise, or background listening at home. Support for lossless formats like FLAC and WAV is a genuine plus for buyers who store high-quality local files.
The HiFi labeling on the product is a marketing decision, not a technical certification, and the built-in speaker underscores that reality — volume is adequate but the sound is thin and lacks any real bass response. Wired earphone quality receives mixed feedback, with most buyers noting they are functional but not impressive enough for extended critical listening.
Storage & Expandability
91%
Shipping with a 64GB card pre-installed and supporting expansion up to 1TB via microSD makes this one of the most storage-flexible devices in its category. For buyers with large local music or audiobook libraries, this is a standout practical advantage that few similarly priced competitors can match.
The 32GB internal ROM sounds generous but the Android system and pre-installed apps consume a meaningful share of it, leaving less free space than buyers initially expect. Clarity on how much internal storage is genuinely available after the OS takes its portion would help buyers plan their storage use more accurately.
Connectivity
78%
22%
Dual-band Wi-Fi covering 2.4GHz and 5GHz gives this portable media player a stability edge over devices limited to 2.4GHz, which matters when streaming in hotels or other congested network environments. Bluetooth pairing with speakers and car stereos works reliably and adds a useful layer of flexibility for daily use.
There is no cellular connectivity whatsoever, meaning the device is entirely dependent on available Wi-Fi for any streaming or app-based content. For buyers who assumed they could use it on the go without Wi-Fi — similar to a phone — this is a significant functional limitation worth understanding before purchasing.
Included Accessories
86%
The out-of-box package — earphones, silicone case, charging cable, and a pre-inserted 64GB SD card — is consistently praised in buyer reviews as a genuine value add. Most competing devices at this price ship with far less, and arriving ready to use without needing to buy accessories separately makes a real first impression.
The included earphones are basic and rarely satisfy buyers beyond initial use, with most gravitating to their own headphones fairly quickly. The silicone case offers basic scratch protection but provides minimal drop resistance, so buyers who plan to use this at the gym or outdoors should consider a more protective option.
Screen Quality
71%
29%
The 4-inch touchscreen is comfortably sized for navigating menus, browsing an app interface, or watching a short video during a commute. Touch response is generally described as adequate, and the screen real estate is a genuine upgrade over the tiny displays found on traditional iPod-style players.
Brightness and color accuracy are typical of budget Android displays — acceptable indoors but harder to read in direct sunlight, which matters for outdoor users. Buyers hoping for a sharp, vibrant viewing experience for video content will find it underwhelming compared to even a mid-range phone screen.
Build Quality
63%
37%
The device feels reasonably solid in hand for its price tier, and the silicone case adds a layer of grip that makes it easier to hold during a workout or commute. The physical button layout is straightforward and does not feel flimsy in everyday handling.
The overall construction reads as budget plastic, and there is no mention of any water or sweat resistance — a notable gap for gym users who might expose it to moisture. Several buyers note the device feels lighter and less premium than the product images suggest, which can be a mild disappointment on unboxing.
Ease of Setup
74%
26%
For users already comfortable with Android devices, getting this player up and running with Wi-Fi, a streaming app login, and Bluetooth headphones is a straightforward process that takes only a few minutes. The pre-installed apps reduce the initial setup burden compared to a completely bare-bones device.
Buyers less familiar with Android — such as older users or those coming from a traditional MP3 player background — may find the interface less intuitive than expected, particularly when navigating the app store or configuring Wi-Fi settings for the first time. Clear setup documentation is not a strong point of the package.
Portability
76%
24%
At roughly 5.35 inches long, this portable media player slips into a jacket pocket or small bag without much effort, and the included case keeps it protected during daily carry. For commuters or travelers, it is compact enough to be a genuine everyday companion without adding bulk.
At 8.8 ounces it is noticeably heavier than ultra-compact sport players, which becomes apparent during longer runs or workouts where weight and clip-free carrying start to matter. Buyers specifically looking for a featherlight gym device may want to factor this into their decision.
FM Radio
79%
21%
The built-in FM radio is a quietly useful feature that several buyers highlight as a reason they chose this device over alternatives — it gives you a no-internet listening option that works anywhere with a signal. For commuters in areas with strong local broadcast coverage, it adds meaningful everyday utility.
FM radio performance is inherently dependent on local signal strength and antenna design, and the wired earphones typically serve as the antenna, meaning you need them plugged in to get consistent reception. This limits your listening flexibility when you would prefer to use Bluetooth headphones instead.
Battery Life
61%
39%
For shorter listening sessions — a gym workout, a daily commute, or a few hours of audiobook playback — the battery holds up without issue, and the device charges via a standard cable that is easy to replace. Most casual users report getting through a typical day of intermittent use on a single charge.
Kiisda does not publish an official battery capacity or rated playback hours, which makes it difficult to plan around and is a transparency gap buyers should know about. Users who stream heavily over Wi-Fi with the screen on report noticeably faster drain, and there is no low-power or offline mode to extend runtime.
Video Playback
77%
23%
The ability to play MKV, MP4, MOV, and other common formats directly without conversion is a genuinely practical feature for travelers who load up local video files before a flight. The 4-inch screen handles this well enough for personal viewing, and format compatibility is broader than many devices in this category.
Streaming video from services like Netflix is not a reliable use case here given the app compatibility uncertainties, so video utility is largely limited to locally stored files. The screen size also caps how enjoyable longer movie watching actually is — it is better suited to short-form content than full-length films.

Suitable for:

The Kiisda M31 96GB 4-Inch Touchscreen MP3 Player is a practical pick for anyone who wants a capable media device without the cost or distraction of a full smartphone. Parents who want to give their kids access to music, audiobooks, and educational apps — but not social media or data plans — will find it a reasonable middle ground. Gym-goers and runners who prefer to travel light will appreciate having a dedicated device for their playlists and podcasts without draining their phone battery. Audiobook fans who live inside Audible or podcast apps can set this up as a standalone listening companion over any available Wi-Fi network. It also works well for travelers who load up local files before a long flight and want offline video and music playback without relying on a cellular connection.

Not suitable for:

Buyers expecting a smooth, modern Android experience should know upfront that the Kiisda M31 is a budget device, and it behaves like one. With only 3GB of RAM, multitasking between streaming apps and other functions can feel sluggish, and users accustomed to a current-generation phone will likely notice the performance gap immediately. Google Play availability has been flagged as inconsistent by some buyers, meaning certain apps you depend on might not install or run reliably. The built-in speaker is functional but not something you would choose for serious listening — it covers the basics and little more. Anyone hoping to replace a smartphone entirely, or who needs dependable access to a wide range of Android apps, would be better served by spending more on a certified Android device rather than working around the limitations this player presents.

FAQ

Spotify is listed as a supported app and may come pre-installed, but you should expect to log into your own account and potentially update the app via the built-in app store. Streaming will require a Wi-Fi connection since there is no cellular radio on board.

This is one of the more common questions buyers have, and the honest answer is: it depends. Some users report being able to access Google Play, while others find it unavailable or unreliable. The device comes with its own app store, which covers many popular apps, but if you rely specifically on Google Play for a particular app, you may want to confirm compatibility before purchasing.

The device ships with 32GB of internal ROM and a 64GB microSD card already inserted, so you are looking at roughly 96GB total. Keep in mind that the Android operating system and pre-installed apps will consume a portion of the internal storage, so the full 32GB will not all be available for media files. The SD card storage, however, is largely free for your use.

Yes, it does. You can pair it with any standard Bluetooth headphones or speakers. It also works with car stereos via Bluetooth, which is handy if you want to use it as an in-car audio source without an AUX cable.

It can handle music, videos, audiobooks, and Wi-Fi-connected apps, so it covers most entertainment needs for a child. However, it has no cellular capability, meaning no calls or texts. That actually makes it appealing for parents who want to give kids a capable media device without handing over full phone access.

It is decent for casual listening, especially through the included wired earphones or a good pair of Bluetooth headphones. The built-in speaker handles background listening fine but is not something you would use for serious music enjoyment. The HiFi labeling on the product is more of a marketing term — set your expectations accordingly and you likely won't be disappointed.

The battery is a built-in Lithium Polymer unit, so it is not user-replaceable. Kiisda has not published an official battery life figure in hours, which is a notable omission. Based on the device type and processor, expect performance in line with similar budget Android media players, though real-world results will vary depending on screen brightness and whether you are streaming or playing local files.

It depends on the app. The player can handle locally stored video files in a wide range of formats without any conversion needed. However, downloading content from services like Netflix for offline viewing requires those apps to be installed and certified on the device, which is not guaranteed given the inconsistency around app compatibility on this platform.

It comes well-equipped out of the box. The package includes a wired pair of earphones, a silicone case, a charging cable, and the 64GB microSD card already inserted in the player. You can start listening immediately without buying anything extra, though you may want to upgrade the earphones over time if audio quality matters to you.

Your options are limited but not zero. Some users sideload APK files from trusted sources, which works on Android devices that allow installation from unknown sources. That said, this requires some comfort with Android settings and carries a small security risk if you are not careful about where you source the APK. If a specific app is critical to your use, it is worth researching compatibility before buying this portable media player.
