MP3 Player with Bluetooth and WiFi, Android 5" IPS Music Player, Supports Custom APK Installation, Spotify, Audible, Pandora, Apple Music, Amazon Music,up to 1 TB

I would give this product 10 stars if I could. I have bought several as gifts. The interface is orderly, functional & attractive. The machine does not stall & extremely rarely, if ever, crashes. I had a technical problem & emailed the customer services & they provided high quality, helpful & straightforward intruction. The playback quality over earphones or a secondary speaker on this machine is fantastic. The in built small speaker is also very useful. I like to play it on the small, in built speaker very quietly as I go to sleep. The machine has a bluetooth function plus a physical aux socket. The machine works seemlessly with a 1tb micro sd card installed & the extra internal memory is useful for downloading data for the included aps. Overall, for this quality of media player, the price is amazing. As the world gets more crazy, there are nonetheless some nice things about living in the present day. This well engineered product has brought me a lot of joy.

I received the replacement on my first purchase.The product listing cites “up to 1TB Micro SD Card” can be used for expanded storage. It sounds great. BUT…all micro SD cards require the PECSU P5S to be formatted in the player before loading your mp3 music files on to it. The P5S formatting limits (restricts) the number of mp3 files to a range from 9,600 to 9,900 files (about 70GBs). Thus, if you have a large collection of mp3 files (60,000), you are SOL!THIS WAS CONFIRMED TO ME VIA AN AMAZON EMAIL FROM PECSU.One must question why PECSU has purposefully misrepresented the ability & capacity of its P5S product.None of the “so-called” independent product reviewers caught this obvious problem of only being able to access & use 7% of a 1TB Micro SD CD.THERE ISN'T ANY EXPANDED STORAGE WHEN YOU ONLY CAN ACCESS 7% OF A 1TB MICRO SD CARD!Something else that bothered me is that the data in each mp3 file properties appear to be ignored. The filing system should be easy to understand but it isn’t. It takes some time to figure out. How can PECSU screw up the selection process by not using a file’s properties?Other than those 2 major items, I liked the size & several of the options available on the PECSU P5S. BUT, THE PRODUCT LISTING WAS MISLEADING FOR A KNOWN LIMIT (RESTRICTION).PREVIOUS COMMENT.I am disappointed with my PECSU P5S, BUT I like it. I like the size. I like the possible options.BUT… IT DOES NOT PERFORM AS IT IS ADVERTISED!I have a library of about 100,000 audio files. So, the expanded Micro SD Card to 1 TB is very appealing. BUT, when I format the card in the P5S & then remove it to load my audio files only about 9,800 files can be loaded before receiving error. At that point, no additional files can be loaded.I have written & sent 3 emails to PECSU within a week of receiving the player.I did receive a response after 5 days to one of my emails. It stated, “we are referring your problem to our technical staff”. That response was 12 days ago.I did chat with an Amazon representative. A summary of the chat is: “you should email the company.”Of the about 9,800 audio files that I have been able to load, I am very happy with the player.However, the filing system for accessing the audio files takes some time to figure out. The filing system is much more complicated than it needs to be. It appears that the file properties are ignored by the filing system.The PECSU P5S COULD BE A REALLY GREAT PRODUCT BUT IMPROVEMENTS NEED TO BE MADE!

In the past 5 months I have been “on a mission” to find a suitable mid-level MP3 Player. I am not so much an audiophile that I want to fork over +$150 for the DAC style MP3 player but I was hoping to find a player in the $50 range that provided good battery life, small form factor and ease of use. I realize of course that one can use their phone as a suitable MP3 player, but I find that good quality phones that I enjoy using to be +6” in size which for me is too large to use as a stand-alone MP3 player.My MP3 Player testing has included the following units (all of which have received high marks on Amazon) which range in listed order below in terms of their cost (from the low $30s to $80):- MECHEN 32GB MP3 Player- BERENNIS BT 5.2 MP3 Player- JOLIKE BT 5.0 MP3 Player- TIMMKOO Q5 4.0” BT MP3 Player- Louran M4 4” MP3 Player- Louran M4 Pro 4” MP3 Player- Innioasis G1 4” MP3 PlayerOf all the players that I have tested I’ve found the players which use a version of the Android OS to be the most user friendly and allow for the most versatility. Players that use a version of the Android OS that I have tested includes MP3 Players from TIMMKOO, Luoran (both M4 and M4 Pro) and the Innioasis G1.This review is for the PECSU P5S 5” MP3 Player (3GB RAM/32GB storage). This review will also include a comparison to the PESCU P5S’s nearest competitor: the Louran M4 Pro (4” screen with 2GB RAM/16GB storage). If you’re interested in a thorough review of the M4 Pro I have supplied one on its Amazon product page.Build QualityI find the P5S’s construction to be very similar to the Luoran M4 Pro (metal frame with back plate that is of glass construction). It is heavier (due to the increase in its screen from 4” to 5”) but similar in thickness. The P5S is squarer with its edges being a little sharper compared to the M4 Pro. I would have preferred the edges to be more curved to make it more comfortable in the hand.Both have:1. Their buttons and mic in similar locations (a volume up/down toggle, a power button and a mic on the right side of the player). The buttons on the P5S are a little more clicky vs. the M4 Pro.2. A SD card reader on the lower left side of the player (when a microSD card is inserted it sticks out a little father in the slot vs. the M4 Pro, but this allows it to be much easier to install and remove)3. Two (2) 3.5mm headphone ports and a USB C charging port on the bottom4. Speaker grill(s) on the bottom of the player. While the M4 Pro only has one speaker grill the P5S has two. I’m not sure if that means the P5S has two downward firing speakers or not.Both the P5S and the M4 Pro are completely sealed. There is no way for the user to open the unit to access the interior rechargable battery. This means if/when the battery dies the unit will need to be disposed. The inability to access the battery is universal for many phones and MP3 Players nowadays which is unfortunate.Of all the MP3 players that I tested, the P5S comes with the largest battery (2,500 mAh) vs. the M4 Pro (2,000mAh). I do like that the P5S provides accurate playtime information on its Amazon page indicating 15 hours of playtime (if using wired headphones) and 5 hours of video watching (they don’t indicate the brightness level for this stated time). Other similar MP3 Players marketed on Amazon provide overblown estimates of their playtime and don’t mention that you can receive this playtime if used the player in “lab conditions” which consist of using wired headphones, with WiFi, BT and the screen off.Both the P5S and M4 Pro comes in one color (black). In terms of durability the similar TIMMKOO 4” Q5 MP3 Player has a plastic frame on the sides and around the back, making it much lighter and allowing it to be available in multiple colors. Since the case is plastic, the TIMMKKOO Q5 is also more durable overall. More than likely, if you dropped either the P5S or the M4 Pro the glass would crack rather easily. Unfortunately, neither vendor provides a protective case and there are not third-party case options to protect these MP3 Players. Individuals that are more active and will use this MP3 player for running, walking, working out or other activities may want to take that into account.In terms of build quality there was very little difference between the P5S and the M4 Pro that I noted. I did note that the back of the P5S got a bit warmer in temperature when used compared to the M4 Pro but not overly so. The additional headphone port in both units is a very strange design choice and I can say that I’ve never had the desire to share my MP3 player with someone else where I’d want myself and another person to be tethered to one MP3 player via wired headphones. Maybe there is an interest in adding this for the younger generation.AccessoriesBoth the P5S and M4 Pro came with:- wired headphones- USB-C cable- USC-C to USB-A adaptor (the P5S came with an additional USB A 2.0 adapter to allow for faster file transfer)- Screen Protector- User manualDisplayThe P5S provides the largest screen size that I’ve seen marketed for Android type MP3 Players (5”). The M4 Pro comes with a 4” screen. Both provide IPS type displays which provide a decent viewing experience. The colors are vibrant, and the contrast is decent. The screen resolution of the P5S is 480 x 854 (240 PPI). The viewing angles aren’t all that great but due to the size of these players the user would typically be looking at it head on so viewing angles (or lack thereof) should not be a big deal. The brightness level for both players is good. There are no specs provided regarding the NITS or lumens the unit provides but I would estimate it is between 300-350 NITS for the P5S. My recollection is that the brightness is slightly less for the M4 Pro. Both screens are difficult to read in direct sunlight, but you should be able to view either one comfortably in shady areas and will have no issues in bright indoor environments. I did notice that the M4 Pro unit that I purchased had air pockets underneath the screen which is unfortunate and suggests poor QC during manufacturing.While both the P5S and M4 Pro provided screen protectors as an accessory neither one provided instructions on how to install them. Neither also provided suitable cleaning wipes to make sure dust is not captured when installing the screen protector. I would strongly suggest individuals thoroughly clean the glass and then use alcohol wipes before applying the screen protector to minimize the amount of air bubbles that form underneath the screen protectors.One of the main differences is with the onboard sensors. The P5S provides an accelerometer (which allows you to use games that require the player to have left/right/forward/reverse movement by tilting the phone and/or for the use of a compass) while the M4 Pro provides a gravity sensor (which allows for picture orientation to auto correct). Unfortunately, I didn’t see anywhere with the M4 Pro in which the gravity sensor was put to good use.The increased screen size of the P5S definitely comes into play when viewing videos and playing games. If you are interested in a smaller form factor and are only interested in using this type of product as a MP3 player, I believe the 4” display of the M4 Pro is better suited.Sound QualityAs mentioned, both the P5S and M4 Pro come with their speaker on the bottom edge of the player. The P5S has two speaker grills while the M4 Pro only has one. The sound level may be slightly louder with the P5S vs. the M4 Pro but since the speakers are so close together and firing down (or to one side if watching a video) I detected no stereo type sound. The sound quality of both the P5S and M4 Pro speakers are serviceable and does allow you to listen to movies/audio in a quiet environment though it does not provide any bass and is a bit tinny in sound. I have definitely heard worse speakers when testing these MP3 players (if they include one) and would rank the speaker quality for the PS5 and M4 Pro the best of all the units I’ve tested.Similar to other units I have tested there is no global equalizer on the P5S or M4 Pro. If the app includes an equalizer, you will have it available. I wish both players provided the ability to pump out louder sound through the headphones (either wired or through BT connection). I do not know if less sound is provided when both headphone ports are used together as I didn’t test the unit with two wired headphones in use. The wired headphones that both players are shipped with are substandard and I would very much suggest you to replace them with better quality headphones and chuck the included wired headphones into the “junk drawer.”The onboard mic on both the PS5 and the M4 Pro works but captures audio at low levels. I do not believe it could be used as a sufficient recorder for interviews or dictation due to its lack of sensitivity. The PS5 also provided worse voice clarity vs. the M4 Pro.Bluetooth and WiFi rangeI had no issues connecting to various wireless headphones using either player. The P5S uses more advanced BT technology (5.0) vs. the M4 Pro (4.2). I did get better BT range with the P5S vs. the M4 Pro which is to be expected since it has a better BT chip within it.The included WiFi range was solid and had no issues getting a good signal one floor up. The P5S has both 2.4Ghz and 5Ghz antennas allowing you to get much higher data streaming vs. the M4 Pro if you are near a 5Ghz signal. I did verify that both antennas exist using the WiFi Analyzer App and saw data streaming above 70 Mbps when connected to my 5Ghz SSID using a speed test app. Unfortunately, the M4 Pro is only built with a 2.4Ghz WiFi antenna but I was able to get 30Mbps one floor up.Storage, RAM and CPUThe P5S has the highest hardware specs of all of the Android MP3 Players that I have tested. The onboard 32GB storage provides you plenty of room to add video files, apps or music files. The included 3GB of RAM is more than enough and I saw over 1.5GB of free RAM when the P5S is running “idle.” I did install a device info app to try and find additional information on the hardware. The P5S is reported to have MediaTek MT6753 chipset. Info on this chip is as follows:“MediaTek MT6753 is a 64-bit octa-core WorldMode 4G LTE® platform based on the ARM® Cortex® -A53 64-bit processor with ARM Mali™ -T720 graphics”Geekbench 5 testing provided the following results: Single core = 111; Multi-core = 396. Obviously this GB5 score isn’t going to win any awards for its CPU scores but it’s fast enough to perform well as a MP3 Player and/or video player (which is what it’s marketed to be). You should note that this player will have issues playing higher end Android games due to the type of CPU and integrated GPU that resides in its chip. High end tablets and phones reach GB5 scores up to 10x higher than this Player. The P5S is capable of running less intensive games though. Compared to the M4 Pro (which has a similar CPU but only 16GB of storage and 2GB of RAM) the P5S is a definite step up. With the extra storage and RAM this means you can have additional space for apps and additional RAM to run several apps at the same time.Operating SystemBoth the P5S and the M4 Pro use a modified lite version of Android 8.1 (Oreo). I did notice that the M4 Pro took half the time to boot up (10 sec) vs. the P5S (20 sec). Both showed good responsiveness with opening and closing apps. Both incorporate an auto shutdown timer to help with battery life. The settings for the auto shutdown are Never, 5, 10, 15 or 20min. If the device is set for one of the shutdown times listed it will effectively completely shut down if it detects no activity necessitating a complete restart when the user begins to use it again. This is a great addition to help the user save battery life for these devices. The biggest different between the two in terms of OS capabilities is that the P5S allows for files to be downloaded and APK to be installed. The M4 Pro is completely locked down disallowing the user to upgrade current apps or install new ones (more on that below).Both players are shipped with the same launcher (Launcher3). This launcher allows for app icons to be grouped and wallpaper to be changed but not much else. It has several docked apps (apps you see no matter what homepage you are own) which is APlayer, File Manager, Settings and MiniShare (WiFi sharing App). You cannot add new homepages and you cannot add app widgets. I was not pleased with Launcher3 as it provides very little customization which I’m used to when using a Android device. Luckily for the P5S you can add new launchers (more on that below). With the M4 Pro you are stuck using the Launcher3.App testingThe P5S and M4 Pro are very similar in regard to the apps the vendor chose to have pre-installed. The P5S has:1. Several MP3 players (PowerAMP, AIMP, APlayer and Apple Music)2. Several streaming apps (Pandora, Amazon Music, Tidal, Deezer, Spotify and iHeartRadio)3. Several eBook apps (Kobo books, Moon+ Reader and Kindle)4. Several podcast type apps (Audible, Podcasts Tracker and TikTok lite)5. Several utilities (Calendar, Clock, Calculator, Photo Gallery, Amazon Shopping, Oxford dictionary)6. Specialty apps (Sound Recorder and FM Radio)7. Other apps (Settings, File Manager, eBrowser, MX Pro Player, MiniShare File Sharing)I tried out the Poweramp, AIMP and APlayer MP3 players and all have onboard equalizers, allow for creating unlimited play lists and all offer satisfactory MP3/song playing experience.The FM Radio app necessitates the use of a wired headphone or it will not work. I found that the P5S was able to lock into more FM local stations than the M4 Pro. The audio received from the included wired headphones from both players was substandard.Both Players had a built-in internet browser (eBrowser). Both the P5S and M4 Pro allow for YouTube watching however only the P5S allows for file downloading.Now comes to my biggest PRO when using the P5S: it’s the only MP3 player I’ve ever tested that allows the user to not only upgrade the current apps installed but allows for download and installing of additional apps. It should be noted that P5S does not come preinstalled with any official app store (like Google Play or Amazon AppStore). Because of this you will need to use other "unofficially" sources to obtain the app install file (called an "APK"). Popular sites for APK install include sites like APKPure or APKMirror. These sites may not include the official APK for the app you are interested in so caution should be given when using these sites as the apps may include flaws and/or security issues. Unless you know the app to be authentic I would not add any user/passwords to loaded apps that include your payment information. The best place to receive apps when official app stores are not available is from the official developers site if possible. Because PESCU did not obtain Google Play or Amazon licenses for including an official app store I deducted one star from my review. They also didn't provide an easy way for the user to update their apps.Because of this, the first app I downloaded and installed was the APKPure APK (which can be found if you Google it) which is an Appstore that provides access to plenty of other apps. More than likely the vendor used a similar type of appstore to load the existing apps on the player. As soon as I installed APKPure onto the player I noticed that 13 apps were listed as being out of date and it allowed me to update each which was great to see. Next, I tried downloading a new launcher. My favorite launcher is Nova Launcher but it is incompatible with this player so I tried various other popular launchers including AIO Launcher, Niagara Launcher, Lawnchair and Total Launcher (all of which worked). It was great to be able to customize the screen similar to using an Android type phone. Next I downloaded some hardware testers such as Device Info, Geekbench 5, Wifi Analyzer and Speed test. I also downloaded a better browser (Chrome; which worked but constantly included notifications that I didn't have the Google Play store app installed), some video streaming apps (YouTube Vanced and Netflix) and even a couple of games (Hill Climber and some card game apps). Some apps on APKPure will work, some will not so you’ll just have to test them out. All the apps I listed previously did work.This is a far cry from the M4 Pro which although has similar apps installed initially, has no way to update them if they are out of date or to add new ones. Because both of these players come preinstalled with apps that rely on cloud interaction, sooner or later they are going to become so out of date that they will no longer work on the M4 Pro. The ability to both upgrade and install new third party apps in the P5S is a real game changer when comparing the two devices.ConclusionIn conclusion, I was pleasantly pleased with the P5S and feel that it’s hardware specs and ability to upgrade and install apps sets it leaps and bounds above the M4 Pro. They are both listed on Amazon for similar cost so I see no reason to choose the M4 Pro over the P5S.If I had any issues with the P5S it is the following (and these are minor):- Screen size too big for use as a portable MP3 Player. The P5S is more of a media player than a MP3 Player. At 5” you can comfortably watch videos and play games on it and even browse the internet. For me though, 4” is the “goldilocks” of MP3 player size when it comes to these Android OS MP3 Players- Durability concerns. Because the back of the unit is encased in glass, I would feel very uneasy with dropping the P5S (or the M4 Pro) and wished they offered more durability (such as completely encasing the phone in metal or providing a protective case).- Old BT chip used. The newest BT chip is 5.2 so both of these using are using older BT technology. It would have been nice to see the latest and greatest BT chip installed into the P5S. Player having a better built-in BT chip will allow for better HD audio file streaming and faster pairing, longer ranges and the ability to pair multiple devices at once.The only other option that I think competes with the P5S is to look into resurrecting an older smaller/mini phone to serve as a standalone MP3 Player (such as the Samsung mini S5). The mini S5 offers many advantages over any of these MP3 players (fully customizable Android OS experience, bigger battery, more storage, better CPU, water resistant, more sensors (GPS, accelerometer, etc), water resistance). The mini S5 is similar in size (4.5” vs. 5.0”) and is made by a reputable manufacturer. If interested you can still purchase used mini S5s in good quality for around $50 from various online auction sites. Moreover, the battery is very easy to access and is replaceable if necessary/desired. The mini S5 also has protection cases available and is probably more durable than any of these MP3 Players. If you’re techy you can even update the mini S5 to Android 9.0 and get a complete Android experience compared to these players which have heavily modified “lite” versions of the Android OS.
