BENJIE K9 8G APE/FLAC/WAV High Sound Quality Entry-level Lossless Music Player

1000+ Head-Fier
Pros: Built in loudspeaker, colour screen
Cons: Some distortion and bacground noise between tracks
I have had the opportunity to review a few inexpensive MP3 players recently and have generally been quite impressed with many of them as they clearly appear to put sound quality before pretty much anything else - and also kept their costs down as a result.  Whilst there’s nothing wrong with the build quality of these units, they certainly don’t have the same build quality and attention to fine detail that you find on Apple and perhaps Sony music players. In all fairness though these players cost many times - many many times more and basically offer pretty much the same basic function.
 
One player which really impressed me was the tiny Benjie S5. The sound quality produced from this tiny player is truly remarkable and I was very interested to see if their K9 model could match - or even beat it.

Externals
 
Externally the K9 is larger than the S5 but not much heavier. One of the differences you will notice straight away is the use of a colour LCD screen on the K9. With a claimed battery life of up to 80 hours, this is quite an achievement.  At first glance you could possibly mistake the player for one of the older Apple Ipod Nano players but rather than a thumbwheel, the K9 uses a more conventional diamond configuration for the buttons - rather like those found on some of the Sony MP3 players. The back of the unit is steel and the front feels like plastic. The colour screen is bright and has a reasonable resolution. There is an Micro SDCard Slot on one side whilst the other side and top of the unit have no buttons at all. The bottom of the unit has the headphone socket, Micro USB socket and power switch. Another thing which sets this player apart from the others is the inclusion of a loudspeaker which can go surprisingly loud.
 
Controls and Interface
 
The controls are a little strange. This is because the K9 tried to put its functions into five basic controls - up/down/left/right/OK. The only other control is the power switch. As a result, the controls have multi functions depending on how long you hold the button down for. I personally don’t like this approach but one advantage the K9 does offer is the ability to use the player in the dark. The S5’s touch interface is quite difficult to navigate in pitch black darkness because the controls are not backlit,
 
I found the buttons tended to rattle a little which was a bit of a shame but it doesn’t effect the basic functionality at all. Whilst the screen is bright and clear - even offering a reasonable resolution, the text size is too big and as a result, the screen can only show a limited amount of information. This is a shame because the screen really is quite clear and bright and could almost certainly be exploited more than it is here.

The speaker is activated by simply removing the headphones. Whilst it’s sound quality is rather dire, it does go surprisingly loud and, given its limitations and the price of the unit, can be kinda forgiven. In all fairness, I strongly suspect if Sony or Apple produced an MP3 player this size with a built-in loudspeaker, it wouldn’t really sound very much better.

The K9 has a reasonably powerful headphone amplifier and can certainly go loud enough for most portable headphones. I could detect a continuous low level amount of background static when using sensitive IEM’s - although this is not as obvious when using larger headphones.
 
Navigating through the interface does take some getting used to but it didn’t take too long for me to adapt. I found the sound quality to be fairly neutral but also a little lacklustre when compared to the S5. Basic playback modes are offered and the unit supports the creation of playlists - although in all fairness I didn’t really play with this feature all that much.

EQ is available and this includes user-defined settings which is a welcome feature. Activating EQ results in a drop in volume and I tend to usually leave the setting off. However, it’s always nice to have the option.
 
All in all this is a reasonable player but is not as good as their cheaper model when it comes to sound quality. However the built in speaker does make it stand apart from other Mp3 players out there and this allows me to offer a guarded recommendation.

Pros: Sound quality for the price; Build quality; Solid battery and firmware
Cons: Awful UI and Navigation; No dedicated volume buttons; Terrible volume control (with more sensitive earphones)
REVIEW: Benjie K9
 
 
Specifications:
 
Screen: 1.8”OLED
Case: Zinc alloy
Size: 94*38*9mm
Weight: 79.2g
Capacity: built-in 8GB flash memory, up to 32GB SD card external storage
 
 
Price: $25, from Penonaudio.
 
Accessories:
 
  1. Micro USB to USB Cable
  2. Earphones
 
The earphones are very hard to drive, even for the K9 itself it's needed to reach about half of the full volume (~15/31) steps
 
 
Build & Design:
 
Build quality is quite good for the low price, and much more solid than the more expensive popular budget options like Sandisk Clip and iPod. The player is very compact, made of sturdy metal alloy body for back and sides, and transparent plastic front panel and plastic buttons. While compact and very pocket friendly, it also has some weight due its metal material. The OLED 1.8" screen is quite nice and quality is very decent.
The control/navigation buttons are all placed at the front panel. At the bottom there're the ON/OFF switch and 3.5mm output plug, and at the back part, the built-in speaker.
 
 
UI, Navigation, Firmware:
 
I won't cover all the features and functions of the K9 player, just will mention some characteristics. After all, it's affordable enough to give it a try and rather intuitive to figure out after some use anyway. There's always the included manual for more details.
Firmware seems solid and stable enough, and I haven't found any kind of bugs or crashes. But unfortunately, the UI and navigation are the worst part of this little device. It's very illogical and so incoherent. Just to mention some things:
 
  1. When switching on it goes back to the start of the last session, including even the volume level used last time.
  2. Play/pause also works as on/off when held a few seconds (if switch is On)
  3. Back (left) and Fwd (right) are used to navigate up and down through menus.
  4. There are no dedicated volume buttons. V (vol) is to be pressed for a few seconds to access the volume control screen and adjust with left and right buttons.
  5. No Home option. Needs to use V button to go back to the main screen.
  6. Folder skip; doesn't play files of a selected folder alone, once it reaches the last track it continues to the next folder, and after playing the last track it starts the whole list again (even when Repeat option is off).
  7. Files and folders are not alphabetically ordered, but displayed in the order they were added.
  8. Switching from internal storage to micro-sd card and vice-versa stops the whole playback.
 
The only good thing I found on the K9 is that it can delete a whole folder content, but even that is just half good, as the folder is still displayed despite being empty.
The K9 also works as an image viewer and its quality is actually not that bad. Images can be displayed without stopping the music playback. Same goes for the text (.txt format) reader. The manual also mentions Video playback, but only in '.amv' format which I couldn't test yet. K9 has also some extra features are FM Radio and Voice recording.
 
 
 
PC connection and file transferring:
 
When connecting the K9 to a Windows computer, the device is turned on regardless the switch position. It's possible to choose between 'Charge & Transfer' or 'Charge & Play'. With the first option the device is automatically recognized by the system and listed as "M27", while the second option is only to charge and keep using the player normally.
 
 
Battery, Hiss/Noise:
 
Not sure about the rated battery specs, manual states ~12hrs, and the official site ~20. From personal use, the 20 hrs seems to very accurate and the battery behavior is solid enough and doesn't suddenly drain.
Hiss and background noise were not noticed even with most sensitive CIEM sets.
 
 
Power, Volume:
 
The K9 can get quite loud and powerful for its small design and small budget price. It can drive harder sets such as the Yuin PK1, VE Asura (1 and 2) earbuds with their 150ohm impedance without trouble, and doesn't show any kind of distortion, and even the Zen 2.0 can be driven to a decent level and still not passing the half 30 volume sets.
The volume control is just awful and not well suited for sensitive sets. The volume jump from step to step is very strong; the sound is either too low or too loud. Personally, I find this as a deal breaker despite the very low price. Using an amplifier fixes this issue but makes it a bit less portable.
 
 
Sound, EQ & Amplification:
 
The K9 sound presentation is towards the warm and rich side without a strong roll-off at either end. It does still add certain coloration to the sound, trading some transparency and detail for more fun, musicality and deeper tone and richer texture, but keeps a good overall balance from lows to highs.
 
With a fairly strong low end response, bass is more impactful and better bodied, but can be slightly boomy with warmer sets, though not more aggressive than it should. On the other hand, leaner, brighter or analytical head/earphones can find a good match with the K9, achieving a more substantial lower end without losing their strong detail. The extra warmth also contributes for a more natural texture and decay, though just a tad slower in speed.
 
While the bass is not really dominating, the midrange is not as forward as the low end. It is still fuller, not too sweet but not too dry, which works well with any kind of earphone. Yet, with more v-shaped sets, the mids seem to be slightly more distant than what they already are, though it can be quickly fixed with the simple equalizer of the device. Vocals can sound more dry and less engaging, but instruments keep a fairly good level of separation.
 
Treble is offered in a similar fashion as the midrange, well balanced and fairly extended with a slight roll-off at the upper-end and more laid back nature. A bit more presence and sparkle could have been nicer, but at least the more musical presentation of the K9 is fatigue free even with more energetic earphones and tracks.
Micro detail is not the strength of this small player but nothing to complain for the small price. Soundstage is about average in width or height, but the K9 adds more depth to the sound. Imaging is decent but not too accurate, though it still compares really well to other popular choices.
 
The K9 easily beats the Clip+ in terms of coherence, naturality and almost every other aspect. The Zip and iShuffle also sound smaller next to the K9, though I found the Zip to be more balanced. Lastly, the K9 and Clip Sport are fairly equally matched in overall sound, but with different flavors; Sport is leaner, brighter and more detailed, while the K9 warmer and more musical and bigger sounding.
 
 
 
EQ:
 
The K9 lists a few equalization presets options and a simple custom 5-band option. Apart from the 'Rock' and 'Jazz', the rest of the presets are not worth mentioning. On the other hand, the Custom 5-band works surprising well (far from the terrible custom EQ option on the Sansa devices). While not as accurate as the HM700 one, it still helps to personalize the sound quite nicely.
 
 
 
Amplification:
 
The K9 is quite a powerful device to need an amplifier for pure volume matters, but it does benefit quite well from extra amplification to reach a higher sound level. Improvements in dynamics, stage dimensions and detail are easily noticed, although the K9 strong sense of warmth is still perceived through the extra device affecting the overall transparency unlike the Clip Sport. Using an amplifier also fixes the K9 volume control issue.
 
 
 
 
All-in-all...
Among the so many and random low priced Chinese players the Benjie K9 small player is surprisingly a good contender. Having more expensive and dedicated devices, I was planning to use it mainly as a backup device, but then, the sound quality and presentation for its low budget price proved to be much better than expected. The outer build quality is quite good as well, and also has a solid battery performance and firmware. Even though, there're some flaws. While it's possible to get used to the interface and illogical navigation, the biggest issue is the volume control that make it useless with many IEMs to be used on the go. For those who can overlook or do not care about these issues, then the Benjie K9 should be great buy.

Package and accessories:
The Benjie K9 comes in a very compact box that despite its low cost has a much more premium appearance to it.
Included in the box is a USB-USB micro cable for charging and transferring media, an instruction booklet, a complimentary pair of earbuds and the player itself.
The provided earbuds actually sound quite good but they’re really hard to drive. The cable feels strong and there are really good strain reliefs on the Y-Splitter and plug.

Build:
I was surprised by the weight of this DAP when I took it out of the box. For such a small and inexpensive player, it feels very solid in the hand. There are no rattles or loose buttons on the device anywhere and my immediate impression was very positive.
 
The casing is cut from a single piece of zinc alloy that feels solid and reassuring and has nice, smoothed edges. On the front is a plastic cover from top to bottom which also acts as the windows for the screen. Below the screen is the control wheel for navigation and adjustments and in the middle of the wheel is the play/pause/OK button. On the right side is the Micro SD card slot. On the bottom is the on/off switch, micro USB charging port and 3.5mm audio jack. On the back you’ll find the Benjie logo, along with the model number and the built-in speaker.

Power Output:
I wasn’t able to find specific details for power output but the K9 packs a punch. Admittedly I haven’t tried it with any high impedance gear – the highest I’ve tested is my Kingston HyperX Cloud (Takstar Pro 80) which is rated at 60 Ohms per unit. For all the various IEMs I’ve tested there’s plenty of power and then some.
 
Sound:
I’m not going to talk too much about the sound here. After all we’re talking about a $20-25 product (depending on where you purchase). I will say that to my ears it sounds as good as the XDuoo X2 which is around double the price.
 
Conclusion:
Look at those features. Just look at them! I won’t ever use a lot of them (speaker, e-book reader, voice recorder etc.) but they’re there if the need ever arises.
 
The only thing I don’t like about this DAP is the lack of dedicated Volume buttons. I also wish that pressing Up and Down would correspond with navigation in the UI, rather than Left and Right to scroll through lists and menus. The volume buttons I will always miss but the UI was second nature by the second day of use.
 
It feels good in your hand. It feels robust and solid. There are no rattles or loose parts. The screen is clear and visible even in direct sunlight. It sounds good. Custom EQ. 12+ hours playback time and fast charging… You get the idea. All of this for the same price as a budget pair of IEMs or a couple of junk food lunches. If you need a portable DAP and don’t need high end features like a line out or Bluetooth buy one of these. Buy one now

@farhat I'm not sure what you mean. The volume limit is the maximum volume you can set it to right? I have it set to maximum (31) and usually have it at about 8-14 depending on which IEM and album I'm listening to.

@crabdog, bro when you go to the volume display, you can set it to whatever level you like, let's say I adjust to 24. Then I change back to 31, but when I exit the volume display (the display which shows the wheel from 1-31), the volume is locked to 24. The lower I adjust the volume, the lower the volume limit "locked" will be. Also, I put on 31 yet it ts not loud enough. I wonder how can you use 8-14 and that's enough for you. I must have a faulty player.

I have the Benjie K9 and I love this little player.. do you have any idea how to make the player load the file tag information for songs in the SD card?
I have to use the 'folder view' to find my music and its a pain sometimes when the filename is abnoxious..
