Hisoundaudio ROCOO-A

This review is made with beta firmware, I will update the review accordingly when new firmwares are released.

Upgradeable firmware
Text and lyrics reader

External hard drive, drag and drop

Included accessories:
USB Cable
High quality IEM’s


Build quality and hardware:
The ROCOO is made of high quality plastic and what seems to be a metal frame, it feels very well put together. The screen is built in behind of the face of the player which makes it look very exclusive, and it works very well too. On the face of the ROCOO there is a rocker pad, with prev/next track and +/- volume as well as scrolling the menus. To the right of the rocker pad there are two discreet rocker buttons, menu/select and play/pause combined on/off. At the top of the player there you will find a microphone and a rocker button for recording and A-B repeat. On the right side, there is the mini USB port and headphone out, at the bottom is the on/off slider button and a reset hole, and on the left hand side is a micro SDHC slot. On the top left of the face, there is a blue blinking led, that indicates the player is on. A little trick to turn the player on/off, put the bottom slider to on or off and press lower discreet rocker, play/pause for 2 seconds.

Audio:
The included earphones are much better than the bundled ones on your average player, the difference is like night and day. But to really test the audio qualities of the ROCOO I have used a wide array of IEM’s (ATH ck10, Senn IE8, Hippo Shroom, FA Eterna, to name a few) and a full sized can (Philips SBC HP1000) as well. First off I can note that there was a very slight hiss from the beginning, but it seems to have vanished after a few hours of use.
The ROCOO sports a Class A amp, with an incredible power for such a small device, it can easily drive the rather large and demanding HP1000’s. The sound signature is natural/neutral, bass is deep and plentiful, without being too bassy or overpowering and what I can hear it does not suffer from any roll-off. Mids are lively and detailed, I can hear details in music that I could not hear with my Cowon D2 or Sansa Clip. Highs are clear and sparkly, without sounding harsh in any way, and again without noticeable roll-off. The soundstage is wider than both the D2 and Clip, and what more is that it is very nicely layered and instrument separation is excellent.
As I have found the ROCOO sounds especially good with warmer sounding IEM’s, Klipsch S4, Hippo Shroom, FA Eterna and Sennheiser IE8 are very good in pair with this little power house. It should also be noted that the supplied IEM’s sound very good.
There are EQ and DSP options for those who wish to use them, but to be honest, the ROCOO sounds so good that most users should not need to tinker with any settings.

Extras:
There is a text/lyrics viewer and a voice recorder built in, which can come handy at times.

Conclusion:
The Hisoundaudio ROCOO offers a exceptional sound quality and stunning design. With the included IEM’s and for the price of $99, I cannot think of another player with such a great sound out of the box.
Highly recommended !!!

Nice review, thanks! Where did you buy the player (or is it a review sample)?
I'd also be interested if it will resume from the last played track and stay within the last played folder - one basic function the AMP3 didn't get right.

It is a review sample, which is still on the beta FW, so it may get even better.

The ROCOO saves the last folder and song, and resumes from there when turned on again.

How long does it last on a charge? Just curious.

I have not had time to do a full battery drain test, but the stated 10h would seem very reasonable. Having a class A amp does take its toll, but it's really worth it.

Hi

Just one Question: Is this player a improved version of the Cube C30?
post #7 of 147
How much memory does it have?

Dang, can't believe I missed the memory!!! It has 4GB.

As for being linked to the C30, I can't say for sure, but they look very much alike, difference being BBE and class A amp.

C30 has a power amp, although it did not advertise it as Class A. C30 was supposedly designed in Korea. I suspect it could be Class A amp + BBE. So, I suggest to wait a month of two, someone will put up "autopsy" photos for sure.

"Autopsy" would be cool. It is interesting how the soldering work and what the other chips are. However I found through surfing the internet that the amp is the: MAX9722. Is this a class A amp?

What are the differences between this and the AMP3?
The lack of roll-off already makes it kind of attractive..
post #12 of 147
how do you know there is no roll off? People said the same thing of the AMP3, but it rolls off. It isn't a sound thing like, 'well the bass sounds good' - that doesn't mean there isn't roll off. Some of the bassiest machines are rolled off. Their mid bass comes through unattended and sound boomy - that does not mean not rolled off.

easy to test with a 40hz square wave.

Any comparison with the Fuze? Not like I need more gear to tempt me.

Are there any pictures of this thing's OLED screen in use? does it seriously only have 2 lines of text?

It will be a pain to search for songs if it only has 2 lines of text
