Sound Quality

The most important factor when it comes to equipment like IEM's and headphones.
I am very supprised of the sound quality for its price($89)
. Has a broad sound stage but has a lot of punch to it as well.
You cant go wrong for this price. But I would say that these IEM's are for bassheads. (which I am)
 

Bass Quality & Impact

The quality and clarity of the bass is not that high, but I can say that it has a lot of impact. Sounds like you have a subwoofer in your ears. So I would say that these are for fun listening rather than detailed listening. I assume the venting is causing this bass to boom but is also lowering that clarity at the same time.

Mids

The mids are nothing special because it is more of a bass emphasized IEM. (which goes the same for most bass heavy IEMS) But there is enough clarity and quantity for me.

Highs

The highs are preatty decent. Has a decent amount of quality and shines.

Soundstage

Sound stage is preatty broad for an IEM and a IEM in its price range. Its probably because it is vented on the bottom of the IEM.

Build Quality

Not sure how much these IEM will hold up because I have only used it for a few weeks, but it seems to be ok so far. But since it is lite, I have a feeling that it may break if you use it too roughly.

Leakage

This is an important factor in Japan. Because people tend to start fights if your sound is leaking on the train or some sort of local transportation. This is what sucks about Japan, so I don't like IEMS that leak a lot, and the POPO IEMs tend to leak because it is vented. Due to the vent, the isolation is not that good as well, even with Comply foam tips

Accesories

It comes with a lot of eartips which is preatty standard for any IEM now. So Its OK. It also comes with a shirt clip. But it would of been great if they included a case. It says "option" on the package so you might be able to get one if you ask for it.

Conclusion & discount notice

These IEMs are great for its price which is $89. If your a bass head and like to have an IEM with a broad soundstage. this is for you.

 
Hi Head-Fiers!
I am pretty new to this community but have been making unboxing and review videos here on my YouTube Channel:
TechSpotJapan Youtube 
 
I recently purchased a RoCoo-P and would like to use this space to post a review.
 
First, here are the basic scores that I give for each category:
 
Build Quality     : 8/10
Sound Quality   : 9/10
Design             : 8/10
UI                    : 5/10
--------------------------------
Overall             : 8/10

First Impressions

Out of the box, the sound that the RoCoo-P felt un-natural to me. It felt like the sound was tampered with in some way, such as an EQ.
So I checked the EQ settings, but it was set to nature, which I assume is the flat setting of this device. And since this was my first Non-iPod experience, the UI felt old.
These impressions has changed after using the device for a while. That is why I have decided to write up the review now.
 

Build Quality - 8/10

The devices main body is made out of metal which I assume is aluminum. It feels and is sturdy. All the ports also feel sturdy and feels like it will never break.
Now your probably thinking, "Why did you give a 8/10 instead of a 10/10?"
The -2 went to the front and back of the device.
It is very shiny and attractive, but is also a finger print magnet, and easily scratched.
I use my devices as if it was a baby. But it got scratched when putting it in the case I carry the RoCoo-P. It slightly touched the zipper of the case which created some scratches on the back.
I was pretty sad when I found this.
 

Sound Quality - 9/10

In my initial impressions I told you that it sounded un-natural, but my impressions has changed after using this device for a while. Did it burn in? or did my ears(brains) burn in? I am not sure, but what I can say is I am very happy with the sound now.
Compared the the iPod video(5g) that I own, it has a lot of energy and punch. But is also quiet when it needs to be.

Bass

The bass on this device is great. Lots of clarity and impact. Which might be one of the reasons the sound is energetic.

Mids

The Mids are amazing! Male/Female vocals are not getting muddled by the lows, and has lost of clarity. I hear sound that I have never heard on other devices.

Highs

I think I'm saying great or amazing for the Bass and Mids. But this goes the same for the Highs as well. The Highs sparkle but is not too harsh. They do not hurt your ears and are easy to listen to. This is also another aspect of making the sound exciting.

Sound stage

For a portable device, I would say that the sound stage is pretty broad. Of course it depends on the IEM's or Cans you use, but even if you listen to the same song on the iPod, the iPod sounds like its just ringing around your ear, where the RoCoo-P gives you an more spicy sound. The soundstage is broad but does not ruin the sound separation. Thanks the the broad sound stage and good sound separation, it sounds like your listening to the song in a live house or stage. 
 

Design - 8/10

This devices looks sexy. If you want the same sound quality with a iPod/iPhone, you basically need to strap a decent amp on it, and compared the that, it looks much sleeker and sexier.
This is kinda about the build quality, but the front and back were not that great, leaving design an 8.
 

UI - 5/10

This is probably one of this things I hate about the UI. I would say, it sucks.
Maybe because the I am used to iPods, but even after using the RoCoo for a while, I still think that there are many things that can be fixed. The UI is quite familiar with the SanDisk Sansa clip but no return button the the RoCoo, which confused me.

Conclusion

If you are a serious listener, or want more energy to your music. Or if you have an hi impedance headphone/IEM, I would say that this device is a buy! This devices sound amazing, and constantly keeps my head banging. I assume any device will sound better that an iPhone/iPod, but I personally think it sound better that an iPod amped, which is clunky compared to the small device.
