“Some "Provenance" to the Brand Name: Ocharaku is a "tea themed" company based in Japan. Focusing on Dynamic Driver IEM's, Ocharaku pushes the envelope when it comes to breaking the negative "dynamic driver" stigma (Balanced Armatures being viewed as the superior transducers by audio snobs). Utilizing resonance chambers and other proprietary technologies, Ocharaku is pushing the...” --kevingzw
“I actually have the ES900m, which doesn't have microphone and control buttons, but the rest is the same. For $6 it's impossible to buy a pair of earphones as good as them. I really believe that the body of the earphones are metal, even if they are not, it's made of a very durable plastic. It's nothing like the entry-level Sony or Philips earphones which are made of cheap...” --mrplt
“The ES800 are the kind of IEMs you won't like how they sound out of the box: they sound thin and aggressive, with piercing mids and highs. Then you will question the design: the hideous "gold drop" on the back, the flat cable, the enormous cable splitter. The tips are not so good either.

“My experience with this one was enjoyable while it lasted. I liked the sound quality, a whole step above peasant IEMs on that price range. They're big so I had to fiddle quite a bit to get a good seal, also I suggest to wear the cable over the ear to avoid extra noise when the cable moves. People with small ears will have trouble with this ones. The cable produces noise, not very good. The...” --zareliman
“ What can I say about these? I saw a lot of people going for the Awei branded items on eBay, so I got one myself. They were surprisingly good and surprisingly bad at the same time. I will explain. Pros Housing build - For $2, an aluminum housing is quite exceptional. Accessories - While the Awei K80 only comes with one pair of tips, they are surprisingly pretty high quality. Somewhat...” --pro1137
