“This is my first review for a product so I maybe lacking details in some areas or using the wrong terms. Forgive me for that. I did buy these in Japan at a department store called Joshin so I don't have the technical details but you can find them here http://www.audio-technica.co.jp/atj/show_model.php?modelId=2305. In terms of USD I think I payed roughly $65 and they were definitely worth...” --purpledrank
“Design: The IM-04 is quiet bulky, but it is rounded off in the inner side, and with the short nozzles I have found no fitting issues whatsoever. The body is shinny with pitch black color, and a gold logo of Audio Technica. The shells are made of hard plastic, and of what kind of quality and durability is up to guesses, but I will have to go with "Japan made" and say...” --Whitigir

Silly me because I just found out how to add new item for review, discussion purpose. I bought the CKB50 through Aliexpress for just 26USD, free shipping.

“I recently bought these as an upgrade to my Head Direct RE0's. The RE0's are outstanding value for money, and there is not many headphones that can beat it ... until I got my hands on the CK100's. The CK100 packaging box is nice - very simple, and does the job more than adequately. What I noticed on it, which I've not seen in many other headphone boxes is that it lists the product code for...” --s0126471

“ These are most likely the best IEM's you will ever find for trance, let me explain, firstly it is as if they are fine-tuned and sonically crafted for Trance and similiar genres, all the vices you heard in these IEM's in other genres suddenly become virtues and they simply come alive and you are swept away. Secondly, there is something about the sound signature in these IEM's that is trance...” --kiteki
“ Prior to purchasing these, my primary concern is to have a proper alternative for my ESW9 which have better isolation to be used for listening to my ballad tunes on the road. While I don't have any issues with louder tracks, with more subtle ones, my ESW9 aren't up to the task, and so my search began. Actually, I'm not really keen on the idea of using an IEM since they irritate my ears...” --lotusbloom
“ Anyone looking for a highly balanced, highly detailed sound look no further. The CK90 pro is a great IEM and is unfortunate it doesn't receive as much recognition as it should. The best part of it's smooth sound, is it's lush mids; on par with great mid names such as Sennheiser and Shure. The bass is good for an armature driver. It has great presence and impact, but it lacks the...” --bisayaboi
