“ CK7 earphone is a nice detailed ear piece with titanium housing which makes it very durable. For me, although i am not using it very often this works the same as it used to be the first day i bought it. They require burn in time at least 100 hours and you can definitely tell the difference in the bass section and the mids. Comfort: i would recommend to be worn...” --FarCry
“ 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
“If you are looking for a bass monster, you should not overlook this earphone. The ''monster bass'' you are going to get from this earphone will not even be delivered by some expensive “headphones’’.

The bass quantity is just amazing without sacrificing the mids and the...” --Whataudiophile

But unfortunately it is not my best IEM since I bought JVC FXT90 about 1 month ago. Overall FXT90 sound quality is slightly better than IM50. Both IM50 and FXT90 has fairly balanced sound with IM50 has...” --AzimAkbar
“ ATH-CKS90 is Dynamic earphones. The sound quality is high. Recommend to people who like bass. [Sound] ATH-CK10 is clean mid - treble. But bass is lacking. Purchased in order to compensate for this frustration. To enhance the midrange and high frequencies CK10. The fully equipped with bass from the midrange is a feeling...” --T.IIZUKA
“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
