More listening time = these have got to be the best sounding IEMs for under $100 that I've heard...by far!!
My friend in the next cubicle has the TF10...the CKM500 can't quite compete with the UEs. The CKM500 is way more comfortable though. Also, the CKM500 is less than half the price, yet you don’t get half the sound quality of the TF10.
