CKS77? And a CKN70? Both completely different. The CKS77 is a second generation solid bass earphone. Similar tuning to your WS99 but not nearly as refined. I would skip those and go directly to the CKS99 because these will cost about the same but is a 3rd generation Solid Bass earphone. New tech involved in the housing using dual air chambers that gets these things even closer to the WS99 in performance. The earphone equivalent to the WS99 is the CKS1000. Flagship model..
The CKN70 is the subject of what we are talking about here. The mids have a similar quality to the ES700 but the highs do exhibit some of the older AT house sound. Which tames with more burn in. Far exceeds its cost in value and sound. I couldn't take them out of my ears last night..
Also on that note. I have discovered that the CKN70 the way it is tuned and their ability does not require amping or more power for them to sound their best. Almost an armature in dynamics these are more suited for listening on your cell phones and daps more than requiring any type of amplification..I have discovered last night that just using my Sony Z1060 and the CKN70 gives me a similar type sound to a well amped headphone in dynamics..Keep it simple with this one for best results me thinks.
I would pass on the CKM77. Those have a very V shape sound frequency. Very much the older AT house sound. They don't touch the mids that are on the CKN70.
Same here, i find it to sound worse when amped. LoL Straight outta my lamo ipods classic/ nano they shine like a mofo. More than enough juice to drive them from these mp3 players. Which for me is another plus for these CKN70s which makes them perfect for portable use. I went out with them clipped and it was crazy windy, but did not hear any microphonics. And they isolate really well when the music is on. These CKN70 is A++ in my book, lovin' the j-cord even the snake like nature of them don't really bug me for some reason, cuz alls you need is a good ol' clip and problem solved.
