    I just bought these Devils in red color. Was first going for the lower version of this headphone, but thanx to the sales guy he talked me into these. When it comes to music quality i want it to be fabulous. Being a musician my self i do have a little understanding of what the quality should be. I can say that in this price these are the best. The balance of High,Mid,Low (Treble, Mid, Bass) is quite good. The earphones as the name says "Solid Bass" surely has a great bass effect but even if you want to listen to classical music you can easily adjust it from equalizers. The only thing i forgot to look into was the cable noise. i.e. when you rub the cable you can here the disturbance in the earphone. But once you play the music you'll not even notice this. Noise cancellation is great automatically,but seriously if you are looking for noise cancellation device in "Inner Ear Headphones" then i don't know what to say. Still waiting for it to "burn-in". Lets see how this turns out.


    I love them but...


    These are the best sounding buds i have heard including some $200+ competitors. They are very comfortable and efficient as well as the excellent sound quality. Noise isolation is good and even better when foam tips are added. Now for the "but"...The impedence is 14 ohms which is pretty low for headphones. Many (especially cheaper) devices don't like the lower impedence and make strange sounds or run hot.

  • Q & A

    is ATH-CKS77BK compatible with iphone 4?


    Yes. Please keep in mind they are just headphones (no microphone). The closest headphone product that has a microphone is the ATH-CKS55iBK.


    Comparision with ATH-CKS55BK Hi, as i look to the specs of these two ear-buds (ATH-CKS55BK and ATH-CKS77BK), i can't really find a major differences between them. I really wanna know that what make ATH-CKS77BK almost twice more expensive than the younger brother? Thanks a lot...


    Thank you for your inquiry. They are similar, although their frequency responses ar different.


    To be quick and simple, every thing is the same, its just the quality is better that 55 so the experience is also better. If you go in specs. you can fined higher Freq. range, low impedance (i.e. low disturbance), higher sensitivity (though only 1 point but it is there) which adds up to the experience. To be short and simple if you want every details to be picked by you ear within the price range go for 77, or else if using casually go for 55. I hope i replied on time.
