ATH-CKR9 | ATH-CKR10

What’s new in this series is a Dual Phase Push-Pull technology developed by Audio-Technica’s Japanese engineers. Originally developed for audiophile speakers, the technology has been adapted for earphones by mounting two 13mm dynamic driver units facing each other. The two units move simultaneously, but in opposite directions, thus increasing their efficiency.

The ATH-CKR10 has two 13mm drivers.

The ATH-CKR10 and ATH-CKR9 both feature dual phase push pull drivers, with bass acoustic resistors for improved low-frequency control. The ATH-CKR10 has a frequency range of 5 to 40,000Hz, and has a low impedance of just 12Ω, with titanium housings to reduce unwanted vibration.Meanwhile, the ATH-CKR9 has a frequency range of 5 to 35,000Hz, also with an impedance of 12Ω. This set uses aluminum housings to reduce unwanted resonance for a crisp mid-high audio range.

The ATH-CKR10 and ATH-CKR9 retailers price are S$338 and S$248.
