Audio-Technica ATH-CK2000Ti in-ear headphones

Audio-Technica's flagship earbuds Why does Audio-Technica's name ring out among both musicians and high-end headphone fans? They're committed to delivering richly detailed sound across an incredibly wide frequency range. With their flagship in-ear headphones, the ATH-CK2000Ti, they've come up with a completely new driver design to deliver the results. Uniquely designed "dual phase" driver system Audio-Technica designed the earbuds to sound both revealing and musical - with minimal distortion. And they've done it with an in-ear driver design that I've never come across. Inside each earbud, there are two drivers positioned to face each other. One is 9.8mm and the other is 8.8mm. The mismatched size helps improve high-frequency response, and they are wired out of phase for controlled bass reponse. A strong titanium housing helps further lower resonance. A proper fit for sound Here's something I've learned from listening to many, many in-ear headphones: their sound is only as good as their fit. Audio-Technica includes 7 pairs of ear tips to ensure a secure, comfortable seal. There are four sizes of silicone tips, built to properly direct the drivers. And - my personal favorite - three sizes of foam ear tips. These super-soft tips expand and conform to your ears, and help block out noise. Several ways to connect The ATH-CK200Ti headphones include two cables, one with 4.4mm balanced headphone plug. Sony developed this new industry standard connection for balanced headphone operation, and I've seen more and more companies adopt it. This connection promises to cut down on signal noise and distortion, and you'll find it on several Sony high-res music players , the Sony's TA-ZH1ES headphone amp , and the Sennheiser HDV 820 headphone amp . For a more traditional headphone connection, Audio-Technica includes another cable with an unbalanced 3.5mm mini plug.
