Placing the 'phones over the old Uncle Ned, we felt a similar level of comfort to the ATH-W1000s, which got a excellent rating in our review last week. They're snug without too much tightness.
Inside are decent specifications: a 53mm neodymium-backed driver responding to frequencies between 5Hz-40kHz, an impedance of 40ohms, sensitivity of 101dB and an excellent maximum power input of 2,000mW.
Our mild surprise began when we started listening to the A900s. Although they produce the bright voice we've heard throughout the entire high-end Audio Technica family, this brightness adds a certain colouration to music, making them slightly less a headphone for home studio reference and more for home listening.
If you're listening to vocal music, you're likely to be very pleased as the A900s excel at reproducing vocals, particularly those of female singers. Ingrid Michaelson's voice on her track Let Go was so vibrant and pleasant, it reminded us of how wonderful a vocalist she is, with all the breathy undertones of her airy voice conveyed with great detail.
What sounded less impressive was hard rock and metal, which lacked the meaty, smash-you- in-the-face-with-a-sledgehammer power and bass it needs; it sounded too harsh, too brittle.
Expect our full review very soon. If you love your Sarah Brightman, Alison Krauss and Sarah Bettens, you're going to want to check it out. Click 'next photo' for more delicious details. -Nate Lanxon
