K701 Headphones with HeadRock Headphone Amplifier

The AKG K701 and Rockville HeadRock pair a premium open-back reference headphone with a portable headphone amplifier, closing a common gap for open-back headphones: they generally need more driving power than a phone or a laptop's headphone jack can reliably supply. The K701's flat-wire driver technology places each instrument precisely in the sound stage, with a 10 Hz to 39,800 Hz frequency response and 105 dB SPL/V sensitivity built for critical mixing and mastering work. The HeadRock covers the power gap with a rechargeable 800mAh battery driving headphones from 16 to 300 ohms, a high/low gain switch to match different sources, and 5 to 8 hours of runtime per charge from its included micro USB cable. Together, the bundle lets you get consistent, accurate output from the K701 regardless of whether the source is a full studio interface or a laptop with a weak headphone output. Engineers and serious listeners who want the K701's imaging without needing to separately shop for and match an amplifier get both halves of that setup in one purchase.
