Crave: Anyone familiar with Sennheiser’s flagship headphones, the HD 650s, will know they’re a truly stunning pair of open-back cans for reference and home listening. And we love them with the flaming passion of a thousand burning nymphomaniacs.
But the vixen of the open-back headphone world has some competition: AKG’s K 701–a pair of similarly priced open-back reference-class headphones.
After about 100 hours of burn-in time we’re happy to discuss some first impressions of these moist-making headphones. Firstly, design. The 701s are extremely comfortable, with a slightly less tight fit to the head compared to the Sennheiser alternative. And the well-padded earcups are encased in cloth, meaning you’re less prone to sweaty ears.
Inside are decent specs too: a frequency response of 10Hz-39kHz, impedance of 62 ohms, a rated sensitivity of 105dB/mW, and a maximum power input of 200mW. The foil diaphragm is dual-layered, hopefully deliverying a more impressive transient response than usual.
