Impedance: 65Ω Forums. Thank you so much for this. It just doesn’t play very loud directly from a  phone and requires quite some volume for the bass to ‘snap’ into the correct level (Fletcher Munson / equal loudness contour curves) While the Sennheiser have slightly less low-bass than the AKG, they have a better-balanced treble range and are more stable on the head. Don’t think this is very detrimental to the sound. Beyond 1ms the signal drops gradually and shows the bass roll-off. Impedance As the K702 is not a high efficiency headphone this too suggests it is not designed for portable usage. voltage: 3.5V Some headphones will go as wide as 5Hz – 40,000Hz, however from 20,000Hz additional range doesn’t matter much, because we can’t hear those frequencies anyway. I sent an email to AKG asking if the design had been modified in order to make it more appealing to the larger numbers of audiophiles at the expense of the relatively small number of recording studio enthusiasts.

When a product is discontinued or no longer popular, we sell the purchased products locally in Montreal, Canada. The resonances shift in frequency when the ear-driver distance changes. Above 300Hz the distortion remains below 0.5%. The 2nd harmonic distortion is probably lower than 0.2% around 1kHz as limits of the test rig are around that level. As the foam in pads has a tendency to get softer (more compliant/squishy) over time this will affect the tonal balance. Treble has some sparkle but isn’t sibilant or harsh, mids are darn near perfect, and there is bass roll off but it’s a textured and detailed bass. The bigger the deviation the stronger the effect. Due to their open-back design, these headphones don't offer any isolation below 1KHz. This also points toward less refined treble. The filtered K702 (the right plots) show the overshoot is removed but there still is a second pulse. It means that they are able to output these frequencies. October 8, 2016.

Accessories: 3.5mm adapter. and the same isolation level as K701. When they eventually do graph the 612 I’ll update the chart. Collapsible: no Most measurement sites have some smoothing applied which ‘irons flat’ sharp peaks and ‘wiggles’. The mids look better as the measured signal looks more like the applied square-wave but does show overshoot and a lot of ringing. This way the plots are overlaid and it is easier to show the tonal balance differences.The headphone does not react much to higher output resistances other than in level (9.4dB). It shows no linearity issues at all, they all overlay.
