AKG K702, Burson Conductor 3 Reference

So far I enjoy it a lot, tho dedicated app for Windows would be great where I would for example adjust curves on Equalizer. Maybe a gaming settings too? Since I use it with my PC via USB connection. So far sound are amazing, plays way better than my AIM SC808 on stock setup. :)

The System

Listening with

AKG K702 · Headphones: open-back, dynamic, circumaural

Impedance: 62 Ω
Sensitivity: 105 dB SPL/V ≈ 92.9 dB/mW (calc.)
Frequency response: 10 Hz – 39.8 kHz
Plugs / cables supplied: detachable 3 m cable
Other: max input power 200 mW

Matching notes: At 62 Ω and 105 dB/V, the AKG K702 is a low-impedance load, and a fairly demanding one: about 1.8 V (51 mW, 29 mA) for 110 dB SPL (calc.). Burson does not publish a 62 Ω rating for the Conductor 3 Reference. Its 32 Ω and 100 Ω ratings (5 W SE; 1.75 W SE) fall either side of it. The Conductor 3 Reference’s 0.5 Ω headphone output impedance is 1/124 of the load. ^{[1] [2] [3] [4]}

Specs from manufacturer data unless a source below says otherwise. “calc.” values are worked out from those figures (V = √(P × R); 110 dB SPL used as a loud reference level). Gear listed without specs is not in our spec library yet.
