I have recently got this driver out of curiosity and with a thought to use it in office, however gotta admit that it is rather poorly designed. With Nova Basic (which it came with) it sounds good with vocals and outright horrible with anything else, especially electronic or any intensive music. Reminded me of old Audio-technica AHT-7, but worse than it (ATH-7 is much better with types of music it is compatible with).
Plugging Airbow SC-1 into it I was able to get an acceptably okay sound, but nevertheless disappointing.
To put it short: this driver is to be avoided.
