Took the plunge and got a set through Amazon. I have the Shure SE 846 and SE425 to compare to. Short version- 846 has unbeatable low bass but the Oriolus has great high end and channel sound separation. The SE425 sounds like garbage compared. Did some measurements using an Asus Xonar usb card with a calibrated Spl meter's line out and a plastic tube as a coupler-about 1 cc volume, 7 mm distance to the mic. All tests were done at least 2x to insure consistency. I did a spectrum test in RMAA to look for impedance issues on my Note 4 (1.5 ohm) and it was pretty flat--nothing to worry there. Sensitivity is close to the Se846 with Spl output within 1-2 dB same input volume. Square waves (90 hz): SE846 Oriolus: SE425 THD measurements: Oriolus: SE846 Frequency comparison: Channel matching: The 846 definitely has the edge in the low end but the Oriolus has a great treble extension that is very apparent in listening. I could never get good bass out of the Se425 and its about 10 dB down compared to the others. I am not going to go into subjective analysis but wanted some comparison data. I personally really like both.
