Hello! This is my first post here at Head-Fi, although I have been following some threads here for quite a while now..
Gonna be brief because I'm having to re-type this whole thing (grrrr)
Got some new headphones, first pair over $100. Ultrasone PRO-750's. Previous best were Sony MDR-7506
Doing some frequency sweeps, from this site: http://www.jlabaudio.com/burn.php
Followed the instructions to a T, always making sure my volume is at medium levels, and when the first frequency sweep starts (don't know if it's 20-20000 or 30-30000, it's the first one after the 3 noise variations) I can hear an audible electric/static sound playing during the last 10 seconds of the frequency sweep. It's only on that one particular sweep, and I've tried setting my DAC to 24/96k and 16/44.1k and get the same result. The other sweeps don't exhibit this static/electric sound during any part of them, only the standard sweeping tone/oscillations.
I use an Audinst HUD-MX1 as a DAC, and the volume never passes ~35% on the MX1, and only then for really old low volume recordings. (I listen to mostly classical, always at a moderate volume.)
Should I be worried about this electric/static noise at the end of this particular sweep? Is it a sign that the headphones may have some defect in them? I've only had them for about a week now, and have only run the burn-in for 6-8 hours at a time in 3 different sessions.
Thanks Head-Fi'ers for any help you can provide here! (Sorry if this is a noob question.. just trying to do it right.)
