I used to plug this into my PC and listen trough my speakers. Sound quality seemed good and all. Then I paused the playback and plugged in my headphones. Pressed play and about 150DB comes blarring out for 1 second before I can unplug the damn thing. Came to the conclusion that when plugging in headphones the volume goes up times 10. This is a dangerous device and now I have light hearing damage because of this thing. Worst purchase of my life, I hope they solve this or put a big warning label on top because this i just really bad. So be warned.
