I see a lota members use Koss headphones , how do there compare to detector dedicated phones such as KillerB , Greyghost ect ???? I had a pair of killerB II optimas but they didnt go low enough in volume on my Tesoros and caused my eardrum to reverberate , so Im in the market for a replacement been considering Rattles , but the cheap price on the Koss phones is atractive but are they any good ??
