For a while I used the RPG headphones that came with my Safari. I notice that there little or no difference between the tones that the Safari made from various targets as far as my ears could distinguish. I've previously owned several Safaries before so I am familiar with it's tones. I was begining to think that it was deffected. I have a pair of JVCs with great sound that I like that have a broken headband. I removed the speakers from them and placed them in the RPGs. Man what a difference! The various tones are so much more distinguish especially the lows from the highs. Any new users ( if you don't already know) invest in a good quality pair of headphones especially if you hunt in all metal. They really help to sharpen you skills.
