Yeah, just follow the posts of the AtPro daily end users...some use the blacks in the water and some use the blues...Some use aftermarket GG's and the like...
Its hard to give you a solid answer....All of our hearing is different. I bought my rig off a Forum Sponsor, they came with the blacks and I added on the blues on the same transaction...
So I took the blacks, cut off the G plug and soldered on a 90 degree right angle jack and used them on an alternate rig from a different mfg even...They work great on account of you got the stereo volumn adjustment so you can get the proper audio balance...I like the blues too though, even though they dont have that audio balance adjust feature, I have used them for years with no trouble...they stop me dead over a target with a hard volumn...
Phones are VERY important! This is an Audio Primary Sport! You cant find things if you cant hear them, and like I said, everybodies hearing is different. It sometimes takes a while to find the right phones for YOU! You gotta be confident with whatever way you go though...
All this said, theres massive gold/silver found by guys running just the stock blacks...so hey...dont know if this helps you or not...Big Gold found with the stock blacks all the time, so right out of the box you are not missing much if anything regarding the stock phones...
