I’ve been using a custom molded in ear set from Tactacal Hearing for several years. I’ve been well satisfied with the hearing enhancement and the suppression.

RE: Tactical Hearing / Tim Sparks: My experience;
I purchased this defective product on the advice of a friend and outfitter, who I will save from embarrassment by not naming here. I was gearing up for a dangerous game hunt in Africa, and so was willing to pay the $3000 + to give myself an edge in the field. Long story short, they failed in the middle of pursuing a wounded Cape Buffalo. Not a good situation. Disgusted with the product, and with myself for being suckered into paying over 3 Grand for such garbage, I threw them in my field kit and tried to forget about them. I did pull them out a few times to use as hearing protection for shooting, but they never amplified sound again after that first outing. They were essentially a super comfortable custom molded ear-plug that cost three thousand bucks.
I was too embarrassed and furious to contact Tim Sparks again after being suckered so badly the first time. Couple years later I was fishing with my friend (who was there when the units failed, literally the month after I purchased them.) He asked if Tim had taken care of the issue, and I told him I never tried to find out. He encouraged me to contact him and send them in, assuring me that Tim Sparks was an honest guy and would take care of the product. So I did contact Tim, and he said "sure, send them in." I told him I was going to be hunting in Zimbabwe and would like them back before that. "No Problem", he assured me. Well, I went on my Zim hunt with no Tactical Hearing units, and without even a communication from them whatsoever. When I returned a month later, I again contacted Tim and asked what was the deal. He sounded surprised. "Oh, nobody contacted you? Well its been three years so it will cost you another $515 to repair the defective unit," Never mind that their website claims that they stand behind workmanship defects for 5 YEARS. What a crock, or should I say crook. Tim Sparks wants to charge me $500 Bucks to repair what is most likely a defective solder joint. Slimy, crooked bastards, don't get suckered like I did.
Postscript: I just returned from overseas to find the defective product had been mailed back to me, four and a half months later and unrepaired.
