I don't have the Soundgear version, but in case you find it useful I wrote the below on the 'other' NZ hunting forum back in 2011. I've still got the same pair - still working perfectly (despite full immersion in the river one frosty morning!) and I still wear them everytime I'm hunting - .17hmr, 12ga and .270. If they stopped working tomorrow I'd be buying a replacement pair first thing.
My ones are Starkey Magnum Ears - Silver (Digital) Model. To get the bad news out of the way first - my set was $1600 from Dilworth Hearing. To get the same set from Bay Audiology was even more. If you start looking into these electronic ear-plugs, you can get both cheaper and more expensive models. Cheaper tends to cut into the audio quality (apparently), more expensive starts putting more hearing aid functionality into the plug - allowing you to compensate for existing hearing loss as well as protecting your remaining hearing.
I don't have any real hearing loss, but found out the hard way that my ears are prone to Tinnitus (permanent ringing) from loud sound exposure. It doesn't bug me most of the time anymore, but I'm really keen that the ringing doesn't get any louder.
The plugs I have are custom molded for my ears, so are very comfortable. You don't get sweaty ears like with ear-muffs, and they don't interfere with your rifle/shotgun stock. Volume is adjustable, and sound quality is near perfect. You can wind the volume up far beyond your normal hearing level, but there are diminishing returns on this - the sound of your own movements starts to swamp the extra sensitivity. Turned up to normal hearing level (or maybe just a touch more) there's no problem.
The plugs cut out instantaneously when you fire, but come back on quick enough that you can hear the "BOOM" rolling away up the hills. Although I haven't used them enough to be sure, I think they'd come back on quick enough to hear the bullet impact for the times when that's audible.
I've had mine for a couple of months now, and I reckon they're worth the money I paid.
One other thing - Dilworth will give you a 3-month trial period after receiving your new plugs. If you don't like them, all you pay is the initial $75 consultation fee. I had a long phone conversation with a shotgun shooter and audiologist - he tells me that they've never had a set returned during the trial period. Tells you something.
Happy to answer anymore questions if anyone is interested. I had trouble finding anyone with real-life experience with them when I bought mine.
Thanks heaps, exactly what I was after , someone actually using them , cheers
