Review: Finally the right setup for my shooting protection - I have an Import Sport hearing protection which has an audio input. Works for iPhone, whatever. Ive been looking for the right setup to get it to work for me as a headset for Paintball. This plus a Headphone Audio Cable with Mic Boom cable did the trick. I have looked forever for the right combination to be able to use the hearing protection with it (also enhances sound). Contemplated throat mics but only one I found offered 3.5mm jack and it was not a trustworthy site and didnt appear to offer good pickup. Tons of other mics out there but none offered the right outputs and I dont solder. https://smile.desertcart.com/gp/product/B0758RJ56Z/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 I was also able to readily hookup an old Xbox headset with mic. I was also able to get that plus the Impact Sport to work using a headset Y but that left me with another speaker. I guess I could tear it apart and remove the speaker. Also able to get another mic (that also still had speakers) to work by using a headset splitter to mic and audio going through the other headset Y. But neither of those two were ideal with the Impact Sport. If I just wanted the Xbox mic that would have been fine, but in the woods with paint and potentially rain I didnt want to chance it. Still a good alternative for general use hiking or something. I swear, Ive researched for days over the course of years to find the right setup. I cant speak to its ruggedness. I can say out of the bag with the right connections its working just as I hoped.
Review: works as promised - Grade A - works as promised - adds a capability to the Baofeng DM-32UV

### ⭐⭐⭐⭐ This is useful if you need it.
*by M***Y on October 18, 2018*

If you're using a two way radio and already own some nice headphones with a microphone built in this is a great way to upgrade from those cheap earpieces that they come with. I use this with some Shure In-Ear monitors that have a great fit and noise blocking abilities, but also had to purchase one of these https://smile.amazon.com/gp/product/B074V1RDTP/ because the Shure IEMs do not have a microphone built into the line. My one complaint is that given the length of most headphone cabling you will be plugging into this thing, the length of cable on this unit is excessive. I end up clipping the radio to my belt and coiling this near it and activating the push-to-talk button from my hip. It ends up being a huge tangle of cables by the end of the night, but I still prefer that to using cheap plastic earpieces and going deaf from all of the bleed from a noisy environment.
