Howard Leightby Honeywell Impact Sport Sound Amplification Electronic Shooting Earmuff, MultiCam Black (R-02527)

I purchased these in the fall of 2020 for quail & pheasant hunting. They worked well for that purpose. This year I used them for squirrel and dove hunting. Not at all acceptable. They receive interference and produce a buzzing noise when I use my Bluetooth remote speaker and game call app on my phone. First let me say I have been a HAM radio operator since Nov, 1963. I have a Bachelor's Degree in Engineering with a major discipline in radio frequency transmissions. I also worked as an engineer at a $150 million dollar government facility. So I would say I have considerably more experience in the field of radio frequency transmissions than your average squirrel and dove hunter. Unfortunately, after retirement I no longer have access to any frequency generator or spectrum analyzer equipment to test exactly what frequency this headset is receiving Bluetooth interference on.This headset is not sold as "Bluetooth compatible." So I would say the manufacture did not spend any time, effort, or money testing if it would receive interference from a Bluetooth transmission source. Mine do. When I turn on the Bluetooth capabilities in my Samsung device, I immediately receive a buzzing noise in the headset. I turn off the Bluetooth capabilities in my device, and the buzzing stops. This headset picks up that transmission and produces a buzzing noise in both ear cups. Adjusting the volume control on the headset does not change the volume of the interference buzzing. I tried using a second device and received the same interference buzzing. I'm not going to get rid of a $600 Android cellphone, or a $250 Android tablet because of Bluetooth interference in a $62 headset. Would you? I purchased another brand of headset, also NOT listed as Bluetooth compatible, and do not receive any interference buzzing. This headset will be used in the future for purposes only when I am NOT using Bluetooth. I would not purchase this model headset again.

Wore it to the shooting range. It worked great. The thing I liked best was when I turned the volume up, I could hear talking better with them on than with them off!

They are a bit small around me ears (as an adult male) but fit my wife perfectly. They do a great job blocking out the noise from firearms, but allow you to hear conversation and other relevant sounds. Great battery life as well.

These earmuffs worked very well...great noise suppressio and amplification of the range commands by the instructors. Comfortable for 7-8 hours of range time each day for a week at Gunsite Academy.

Overall I like the compact feel of it, and the noise reduction is good. Still gotta double up with earplugs though - that's in general for indoor ranges.
