My headset is over 50 years old and I use it as an instructor often. The old M-4 mics went obsolete and the M-7 replaced it. Installation was easy peasy and the sound quality was perfect. Thanks for stocking this item.
I normally wear an xl for 95% of my shirts. I ordered a 2XL in this just to be safe. STILL too small. Sizing is crazy. You can do better. Charge me for a correctly sized shirt, I don’t care! But don’t do this.
I’m NOT taking a pic.
