From The Truth About Guns:

How is the cost kept down? One way is by eliminating excess tech. A lot of ear protection I’ve reviewed lately has Bluetooth, and while I like it well enough, I don’t use it often. Judging by the comments section, lots of you don’t either.

There’s no need to pay for a feature you don’t use; let the premium-priced headsets offer that. That’s the Bluetooth hardware, the on/off/connect button, and the volume controls—eliminated.

The battery cap pops off easy enough, sliding upwards like so many other brands.

A little bonus feature the Savior Equipment Apollo offers that most don’t? Patch panels. A little strip about 1″x2″ on each side of the headband allows you to attach your own patches via velcro hook loop pile, or use the included American flag and name badge patches.
