You keep $70 in your pocket.
The Bluetooth muff does everything the regular EXO Pro does. It amplifies range commands, your buddy, and ambient sounds up to 82dB, then cuts anything louder in 5ms.
And now adds a phone connection.
What that gets you: music between strings, a podcast during a long precision session, or the call from home you can't miss, all without pulling your ear pro off on a hot range.
Dual built-in mics mean the person on the other end hears you, not the bay next to you.
What it doesn't change: gel cups that seal around your glasses' temples, a fold-flat design, and a case that fits both.
