Many people have already asked me this. In German: "Es ist bereits angewachsen" — is it already grown onto you? Because it is literally always on my neck. Even on stage during keynotes. Even during ultras.

Some have jokingly said it looks like someone is controlling me with a remote control and feeding me inputs via a voice in my ear. The OpenRun 2 is always there. I have had three or four pairs. One got stolen. One I destroyed. I would not live a single day without them.

"It is very nice with the ears open — you hear yourself speak, and you are not just closing everything down. You have a bit of contextual and spatial surrounding. You are not fully isolated."

When you close your ear with bone conduction headphones, the sound actually gets louder and more intense. A few cents on Amazon: small mechanical earplugs. Put them in — the music quality goes up, and the surrounding noise goes down.

Two modes: earplug alone = silence and focus. Earplug + Shokz = enhanced audio. No compromise.

The windscreen foam you see on professional microphones — the kind from old TV headsets. Buy one. Put it over the Shokz microphone. Eliminate every kind of wind noise.

I can ride my bike at 40 km/h with full headwind and have crystal clear calls. Complete game changer. Available on Amazon for cents. Standard size fits the Shokz mic.

The Shokz are the microphone layer for the whole system. I dictate into Wispr Flow through them. I call into my decisions interface through them. I listen to podcasts during Zone 2 training through them. Always on. Never closing off the world.
