A different kind of (inexpensive) Audio accessory.

I've always had a headlamp in my toolbox.   Surprised at the many uses.  My favourite was illuminating the roadway on the pre dawn walking of the Spanish Camino.  Hope to walk it again in 2023.  

Good idea.  The tool I rely on is a small mirror (and a flashlight or two).  The mirror is not perfect but it does often help when I can't get my head back there or when my eyes don't focus too close or too far away.  I can read stuff and light stuff up, although it is reversed.  

I’ve been using them for years. Leaves your hands free for whatever you’re doing.

T Mobile gave them away last month.

Treat them cryogenically for an even brighter, whiter light. I know what I see.
