Before TetherTune, I was tangled in earbud cords every single workout. Now it clips right to my shirt and keeps up for hours without missing a beat. My gym sessions feel effortless now.

Based On Real and Honest Experiences
I run a contracting crew and need gear that can take a beating. This speaker rides on my toolbox all day, handles dust and bumps, and the mic makes hands-free calls easy on site.
I doubted a speaker this small could handle real trail noise, but TetherTune proved me wrong. The battery lasted my entire three-day hike and the sound cut through wind without distortion.
