These earbuds aren't quite there yet. Though they are built like a tank and can be maintained easily, the sound isn't all that good. Audiophiles might steer clear, but DIY enthusiasts and eco-conscious buyers might want to take note.
Objective measurements from the SoundGuys test lab — overlay other models to see how this one compares.
Measured frequency response (dB) against the SoundGuys house target — the dashed curve. The closer the measured line tracks the target, the more neutral the tuning; peaks ride above the target, dips fall below it.
