The Echo Duo is a high-resonance dual-motor personal massager with a wide 30mm vibration head for a fuller, deeper feel. Two independent motors run 10 modes (3 speeds plus 7 patterns) in a compact 137mm body.
The Echo Duo uses a wide 30mm vibration head, so the sensation reads fuller and deeper than a narrow-tip design. Two independent motors run 10 modes — 3 speeds plus 7 patterns — at under 60 dB, in a compact 137mm body. $65, shipped free worldwide.

A row appears only when we have a published figure for that model — a missing row means we have not published it, not that the device lacks the feature. Control detail, battery and charge time are the three still being confirmed with the factory model by model. We would rather leave a row out than estimate it.
Rinse with warm water before and after each use. Clean with mild fragrance-free soap, rinse thoroughly, and pat dry. Store in the included pouch away from direct sunlight and other silicone products. Charge fully before first use.
Every model on this page is also available as a wholesale, OEM or private-label program from the same Dongguan factory. The published terms apply across the range:
