- Great replacement/copy of AfterShokz Aeropex (2.5x cheaper)
- The lowest volume level in Huylou, as for me, is far from low and is average. In this sense, AfterShokz Aeropex is better. in them you can lower the sound both to low sounding and to extremely low sounding. Although I admit that this can be somehow adjusted in the settings of the headphones or phone.
