The BaByliss AS773E Hydro Fusion hot air brush and the BaByliss Hydro Air Fusion differ in several key aspects, despite similar packaging:
## Key differences
- Technology: The AS773E uses Advanced Plasma Technology, which utilises two ion sources to emit both positive and negative ions, reducing frizz and static and moisturising the hair.
- In contrast, the Hydro Air Fusion may use a different ionic technology or a modified version of plasma technology, but specific details are not explicitly mentioned in the sources.
## Functions and settings
- Temperature and speed settings: The AS773E has 2 temperature settings and 2 speed settings, as well as a cool air function for setting styling.
- The Hydro Air Fusion could have similar but possibly different settings, but this is not specifically mentioned in the sources.
## Attachments and materials
- Attachments: The AS773E comes with a large rotating 50 mm round brush with ceramic coating and a bristle guard attachment.
- The Hydro Air Fusion may have other or additional attachments, but this is not clear as specific details are missing.
## General application
- Areas of application: Both devices are suitable for smooth-glossy blow-dry looks, smoothing, waving and adding volume, but the AS773E is especially designed for reducing frizz and static.
Without specific details about the BaByliss Hydro Air Fusion in the sources, it's difficult to pinpoint all the differences. However, it is clear that the AS773E stands out with its Advanced Plasma Technology and specific functions such as the cooling air function and rotating ceramic brushes.
