SUPERNB SH50 Replacement Shaver Heads 6-Pack — Rounded Shape for Series 5000/6000, 5-Way Flex, Wet/Dry

If your Series 5000 or 6000 shaver has lost its edge, the SUPERNB SH50 6-pack gives you an affordable way to rebuild performance without buying a new razor. Designed for models with the rounded head configuration — including AquaTouch (S5xxx / AT7xx / AT8xx) and PowerTouch (PT7xx / PT8xx) lines — these compatible heads include three retaining rings and a cleaning brush to make installation and upkeep straightforward. The components are engineered to mimic the original design's floating action, letting the shaving head follow facial contours for improved closeness and fewer catches.

Which razors will these replacement heads fit?

These SH50 heads are made for rounded-shape Series 5000 and 6000 shavers. Confirm compatibility by checking your model number against the list or the rounded head design on your shaver’s head assembly.

• Compatible families: AQUATOUCH S5xxx, AT7xx, AT8xx and POWERTOUCH PT7xx/PT8xx.
• Common model examples: S5070, S5210, S5570, AT750, PT725, PT730.
• Works with shavers that accept rounded SH50-style head cartridges.

How do these heads replicate the original shaving action?

The SUPERNB SH50 assemblies use a multi-directional floating design and curved foils to follow jawlines and neck contours. That movement helps maintain close contact with variable angles and reduces the need for repeated passes.

• 5-way Flex floating heads that move independently for contour tracking.
• Curved cutter geometry for smoother skin glide and fewer snags.
• Durable foils and cutters designed for easy rinsing and extended use.

Can I use these heads for wet shaving and are they easy to maintain?

Yes — the SH50 heads are designed for wet and dry use, so you can shave with foam, gel, or under the shower. After each use the included brush helps remove hair; occasional rinsing under running water keeps them performing well.

• Waterproof design supports both wet and dry shaving routines.
• Includes one cleaning brush for daily upkeep and three retaining rings for secure reassembly.
• Simple rinse-and-dry care extends cutter life; replace annually for consistent results.

What do I get in this 6-pack and how often should I replace them?

This kit contains six SH50 replacement heads, three retaining rings and a cleaning brush so you can service multiple razors or stagger replacements. For most users, swapping the shaving unit annually restores original comfort and performance.

• Package contents: 6x SH50 head cartridges, 3x retaining rings, 1x cleaning brush.
• Recommended replacement interval: about once per year, depending on hair type and usage.
• Cost-effective option when compared to buying a new shaver.

Who is this for: The SUPERNB SH50 6-pack is ideal for owners of rounded-head Series 5000 or 6000 electric shavers who want to refresh shaving performance on a budget. It suits daily shavers seeking reliable wet/dry compatibility, travel users who like to keep spare heads on hand, and anyone who prefers replacing worn cartridges instead of upgrading the entire razor. If you need exact model fit, verify your shaver’s rounded head style and model number against the compatibility list before purchase.
