Philips Beard Trimmer 3000 Series BT3660/15, 40 Settings, Waterproof

Self-sharpening metal blades give the Philips Beard Trimmer 3000 Series BT3660/15 a durable cutting edge for regular facial-hair grooming. The blades do not require oil, and their non-corrosive design makes cleaning straightforward.

A precision dial provides 40 lock-in length settings in 0.5 mm steps. Set the length for short stubble, a shaped short beard or a longer trim, then use the Lift&Trim comb to lift and guide hairs towards the blades as you work.

The trimmer is 100% waterproof, so you can rinse it under the tap after use. An ergonomic grip is designed to make handling comfortable and controlled during your routine.

What stands out

The combination of fine length increments and two included combs gives you room to tailor a beard trim rather than relying on one fixed cutting length. The short comb covers 0.5–10 mm, while the long comb covers 10.5–20 mm. The dial’s 40 settings make it easier to select and lock in a preferred length for shaping or maintaining a consistent look.

The Lift&Trim system helps guide hairs towards the blade, supporting an even, precise trim across the beard. For a practical routine, select a setting, move the trimmer through the areas you want to shape, then rinse it under the tap. Its waterproof construction and non-corrosive blades help simplify clean-up, and no blade oil is required.

Key takeaways

This cordless, battery-powered beard trimmer includes a battery indicator that shows whether the battery is low, empty, charging or full. The supplied USB-A charging cable offers a convenient way to charge from a USB-compatible power source. A power adaptor is not included, so plan to use a compatible USB power source you already have.

In the box are the Philips Beard Trimmer 3000 Series, the short and long combs, a cleaning brush and the USB-A charging cable. The maximum cutting length is 20 mm. Compared with a trimmer built around one fixed length, the adjustable dial and two combs suit routines that move between close stubble and a longer beard, they also make it straightforward to keep to a chosen length from trim to trim.

Cleaning & care

Rinse the waterproof trimmer under running tap water after grooming. The non-corrosive metal blades are designed for easy cleaning and do not need blade oil. A cleaning brush is also included for grooming maintenance. After cleaning, use the battery indicator to check the charging status when needed.
