The Philips Sonicare DiamondClean dual pack HX9392/39 is an older DiamondClean design, but its box suits couples on the move. Each handle gets its own USB travel charging case, and a charging glass sits at home. The five modes are named clearly, including Polish. What it does not have is any mention of a pressure sensor or app, which newer pairs on this site include.

In its favour

  • Two USB travel charging cases, one per handle, so each person can charge away from home.
  • Five modes: Clean, White, Sensitive, Gum Care and Polish.
  • A charging glass sits on the shelf, and the pack uses a UK two-pin bathroom plug.

Good to know

  • The listing does not state how many brush heads are in the box.
  • No pressure sensor or app is mentioned, unlike the newer DiamondClean 9000 pairs.

Our take

Two cases that charge from USB

The listing states two handles, two USB travel charging cases and a glass charger. That makes it the only twin pack on this site with a USB charging case for each person and a home charger as well. The spec list also mentions a rinse cup, which is the charging glass.

A UK two-pin bathroom plug is named in the title. The listing does not say whether a USB lead or plug is supplied for the cases.

Five named modes

Philips lists Clean, White, Sensitive, Gum Care and Polish. Having both White and Polish suits someone focused on surface stains, while Sensitive is there for a gentler session. Intensity levels are not mentioned.

Philips claims up to seven times more plaque removal than a manual brush and a whiter smile in one week with the included DiamondClean head. Those are the maker's figures.

Gaps in the listing

The number of brush heads is not stated, so assume you may need to buy a second one. No pressure sensor, app or display is mentioned, which sets it apart from the DiamondClean 9000 dual pack and the Sonicare 7100 two pack, both of which warn when you press too hard. Battery life is also missing.

Who it suits

This pair is a fit for couples who travel often and value USB charging cases above smart features. If you want pressure feedback, the Sonicare 7100 two pack also gives each person a charging case and a USB-A cable, with a sensor that reduces vibration.

The set weighs 1.18 kg according to Amazon, which reflects the glass and two cases. Packing just one case per person keeps a weekend bag light, since each handle sits inside its own charger.

Verdict

The DiamondClean dual pack makes sense if two USB travel charging cases and five named modes, including Polish, are what you are after. For pressure feedback and app guidance, the Sonicare 7100 two pack is the better travelling pair, and the DiamondClean 9000 dual pack suits couples who mostly brush at home.
