Comparison of Norelco 2D & 3D Shaver Review
The Gyroflex (Sensotouch) 2D basically refers to the corresponding Philips razors -- the Norelco 1150X & 1160 X and the Gyroflex (Sensotouch) 3D is associated with the shavers - Norelco 1250X, 1280X & 1290X -- and it is this difference in technology that we are comparing & contrasting in this account. From which you will hopefully get a clearer overview as to what exactly each technology is (how it differs, how it is identical etc.) and ultimately help you decide 'which you prefer' from the Norelco 2D Vs 3D and whether you want it (and are willing to pay that bit extra for it) to be featured in your shaver.
Gyroflex SensoTouch 2D -- (Two Dimensional)
This term is basically describing a two dimensional (hence 2D) "contouring technology" (which you can check out here with the Norelco 1150x shaver) featured in the 1150X & 1160X sensotouch shavers that enables two movements: i) pivoting with circulatory movements and ii) being able to tilt inwards. The idea being that it will flow with your facial contours as to reduce irritation and minimize pressure (particularly catering for those with sensitive skin) but still achieve a close cut shave.

Gyroflex SensoTouch 3D -- (Three Dimensional)
As you have probably already worked out, the GyroFlex 3D technology is simply a more advanced version of the 2D (and can be seen in practice -- along with more information -- within shavers such as the 1250X sensotouch model) and basically features the two components mentioned with the 2D i.e inward tilting as well as circulatory motions -- but also a third independent and dynamic component is added, which is the ability to flex. This allows the shavers to follow your natural facial shape to an even greater degree of accuracy in turn keeping shaving discomfort to an absolute minimum and producing a super clean & precise shave.

The Difference Between SensoTouch 2D & 3D
As seen then both technologies are an overview of what components, adaptive abilities are in place to make sure you have a quality (non-irritable) shaving experience. Both being installed with a tilting motion as well as rotary movements -- and the latter (3D tech) being able to offer an even more comfortable & close cut shave due to its flexing ability (precisely following & adapting to your facial contours).
Comparing a SensoTouch 2D and 3D shaver, is rather vague given that there are a range odf models within each -- for instance it could be the 1150X vs 1250X or the 1160X Vs 1280X, whereby the former is a 2D razor and the latter a 3D version (hence 2D Vs 3D). When in truth there are differences even within their own 'range' -- for instance the 1160X model is arguably a better and more capable shaver than the 1150X -- yet they are both 2D sensotouch shavers and likewise with the 1250X compared to the 1280X (with the 1280X being the better shaver) but are both 3D shavers.
Other Things to Consider
So obviously when looking to get a Norelco shaver there are many other aspects and features to consider such as the shaving features (are they fitted with an aqua-tec seal, do they offer dual precision for instance?), practical specifications (need to consider the run time, travel locks, cleaning solutions etc.) as well as other general information (the accessories, warranty coverage, ergonomic design?, the price). Not, just the 'added' ability of flexing.
Would you get a Philips Norelco 2D or 3D?
Furthermore, if you have any questions, comments or concerns regarding either the comparison article of the norelco 2D Vs 3D (still need further clarification?) or about any of the models mentioned above or within the respective electric shaver range (i.e 1150X, 1160X, 1250X, 1280X and 1290X) then please do not hesitate to mention them in the comments section that you will find just below and we will be sure to get back to you as fast as possible with the most appropriate answer.
