HEM4

It is a well-made earphone and the blue finish on the housings is smart without being too obtrusive.

Its presentation is very slightly forward, which gives it a consistently lively and exciting edge.

The use of an armature for the bass instead of a dynamic driver seems to lend it speed and definition that is very useful whenever there is a more complex arrangement to deal with and, as before, it does well to draw you into the performance.

In the noisiest surroundings, it is able to keep any interference at bay without the need to raise the volume.  Combines with the useful level of sensitivity on offer and the inline remote, the HEM4 performs well with lower-powered sources, ensuring it is a tempting prospect for commuters
