They did feel extremely light and for many this will be a very positive benefit, as wont strain the ears and can be used onstage even for the most energetic musicians.
It doesn’t mask or distort like other earphones I have tried that seem to vibrate and resonate. Texturing is slightly thick but not heavily coloured.
I am pleased to say that the treble has no observable harshness or sibilance and as a result the HEM8 can be used for longer listening sessions as these do not result in fatiguing or soreness.
The Optoma NuForce HEM8 should be very agreeable to many audio fans out. Build is decent and isolation is easy to achieve. Overall signature is relaxed with strong bass presence, excellent imaging and nice musicality.
