On page 1, you say noise canceling is relatively new. On page 2, you say the technology dates from 1933. Which is it?
On page 2 you say 'the stereo rendering and the detailed level of sound. The former gives you the impression of listening to a breadth of notes instead of a limited range of sounds. The effect of the latter is breathtaking.'
When you say stereo rendering, I think you mean frequency response, which is a well understood term that should be used instead. The stereo effect should be the same on all earbuds, as they all are placed in the ear, the same way. I am not sure what 'detailed level of sound' is but you also seem to use it as frequency response.
Perhaps you mean low distortion, or low background noise? It is
most unclear.
On page 3, the beats headphones suddenly become earbuds.
As others mentioned, you neglect all measurements.
This is a junk puff piece, full of factual errors and minimal
content. I am amazed at the decline of tomshardware.com
