I personally find active headphones uncomfortable. Large studio headphones are designed for long term use.

  The reference was not to 'active headphones' (e.g. for running), but to 'active noise cancellation' where an "inverse wave" (inverse to incoming noise) is played to cancel out sounds. These can be in both in-ear or over-the-ear form.
