- an excellent sound, as well as no obstruction in the bass, making a snug fit absolutely necessary.
- Ear cushions - for me, the full ones are either too little or, more accurately, not elastic enough for a comfortable and secure fit (even the larger ones). Even though there is a lot of information in the instructions, the initial setup is not very straightforward. The ANC (active noise cancellation) tests suggest that either I did not notice it or that it does not function very effectively.
