- Why spend so much money? Of course, because of the soundproofing, which is noise reduction :) Small office, 20 people in a room, noisy servers, router, printers, conversations - and now I don't care :) The battery keeps the day without question, yesterday evening it was 60%.
- Ears are a little stuffy out of habit, especially on quiet compositions, but then you need to add volume, it becomes easier. Voice prompts turned off after a day, interfere with phone functions.
