There are three issues I’d like to cover in today’s lecture.
Firstly, cheap headphones:
I needed a cheap set of new headphones for listening to music at work, so I made the huge mistake of buying Sennheiser PX20. My office mates can hear my music better than I can when I use these, that’s just how bad they leak. Advice: do not buy these. If a friend gives them to you as a present, terminate the friendship. (To make really sure that others searching for reviews on these headphones do find something and to make my message even clearer: Sennheiser PX-20, or PX20, headphones suck. Completely.)
