I did it as soon as I got them and they are genuine :)Anyone who complains of sound leak have only themselves to blame. but it juts stopped working after a few weeks of use. I liked the design - looked rugged, durable, and sturdy. Poor design and it should have included a bag of these with the fryer as replacements. 5N. not little pod units that clip together and can pop off in some situations). ?? great quality and value for money! The audio quality is "good", but you may find better. As a whole package I really recommend it. Highs didnt really change that much but does sound a little more spacious and accurate.
