Sony MDR-NC300D Headphones (Old Version)

Highly recommended for lovers of movie, music or audio books in aircrafts or public transportation. For obvious safety reasons, pedestrians must not use these earphones while walking on the roads.I have been using Sony noise canceling earphones since over 20 years ago and have been using 4 or 5 different models. The sound is good and the noise canceling function is really effective in aircrafts and underground train. Accordingly, do not have to turn up the volume to overcome the noise outside which I believe is heathy to the ears.As for this model, I like the original case which comes with the earphones. The case is long shape, handy, with two small pockets inside for the two earpieces, and, two other wider pockets for other items. The cables can safely be folded inside and loosen very quickly upon unwrapping the case. It offers good protection to the earphones and the cables.I love this model so much that I bought this 2nd earphones of the same model while I am still using the 1st same model earphones on a daily basis for over two years. Just worry that it may not be available from the market soon. Even if a newer model may be available, the case may not be available.
