Also, as of where I am at in the game, traveling also takes time on the boat I have. Save your money and buy direct from Nissan. plastic. However one of the 2 buds no longer produce sound only after a few days. Ive owned them for over a year and couldnt be happier except maybe for the high initial cost. At low volumes, the A1 sounds like a non-portable high quality speaker connected to mains/power supply. I’m always a little worried that these things are actually just re-packaged and labeled as new when they’re actually used but that was not the case here. They said the buds didnt hurt their ears and the sound was great. I bought them for a wedding recently. I love my music.
