Mi favorite piece of technology is the headphones Grado The Prestige Series sr 80e. I asked this headphones when a Friend traveled to New York city because the oficial shop is there and is a product handmade.
I use the headphones when I stay in my home without none sound because the headphone are of open category, this means that the sound comes out and there is no eco in the ear.
When I have to work to workshop alone, the headphones are the best partner and I like it because I love the music and I need a good headphone to listen to songs.
I believe that if I had not the Grado The Prestige Series sr 80e I think that i will not affected it because I would not know a better sound quality.
I love my headphones.
