I'm looking to buy my first reasonable pair of headphones. I listen to mainly classical music and these will be for use in a coffee shop powered from a laptop or iPhone etc. I'm on a tight budget of $150. I have no problem buying second hand to get in under this figure.
I currently have a pair of Beyerdynamic DT100s (long story how I ended up with these) anyway, thought they were fine until I listened to a pair of Grado 80i which blew me away. These would be in budget but from what I read they aren't ideal for classical music so if I can get something even better then boom! Thank you for your advice!
