I am looking to get my dad some top of the range headphones, where price is not an issue. He is a real audiophile with sensitive ears, but needs to get something for when he is not at home.
He would use them exclusively for opera and classical music (for example: Verdi, Puccini, Mozart, Handel, Haydn).
He would always use them away from an amp, so connected either to a portable CD player or MP3 player.
Also, I would be interested to know if there are any good headphones of this type that would also have a noise-cancelling option. I understand that noise-cancelling tends to hurt the performance, but I would be interested in any headphones that are good/great for opera when the noise-cancelling option is turned off.
(My dad would use them with the noise-cancelling option turned off most of the time, but it would be great if he could use them on a plane as well from time to time and then the reduced performance when the option is on would not be as important).
Thank you very much in advance for your advice.
