I’ll be the first to admit, I’m not a huge audiophile, I know a bit about it but, not to the extent of most people. I recently just purchased some quality headphones – “Bowers & Wilkins p5’s” I must say they sound terrific! I love working at my desk with good music pumping through these things. When you turn them up it doesn’t feel like they are blaring in your ears. They feel more like you are in a room with a good sound system playing.
If you get the chance to check them out I highly suggest them. We sell them at Apple and they are currently on display so you can try them out before purchasing.
