Please give some reviews on the mentioned subject.
Thanks a lot!
I listen to all musics. Sound quality is important to me.
So far, i am just a beginner for audio so i didn't own any dac and amp but i am willing to purchase them.
No headphones and thus keen to obtain one of them. >.<
Budget should be around SGD500 to 600. I am from Singapore.
Semi Portable and semi noise isolation is acceptable for me.
Of the ones you listed the B&W P5 are really the only portable option. Both the AKG K701 and Sennheiser HD650 are open headphones so they leak sound and let sound in. They also like to have an amp to sound their best.
If you're looking for something to work with all genres I'd probably go with the Sennheiser HD650 out of the three. The AKG K701 is nice, but has less bass which makes it not great for some rock, hip hop, electronica. Both really need a good audio chain (source/dac/amp) to sound their best so keep that in mind when looking at prices.
