So I am a person who likes to use earphones a lot. I like the design, the sound they produce and the comfort. I am even using earphones at home but someday I might get some high standard full size headphones. Currently I am using the Sennheiser MX 580 and am very pleased with them. The detail is really incredible, as is the frequency responce in the midds and the heights. The bass could be a bit stronger and deepder and they could sound a bit warmer and lifelike. For sure they are incredible earphones, much better than any earphones with the 60 at the end. I am wondering however, whether there are earphones that are even better. How are the Sennheiser MX 680 or 685? How are the Audio Technika c505? Unfortunatley the expensive Audio Technika are not available in europe anymore, so they are very expensive to buy from Japan or South Corea. How could they removed that pair of high end earphones, I wish I would own one and enjoy music in very high sound quality. I would appreciate feedback on the questions and probably other recommendations aswell.
