"Beforei fork out for these i prefer having my music in mp3 format, i read in reviews of the earphone versions of these that the music quality can suffer a bit unless its on cd or vinyl, is this true?
Ty for any help"
There is an element of truth behind that yes. MP3 is a lossy audio codec, its very nature means that when its converted to MP3 it loses alot of the 'unneccessary' parts of the audio file. CD quality is far superior to MP3, consdierably better tbh, if you think about it this way, the highest MP3 bit rate a file can have is 320 kbps, a CD that would be in 'Redbook' format (standard audio type for CD's) would have a bit rate of 1412 kbps per file, thats over four times more bit rates per second, just think of all the 'unneccessary' stuff the MP3 file is getting rid of, its an awful lot to be fair. Even other Codecs like .wav and .flac are far superior to MP3, with FLAC being the huge preferance as far as im concerned. IF you have expensive, top end Hi-Fi equipment and then plug these level of headphones into it them (well they claim their monitoring headphones so...) you will hear the difference between an MP3 and a CD quality file. If you dont, or you're listening to an iPod then you probably wont hear the difference. Hope this helped :)
