So I've been looking at some headphones for use with my laptop, but mainly with my iPod, with a frequency range of 5-40,000Hz. But the only headphones I can find have 6.3mm connection, will using a 3.5mm adaptor result in any loss of sound quality or frequency range? Also, if I'm using these with an iPod full of mp3 / whatever the Apple format is, is such a frequency range even necessary? I just want to get the best sound quality possible out of it. Thanks!
Technically any extra cables/connectors can't help the sound, but I have not noticed any issues using large>small or small>large adaptors. If you are curious about the frequency response you can hear from your headphones try out the ones you have with the first two samples on this website: The Ultimate Headphones Test Typically adult hearing is between 20hz-20khz, I tried mine and got a range between 10hz-16khz. The Denon AH-D2000 have a range between 5hz-45khz (not that you need it) and have a 3.5mm connector.
