Hi all, so I've always used cheap earphones that come with your average smartphones. However, i have decided to take the "next leap" if you will, towards better audio. I had already upgraded to a Sennheiser 201 headphone, as an entry level pair. However, truth be told, i was massively disappointed by both the audio and the comfort, or lack thereof, of those headphones. They only merely sounded better than a £10 cheap plastic earphones and their comfort was downright horrendous, giving me headaches and jaw aches etc, when compared to my light-as-feathers cheap £10 earphones. Anyways, I have now decided to go with the AKG 701s or 702s (whichever when is the cheapest at time of purchase) since i have been told they sound identical. Along with that, i have decided to also opt for the Fio e10k amp/ dac. Now, my question is, are these too overkill to be used with mostly youtube videos (on 1080p or higher settings) as i mostly listen to music via that or spotify premium? Should i be looking for a cheaper alternative? I am merely buying these as a better "sound" experience and I will not be doing any studio work whatsoever in the foreseeable future. What sort of audio quality are these designed for? Is youtube too bad for these? Do i need to be using FLAC or other lossless formats?
