I am just a Koss sound fan, I know their limitations because I have listened to better quality headphones like AKG 712 or Hifimans but I love the price-quality factor. I just want to have them all : ) I prefer open headphones for the comfort and natural feeling sound. For takeaway headphones the visual factor is also important for me so say nono to KTXPRO 1 (which honestly are one of the better sounding koss 60ohms imo) but KPH40 style seems okay. I already have wireless IEMs (Edifier TWS1 pro). Im gonna check Grado's in the future for sure

Thanks for the reply, what im after is basically mobility and comfort so i can take headphones outside without worrying they will break, i already own akg 712 pro and koss ur40 for home use

Thanks, question remains if its possible to put them back after ripping the cans out. Given that kph30i headband will propably desintegrate sooner or later maybe i will just buy additional kph40 just for the band
