Well, personally even though portapro is NOT meant for sports they work just fine since I use them for jogging.
However, their 'sturdy' built quality "cough" broke when I tripped. So I got my sportapro and tried em on to see
if there is any kind of difference.
Built Quality and Material
Almost identical. Metal headband with cheap plastics.
They are much more fragile than most people believe. I mean, getting face palmed to the ground is not what most
people consider when judging the toughness of headphones but the poor connection between the driver and the
main body itself is indeed weak.
Sportapro apparently looks more awesome to me since their solid black color looks nice compared to this
sky-blue shining plastic portapro...but that is pretty much it.
I am not a master-ear, but these apparently same looking headphones didn't sound the same.
Sportapro hits more harder than already-base-overpowered portapros (I am a bass junkie so this was cool with me ^^)
I think the sound is 'muddier' compared to the Portapro. The High and mids are not as-clear.
The only advantage over buying a sportapro over a portapro is the base that hits harder.
If you are not a fan of overwhelming base, well, pay 10 dollars more and get a Portapro I guess.
Unfortunately this awesome cans made some weird clipping noise as the volume went up.
This noise problem is not as bad as my Crossfade LP, but compared to portapro this was a bit of a let-down.
Guess I expected too much from a 20-30 pair of cans.
Although it was not as good as I expected, the koss sportapros are still amazing. They are just not as-amazing
as the portas. Anyway, this was my brief review on these cans.
Thanks for reading.
