I share the misfortune, in my case it was an accident between the two drivers... and also a naughty nephew who almost made the n90q's useless... in both cases it was almost completely solved, but it is never the same

I'm looking forward to the k100 500 ohm, the 60 ohm was the second option

qigom k100? (32/60/300/500/700/900 ohm?) in these offers buy the 500, I hope you surprise me

i've been testing some less expensive qigom models and the n90q is fabulous and the others have their own charm as well (hd800, hd650, 777)
