Love these small over the ear vs ear buds when lying in bed. Sound is great and can lay on your side without the pressure from the earbuds digging into your brain :-) Price was a little high, but great quality, sound and fit!

Eindelijk een clip-on met voldoende bass. Koss geluidskwaliteit! De KSC75 voor thuis, deze rakker voor on the road. Klein en licht. Ik draai veel dub met flinke lage tonen en deze geeft t fatsoenlijk weer. No brainer!

Le cuffie suonano bene e il venditore é preciso e affidabile. Sono arrivate 3 gg prima del previsto. Soddisfatto

J'utilise ces écouteurs pour une activité qui n'a rien avoir avec la musique donc je ne peux pas juger de la qualité du rendu mais ce sont des écouteurs dont je ne pourrai m'en passer pour mon utilisation. Par contre le câble d'origine est bien évidemment trop fin et certainement assez tôt vous aurez des soucis avec. Je l'ai changé par du plus costaud et souder un jack de meilleur qualité (neutrik).
