So far I have headphones from Philips SHS 4800 in sporting use. To the extent not bad in order and for 20 euros. Now use the Sennheiser OCX 685i I wanted better sound and the ability to clean the headphones. But I should have listened to the more bad recessions. I have never allowed to experience such bad sound. Despite several attempts to bring the headphones to your ear anyway, could not be improved. Added to this was that the bars are so soft that there is no proper concern. So the headphones went back. I did not know how good the old Philips SHS 4800.
