Query: OK, BUT....

In 2003 I purchased some non-foldable, standard on the ear Philips headphones from WALMART, for about the same price - the sound/bass volume was superior to these.I thought..well for the price it was'nt bad, well after wearing them on PUBLIC TRANSPORTATION - they hardly competed with the bus's noizes. This is even after using a heat gun at low temp, to get them to cover on my ears.These would be OK for big kids, but to me an ADULT, needs something more robust, yes the fold up mech is nice - but in the end if the audio is not up to snuff, it just won't matter.As a point of reference, the older SONY ear clipz sound is better, better still are SENNHEISER PX 100, that also fold - they have FAR SUPERIOR audio/bass/volume quality.I will be giving these away soon.NOTE: Philips can produce some nice headsets, to me this just is'nt one of them.
