Summary: Very disappointed in these as one side stopped working after 6 months rendering them useless. I later learned that this is a design fault and has happened to many others. Sennheiser are damaging their reputation by continuing to sell this product.
Summary: I was quite happy with this earphones, but they stopped working after just 4 months of use. The refund policy is only one month, which is quite unfair. I'm very disappointed. I used to buy everything in Amazon, but after this I will think about it twice as there's no guarantee, this headphones...
Summary: I bought these to replace a similar pair that finally gave the ghost after many years of constant use. Up to now these have performed very well. They are quite big tho so may not suit everyone UPDATE purchased these in April 2012 and they have now stopped working - very disappointing.
Summary: I have had 2 pairs of these headphones and both pairs have stopped working after 2-3 months. There is obviously a design flaw with this model as both times the sound has stopped coming through one ear. Incredibly frustrating and for a supposedly reputable manufacturer, really disappointing.
Summary: Very disappointed with this product. I have been accustomed to using the original PX 100 headphones for many years, which were very impressive, and performed well above their price tag. Based on this, I had expectations that the newer PX100-II would be even better. What a let down!
Summary: An excellent pair of 'phones, seemingly sold with a two year warranty. However Sennheiser have refused to honor the two year warranty because in their words "The Amazon Marketplace is NOT an authorised dealer.
Super Kopferhörer klanglich, aber Kabelbruch am Stecker nach 1 Jahr, dann nur noch ein Kopfhörer nach ca. 2 Jahren

Summary: Ich habe den Kopfhörer damals Nov. 2013 gekauft, wegen der positiven Rezession. Klanglich ist der der Kopfhörer wirklich sehr gut. Mein Sohn (11) hat den Kopfhörer regelmäßig benutzt und war auch überzeugt.
