The daily train riders with over 300 kilometers I had been used to the old headphones, because the suppression of ambient noise in the ICE worked very well. Unfortunately, the old headphones are no longer available.
, So I know how good can be the noise reduction and was therefore very disappointed when I tried this Pionieer-in-ear headphones. Compared to my old identical expensive headphones I have to say, unfortunately, that is as good as no external noise suppression determine. Furthermore, I also noticed that the sound is not in itself particularly well.
Both together makes these headphones for me unfortunately useless and I have sent them back. Unfortunately, I've found so far still no substitute.
Unfortunately, I can not recommend the purchase.
