These earphones do not deserve to be branded "Beyerdynamic".
+Sound is clear and detailed, with the right ear-pieces
-My DTX101 iE earphones broke in 4 months! The right speaker just dropped out of its place, even though I had always stored them in the included pouch
-The included ear-pieces are rubbish, they are way too small to isolate any unwanted noises and do not play well with the actual earphones. I recommend buying sturdier, bigger ones
-Most of their products are made in Germany. The cheaper models, like these and almost all products under 100 euros, are made in China and it shows
Its kinda short but you get the idea, guess I could write here how these earphones changed my life and I became a Buddhist monk but I'll leave that to another review.
