The reason I like rocket dogs is because they usually run a bit narrow. I am a solid 8 and likely would need a whole size larger. Meine größeren Kopfhörer mit 250 Ohm werden wohl einen Vorverstärker brauchen. Der Fingerabdrucksensor wird hier nicht beeinträchtigt funktioniert einwandfrei. Needless to say I I left it on throughout the day (surprisingly comfortable) took off before bed 10pm. I have never known headphones of this brand to be tinny before. Great quality exactly what I expected perfect for quickly running out of the house or park playtime! Maybe ok for a big dude but not good for women. Na ja, eigentlich nicht. I love the headphones like it is so convenient and very useful especially for times when it is raining and you dont want the headphones to slap against your face.
