Have you, like me, constantly tangled when listening to music outdoors with the cable that selbige almost demolished, pulled the headphones from his head involuntarily ..... One can not imagine how much more relaxed you can hear without cable itself, or: has we heard once without cable, you can not imagine how you could ever hear with cable headphones outdoors! If it is then also to be a headset, which also comes up with an ingenious operating concept, the happiness is complete. The operation is in practice really awesome. Title and volume control via touch - Perfect! It sounds because even good? and how. While not without minor intervention, but through the free app, the necessary small frequency response corrections done quickly (root to 400 and more centers around 1000 Hz up slightly), already the sound is perfect. Short Conclusion: One of my best purchases recently. Be sure to try !!!!
