The good-looking headphones comes in beautiful packaging, with cable and bag. The charging socket with Micro-USB is convenient because today almost every mobile phone / smartphone has the same connection. The connection via the Universal rocker push switch is easy. Only the sound and silent sites of the switch is a bit fiddly to use and not so great to feel, what is not so tragic, but since you already the "transmitter device" adjusts the volume. The connection to my new smartphone (Liquid e700 trio) to my PC, my tablet and a CSL - BT transmitter, the one plugged into the earphone output of any audio device worked right away. The sound is good, the middle of perhaps a little strong, but the bass is fine without rumble. (It crackles and whistles nothing like the cheap BT headphones AEG KH4225, which is abysmal compared to the Arctic) One thing that bothers me for some displays from the Far East, is the much too small printed manual, which I find annoying. The pleasant and good-looking upholstery around headband and ear shells suggests a more comfortable wearing comfort, as I experience it in reality. The size of the ear cups I think is too small, the tension on the strap too large and the Vertstellbarkeit at the temple ends for just under. Only for people with a narrow head and smaller ears. For a well-nourished Central Europeans about 1.82 with hat / helmet size XL the headset is not optimal and pressed after a short time. Is strengthened the uncomfortable wearing when you need a pair of glasses. Technology, sound, compatibility and features good, comfortable in my case rather modest.
