Delivery as always fast - unpack, plug in - work. I had to play around a bit before I had the plastic top which protrudes into the ear set correctly - at first I tried the part so stuck in his ear as the earphones from your phone - but that will not do. Only when looking closely at it occurred to me that these plastic attachments before direct the sound at right angles to the ear and thus only slightly to extend into the ear canal :-) voice quality and earpiece volume are absolutely fine - patients with beards but it can produce noise if the Micro scurries in Bart. A deduction of points there, because you still have to fumble somewhat when setting up the part - unless you have strong jug ears. My recommendation: If the money is absolutely worth it.
