Bought for iphone 4s. The seller promised that he would pronounce the name of the caller, read SMS, etc. In reality, he only pronounces names written in English. language, otherwise it says "incoming call from . (pause). answer or reject". SMS is not read. Connects the call and dials with a delay and some kind of beeping in the ear, which became annoying after a month of use. Now the most interesting thing - it broke down after 3 months - when I tried to call or answer a call, I began to chirp in my ear endlessly. Took it for repair under warranty - the accelerometer, which is built in there inside (the function of determining dressing on the ear), failed. not repaired, replaced with a new one. Out of order after 4 months with the same symptoms. frustrated, threw it out. returned to the old Jabra, which lay in the car all winter without recharging, turned it on and immediately everything worked without problems. Bottom line: the device is interesting, stylish, perfectly heard itself and heard me. NO! half of the declared functions do not work with the Iphone and there is simply no reliability for such money. Disappointed.
