Lets review new in-ear headphones KEF M100. And begin with the fact, that manufacturer among technical details names only facts, that they have 10 mm drivers, that are moved by neodymium magnets, and does not tell information about sounds frequencies range, that they can reproduce, impedance, sensitivity, signal/noise ratio and maximal power input. In the same time manufacturer names lots of “unique” “technologies”, which have little to no technical sense. Price, that manufacturer asks for this device, is 150 USD at the end of Autumn 2015, for 5 – 7 times smaller sum there is ability to buy in-ear headphones with known technical details ( with very good technical details there is need to note, which given model does not have ). So, these headphones KEF M100 and all other devices of this manufacturer are not recommended for purchase, because they are marketing money-pumping from customers for devices, which does not worth them and which has now technical advantages, that are adequate to their price. So, they are not recommended for purchase and it is better to buy in-ear headphones of other manufacturers, which name all technical details of their devices and do not overprice them.
