An enormous default, harmful

I purchased this product only to use it as a portable FM radio; I would have really liked to disable Bluetooth related features that make insufficient autonomy in continuous use (between half and three quarters of a day).
A huge flaw: the large center button. You will spend time in rage against this enormous too sensitive button, which engages at the slightest touch, followed by a "DING DING DING" infamous lasting three seconds that cut what you were listening to. Ditto for the discharged battery, its cutting your listening, ditto if you reach the maximum volume. Such a shame! For the reception quality is excellent and the undeniable practicality.
