Review on 🎧 COOMAX Wireless Mini Spy Earphone with Hidden Earpiece Headset and Microphone Detection by Cheska Perry

Once you figure out how to adjust the earbud to the best position, the sound is very clear and works quite well in noisy environments. However, feedback noise (hum, howl) does occur, especially when standing next to large electronic devices. It is beautifully finished and hides very well. The battery life depends a lot on the brand. I've had much more success with the Maxwell brand. I typically get around five hours of life from other brands, but with the Maxwell brand I can get clean sound in around six hours. I can stretch it two more hours but the tone is reduced. The coil connector is best hidden under fully covered clothing. The black hidden power button is a big problem. There is nothing to reinforce or protect the wiring on either end of the switch. All it takes is a good pull and the wiring comes loose rendering the kit useless. The coil connector reminds me of typical in-ear headphones that break after six months of wear. The maximum time I have been able to keep the coil connector running with constant use is three months. I believe it would have lasted much longer if the on/off button had been reinforced with shroud to protect the wiring.
