I received Bluetooth 4.0 Hi-Fidelity Sports Headphones from Francois et Mimi. My son loves head phones and always is looking for something new. I tried these out first before I gave them to him. The sound quality was very good. They were very easy to pair with my phone it only took a few seconds. Works great with almost all tablets and smartphones that utilize Bluetooth technology. My son has been using them at the gym and he loves the bluetooth technology. He said it is much easier to work out with wireless headphones than ones that are connected to his phone.
He says they fit perfect in his ears and they do not fall out. I like that it has a built in microphone and everything can be adjusted in one spot. There is also removable ear clips that you can keep on or take off. I received these bluetooth headphones complimentary in exchange for my unbiased review and opinion. All opinions and words are my own.
