Review on HIFI WALKER Bluetooth Microphone Earphones by Michaela Hughes

I've been using it for more than a month and it works perfectly. The battery lasts about 6 hours, the sound is clear. Easy to pair with my laptop and phone. It has a range of about 20 feet, at which point the audio begins to drop out. They are very convenient and load quickly. When the battery is almost empty, you will be warned by a voice about 10 minutes before switching off. You don't need to connect the case to charge the headphones.
