Review on Immerse Yourself in Music with Deep Purple Hi-Fi Over-Ear Stereo Bluetooth Headphones: Built-in Mic for Crystal Clear Phone Calls and Enhanced Noise Cancellation Technology, Complete with Retail Packaging by Marina Knutson

They are amazing. The range is ridiculously long. With a fully charged battery, I can leave my phone on the kitchen table and do chores anywhere, stack laundry on top, go outside and service the pool, even vacuum without encountering playback issues. When the battery gets low it starts to glitch and unfortunately that's the only way to know if the battery is low. The gauge on the phone ALWAYS shows full even when it is low. I don't know what's going on there, but I just charge it regularly. They can get a little uncomfortable after prolonged wear but overall a great pair of cheap blue tooth headphones.
