How did we exist in this world before bluetooth? I honestly don’t remember. I find it really hard to work without background noise, so I tend to keep my headphones on and listen to my iPhone the entire day at work. The only problem is that the wire gets in the way. So I bought bluetooth headphones. This is the best thing ever. I keep my phone in my pocket and put the headphones on. It’s even voice controlled. I just touch my ear and say something like "Play songs by Jay-Z" and it starts up. And if someone calls me I touch my ear again and I answer the phone. Why didn’t someone invent this years ago?
