90° plugs are awesome.

I work in a fabrication shop and so far they have held up very well. Length is just about perfect, phone in my pocket with the other end plugged into my earmuffs. Most of my coworkers use Bluetooth. By the middle of the day they are recharging while I can pretty much keep going the whole shift. The 90° plug is great for keeping side stress off the 3.5mm jack while my phone is in my pocket. I could see it not working if you have a thick/bulky case on your phone tho. The 90° would also be good in a tight spot if you need to plug something in. (Say your device is close to a wall) The cord hanging down instead of straight out keeps stress off the jack as well. It also would also reduce the chance of someone walking too close and breaking the plug/jack if they caught it.
