Does what it is supposed to... WORK!Paired easily with my Blackjack II, sounds great, good noise reduction, no echo.Came with ear hook but I don't need it fits perfectly with the medium ear gel (comes with 3).Great charging options! Charge from AC, USB or AAA battery right out of the box, car charger is available.Attention audiophiles, if your looking for good music response walk away this is designed for voice.That being said, I was surprised at the bass response it did have and works fine for occasional listening.The charging system is my favorite part of this headset you can charge from anything.Attention engineers.. thanks for the foresight in giving the user the options to disable the flashy blue lights.There is no reason to have flashing status lights on a device I CAN'T SEE!To disable the status/online lights press and hold the volume up when powering on the device. Repeat the same steps to turn the lights back on. This is a comfortable well engineered product that works great for what it was designed for TALKING.Attention designers... enough with the flashy blue lights. If you are going to use blue LED's please tone down the intensity or give me the option to disable them. Only con I have is that the buttons are very stiff to press but that helps prevent inadvertent presses. Hopefully the buttons will "break in" over time.
