First the facts: No bluetooth devise is perfect. If you want perfection stick to wired devices. Every bluetooth device has a range limit and the odd drop outs.Overall: In my humble opinion these headphones are the absolute best you will get anyplace for the price. They easily can compete with bluetooth headsets in higher end pricing brackets. If you want solid quality sound and bluetooth these are the real deal.My use: I use these for watching movies (netflix), TV (hulu), and music (pandora and iTunes and Tiny Shark and a host of other companies) I run off my Mac Book Pro and Droid Bionic phone. I love streaming music from my phone while working our. No cords. No tangle ups.Pros:Great quality sound that in my opinion compete with bose headsets i have used is the 150-200 price range.No hiss no humGreat wire free tangle free serviceIncredible battery life!!! WOW these things last way longer then any device i have ever used.Super comfortable fitCons:They are bluetooth so there will be some drop outs (nothing major)Like all bluetooth they have a range (i have to stick within a 12 foot range of connected devices)Not all devices are bluetooth (Kindle for example) make sure you count all the stuff you use to see if they are Bluetooth.Bluetooth is what Bluetooth does! (it is not a perfect technology)The buttons are a little small you have to learn where they are and deal with it.Warnings: A lot of negative reviews here are because people who bought this product did not understand the limitations of Bluetooth products. It is likely you will still end up with wired headphones for some devices. Count the cost-- but if you are sure you want a bluetooth headset with all it flaws and glories this is gonna be the best bang for your buck. I personally could not be happier.
